Bone conduction speaker module and bone conduction earphones having bone conduction speaker modules

Abstract

The present invention relates to a bone conduction speaker module and bone conduction earphones having bone conduction speaker modules and, more specifically, to a bone conduction speaker module and bone conduction earphones having bone conduction speaker modules, which can accurately output sound by minimizing the distortion of an inputted signal, can stably output sound with little vibrations, enable a user to use the earphones in a comfortable state by minimizing the vibrations transmitted to the user, prevent a strain from being put on the user's body even when the earphones are used for a long time, by minimizing the influence thereon, which a magnetic force of a magnet provided therein exerts on the user, facilitate the wearing thereof since the earphones are formed as an in-ear type, and can prevent an accident from occurring when the user does not hear an external sound, by allowing the user to naturally hear the external sound. To this end, the present invention relates to the bone conduction speaker module used for earphones, headphones and hearing aids, the bone conduction speaker module comprising: a housing comprising a first case for covering a part coming into contact with the human body, and a second case for covering the other side of the first case; a magnet part provided inside the housing; and a voice coil part positioned at the top of the magnet part.

Description

technical field [0001] The present invention relates to a bone conduction speaker module and a bone conduction earphone provided with the bone conduction speaker module, more specifically, to the following bone conduction speaker module and the bone conduction earphone provided with the bone conduction speaker module, that is, the The distortion of the signal is minimized to output accurate sound, and it can also output stable sound with less vibration, and minimize the vibration transmitted to the user, so that not only can it be used in a comfortable state, but also because the internal The magnetic force of the magnet minimizes the influence on the user, and prevents the burden on the human body even if it is used for a long time, and because it is formed in the ear, it is not only easy to wear, but also can hear external sounds naturally, so , It can prevent safety accidents caused by not being able to hear external sounds. Background technique [0002] Generally, there...

Problems solved by technology

[0013] However, the technology described in Korean Patent No. 10-0770590 has the advantage of playing sound through bone conduction, so that people who cannot hear sound through air conduction due to eardrum damage can hear sound stably. , but since the magnets installed inside are located close to the body, in order to increase the output of the speaker, the specifications of the magnets are increased and the number is increased, which will have a bad effect on the human body due to the strong magnetic force, and, due to the loudspeaker required Complicated structure of required parts, with problems of rising cost and noticeably low sound quality when playing sound

[0014] Moreover, compared to the conventional air conduction headphone, the volume and sound quality output by the above-mentioned bone conduction speaker are about 50% to 60% lower, so the reception rate is significantly lower in the external noisy environment. Thereby having a problem that it is difficult to receive sound clearly

[0015] And, as mentioned above, in the case of using another amplifier in order to compensate for the low output of the above-mentioned bone conduction speaker, there is a problem that, since the vibration according to the amplification becomes larger, the vibration is transmitted to the user, and because of the impact It is inconvenient to use, so the sound is transmitted to the outside, causing noise to the surroundings

[0016] In addition, in order to wear the existing bone conduction speaker on the head, another bracket with good elasticity is required, so there are problems such as the overall area becomes larger, it is difficult to store, and the wearing feeling is uncomfortable.
