Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Embodiment one

Referring to Fig. 1, Fig. 1 is a structural block diagram of a wireless earphone provided by an embodiment of the present invention, which is described in detail as follows:

The embodiment of the utility model is achieved in this way. A wireless earphone includes a switch, an antenna, a speaker, a microphone, and a battery for powering the antenna, the speaker, and the microphone. The wireless earphone also includes:

A bluetooth chip 100 connected to the antenna;

A touch chip 200 connected to the bluetooth chip 100;

The substrate 300 is connected with the touch chip 200 and is connected with the touch sensing component after being touched.

Wherein, the wireless headset further includes an indicator light connected to the Bluetooth chip 100 .

It works as follows:

After the substrate 300 is touched, it is connected to the touch sensing component, and outputs capacitance or inductance to the touch chip 200, so that the touch chip 200 outputs different touch signals to the Bluetooth chip 100 according to different capacitance or inductance values. control signal to realize functions such as selecting songs and controlling the volume.

For illustration, an example is as follows:

Touch the substrate 300 with a finger, the capacitance or inductance of the substrate 300 changes, the touch chip performs analysis and processing, and transmits the capacitance or inductance to the data decoder in the Bluetooth chip 100 through the I2C serial bus.

Wherein, the decoder analyzes the set gestures according to the software in the prior art, and realizes corresponding functions according to the corresponding gesture instructions.
