The central processing unit 810 is configured to process the audio file to provide a left channel signal 811 and a right channel signal 812. The speaker amplifier 820 is configured to receive and amplify the left channel signal 811 and the right channel signal 812, and output the amplified left signal 821 and the amplified right signal 822.

The resistance detector 85 is used to measure the resistance value of the element contacted by the ring body 841. The multiplexer 86 is configured to receive the amplified right signal 822'. When the resistance value of the element contacted by the annular body 841 is the "preset value, for example, 1 M ohm, the multi-wei _ _ output amplifies the right signal 822" The speaker 83 receives and emits a sound for amplifying the left signal. The sound source output device amplifier 870 is configured to receive and amplify the left channel signal 811 and the right channel signal 812' and output the amplified left earphone signal 871 and the amplified right earphone signal 872. Further, the resistance detector 850 further includes a known resistor 851, a first resistor terminal 852 and a second resistor terminal 853, wherein the first resistor terminal 852 is transferred to the central processing unit 810 and the annular hole 841, and second The resistor terminal 853 is lightly connected to the - supply voltage Vs, wherein the central processing unit 81 is used to determine the voltage division of the first resistor terminal 852. # 纟 When the handheld electronic device is actually used, there are three states in which the sound is emitted. The state is to use the built-in speaker to sound. First, when the user does not insert any sound source output device, the left channel = 811 and the right channel signal 812 are output by the central processing unit 810 to the speaker amplifier 82, and the speaker is amplified. 82〇Amplify the left channel signal 81彳 and the right channel signal 812 and output the amplified left signal 821 and the amplified right signal 822, and then the amplified left signal is divided into the amplified left signal positive pole 8211 and the amplified left signal negative pole 8212, and this is positive When the negative signal is output to the speaker 83, the speaker 830 will play the sound of the amplified left signal 821, which is a single channel. 7 201146025 The second state is the user cup, when the device hole _, The central processing = audio source ^ to determine the inserted audio source output device is precisely by the resistance detection 850 inserted sound source output device for the headset g "resistance example to 5 brothers, assuming the resistance is about 1k ohms" and false / / and The grounding of the fourth section of the plug is 2.2k. After derivation, the first; resistance:, 851 (four) [11 < /, 2.2 | 〇] > ^ 0.3125 = 852 partial pressure is about when the central processing unit 810 knows the flute ^ 0 · 3125XVS, the central processing β The partial pressure of the resistor terminal 852 is approximately that the resistance value of the contact element is about H, and the value of the annular body 841, J and 1 k ohm can be inversely derived. Then the central processing is crying: PIO control multiplexer • At this time, the multiplexer receives the amplified right-right headphone signal 872 output by the two-source output device amplifier 87G, and the inserted device, for example, Μ put this = big left earphone The signal 871 and the amplified right headphone signal 87 are inserted into the sound source output device "source output device hole 840", and the central processing unit 850 determines the resistance of the inserted sound source output device. The second set device is inserted into the sound source output device. The grounding resistance is about two; 电 The electric resistance of (4) 51 is about the heart's derivation. It can be known that the partial voltage of the second (four) 852 is [1k/(1k+1M)] xVsq side μ. Therefore, when the central processing unit 81 〇 When the partial pressure of the first-resistor terminal 8 5 is 〇.〇〇1×VS, it can be reversed that the contact value of the annular body 841 is about 1 M ohm. At this time, the central processing unit 810 transmits GP 丨 0 815. The control multiplexer causes the multiplexer 860 to receive and output the speaker amplifier 82 〇 wheel 201146025 1 VV ^0^01 f\ to amplify the right signal positive pole 8221 and the amplified right signal negative pole 8222 to the inserted sound source output device; The inserted component 'for example is a paper speaker, will be amplified The sound of the number 822. At the same time, the speaker writes the amplified crying 820 output to amplify the left signal positive pole 8211 and the amplified left signal negative pole 8212 to the speaker 830, then the speaker 830 emits a sound that amplifies the left signal 821.

Go to step S930, when the central processing unit 810 determines that the resistance value of the contact element is the second preset value, the process proceeds to step S950. In step S950, the sound source output device amplifier 870 receives and amplifies the left channel signal 811 and the right channel. The signal 812' is rotated to amplify the left earphone signal 871 and the right earphone signal 872 is amplified, and the multiplexer 860 outputs the received amplified left earphone signal 201146025 I vvj〇; 7〇rrv ' r 871 and the amplified right earphone signal 872 to The sound source output device causes the inserted component to play the sound of the amplified left earphone signal 8 71 and the amplified right earphone signal 872. Returning to step S930, when the central processing unit 810 determines that the annular body 841 is not in contact with any of the sound source output devices, it proceeds to step S960. In step S960, the speaker amplifier 820 receives and amplifies the left channel signal 811 and the right channel signal 812, and outputs the amplified left signal 821 to the speaker 830, and the speaker 830 plays the 821 sound that amplifies the left signal. The stylus with a paper speaker described in this embodiment uses a hollow space inside the stylus itself to simplify the flexible ultra-thin speaker (paper speaker) technology, and the paper speaker is built in the stylus.

Please refer to FIG. 10, which is a schematic diagram showing the insertion of a plug of a stylus with a paper speaker into a handheld electronic device. Moreover, since the paper speaker has a space between the inner surface and the inner surface, the paper speaker does not lie flat on the outer surface of the stylus, and the sound emitted has a better sound quality. In addition, the stylus may have an opening and one or two U-shaped plates in addition to a plurality of openings, and the paper speakers are disposed on the opening and the U-shaped plate. In this way, when the U-shaped board is opened, the paper speaker can emit sound more in a specific direction, so that the sound quality of the paper speaker is better. Furthermore, the handheld electronic device of the present embodiment couples the output of the speaker amplifier to the speaker and the multiplexer, so that when the central processing unit 201146025 • *» r\ determines that the audio source device is inserted into the handheld device The sound source output device hole of the electronic device, and the fourth segment of the plug of the sound source output device is divided into the first pre-sighing value, the amplified left signal and the amplified right signal output by the speaker amplifier are respectively used by different speakers.
