Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to car audio mute circuits, and in particular, to car audio equipment. Car audio interlock suitable for muting without having to operate all at once Regarding the mute unit.

0002

[Prior art]

An example of a conventional car audio mute device is the one shown in Figure 5. was provided.

0003 In the figure, 13 is a car audio device, and 14 is a mute switch.

0004 How to mute the car audio The front panel of the car audio device 14 The operator now has to operate the mute switch 15 provided at each time. there was.

[Problem that the idea aims to solve]

However, in conventional car audio, as shown in Fig. Attempting to mute the mute switch 15 provided on the front panel of the main unit 14 For example, if you are listening at a toll booth on an expressway while driving, If you want to mute the music source for a short period of time, you can instantly press the mute switch 15. It is difficult to operate the mute switch 15 if you are not used to it, and it is difficult to operate the mute switch 15. There was a drawback that being distracted and unable to concentrate on driving was extremely dangerous.

[0005] This idea was made in view of the above points, and its purpose is to Eliminates the drawbacks of the conventional model and allows car ordering by simply opening the driver's side window of the vehicle. A car audio interlocking mute unit that mutes the audio signal of the audio system. It is located in a place that provides services.

[0006]

[Means to solve the problem]

The car audio interlocking mute unit of this invention is installed on the front panel. has an attenuator switch, and by operating the attenuator switch, A car audio device configured to mute the audio output during playback. , there is a screen inside the door lining on the driver's side of the vehicle that detects when the window is opened/closed (up/down). A sensor is installed in the switch area, and the sound is generated by the output signal from the switch or sensor. It is configured to mute the output.

[0007]

[Effect]

According to this invention, an attenuator switch is provided on the front panel. You can mute the audio output during playback by operating the attenuator switch. In a car audio system that is configured to A switch or sensor that detects the opening/closing (up/down) of the window is installed inside the window, and the switch The switch area is configured to mute the audio output depending on the output signal from the sensor. For example, you can turn off the sound source you were listening to at an expressway toll booth for that time. If you want to reduce the noise, just open the window and do nothing else at once. You will be able to perform your functions and concentrate on driving the vehicle.

【Example】

Examples of the interlocking mute unit for car audio according to this invention are shown in FIGS. The explanation will be based on 4.

[0009] Figure 1 is a perspective view of the interlocking mute unit of this invention, and Figure 2 is the interlocking mute unit. Figure 3 is a cross-sectional view of the vehicle door with the mute unit installed on the door steel plate opening. The enlarged view, Figure 4, shows the controller relay unit connected to the car audio main body and speakers. The circuit diagram inserted between the two, Figure 5, shows the conventional mute switch installed on the front panel. FIG. 3 is a front view of the car audio.

0010 In the figure, 1 is a switch, 1a is a switch lever, 2 is a switch lead wire, 3 is the switch mounting bracket, 4 is the switch output line, 5 is the switch mounting hole, 6 is the switch J mounting bracket suction surface, 7 is door steel plate opening, 8 is door steel plate, 9 is vehicle door external sheet metal , 10 is the window glass, 11 is the window glass lifting holder, 12 is the door lining, 15 is the controller It is a relay unit.

[0011] The configuration of the mute unit is as shown in Figure 1. Attach one end of switch lead wire 2 to the tip of switch lever 1a, and then The tip of the other end of gold 2 is rounded into a circle, and the tip of the other end of the metal The body has a structure in which it is mounted at right angles to the switch mounting bracket 3.

0012 The structure for mounting the mute unit configured as above on the vehicle door is as follows: , the upper side of the door iron plate opening 7 of the door iron plate 8 inside the door lining 13, as shown in FIG. Attach the switch mounting bracket suction surface 6 so that the switch lead wire 2 is on the window glass 10 side. (The switch mounting hole 5 may be fixed with a screw.)

[0013] Then, the tip of the switch lead wire 2 is caught on the upper part of the window glass lifting holder 11. It has become so.

[0014] When the window glass 10 is closed, the window glass lifting holder 11 is raised upward. Therefore, the switch lead wire 2 is also raised upward and the switch lever 1a is moved upward. Turn off microswitch 1.

[0015] Also, when the window glass 10 is opened, the window glass lift holder 11 descends downward, and Accordingly, the tension of the switch lever 1a of the switch lead wire 2 lowers the Since the microswitch 1 is lowered in the opposite direction, the microswitch 1 is turned on.

[0016] As mentioned above, micro switch 1 turns on and off when the window opens and closes, so the Connect the switch output line 4 of the cross switch 1 to the back panel of the car audio unit. , by connecting to the external mute terminal connected in parallel to mute switch 15. It can be muted when the window is opened.

[0017] Also, there is no external mute terminal on the back panel of the car audio unit. In this case, the controller relay unit 15 as shown in Figure 4 is connected to the power amplifier output. and the speaker, and the switch output line 4 from the micro switch 1 is I decided to change the connection of micro switch 1 so that it becomes OPEN when it is opened. Therefore, when the window is opened, the relay in the controller relay unit 15 becomes OPEN, and the By inserting a resistor between the power amplifier and the speaker, mute operation can be performed.

[0018] Also, connect the main switch to the switch output line from this unit to It is also possible to disable the operation of the port.

[0019] In addition, in this embodiment, the mute of the audio output of the car audio is controlled by opening and closing the window. However, using the same switch output line, for example, the air conditioner It is also possible to incorporate it as one of the data signals of autolouver control. .

[0020]

[Effect of the idea]

According to the interlocking mute unit for car audio according to this invention, the above-mentioned Since it is configured as follows, the following effects are achieved.

[0021] The car audio is muted simply by opening the window, so the driver can You can concentrate on driving without being distracted by the panel, which has the effect of improving safety.

[0022] Window opening/closing is detected directly inside the door lining, so it can be used on manual cars and power windows. It can be installed on any vehicle, so it has a wide range of applications.

[0023] A mute terminal can be added by making the relay controller unit a separate unit. Compatible with all car audio systems that are not currently available.
