Problems solved by technology

[0003] In the existing bone conduction earphones, only one bone conduction receiver is usually installed, and the output audio frequency range is small, only 300-3000Hz, so it can only meet the needs of hearing speech or hearing the surrounding sounds, not listening to music or listening to music. higher quality requirements

Embodiment 1

[0029] Such as Figure 1-3 As shown, a multi-unit bone conduction earphone includes an elastic body 5 and two cuboid bone conduction receivers embedded in the cylindrical elastic body 5, and part of the surface of the bone conduction receiver protrudes from the elastic body 5; The elastic body 5 can be embedded in the auricle or ear hole, wherein the protruding part 11 of the bone conduction receiver protruding from the elastic body is in contact with the ear bone in the ear, and the connection mode between the bone conduction receiver and the elastic body 5 is as follows: Bonding, the elastic body 5 is made of rubber.

[0030] The bone conduction receiver includes a shielding shell 1, a diaphragm 2, a magnetic drive mechanism 3 and a power guide rod 4, wherein a part of the shielding shell 1 protrudes from the elastic body 5; the diaphragm 2 is fixed on the inner wall of the shielding shell 1 and protects the shielding The inner cavity of the shell 1 is airtightly separated;...

Embodiment 2

[0034] All the other are identical with embodiment 1, and difference is, as Figure 4 As shown, three rectangular parallelepiped bone conduction receivers are embedded in the cylindrical elastic body, and the three bone conduction receivers include a low-frequency bone conduction receiver 7, a middle-frequency bone conduction receiver 8 and a high-frequency bone conduction receiver. Receiver 9, three bone conduction receivers are evenly arranged on the elastic body, and the three bone conduction receivers are respectively connected with the frequency divider.

[0035] At the same time, there are three high, medium and low audio segment bone conduction receivers, and the frequency range of the output audio is between 100-12KHz. Compared with the double-unit bone conduction earphone in Embodiment 1, the bandwidth has been significantly improved. The improvement can fully meet the requirements of the user's dialogue quality, and the timbre is richer, so as to achieve a richer and...

Embodiment 3

[0037] All the other are identical with embodiment 2, and difference is, as Figure 5 As shown, the elastic body is a sponge in the shape of a sphere, and the bone conduction receiver is a sphere.

Abstract

A multi-unit bone conduction type earphone comprises an elastomer and at least two bone conduction type receivers embedded in the elastomer, and parts of the bone conduction type receivers protrude out of the elastomer. The elastomer is embedded in an ear, and the protruding portions of the bone conduction type receivers are connected with the otica in the ear in a contacting mode. The multi-unit bone conduction type earphone adopts the structure that multiple bone conduction type receivers of different audio segments are embedded in the elastomer, and the bone conduction type receivers are enabled to be more comfortable to wear. On the basis of meeting hearing needs of a user, the bandwidth and the frequency width of the voice output of the earphone are increased, and therefore the purpose of enabling listening feeling to be more abundant and gentle is achieved.

Description

technical field [0001] The invention relates to a bone conduction receiver, in particular to a multi-unit bone conduction earphone. Background technique [0002] Bone conduction earphones convert electrical signals into vibration signals, and make people hear sound through contact with the ossicles of the human body. The sound does not need to be transmitted through the air. , but have normal bone conduction hearing and other conductive hearing loss patients. Later, people found that when listening to sound with bone conduction earphones, since there is no air vibration, it will not affect the hearing function of the human ear, and it will not have any impact on the human eardrum. Use bone conduction headphones. However, for the bone conduction earphones used outside the ear, because the fixation is troublesome, the requirements for concealment and aesthetics cannot be met. [0003] In the existing bone conduction earphones, only one bone conduction receiver is usual...
