Bone conduction earphone

Abstract

The invention discloses a bone conduction earphone, parts of the bone conduction earphone comprise a plurality of metal material assemblies, and all or part of the metal material assemblies in the bone conduction earphone are made of amorphous alloy. Sound transmitted by the bone conduction earphone is better in quality. Compared with the conventional metal material, the amorphous alloy has relatively low elastic modulus and relatively high elastic limit; corresponding deformation of the tone quality of the earphone can be realized under the condition that relatively small force conduction isrequired; therefore, a wearer can obtain corresponding sound conduction; energy saving, the deformation amount realized in the amorphous alloy deformation process can conduct different tone quality effects; the amorphous alloy has stronger realization space in the aspect of tone quality, so that a wearer can obtain a better tone quality level by changing, and the sound effect and tone quality which can be obtained by other conventional materials such as a heavy bottom tone, a high pitch and the like through higher deformation force can be obtained by using an amorphous alloy of a specific system without changing the overall structural design.

Description

technical field [0001] The invention relates to a bone conduction earphone. 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, compression bone conduction (Compression Bone Conductio...

Problems solved by technology

However, in the actual use process, it is found that the anti-rust and anti-corrosion performance of steel materials is really average, especially the part of bone conduction earphones that contacts human skin during use (the environment that has been eroded by sweat and oil for a long time) is very easy to rust, and due to the density High and its own characteristics, it is difficult to satisfy the sound quality transmission, especially in order to pursue better sound quality, so that the parts such as the sound transmission vibration plate are designed to be longer and larger

When the vibrator vibrates, the vibrating plate transmits different amplitudes according to the frequency released by the vibrator. Due to the limitation of its own elastic limit and high elastic modulus, the steel material can only produce the required force when the vibrating plate needs to reach a large force. The amount of deformation, which makes the battery capacity and electronic control ability of bone conduction earphones need to be enhanced to achieve the expected sound quality, which increases energy consumption (higher sound quality requires a larger battery), and makes the weight of bone conduction earphones high No less, it not only increases the processing cost, but also makes the overall structure of bone conduction earphones bulky, which runs counter to the current trend of thin and light electronic products, and naturally cannot gain a foothold in the consumer market

[0009] Although iron and steel materials have very obvious shortcomings, because the comprehensive performance of the materials that may be used for replacement in the prior art is not as good as that of steel materials, especially when it comes to lightweight design, those skilled in the art consider the requirements of light and thin design , it will not be replaced by materials with a density higher than steel materials, and some materials with lower densities than steel materials (such as special plastics, magnesium alloys, aluminum alloys) cannot meet the requirements in terms of sound quality conduction, so steel materials are still The first choice for metal parts on bone conduction headphones
