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, its operation principle is different with traditional loudspeaker, is to realize sound by bone vibration
Sound conducts, and usual human ear is that the vibration of air is reached into ear-drum shake-up auricularis by external auditory meatus and sound is perceived, existing bone
Conduction technique is to be directly conducted to auricularis by human skull and perceive sound.The application time of bone conduction technology is not long,
It is urgently to be resolved hurrily that product still has many technical problems；In existing miniature bone-conduction speaker (loudspeaker), except piezoelectric ceramic vibrator
It is sub outer, nearly all it is made up of magnet, coil, oscillating plate and biography vibrating device, vibrational system is also nearly all made up of balance plate
Product layer structure, when bone-conduction speaker works, along with the vibration of oscillating plate, by the contact with skin bone will vibrate into
Row transmission.
Existing bone-conduction speaker has suspension type structure and outstanding support structure.The vibrational structure part of both structures is all
State in flying shore, when vibrational system axially moves, because the Q values of vibration system are relevant with the quality of vibration system
System, because there is error in the assembling of voice coil loudspeaker voice coil and magnetic system, under resonance dynamic frequency, the transient acceleration meeting of suspension type structural vibration system
What is become is very big, and vibration system can not smoothly axially move, and cause vibration frequency unstable, so as to abnormal sound occur, influences
Tonequality.When doing dropping shock experiment, because vibrational structure part is supported using thin elastic material, when being impacted easily
Deform upon, so as to influence the reliability of loudspeaker.When electric current flows through coil, according to electrified wire ampere suffered in magnetic field
Formula F=B*I*L of power understands that electric current is bigger, and Ampere force F is bigger, that is to say, that in the audio signal by one section of high current
When, vibration sense can be very strong, the skin bone of people is contacted for a long time, people can not feel well, and existing bone-conduction speaker
Interior is provided with a magnet, and its sensitivity is very low, using with inconvenience.
The content of the invention
Prior art is difficult to the need for meeting people, and in order to solve above-mentioned problem, the utility model proposes one
Bone-conduction speaker is planted, it greatly improves its spirit using double Magnet designs, vibrating plate using fine and close metal material making
Quick property, while also improving the high bass of bone-conduction speaker.
To achieve the above object, the utility model provides following technical scheme：A kind of bone-conduction speaker, including outside first
Shell, second housing, coil, the first magnet and the second magnet；First shell is fastened on second housing, and the first shell and
Cavity is formed between two shells；The coil, the first magnet and the second magnet are separately positioned in cavity；And coil and second
Shell is adjacent；The first metal cover board and the second metal cover board, and the first magnet and the second magnet are arranged with the coil respectively
It is separately mounted on the first metal cover board and the second metal cover board；Shake is provided between second magnet and the second metal cover board
Moving plate；First magnet and the second magnet upper end are fixedly connected by support.
Further, the vibrating plate is made using fine and close metal material.
Compared with prior art, the beneficial effects of the utility model are：The bone-conduction speaker, it is set using double magnet
Meter, vibrating plate is made using fine and close metal material, its sensitivity is greatly improved, while also improving bone-conduction speaker
High bass, be the Gospel of music-lover, but also can protect ear-drum, the spy such as protection hearing is injury-free and radiationless
Point, it is simple to operate practical, it is easy to promote the use of.
