Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides an audio transmission method, which is applied to first electronic equipment, wherein the first electronic equipment can be equipment capable of transmitting audio, such as a mobile phone, a tablet personal computer, a vehicle-mounted computer, an electronic book reader, an MP3 player, an MP4 player, a laptop portable computer, a desktop computer, an intelligent television and a wearable equipment, and the embodiment is not limited to the examples.
Referring to fig. 1, fig. 1 is a flowchart of an audio transmission method according to an embodiment of the present invention, as shown in fig. 1, the audio transmission method includes the following steps:
As will be readily appreciated, the audio file may be a song, audio in a video file, or the like; the audio file may be stored in the first electronic device or may be an audio file contained in an application of the first electronic device. In other embodiments, the audio file may also be referred to as a sound source file, sound source information, sound file, or the like.
In this step, the first electronic device may decode the audio file into the first channel audio signal and the second channel audio signal in a case where the audio file is acquired. Alternatively, the first channel audio signal may refer to a left channel audio signal and the second channel audio signal may refer to a right channel audio signal. For example, the first electronic device may decode the acquired audio file, decoding the audio file into a left channel audio signal and a right channel audio signal. It is noted that each sub-file in the audio file carries a left channel audio source identifier or a right channel audio source identifier, so as to facilitate the identification of the sub-file by the first electronic device, so as to decode the audio file into a left channel audio signal and a right channel audio signal. The specific decoding operation of the audio file by the first electronic device may refer to related technology, which is not described in detail in this embodiment.
It should be noted that the second electronic device may refer to an audio playing device, such as an earphone, a sound device, or the like, that can receive the audio file and play the audio file.
In the embodiment of the present invention, after decoding the audio file into the first channel audio signal and the second channel audio signal, the first electronic device may transmit the first channel audio signal to the first wireless chip, encode the first channel audio signal through the first wireless chip, and send the encoded first channel audio signal to the first channel playing device of the second electronic device through the first wireless chip.
And 103, encoding the second sound signal through a second wireless chip and then sending the second sound signal to a second channel playing device of the second electronic equipment.
It can be understood that the first electronic device encodes the second channel audio signal through the second wireless chip and then sends the encoded second channel audio signal to the second channel playing device of the second electronic device, so that the audio file can be decoded into two parts and sent through the two wireless chips respectively. Therefore, compared with the existing audio files which can be sent only through one wireless chip, the scheme provided by the embodiment of the invention expands the transmission channel of the audio by one time, is more beneficial to the transmission of the audio files with large data volume, and ensures the transmission quality of the audio files.
Optionally, the first wireless chip and the second wireless chip are both bluetooth chips. Like this, on the basis of current bluetooth and bluetooth agreement, first electronic equipment can decode into two parts through setting up two bluetooth chips with audio file, encode and transmit respectively through two bluetooth chips, just so also with the transmission channel of audio in the first electronic equipment expanded one time, transmission bandwidth has also promoted one time, and then can not need compress the operation to audio file, can not cause audio file's tone quality impaired, guaranteed audio file's transmission quality, guaranteed audio file's broadcast effect, bring better hearing experience for the user.
Optionally, in a specific embodiment, the first channel audio signal is a left channel audio signal, the second channel audio signal is a right channel audio signal, the second electronic device is an audio playing device, the first channel playing device of the second electronic device is a left channel playing device, and the second channel playing device is a right channel playing device. For example, the first wireless chip is a first bluetooth chip, the second wireless chip is a second bluetooth chip, and the audio playing device is a bluetooth headset, so that the left channel playing device of the bluetooth headset is a left headset, and the right channel playing device is a right headset. In this embodiment, the first electronic device may decode the audio file into a left channel audio signal and a right channel audio signal, encode the left channel audio signal by using the first bluetooth chip, and then transmit the encoded left channel audio signal to the left earphone of the bluetooth earphone, encode the right channel audio signal by using the second bluetooth chip, and then transmit the encoded right channel audio signal to the right earphone of the bluetooth earphone.
It should be noted that, the transmission bandwidth of bluetooth is about 3Mbps, and in the case of only one bluetooth chip, this limits the available transmission bandwidth of the left and right channel audio signals to a maximum of 1.5Mbps. According to the scheme provided by the embodiment of the invention, the first electronic equipment can respectively send the left channel audio signal to the left earphone of the Bluetooth earphone and the right channel audio signal to the right earphone of the Bluetooth earphone through the two independent Bluetooth chips, so that the left channel audio signal and the right channel audio signal can both enjoy the transmission bandwidth of 3Mbps, the transmission bandwidth of the audio file is improved, the transmission quality of the audio file is ensured, and the tone quality of the audio file is prevented from being damaged.
In addition, the first electronic equipment can respectively send the left and right channel audio signals to the corresponding left and right earphones according to the playing characteristics of the Bluetooth earphone, compared with the existing Bluetooth earphone, which receives the packed files comprising the left and right channel audio signals compressed together, the Bluetooth earphone does not need to decompress the audio files and extract the corresponding left and right channel audio signals after decompression, and the processing operation of the Bluetooth earphone on the audio files is simplified.
It should be noted that, the above is only an example of a specific embodiment of the present invention, and the first Wireless chip, the second Wireless chip and the audio playing device in the present invention may be other embodiments, for example, the first Wireless chip and the second Wireless chip may be Wireless-Fidelity (WIFI) chips, ultra Wideband (UWB) chips, or the like; the second electronic device may also be a wireless sound, such as a bluetooth sound, etc.
Alternatively, since the first channel audio signal and the second channel audio signal are encoded and transmitted through the first wireless chip and the second wireless chip, respectively, the encoding and the transmitting of the first channel audio signal by the first wireless chip may be performed simultaneously with the encoding and the transmitting of the second channel audio signal by the second wireless chip, or may be performed separately based on the operating state of the second electronic device.
For example, when the second electronic device is an earphone, the left channel playing device is a left earphone, and the right channel playing device is a right earphone, the first electronic device may acquire working states of the left earphone and the right earphone, and then execute corresponding operations according to the working states of the left earphone and the right earphone. Specifically, the step 102 may include:
when the left earphone of the earphone is in a use state and the right earphone of the earphone is in an unused state, the left channel audio signal is encoded by the first wireless chip and then sent to the left earphone;
the step 103 includes:
and under the condition that the right earphone of the earphone is in a use state and the left earphone of the earphone is in an unused state, the right channel audio signal is encoded through the second wireless chip and then sent to the right earphone.
Optionally, the left earphone and the right earphone may be respectively provided with a start switch, if the start switch is turned on, the corresponding left earphone or right earphone is in a use state, and if the start switch is not turned on, the corresponding left earphone or right earphone is in an unused state. The first electronic device may learn the working state of the headset through a signal sent by the headset. Alternatively, the left earphone and the right earphone of the earphone may be respectively provided with an infrared sensor, and whether the left earphone or the right earphone is in contact with the left ear or the right ear of the user is detected by the infrared sensor to determine whether the left earphone and the right earphone are in a use state or a non-use state.
For example, when the contact between the left earphone and the left ear of the user is detected and the right earphone is separated from the right ear of the user, the user is indicated to be using the left earphone at the moment or needs to use the left earphone, and the first electronic device encodes the left channel audio signal through the first wireless chip and then sends the encoded left channel audio signal to the left earphone; when the right earphone is detected to be contacted with the right ear of the user and the left earphone is separated from the left ear of the user, the user is indicated to be using the right earphone at the moment or needs to use the right earphone, and the first electronic device encodes the right channel audio signal through the second wireless chip and then sends the encoded right channel audio signal to the right earphone. Therefore, the corresponding left and right channel audio signals can be sent according to the working states of the left and right earphones in the earphone, when the left earphone or the right earphone is in the unused state, the audio signals can not be sent to the left earphone or the right earphone, and further unnecessary transmission bandwidth can be avoided, and the use power consumption of the first electronic equipment is reduced. Of course, if the left earphone and the right earphone are both in the use state, the first electronic device can send the encoded left channel audio signal to the left earphone through the first wireless chip, and send the encoded right channel audio signal to the right earphone through the second wireless chip.
According to the audio transmission method provided by the embodiment of the invention, the first electronic device can decode the audio file into the first sound channel audio signal and the second sound channel audio signal, encode the first sound channel audio signal through the first wireless chip and then send the encoded first sound channel audio signal to the first sound channel playing device of the second electronic device, encode the second sound channel audio signal through the second wireless chip and then send the encoded second sound channel audio signal to the second sound channel playing device of the second electronic device. Therefore, the audio transmission channel in the first electronic equipment is doubled, the transmission bandwidth is doubled, the transmission quality of the audio file can be improved, the playing effect of the audio file is ensured, and better hearing experience is brought to the user.
In order to better understand the scheme of the embodiment of the present invention, a specific description will be given below taking a first wireless chip as a first bluetooth chip, a second wireless chip as a second bluetooth chip, and a second electronic device as a bluetooth headset. Referring to fig. 2, the first electronic device transmits the decoded audio file through Pulse code modulation (Pulse CodeModulation, PCM) to form a left channel audio file (L) and a right channel audio file (R), processes the left channel audio file (L) through a first bluetooth chip, and processes the right channel audio file (R) through a second bluetooth chip.
Specifically, the first Bluetooth chip receives a left channel Audio file (L) through a sound Audio application layer; the left channel Audio file (L) is encoded by the bluetooth Audio transmission model protocol (Advanced Audio Distribution Profile, A2 DP) and the Audio/video transmission protocol (Audio/Video Distribution TransportProtocol, AVDTP) between bluetooth devices and transmitted to the left earpiece of the bluetooth earpiece by the baseband unit and the radio frequency unit. It should be noted that, the first bluetooth chip further includes other protocols and control layers, such as session description protocol (Session Description Protocol, SDP), switchable media access controller and Physical layer (Alternate Media Access Controller/PhysicalLayer, AMP), logical link control and adaptation layer protocol (Logical Link Control and AdaptationLayer Protocol, L2 CAP), human-computer interaction (Human-Computer Interaction, HCI) control plane, link management protocol (Link Manager Protocol, LMP), bit stream (BT) baseband control layer, port Physical layer (PHY), etc., and the specific working principle of the first bluetooth chip may be referred to the related art, which will not be described in detail in this embodiment. In addition, the related structure and working principle of the second bluetooth chip are consistent with those of the first bluetooth chip, and reference may be made to the above description, which is not repeated in this embodiment. After receiving the right channel audio file (R), the second Bluetooth chip encodes the right channel audio file based on the related Bluetooth protocol and Bluetooth technology and transmits the right channel audio file to the right earphone of the Bluetooth earphone. Therefore, the first electronic equipment can respectively transmit the left channel audio file (L) and the right channel audio file (R) through the two Bluetooth chips, the audio transmission channel of the first electronic equipment is expanded, the transmission quality of the audio file can be improved, the damage to the tone quality of the audio file is avoided, and the tone quality effect of the audio file is ensured.
