Referring to Figures 2 to 5, this creation provides a bone conduction speaker with a wearing detection function, including: a bone conduction speaker body 11, a conductive layer 2, a protective rubber cover 3, a capacitive sensor 4, and a controller 5. .

The conductive layer 2 is laid on the bone conduction speaker body 11.

In this specific embodiment, the bone conduction speaker body 11 includes a housing 111, an energy conversion device 112 and a vibration plate 113.

The protective rubber sleeve 3 is sleeved on the outside of the housing 111.

The energy conversion device 112 is a component that can convert electrical signals to mechanical vibrations. The vibrating plate 113 is fixedly connected to the energy conversion device 112 and is driven by the energy conversion device 112 to vibrate synchronously. The vibrating plate 113 protrudes from the open end of the housing 111 and fits the human skin 6, and the vibration is transmitted to the auditory nerve through the human tissue and bones, so that people can hear the sound.

The capacitive sensor 4 is connected to the conductive layer 2. Preferably, the capacitive sensor 4 is electrically connected to the conductive layer 2. The capacitive sensor 4 is used to collect the real-time capacitance value of the conductive layer 2.

There is an inductive capacitance between any two conductive objects. When the human skin 6 is close to the conductive layer 2, the human skin 6 and the conductive layer 2 jointly constitute the two poles of the inductive capacitance. When the skin is close to the conductive layer 2, the total induced capacitance value will increase. The capacitive sensor 4 senses the change in the induced capacitance value and outputs the changed real-time capacitance value.

The judgment module 51 is provided with a preset capacitance threshold. When the real-time capacitance value is within the range of the preset capacitance threshold, the judgment module 51 judges that the bone conduction earphone is in the wearing state; when the real-time capacitance value is lower than the preset capacitance threshold, the judgment module 51 judges that the bone conduction earphone is not in use.
