Problems solved by technology

[0005] At present, many types of bone conduction speakers have been developed or are being developed. Almost all bone conduction speakers are composed of vibration resonators, magnets, coils and vibration components, and almost all vibration components are composed of multiple balanced The laminated structure formed by the plates, and because the current passed through the above coil has a critical value, there is a problem of low vibration efficiency as a whole
Low vibration efficiency, which is a major obstacle to improving speaker performance

Embodiment Construction

[0017] Fig. 1 is an exploded oblique view of the bone conduction speaker of the present invention, Fig. 2 is a cross-sectional view of the whole assembly, Fig. 3 is a cross-sectional action diagram, and Fig. 4 is an oblique view of assembly.

[0018] As shown in the figure, the bone conduction loudspeaker 100 made according to the present invention is composed of a frame container 110, a vibration resonator 120, a magnet 130, a balance plate 140, a coil 150, an upper and lower vibrating part 160, an upper and lower film pair 170, a vibrating ring 180 and Buffer ring 190 constitutes.

[0019] The frame container 110 is a bottomed cylindrical box part with an upper opening, usually made of plastic or equivalent materials, and there is no special requirement for the material.

[0020] In the frame container 110, a cylindrical vibration resonator 120 having the same bottom as the frame container 110 is inserted. In order to allow the electric wires or coil wires of the coil 150 to...

Abstract

The present invention relates to a technique and method for manufacturing a bone conduction speaker device by improving the vibration efficiency of a vibrating part caused by a magnet and a coil, and greatly improving speaker performance. Whole device is constituted as follows: the frame container 110 of top opening, the magnet 130 that frame container 110 interior places and the coil 150 around it, the vibrating part pair 160 that is combined with the coil 150 top and is spaced apart from each other at a certain distance, and in this pair of vibrating part 160 A pair of laminated thin films 170 arranged between them, and a vibrating ring 180 sandwiched between the thin films 170 convert the vibration generated from the coil 150 into sound and amplify it.

Description

technical field [0001] The invention relates to a manufacturing technology and method of a bone conduction speaker device, and its detailed content is to improve the vibration efficiency of the vibrating parts caused by magnets and coils in the bone conduction speaker, thereby greatly improving the performance of the speaker. Background technique [0002] Usually sound is transmitted by air conduction, and the vibration of the sound is transmitted to the tympanic membrane in the ear. There are three ear ossicles in the ear, and the sound is transmitted to the cochlea through the vibration of the periosteum through the ear ossicles. The cochlea is filled with lymph fluid, and the vibration of lymph fluid reaches the auditory nerve in the process of being converted into electrical signals. The human brain can recognize sounds in the above-mentioned way. [0003] The so-called bone conduction is to omit the process of vibration passing through the periosteum and ear ossicles ...
