If there is a chemical formula in this case, please disclose the chemical formula that best shows the characteristics of the invention: No. 6. Description of the invention: [Technical field of the invention] The present invention relates to a sound transceiver and a detection method thereof, particularly A voice transceiver for a mobile phone and a method for detecting the same. [Prior Art] As shown in FIG. 1A and FIG. 1B, in the case of a mobile phone using the Qualcomm platform, after inserting the conventional sound transceiver 2, one of the sound transceiver sockets of the mobile phone The bias source (HSET-BIAS) 10 is connected to a microphone 20 in the conventional built-in transmitter 2, and since the AC impedance of the team is about 2K when the radio is received, the DC impedance value range is usually larger than the stomach benefit 20 5ΚΩ', the current detected by the bias source 10 is i.8V/(equal to, KQ +5 ΚΩ) = 250uA, less than the minimum detection value of the bias source 1〇3, so the sound transceiver 2 cannot be detected. This action. Therefore, the sound transceiver 2 is inserted into the mobile phone detection method, and after the sound transceiver 2 is driven, the second insertion 23 is pressed in parallel with the sound receiver 20, so that the two ends of the sounder 20 are short-circuited. The load of the voltage and switch is only 2.2ΚΩ, and the current of the source 10 J on the bias source 10 is 201123928 • ^8...2·2 ΚΩ== 8 is #A , which is within the detection range of the bias source 10. (30〇4~1.5 domain), so after the switch 23 is pressed, the bias source can be promptly _to "press", and the corresponding two interrupt notifications are generated - the processor responds accordingly. ^ Please refer to Figures 2A and 2B, which are schematic diagrams of conventional four-segment ϊ曰 transceiver plugs and sockets. Conventional sound transceiver plugs and sockets are common 2 5mm or 3 5mm sound transceiver plugs. • & sockets are such four-segment sound transceiver plugs and sockets. The sound is received, the plug is sequentially contacted with the elastic piece of the sound transceiver socket, and the sonar transceiver plug corresponds to the pin of the sound collector 20 and the loudspeaker 22 is 210 and 21, and the pin of the socket corresponds to the audio input circuit 13 And the pins of the audio output circuit 12 are respectively ,!, when the sound s transmits and receives $2, the microphone pin 211 of the sound transceiver 2 plug first contacts the sound receiver pin of the sound transceiver socket ^ 1〇, since the impedance of the loudspeaker 22 is small (maximum 15 〇Ω), it can be seen according to the connection condition of the foregoing circuit, when the two loudspeakers ΜV and the ground are connected, the bias source 1〇 at this time The current is υν/2 2 ΚΩ + (〇.15 + 0.15) ΚΩ = 720uA, which not only exceeds the minimum value of current detection, but also corresponds to the current when OFF 23 is pressed. Since the action of the sound transceiver 2 is slower than the processor processing time, it is possible to detect not only the sound transceiver 2 is inserted but also the switch 23 when the sound transceiver plug is inserted. , resulting in misuse. 201123928 [Summary of the Invention] In view of the above-mentioned prior art, the purpose of providing a sound transceiver and the purpose of the first is to use the Eight Diagrams to move the sword, causing the problem that the telephone is misjudged.

If the current value does not meet the interval value, the Qian test circuit continues to detect. 201123928 wherein: if the processor receives the first signal, the method further includes the following steps: detecting whether the current value is greater than the interval value, and if the current value is greater than the interval value, sending a second signal to the processor, the second signal The switch is to press the sound transceiver; if the current value is less than the interval value: u sends a third signal to the processor, and the third signal is the sound transceiver is pulled out of the electronic device. If the processor receives the second signal, the method further includes the following steps: detecting whether the current value is smaller than the interval value, and if the current value is less than the interval value, sending the third signal to the processor; if the current value is not less than The interval value is detected by the detection circuit. According to the present invention, the sound transceiver and the detection method thereof have the following advantages: · The sound transceiver and the detection method thereof are achieved by newly designed internal circuits of the sound transceiver The two purposes of detecting the sound transceiver insertion and detecting the switch pressing are eliminated, and no complicated side circuit is required, thereby reducing the cost. [Embodiment] Please refer to Fig. 3, which is a circuit diagram of a sound transceiver of the present invention and a circuit diagram of a conventional sound transceiver socket. The sound transceiver 3 as shown in the figure comprises a first far pile crying μ, a ^^ joint state 30, a plurality of sound reinforcements 31 and U 32. The loudspeakers 3 are respectively connected to the amplifiers of the first connector 30, and the microphones are connected in parallel with a switch 34.

The sound transceiver detection method is applicable to an electronic device. The electronic device includes a processor and a detection circuit. The detection circuit further includes a bias source. The method includes the following steps: at step (S1) The detecting circuit detects whether a current value meets an interval value, and if so, sends a first signal to a processor in step (S2), and then in step (S3), the detecting circuit detects whether the current value meets the interval value, If not, it is detected in step (S4) whether the current value is greater than the interval value, and if so, a second signal is sent to the processor in step (S5), and the process proceeds to step (%). In step (S6), the detecting circuit detects whether the current value is smaller than the interval value, and if so, sends a third signal to the processor in step (S7), and returns to step 5 (S1). The current value is generated by the DC bias voltage generated by the bias source, and the sound transceiver is different from the electronic device: the number is the signal inserted by the sound transceiver, and the second signal is the pressing switch. The signal, and the third signal is the signal that the sound transceiver is disconnected; in addition, in this embodiment, the interval value is 300# A~500 to A, but not in the limit 'the system can be adjusted differently. If the current value detected in step (S1) does not meet the interval value, the detection circuit continuously detects the current value; and if the current value of the debt and the step (S3) meets the interval value, the detection is performed. The circuit continuously detects the current value ^ = 201123928 The current value detected by the step (S6) is not less than the interval value, so that the detection circuit continuously detects the current value. Thus, when an ordinary 2.5 mm or 3.5 mm sound transceiver socket 1 is used as the interface, the present invention can still detect the sound transceiver 3 insertion 'and can effectively prevent the sound transceiver 3 from being inserted during insertion due to the plug and the socket False detection caused by misalignment contact 'Because the current value 720uA generated during the insertion of the sound transceiver 3 is excluded from the interval value (300# A to 500#a), the current value is obtained after the sound transceiver 3 is stably inserted. The judgment of the sound transceiver insertion 3 is made when the temperature is stabilized at 440 uA, and the problem of misjudgment during the insertion process is solved. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
