In the present embodiment, the in-ear detection device 60 may include an LDS (Laser Direct Structuring) detection component, but may also be other in-ear detection devices 60, such as an infrared detection component.

In the using process, when the in-ear detection device 60 contacts with a human body, an in-ear detection signal is generated, the main control component 20 performs signal processing on the received in-ear detection signal and outputs a corresponding working control signal to control the wireless earphone to be in a wearing state after the in-ear state is detected, so that the main earphone and the slave earphone can be independently controlled to perform common functions such as song cutting, music playing and pause or connection and disconnection of a telephone.

When the in-ear detection device 60 is not in contact with a human body, an in-ear detection signal is not generated, and the main control component 20 outputs a corresponding standby control signal because the in-ear detection signal is not received, so as to control the wireless headset to be in an unworn state after detecting a non-in-ear state, so that the purpose of enabling the wireless headset to enter a low power consumption mode can be achieved through a state of suspending communication/music.

The setting position of the in-ear detection device 60 needs to be determined according to the shape of the wireless headset, and in order to improve the accuracy of in-ear detection, the in-ear detection device 60 is generally set at a position in the wireless headset, which is easily contacted with the human ear, and the number of the in-ear detection devices 60 may be 1, or 2, 3 or more, and is specifically determined according to the actual situation, which is not described herein.

The utility model also provides a wireless communication system, which comprises an external terminal and the wireless earphone; the external terminal is in wireless connection with the wireless earphone. The specific structure of the wireless headset refers to the above embodiments, and since the wireless communication system adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
