Technical field
The utility model relates to audio frequency communication sphere, is specifically related to a kind of L-type vibrating reed and folded sound full range osteoacusis loudspeaker.
Background technology
Most of sound that we hear is because sound wave forms through air.Sound wave arrives cochlea inner ear by outer middle ear.Sound wave can also pass to cochlea by the direct vibration of skull.Earphone on market is all much to adopt loudspeaker to fill in human body ear or make earmuff type now, can cause like this: first easily damages the ear-drum of human body ear, second we while earphone directly being filled in to human body ear when using earphone, wear for a long time and can make hearing just greatly decline, the 3rd is the ear that cannot liberate us.Osteoacusis is that sound is passed to inner ear by skull, and bone nerve conduction oscillator is a kind of transducer, and directly conversion electron signal is mechanical signal.Bone nerve conduction oscillator is the new world standard of audio area on mobile device.It provides wideband voice accurately to export to user.Prepare to send at any time a novel audio frequency.The establishment of bone nerve conduction oscillator is transmitted sound rather than is applied pressure to your ambient air by vibration.It is very clear that audio signal transmits, so that the reaction of brain and synchronous sound.
People are more and more higher to the requirement of sound now, to the demand of sound, also each is different, someone wants high pitch brighter, someone wants bass heavy, and present osteoacusis is structure and material characteristic due to product substantially, cause cannot be smooth-going as the sound film of traditional loudspeaker, 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 improving is also more and more stronger.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, and a kind of L-type vibrating reed and folded sound full range osteoacusis loudspeaker are provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of L-type vibrating reed and folded sound full range osteoacusis loudspeaker, comprise magnetic circuit part, L-type vibrating reed combined mechanism and folded soundboard assembly, by the location notch of magnetic circuit part outermost, L-type vibrating reed combined mechanism is fixed to magnetic circuit part in the mode of laser spot welding, the last top that more folded soundboard is bonded in to vibrating reed combined mechanism.
The utility model also has some technical characterictics like this:
Described magnetic circuit part comprises U-shaped iron, magnet and washer, and there is individual holddown groove at UXing Tie center, and magnet is placed on to UXing Tie center, and washer is bonded on magnet, makes U-shaped iron, magnet and washer form the magnet of a loop circuit.
Described L-type vibrating reed combined mechanism comprises that voice coil loudspeaker voice coil, L-type vibrating reed, spacer are fixedly connected with frame with voice coil loudspeaker voice coil, the location notch that voice coil loudspeaker voice coil is fixedly connected with on frame by voice coil loudspeaker voice coil is fixed on center by voice coil loudspeaker voice coil with glue, by the centre bore on L-type vibrating reed, through voice coil loudspeaker voice coil, be fixedly connected with in the center column on frame, finally again the centre bore on spacer is fixedly connected with in the center column on frame through voice coil loudspeaker voice coil, with glue, L-type vibrating reed is fixedly clamped.
Described folded soundboard assembly comprises folded soundboard, and this folded soundboard is sounding board.
Described folded soundboard is bonding is that the centre bore of folded soundboard is positioned bonding in the newel of L-type resonance plate combined mechanism.
The utlity model has following useful effect:
The utility model is reasonable in design, adopt L-type design feature to make the arm of force elongated, effectively improve the sensitivity of sound and add large amplitude, make the bass of product more thick and heavy comfortable, by form and the frequency of the folded soundboard that resonates, sound again amplified and revised in addition, to reach, reducing the advantage that power consumption improves tonequality.
