Further, the vibration assembly 131 may further include a bracket, and the bracket is provided with a plurality of mounting holes. The plurality of mounting holes, to which the vibration mechanism 1311 is mounted, may be arranged linearly or in an array. The extending direction of the mounting hole can be parallel to the moving direction of the vibration mechanism 1311, and the mounting hole can be used for restricting the movement of the vibration mechanism 1311 and preventing the vibration mechanism 1311 from deviating from a preset track when moving.

Different from the air conduction path, the medium for transmitting sound/vibration in the bone conduction path is a solid or a solid-liquid mixture, and the characteristics of the transmission path have obvious influence on the bone conduction tone quality. The skin and subcutaneous soft tissue have greater mechanical damping, and the transmission efficiency of the skin and subcutaneous soft tissue to high-frequency sound/vibration is lower, so that the high frequency of bone conduction sound is weakened or lost; the hard bone on the transmission path has greater rigidity and is less efficient in transmitting low frequency sounds/vibrations, making the low frequency of bone conducted sounds weaker or absent. The control circuit may thus control the supply of the sound signal to the vibration mechanism 1311 in accordance with the frequency of the sound to be transmitted. For example, when the sound frequency is within a first predetermined range, part of the vibration mechanism 1311 receives the sound signal; when the sound frequency is outside the first preset range, all of the vibration mechanisms 1311 receive the sounding signal.

For example, when the switching unit is a transistor, a first terminal of the transistor is connected to the signal generator, a second terminal of the transistor is connected to the vibration mechanism 1311, and a control terminal of the transistor is connected to the control signal. The control signal is generated according to the frequency of the sound to be transmitted, and the on-off state of each transistor is controlled by the control signal. The control end of each transistor can be a grid electrode, the first end can be a source electrode, and the second end can be a drain electrode; alternatively, the control terminal of each transistor may be a gate, the first terminal may be a drain, and the second terminal may be a source. Further, each transistor may be an enhancement transistor or a depletion transistor, which is not particularly limited in this exemplary embodiment.

The vibration mechanism 1311 may include a bone conduction speaker, which may be at least one of an electromagnetic speaker, a piezoelectric speaker, and an electrostatic speaker. Specifically, the electromagnetic speaker may be a moving coil speaker, a moving iron speaker, or the like.
