Description
Technical field
The utility model is specifically related to a kind of full range osteoacusis loudspeaker.
Background technology
Most of sound that we hear is because sound wave is through air formation.Sound wave arrives cochlea inner ear by outer middle ear.Sound wave can also pass to cochlea by the direct vibration of skull.Now earphone is commercially all much adopt loudspeaker filled in human body ear or be made earmuff type, can cause like this: the ear-drum of the first easy damage human body ear, second we when when using earphone earphone directly being filled in human body ear, long-term wearing can make hearing just greatly decline, and the 3rd is the ear cannot liberating us.
Osteoacusis is that sound is passed to inner ear by skull, and bone nerve conduction oscillator is a kind of transducer, can conversion electron signal be directly mechanical signal.Bone nerve conduction oscillator is audio area new world standard on the mobile apparatus.It provides wideband voice accurately to export to user.Preparation at any time sends a novel audio frequency.The establishment of bone nerve conduction oscillator is by vibration passing sound instead of apply pressure to your ambient air.It is very clear that audio signal transmits, so that the reaction of brain and synchronous sound.
The requirement of people to sound is now more and more higher, also each different to the demand of sound, someone wants high pitch brighter, someone wants bass to sink, and present osteoacusis is that cause cannot be smooth-going as the sound film of conventional horn due to the structure and material characteristic of product substantially, common osteoacusis is that the general high frequency of the poor intermediate frequency of low frequency is better, and sensitivity is poor, cannot realize the more demand of people.So wish that the sound improved is also more and more stronger.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, provides a kind of full range osteoacusis loudspeaker.
The purpose of this utility model is achieved through the following technical solutions:
A kind of full range osteoacusis loudspeaker, comprise magnetic circuit unit, band resonance shell fragment housing unit and Voice coil assemblies, described magnetic circuit unit comprises U-shaped iron, magnet and washer, U-shaped iron, magnet and washer synthesize the magnet of a loop circuit, described band resonance shell fragment housing unit comprises resonance shell fragment, upper cover and plastic casing, described Voice coil assemblies comprises voice coil loudspeaker voice coil and voice coil loudspeaker voice coil fixed head, resonance shell fragment center is provided with location hole, magnetic circuit unit is fixed on resonance shell fragment in the mode of laser spot welding, bottom voice coil loudspeaker voice coil fixed head upwards, upper cover is positioned at voice coil loudspeaker voice coil fixed head bottom upper.
The utility model also has some technical characteristics like this:
UXing Tie center is provided with holddown groove, and magnet is placed in the holddown groove of UXing Tie center, and washer is bonded on magnet.
Voice coil loudspeaker voice coil fixed head is provided with location notch, and voice coil loudspeaker voice coil is placed in location notch, is located by voice coil loudspeaker voice coil, uses glue to be fixed.
Resonance shell fragment center is provided with location hole.
After Voice coil assemblies is bonding with plastic casing, Voice coil assemblies is placed in the location notch of the plastic casing of resonance shell fragment, is adhesively fixed by glue.
The utility model has effect useful as follows:
The utility model is reasonable in design, easy to use, adopts fan blade type resonance shell fragment arm of exerting all one's strength elongated, effectively improves the sensitivity of sound and adds large amplitude, and make the bass of product more thick and heavy comfortable, production efficiency is high in addition, and employing magnet is stronger by center magnetic force.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of full range osteoacusis loudspeaker, comprise magnetic circuit unit, band resonance shell fragment housing unit and Voice coil assemblies, described magnetic circuit unit comprises U-shaped iron 1, magnet 2 and washer 3, U-shaped iron 1, magnet 2 and washer 3 synthesize the magnet of a loop circuit, described band resonance shell fragment housing unit comprises resonance shell fragment 4, upper cover 5 and plastic casing 8, described Voice coil assemblies comprises voice coil loudspeaker voice coil 6 and voice coil loudspeaker voice coil fixed head 7, resonance shell fragment 4 center is provided with location hole, magnetic circuit unit is fixed on resonance shell fragment 4 in the mode of laser spot welding, bottom voice coil loudspeaker voice coil fixed head 7 upwards, upper cover 5 is positioned at voice coil loudspeaker voice coil fixed head 7 bottom upper, U-shaped iron 1 center is provided with holddown groove, magnet 2 is placed in the holddown groove of U-shaped iron 1 center, washer 3 is bonded on magnet 2, voice coil loudspeaker voice coil fixed head 7 is provided with location notch, voice coil loudspeaker voice coil 6 is placed in location notch, voice coil loudspeaker voice coil 6 is located, use glue is fixed, resonance shell fragment 4 center is provided with location hole, after Voice coil assemblies is bonding with plastic casing, Voice coil assemblies is placed in the location notch of the plastic casing of resonance shell fragment 4, be adhesively fixed by glue.
Operation principle: magnetic circuit part, magnetic circuit part is fixed in by reference column on the location hole of resonance shell fragment by resonance shell fragment plastic casing part and Voice coil assemblies three part, welded by the mode of laser spot welding, then voice coil loudspeaker voice coil fixed head is placed on (voice coil loudspeaker voice coil direction inwardly) in the bottom location notch of plastic casing, cements with glue; Because voice coil loudspeaker voice coil is positioned in the magnetic field of magnetic circuit part, when the electric current that audio signal produces is through voice coil loudspeaker voice coil, voice coil loudspeaker voice coil can produce transformable magnetic field because of the change of electric current, thus produce with the permanent-magnetic field that magnetic circuit part produces and interact, and vibration is produced, then by spacer, vibration signal is delivered on folded soundboard.Thus send the vibration of different frequency, the audio conversion of sound generator is changed into mechanical oscillation, is sent to auditory nervous system through human body bone and is reduced to sound.
Resonance shell fragment housing unit part is first placed in the middle of plastic mould by resonance shell fragment, is fixed in the middle of plastic casing, makes product more firm, finally cover upper cover by mould molding by resonance shell fragment.
Laser spot welding is connected to be divided with resonance shrapnel part by magnetic circuit part, and there is individual location hole at resonance shell fragment center, is placed by the reference column of magnetic circuit part and relocates in hole, then carry out spot welding with laser and fix, make it more firm.
