Bone-conduction headset device with single magnet and processing method thereof

Abstract

The invention discloses a bone-conduction headset device with a single magnet and a processing method thereof. The device comprises a vibration system consisting of a vibration transmitting sheet and a vibration plate, wherein a voice coil is fixedly arranged on the vibration plate; an outer magnetic conduction plate is further arranged; a magnet is arranged on the outer magnetic conduction plate; an inner magnetic conduction plate is arranged on the magnet; a gap is formed between the inner magnetic conduction plate and the outer magnetic conduction plate; and the voice coil is arranged in the gap. According to the bone-conduction headset device with the single magnet and the processing method thereof, the single magnet and the outer magnetic conduction plate which is arranged integrally are adopted, so that the structure of a product is simplified, a processing method for assembling the magnet without magnetizing during processing and magnetizing the magnet after assembling can be realized, the production efficiency is increased, and the product yield is increased.

Description

technical field [0001] The invention relates to a bone conduction earphone device and a processing method thereof, in particular to a single magnet bone conduction earphone device and a processing method thereof. Background technique [0002] In the prior art, bone conduction earphones are usually used in special applications, such as police or military communication equipment, but with the gradual development of technology, they are currently being extended to civilian applications. Because its conduction method is through bone vibration, bone conduction earphones have strong resistance to noise interference, so they are especially suitable for use in noisy outdoor environments. For civilian technology, the use of earphones usually needs to take into account sound quality issues. Therefore, the current bone conduction earphones have not made a good breakthrough in this direction (police or military bone conduction earphones do not need a wide frequency response to Enhance ...

AI Technical Summary

Problems solved by technology

[0007] The bone conduction earphones in the prior art adopt the double magnet structure of the ring magnet 22 and the inner magnet 23. Since the bone conduction earphone needs to increase the sensitivity of the loudspeaker, a stronger magnetic magnet must be used. Assembled on the bottom plate 24, but due to its magnetic properties, it is extremely difficult to assemble the product. During the assembly process, the ring magnet 22 and the inner magnet 23 are likely to be attracted to each other, causing the magnet assembly to deviate from the designed position, making it difficult to guarantee product quality, or due to excessive attraction. cause the magnet to break

However, since the ring magnet 22 and the inner magnet 23 require opposite magnetic polarities, they cannot be processed by first assembling and then magnetizing.
