The existing vibrators for bone conduction are generally placed inside a housing. The vibrator can vibrate the peripheral air to generate sound besides transmitting sound through bones, and the vibrator can generate echo in the shell when vibrating the air to generate sound, so that the sound quality effect is influenced.

For this reason, referring to fig. 1 and 2, a first aspect of the present invention provides a sound cavity structure, which includes: a housing 1 having a cavity therein; a vibrator 2 fixed inside the cavity; and the salient point 3 is arranged on one side of the cavity relative to the vibrator 2, and the salient point 3 is used for changing the transmission direction of the sound wave generated by the vibration of the vibrator 2 so as to weaken the intensity of the sound wave.

The utility model discloses in, in 2 vibration phonation of oscillator propagate the cavity with the sound, will reflect to all directions when the sound wave propagates to the surface of bump 3, the sound wave weakens gradually when the reflection, finally reaches the echo in people's the ear just seldom. From this, use this sound cavity structure can reduce the interference of echo, promoted the tone quality effect, experience better.

In the present embodiment, a plurality of the bumps 3 are provided, and the bumps 3 are uniformly arranged inside the cavity.
