Bone conduction loudspeaker

Abstract

The present invention discloses a bone conduction loudspeaker which comprises a conduction shell, a sound control sheet arranged at one end of the conduction shell and contacted with the conduction shell and an accommodating space formed by the conduction shell and the sound control sheet in an enclosing mode, a coil and a magnetic assembly used for generating a magnetic field are accommodated inthe accommodating space, and the magnetic assembly, the conduction shell and the sound control sheet form a magnetic loop. The conduction shell and the sound control sheet are respectively made of electroacoustic materials with different thicknesses. The magnetic assembly, the conduction shell and the sound control sheet form a magnetic loop to form a magnetic system, the coil generates an alternating magnetic field after being electrified, and the alternating magnetic field enables the magnetic field intensity of the magnetic system to change, so that the sound control piece and the conduction shell vibrate, and people can sense sound through bone conduction; and the conduction shell and the sound control sheet are respectively made of materials with different thicknesses, mixing of different high pitches, alto pitches and / or low pitches can be achieved by means of the relation between the vibration frequency of an object and sounds, and the requirements of users for sounds of different frequency bands can be met.

Description

Technical field[0001]The present invention relates to the field of acoustic conversion, and more particularly to a bone conductor speaker.Background technique[0002]Bone conduction is a sound conduction method, so that the sound is converted into mechanical vibrations of different frequencies, passed through human skull, bone, inner ear oculum, spiral, listening to nerve, auditory hub, and generates acoustic waves with respect to the diaphragm The classic sound conduction method, bone conduction saves the steps of many acoustic wave delivery, can achieve a clear voice restore in a noisy environment, and the sound waves will not affect others because of the spread of the air.[0003]The bone conductor is a new type of electroacoustic conversion device developed based on bone conduction sound conduction method, which converts the electrical signal into mechanical vibration signal, and passes the vibration signal through the human tissue and the bone into the cochlea, He heard the sound, ...

AI Technical Summary

Problems solved by technology

However, the sound transmitted by the existing bone conduction vibration speakers is mostly low-frequency sound, and the frequency of the transmitted sound is single, which cannot satisfy users' pursuit of other sounds in different frequency bands.
