Bone conduction loudspeaker

Abstract

The invention relates to the technical field of horns, in particular to a bone conduction horn which comprises a supporting frame, a golden finger is arranged on the supporting frame, a sound bone transmission body is arranged in the supporting frame, a balancing weight is arranged on the sound bone transmission body, a magnetic conduction piece is connected into the sound bone transmission body in a sleeved mode, and a magnetic body is arranged on the side, facing the inner wall of the supporting frame, of the magnetic conduction piece. A magnetic conductive washer is arranged at the bottom of the magnetic body, a voice coil is arranged on the outer wall of the magnetic body, electric connecting pieces are arranged on the inner wall of the supporting frame, the electric connecting pieces are connected with the supporting frame in an embedded mode, one sides of the electric connecting pieces are attached to the voice coil, mounting holes corresponding to the electric connecting pieces are formed in the supporting frame, and the mounting holes penetrate through the inner wall and the outer wall of the supporting frame. A design structure of gold finger internal welding and a new technology of convenient welding are adopted, welding space utilization is reduced, stable product welding is ensured, production, manufacturing and assembling are facilitated, the process is simplified, production is facilitated, and small-size bone conduction, high power, low FO value and low vibration frequency point are achieved.

Description

technical field [0001] The present invention relates to the technical field of horns, and more particularly, to a bone conduction horn. Background technique [0002] The reason why people can hear sound is because the vibration in the air transmits the vibration to the eardrum through the external ear canal, and the vibration formed by the eardrum drives the human auditory nerve. Using this principle, the bone conduction speaker appeared. When the bone conduction speaker works, it is transmitted to the human auditory nerve through the human skin, subcutaneous tissue and bones, so that people can hear the sound. The bone conduction speaker is a new type of technology. There is great potential for development in the noisy environment outside. [0003] The design and process of bone conduction in the existing market are more complicated, and its structure mainly includes a vibrating sheet for sticking to the skin, a vibrating sheet for transmitting vibration, a magnetic cavity...
