Of course, the earphone 1 can also be used as part of the audio playback device 2. The sensor 102 may be temperature sensing: a port pressure sensor and a capacitive sensor. The detecting unit 203 can be used to convert the sensor state into an output frequency signal, such as a temperature frequency converter, a pressure frequency converter, and a capacitance frequency converter. Therefore, the sensor state can be relatively "according to the types of sensors 1〇2a, 1〇2b, type and detection unit 2〇3 provided on the headphone bodies 1〇3a, 1〇3b, 相对The human body temperature state can also be a pressure state or a sense capacitance state. 200835380 ' For example, when the sensor 102 is a temperature sensor, the detecting unit 203. may be a temperature frequency converter for converting the state of the temperature sensor, that is, the human body temperature state, into a corresponding frequency value. The microprocessor 204 reads a list of preset parameters-processed signals pre-stored in the memory 206, which is exemplified as a preset frequency value • a list of processed signals. The microprocessor 204 compares the frequency value with a pre-stored frequency value interval in the preset frequency value-processed signal list, and outputs a processed signal based on the comparison result. When the detected frequency value is in the preset frequency value interval, the earphone 1 is in the use state, and the audio frequency playing device 2 plays the audio. The use state of the earphone 1 means that the earphone 1 is worn in the ear of the user, and the user is using the The earphone 1 listens to the content played by the audio playback device 2; when the detected frequency value is not in the preset frequency value interval, the audio playback device 2 stops the audio playback. Similarly, when the sensor 102 is a pressure sensor or a capacitive sensor, the detection unit 203 corresponds to a pressure frequency converter or a capacitance frequency converter, and the principle of determining the state of use of the earphone is the same. No longer detailed. The headphone jack 202 includes a first pin 2021, a second bow 2022, a third pin 2023, and a fourth pin 2024 corresponding to the jack plugs 101 to 1014 of the guide 1. . The first pin 2〇21 is connected to the measuring pin 1011 of the earphone plug ιοί, the second bow 1 leg 2022 is connected to the audio ground pin 1012 of the earphone plug 101, and the second leg 2023 is connected to the earphone The left channel pin 1〇13 of the plug 101 is connected to the right channel pin 1〇14 of the earphone plug 1〇1, and the connection mode is as shown in FIG. 5. The memory 206 stores, in addition to the 11 200835380 'programs and instructions for running the audio playback device 2 and the preset parameter_processing signal list, a preset pause play time ΤχΟ. In the present embodiment, the preset pause time ΤχΟ can be set or corrected by operating the key unit 2〇1 of the audio playback device 2. For example, the preset pause time is set to 5 minutes, and if the audio playback device 2 pauses the playback time for 5 minutes when the timer 207 is counted, the audio playback device J 2 will be automatically turned off when it is detected that the earphone 1 is still in the non-use state. When the earphone 1 is connected to the earphone jack 2〇2 of the audio playback device 2, the first pin 2021 of the earphone jack 202 is electrically connected to the measurement pin 1011 of the earphone plug 101, and thus forms with the sensor 102. Electrical connection. The detecting unit 203 electrically connects the sensor 102 through the first pin 2021 on the earphone jack 202, and outputs a 〆 detection value (here, a frequency value) according to the temperature state of the sensor 102. The microprocessor 204 compares the detected frequency value with a frequency value interval ratio φ in the preset frequency value-processed signal list stored in the memory 2〇6, and determines whether the earphone 1 is in use according to the comparison result. status. When it is judged that the headphone 1 is in the use state, the microprocessor 204 outputs a processing signal to the audio playback unit 205, and controls the music playback unit 205 to continue playback. When it is judged that the headphone i is in the non-use state, the audio playback device 2 pauses playing the audio and starts the timeout period. When the earphone 1 is detected to be used again within the preset pause play time TxO, the audio playback device 2 continues to play the audio 'otherwise, the power of the audio playback device 2 is turned off. For example, the detecting unit 203 is electrically connected to the sensor 1〇2 through the measuring pin 1011 of the earphone plug ιοί, and outputs a detected frequency value according to the temperature state of the sensor 102 12 200835380, the micro The processor 204 compares the detected frequency value with the frequency value in the preset frequency value-processed signal list, and determines the use state of the earphone according to the comparison result. When the detected detection frequency value is not in the preset frequency value interval, the audio playback device 2 determines that the earphone 1 is in the non-use state, and the audio playback device 2 pauses the audio playback' timer 207 to start the timeout pause time Tx; In the range of time Tx0, when the microprocessor 204 immediately concludes that the detected frequency value is in the preset frequency value interval, the working state of the audio playback device 2 is changed from the pause playback state to the playback state. When the pause time Τχ reaches the preset pause time Τχ 0 and the frequency value is not detected to be in the preset frequency value interval, the power of the audio playback device 2 is turned off.

The sensory descent 102 includes a sensor; [〇2a and i〇2b, the subtractive cry 102a is distributed on the housing of the earphone body 10a, and the sensor 1〇2b is distributed in the earphone body 103b. On the housing, as shown in Figure 3. In this embodiment, the sensing port number 5 may be a human body temperature value, a pressure value, or a sensing capacitance value. The preset parameter_processing signal list may be a preset temperature value-processed signal list, a preset pressure value_processed signal list, or a Φ preset sensed capacitance value-processed signal list, depending on the type of sensing. For example, when the sensor 1〇2 is a temperature sensor, the corresponding sensing signal is a human body temperature value, and the preset parameter-processing signal list corresponds to a preset temperature value_processing signal list. When the user inserts the earphone 1 into the ear hole, the detecting unit 203 receives the human body temperature value output from the sensor 1〇2 and inputs a detected value (here, the received human body temperature value) to the microprocessor 204. The microprocessor 204 reads a preset temperature value-processed signal list pre-stored in the memory 206, and compares the temperature value with a pre-stored temperature value interval in the preset temperature value-processed signal list, and according to the comparison result A processing signal is output. When the detected temperature value is 14 200835380 in the preset temperature value interval, the audio playback device 2 plays the audio; when the detected temperature value is not in the preset temperature value interval, the audio playback device 2 pauses playing the audio and starts. Timeout time. The audio playback device 2 continues to play audio when the headset is detected for reuse within the preset pause time TxO, otherwise the power of the audio playback device 2 is turned off. Similarly, when the sensor 102 is a pressure sensor or an inductive capacitance sensor, the preset parameter-process signal list corresponds to a preset pressure value-process signal list or pre-sense capacitance value-processing The signal list is the same as the principle of determining the state of use of the headset i, and will not be described in detail here. In the above manner, the audio playback device 2 judges the use state of the earphone 1 to automatically control the operation of the audio playback device according to the use state of the earphone 1, thereby saving the power of the audio playback device 2.
