Abstract
A kind of bone-conduction speaker, including the first shell, second housing, u-bracket, magnet piece, metal clips, magnet cover board and coil；It is formed with cavity between first shell and second housing；The coil is fixed on the first shell, and the metal clips is clipped between the first shell and second housing, and the u-bracket is fixed on metal clips, and the magnet piece is fixed among u-bracket, and the magnet cover board is fixed on another planar ends of magnet piece.The bone-conduction speaker, it is designed using u-bracket, and u-bracket has good magnetic conduction and gear magnetic action, metal clips to be made of fine and close metal material, greatly improves its sensitivity and durability.The utility model simple structure, reduces production cost, improves production efficiency, the high bass that bone passes bar loud speaker is improved, service life is extended, eliminates osteoacusis loudspeaker because shaking the sense of discomfort brought to user, it is the Gospel of music-lover, it is highly practical.
Description
Technical field
The utility model is related to loudspeaker apparatus technical field, specially a kind of bone-conduction speaker.
Background technology
Existing bone-conduction speaker, operation principle is different with traditional loud speaker, is to realize sound by bone vibration
Sound conducts.Usual human ear is to reach the vibration of air by ear-drum touches auricularis by external auditory canal to perceive sound, existing bone
Conduction technique is to be directly conducted to auricularis by human skull by perceive sound.The application time of bone conduction technology is not grown,
It is urgently to be resolved hurrily that product still has many technical problems；In existing miniature bone-conduction speaker (loud speaker), piezoelectric ceramic vibrator is removed
It is sub outer, it is nearly all made of magnet, coil, oscillating plate and biography vibrating device, vibrational system is also nearly all made of balance plate
Product layer structure, osteoacusis is a kind of sound conduction mode, i.e., converts sound to the mechanical oscillation of different frequency, pass through people's
Skull, osseous labyrinth, the transmission of inner ear lymph, spiral organ, auditory nerve, auditory center transmit sound wave, bone-conduction speaker work
When, along with the vibration of oscillating plate, by transmitting vibration with the contact of skin bone, the skin bone of people is contacted for a long time
Bone, people can not feel well, and use be easy to cause the damage to ear-drum to the earphone that special bone-conduction speaker makes for a long time,
Hearing damage, sensitivity is very low, using with inconvenience.
Utility model content
Shortcoming present in view of the above technology, the utility model provide a kind of simple in structure, easy to operate, sound quality
Bone-conduction speaker good, with small vibration, leakage sound is small.
In order to achieve the above object, a kind of bone-conduction speaker of the utility model, including the first shell, it is second housing, U-shaped
Holder, magnet piece, metal clips, magnet cover board and coil；It is formed with cavity between first shell and second housing；
The coil is fixed on the first shell, and the metal clips is clipped between the first shell and second housing, and the u-bracket is solid
It is scheduled on metal clips, the magnet piece is fixed among u-bracket, and the magnet cover board is fixed on another plane of magnet piece
End, the second housing and the first shell are the extremely strong dense material of leading note effect sensitivity.
Wherein, the u-bracket is U-shaped magnetic conduction and gear magnetic holder, and the u-bracket is arranged outside the first shell and second
It is formed between cavity between shell.
Wherein, metal clips is the intermediate annular sheet metal for carrying through-hole, and the metal clips is fixed to be connected with U type holders
It connects.
Wherein, the coil be fixed on the first shell and with the first cage connection.
The utility model has the beneficial effects that：
Compared with prior art, the utility model bone-conduction speaker passes through the first shell, second housing, coil, magnet
Combination between cover board, metal clips, u-bracket and magnet piece, greatly improves its sensitivity and durability passes through bone
Bone transmits sound, reduces leakage sound, is effectively protected ear-drum, protects hearing, do not hinder ear-drum, the ear of long periods of wear bone-conduction speaker
Machine can improve one's hearing.The utility model simple structure, reduces production cost, improves production efficiency, improves osteoacusis
Senior middle school's bass of loud speaker, extends service life, reduces osteoacusis loudspeaker because shaking the sense of discomfort brought to user, is
The Gospel of music-lover, highly practical, use easy to spread.

Specific implementation mode
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
Refering to fig. 1, a kind of bone-conduction speaker of the utility model, including the first shell 10, second housing 11, u-bracket
15, magnet piece 12, metal clips 16, magnet cover board 13 and coil 14；Shape between first shell 10 and second housing 11
At there is cavity；The coil 14 is fixed on the first shell 10, and the metal clips 16 is clipped in the first shell 10 and second housing
Between 11, the u-bracket 15 is fixed on metal clips 16, and the magnet piece 12 is fixed among u-bracket 15, the magnetic
Iron covering plate 13 is fixed on 12 another planar ends of magnet piece, and the second housing is that leading note effect sensitivity is extremely strong with the first shell
Dense material.
Compared with prior art, the utility model bone-conduction speaker passes through the first shell 10, second housing 11, coil
14, the combination between magnet cover board 13, metal clips 16, u-bracket 15 and magnet piece 12, it is sensitive to greatly improve its
Property and durability sound is transmitted by bone, reduce leakage sound, be effectively protected ear-drum, protect hearing, do not hinder ear-drum, long periods of wear
The earphone of bone-conduction speaker can improve one's hearing.The utility model simple structure, reduces production cost, improves production effect
Rate improves senior middle school's bass of bone-conduction speaker, extends service life, reduces osteoacusis loudspeaker because shaking to user
