Bone conduction device

Abstract

The invention discloses a bone conduction device. A metal material assembly in the bone conduction device is completely or partially an amorphous alloy, and the amorphous alloy is one or more of a zirconium-based amorphous alloy, a rare earth-based amorphous alloy, a copper-based amorphous alloy, a titanium-based amorphous alloy, an aluminum-based amorphous alloy and a magnesium-based amorphous alloy. According to the device, the sound quality transmitted by the bone conduction device is better. The deformation amount realized in the amorphous alloy deformation process can conduct different tone quality effects. The device has stronger realization space in the aspect of sound quality, so that a wearer can obtain better sound quality level by changing, and the sound effect and the sound quality which can be obtained by other conventional materials such as heavy background sound, high pitch and the like through higher deformation force can be obtained by using amorphous alloy of a specific system without changing the overall structural design.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a bone conduction device. Background technique [0002] The auditory system is an important sensory organ for human beings to receive external signals. Under normal circumstances, the sound wave generated by the vibration of the sound source is transmitted to the inner ear through two channels: one is transmitted to the inner ear through the external auditory canal, the tympanic membrane and the ossicle chain composed of three ossicles, that is, the air conduction of the sound wave. It is the main conduction path of normal hearing; the second is to transmit directly to the inner ear through the skull, that is, bone conduction, which has little effect under normal physiological conditions. [0003] The main way of bone conduction to transmit sound is that the sound passes through the skull to vibrate the cochlea wall. There are two main conduction modes: [0004] First, ...

Problems solved by technology

[0007] Since the civilian use of bone conduction technology has not been promoted on a large scale, the existing bone conduction devices on the market often stay at the stage of "usable", that is, they can be guaranteed to be used. Research and development, but the technology that can be commercially transformed is mainly focused on the structural design of bone conduction devices and the development of new products, and there has been no leapfrog development

Commonly used materials in bone conduction devices are general-purpose materials such as rubber, plastic, conventional metal materials, or other composite materials. The performance of the above-mentioned general-purpose materials is limited, and it is difficult to produce excellent acoustic effects when applied to bone conduction devices. The acoustic effect is far from other existing devices, especially in the sound transmitted by the bone conduction device, the more saturated frequency band is missing, resulting in monotonous sound, poor use effect, and it is difficult to hit the higher-end sound generator market. The defects cannot be improved by the method of structural design
