This sound setting can be set individually or individually for each group. -9- This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) 1246343

First, the user operates a specific key, which will be stored in! Communication The person name, phone number, and email address set in the green first group are displayed on the screen of the liquid crystal display 8. Then, the effect on / off setting of the person and group and the position for inputting the effect type will be displayed on the screen. With this book, users can set sound effects on / off and input sound types individually or in groups. The relevant input data of the sound effect on / off and sound effect type will be stored and set in the address book of RAM3. After the first group is set, continue to set the sound effect on / off and sound type of the second group and the third group. In the example shown in Figure 4, the personal sound effects and groups of the first group are set to 0FF (indicated by "X" marks on the screen), so those who belong to the first group will not perform sound effects. deal with. The group of the second group is set to ON (indicated by a "0" mark on the screen), and the effect type is set to "Echo 1". Therefore, the incoming call from the second group will be processed with the echo of 1. Although the group setting of the third group is 0 F F, the personal sound effect is set to ON, and each person has set a different sound effect, that is, “Distosion”, “Hybrid 1”, and “Echo 3”. In addition, the same setting can be used in each group. The advantage of doing so is that the user's setting operation will be easier and simpler. ‘When the action gas 5 tongue is on standby and there is an incoming call’ will be detected by the communication unit 10, and the flow moves from step S1 to step s2. That is, the communication unit i 〇 notifies the CPU 1 of the caller's phone number, and the CPU 1 stores the caller's phone number in the RAM 3 again. Next, in step S3, the CPU1 compares the phone number set in the RAM3 address book with the caller's phone number, and detects the sound effect on / off and the type of sound effect set by the phone number. The paper size applies the Chinese National Standard (CNS) A4 specification (21 × 297 mm) 1246343 A7 B7 V. Description of invention (8). For example, if the caller belongs to the first group, the sound effect is detected as OFF. If the caller belongs to the second group, the group sound will be detected as "Echo 1". If the caller belongs to the third group, the type of sound effect set by each person will be detected. Next, the flow moves from step S3 to step S4, and the CPU 1 outputs the detected sound-related data to the music player section 12 via the bus 7. This data is supplied to the sound generating circuit 2 3 through the interface 15 shown in FIG. 2.

If the result of the determination in step S7 is "No", the process moves to step S8, and it is determined whether the user operates the number keys. If the result of the determination in step S8 is "NO", the process returns to step S6, and the above determination is performed again. That is, the CPU 1 continues the above judgment until the judgment result of any of steps S6 to S8 is "YES". When the user listens to the ringtone of an incoming call, if he wants to change the sound effect, he can press the predetermined number key to change the sound effect quickly. When the user presses the number key, the judgment result of step s 8 is "YES", and the flow moves to step S 9. Here, because the sound effect corresponding to the number key has been set in advance, the sound effect corresponding to the number key pressed by the user will replace the currently set sound effect for incoming calls, except that it is set on the sound effect generating line 2 3, and will automatically Change the settings stored in the RAM3 address book. This allows the user to simply change the sound effect assigned to the ringtone of the incoming call simply by operating the desired number keys. When the ringtone is played by the autophone, the sound effect change screen shown in Fig. 6 will be displayed on the screen of the LCD display 8. This screen will show the notification message of "Calling 丨", as well as the song title and type of sound effect. In addition, in order to facilitate the user to operate the number keys, the types of sound effects corresponding to the setting of each number key are enumerated. As shown in Figure 6, the ringtone is currently played by "Reverb 丨", so the user is informed that the sound effect is designated by the number key "丨": Therefore, if the user wants to change the type of sound effect, he only needs to press the desired number Key. In addition, press the number key "〇" to set the sound effect to 0 ~ {7. In FIG. 5 ’, the user presses the button # to hang up the phone, and the judgment of step S7 is -12 ·
