When we are talking normally or listening to MP3 normally, the analog switch 12' is controlled by (10)1{) to switch the output of the analog switch 12 to the LINEJNP and LINEjNM interfaces of the cpu. When we want to play music during a call, we can switch the output of the analog switch 丨2 to the MIC + and MIC of cpu 1〇. As shown in Fig. 3, it is an exemplary diagram of the analog switch 12 of Fig. 1 of the present invention. Analog switch 12 includes input pins A1, A2, output pins B1, Cl, B2, C2 and control pins s ^ Input pin A1 through the control pin § output pin Bl, C1 selection, input pin A2 The output pins B2 and C2 are selected by the control pin s. Control pin s is connected to the switch control pin 13 of the mobile phone 1 'When the control pin S is high level, the input pin A1 is connected with the turn-out pin C1'. The input pin A2 is connected with the output pin C2; when the control pin is When S is low, input pin A1 is connected to output pin B1, and input pin A2 is connected to output pin B2. 100116593 Form No. A0101 Page 7 of 20 1002027847-0 201246897 [0018] The input pins A1 and A2 are connected to the pins MP3_OUTL and MP3_OUTR of the external MP3 chip 11 through the CAP 20 and the CAP 21, respectively. The round pins B1 and B2 are connected to the pins MIC+ and MIC of the CPU 10 through the CAP 19 and the CAP 18 respectively; the output pins ci and C2 are connected to the pins LINE_INP and LINE_INM of the CPU 10 through the CAP 16 and the CAP 17 respectively. [0019] When we are talking normally or listening to MP3 normally, the level of the switch control pin 13 is triggered to a high level by the CPU 10, so that the control pin s is at a high level 'At this time, the input in the analog switch 12 is cited. The pins A1 and A2 are connected to the output pins C1 and C2, so that the output of the analog switch 12 is switched to the LINE_INP and LINE_INM interfaces of the CPU 10. The circuit signal flow at this time is • external MP3 chip 11 --> analog switch 12 --> LINE pin of CPU 10 --> MIC pin of CPU 10 (the process of LINE pin to MIC pin) The circuit μ is switched by the internal switching circuit of the CPU. At this time, the LINE pin of the CPU 10 can only transmit a kind of sound because of the lock of the circuit performance. Therefore, it is impossible to transmit music during the call. The LINE pin of the CPU 1 refers to the pins LINE_INP, LINE_INM, and the MIC pins of the CPU 10 refer to the pins MIC+, MIC-. [0020] When we want to play music during a call, the level of the switch control pin 13 is triggered to a low level by the CPU 10, thereby causing the control pin s to be low level 'At this time in the analog switch 12 The input pins A1, A2 are connected to the output pins B1, B2 'switching the output of the analog switch 12 to the MIC + and MIC on the CPU 10' to cause the MP3 signal to be input to the CPU 10 through the MIC.

Since the MIC pin can transmit two kinds of sounds at the same time, the purpose of playing MP3 during the call can be achieved. As shown in Fig. 4, it is a functional block diagram of the music control unit 3 in the figure of the present invention. The music control unit 3 includes a detection module 301, a control module 313, a detection module 303, and a control module 2-3. The detecting module 301 is configured to detect the cpu 1〇 during the call, and determine whether the mobile phone 1 needs to play music during the call according to whether the CPU 10 controls the external MP3 chip to play music through the interface. When it is not detected that the mobile phone 1 has a need to play music during the call, no processing is performed. When there is a need to play music during a call, that is, when the CPU 10 detects that the player's play button is pressed, the external MP3 chip 11 is controlled to play music through the I2C interface. The I2C interface is as shown in FIG. 2, and the SM and SCL interfaces of the CPU 10 and the external MP3 chip 11. The control module one 302 is configured to trigger the level of the switch control pin 13 to be low level by the CPU 1 after detecting that the mobile phone has a need to play music during the call. At this time, the output of the analog switch 1 2 is switched to the MIC + and MIC of the CPU 10. [0025] The detecting module 303 is configured to detect the cpu 1〇 during the call, and determine whether the mobile phone 1 needs to pause the music playing or whether the music is played according to whether the CPU 10 no longer controls the external MP3 chip to play music. Finished. When there is no need to pause music playback or the music has not finished playing, continue to detect. When it is necessary to pause the playback of the music and when the music is played, the CPU 1 detects that the pause button of the player has been pressed or the player has cut 100116593 Form No. A0101 Page 9 / Total 20 Page 1002027847-0 201246897 Change to stop At this time, the CPU 10 disconnects the connection with the external MP3 chip u, and the external MP3 wafer 11 is no longer controlled. Just (4) Charm 2__ triggers the level of the switch control pin to a high level by the CPU 10 when it is necessary to pause the music or after the music has been played. At this time, the output of analog switch 12 is switched to cpu 1 (^UNE_INp and LINEJNM interface. 圃2 It should be noted that during the call, the music is played as background music, at this time, the call is still It can be performed normally, but the quality of the call will be reduced. The picture shown in Figure 5 is a flow chart of a preferred embodiment of the method for playing music during a call by the mobile phone of the present invention. 0) 029] Step S1' During the call, the test module detects the (10) (10) line and determines whether the mobile phone i has the need to play music during the call according to whether the CPU 1 controls the external Mp3 chip to play music through the interface. s Detecting that the mobile phone 1 has a need to play music during the call, perform step S1 01 ’ when there is no debt measurement to the mobile phone! When there is a need to play music during a call, do nothing and end the process directly. In the country #STEP S101, the control module 3〇2 detects the need for the mobile phone j to play music during the call, and triggers the level of the switch control pin 13 to be low through the cpu 1〇. At this time, the output of the analog switch 12 is switched to the MIC + and MIC- of the cpu 10. Step S102, during the call, the detection module 2〇3 determines whether the cpu 1〇 no longer controls the external MP3 chip to play music according to whether the cpu 1〇疋 has disconnected from the external MP3 chip u. That is, whether you need to pause the sound 100116593 Form No. A0101 Page 10 / Total 20 pages 1002027847-0 [0031] 201246897 Music playback or music has been released. #要(四) Stopping the sound After the playback is completed, step S103 is performed, and when there is no need to pause the music or the music is not played, the detection is continued. 3, the control module 2 3Q4 triggers the level of the switch control pin 13 to the intermediate level by the CPU 10 when the music needs to be paused or after the music is played. At this time, the output of the analog switch 12 is switched to the LINEJNP and LINE_INM interfaces of cpu j 。. [0033] In summary, the present invention complies with the requirements of the invention patent, and applies for a patent 爰 according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are Should be covered by the following patent application. .
