The processing module 30, the light detecting module 40' that emits a second determining signal, and the power saving determining unit 50 connected to the audio processing module, the wire measuring module 40, and the power supply unit 20. The audio processing module is connected to the audio transmitting unit 80 and electrically connected to the source supply unit 20, and the audio processing module receives the audio data of the audio transmitting unit 8G. In this embodiment, The wireless headset 1G is used as a description of the preferred embodiment. Therefore, the audio transmitting unit 8G and the audio processing module are wirelessly connected and connected in a 1-wire manner from the Bluetooth, infrared, and wireless. The network form number A0101 page 5 / page 16 0992053086 - 201212663 group. Further, the audio processing module 30 has an audio receiving unit 31 and an audio releasing unit 32 connected to the audio receiving unit 31. The audio receiving unit 31 receives the audio data, and the audio releasing unit 32 transmits the audio information. The data is converted into a sound wave data and released into the air, and when the audio receiving unit 31 does not receive the audio data, the first determining signal is sent, indicating that the data is continuously imported, and is in a non-use state. The light detecting module 40 is electrically connected to the power supply unit 20, and includes a light emitting unit 41 and a pair of light receiving units 42 of the light emitting unit 41. The light emitting unit 41 emits a detecting light. The light receiving unit 42 is configured to receive the detected light, wherein the detecting light of the embodiment is an infrared ray, the light receiving unit 42 receives the infrared ray, and when the infrared ray is not blocked, indicating that the detected light is not in use In the state, the second section of the signal is sent. The power saving determining unit 50 receives the first determining signal and the second determining signal, and determines the audio processing module 30 and the light detecting module 40 by using the first determining signal and the second determining signal. In the use condition, when it is judged that no one is using, a sleep signal is sent to the power supply unit 20 to cause the power supply unit 20 to enter a power saving state. Here, the power saving determining unit 50 is connected to the audio processing module 30 and the light detecting module 40 by means of a connection. [0012] Please refer to FIG. 2, which is a schematic diagram of the appearance of a preferred embodiment of the present invention.

The light receiving unit 42 in the module 40 receives the detected light, indicating that no object is blocked between the two covers 11, that is, no one is used. [0013] In the embodiment, the audio processing module 30 sends the first determination signal only when the audio data of the audio transmitting unit 80 is not received. The light receiving unit 42 sends the second determining signal only after receiving the detecting light. The power saving determining unit 50 receives the first determining signal and the second determining signal in the same time period, and then confirms that there is no audio. The data is transmitted, and the light receiving unit 42 can receive the detected light, and judge that the wireless headset 10 is not used, and sends the sleep signal to the power supply unit 20, so that the power supply unit 20 enters the power saving state. It should be specially noted that the power saving state refers to a generally called power saving mode, or enters a sleep state, reduces the supply of power, and avoids waste of power in the power supply unit 20. In addition, in the above embodiment, the audio receiving unit 31 does not receive the signal, and the light receiving unit 42 sends the first determining signal and the second determining signal when receiving the detected light, but in actual application, Setting the transmission condition and time point of the first determination signal and the second determination signal according to different design conditions, or continuously transmitting the first determination signal and the second determination signal, but the first determination signal and the second The electronic signal representing the different usage conditions is entrained in the judgment signal. Furthermore, the power saving determining unit 50 determines whether to issue the sleep signal by using the first determining signal and the second determining signal, and is also 099130268 Form No. 1010101 Page 7 / Total 16 Page 0992053086-0 [0014] 201212663 The sleep signal may be issued by the first determination signal directly after the transmission of the audio data, so that the power supply unit 20 enters a power saving state. Or the power saving determining unit 50 directly determines, by the second determining signal, that the light receiving unit 42 in the light detecting module 40 receives the detecting light, indicating that no object is blocked between the two covers 11 The sleep signal is sent to the power supply unit 20, and the power supply unit 20 is put into a power-saving state, and different judgment levels are determined by different design modes.
