Description
Technical field
The utility model relates to the loudspeaker techniques field, particularly a kind of loudspeaker voice coil and locating branch slice thereof.
Background technology
Along with development of electronic technology, the various kinds of equipment miniaturization has been irreversible trend, and the miniaturization of equipment is more and more higher to the requirement of loudspeaker design simultaneously.The performance that how to improve loud speaker when loud speaker thickness, width all are restricted has become the biggest problem of numerous technical staff.
Existing loudspeaker design technology is often taked tone-off delineation position Design of device when not having space placement positioning device, bring the restriction on a lot of performances thus, makes the loud speaker that designs can not reach the requirement of some application.Particularly in the super narrow speaker design of overlength, this type of loud speaker is usually used in LCD TV, require highly sensitive, bass good, it is big to bear power, traditional design often adopts the design of multipath magnetic circuit multitone ring even many cones, this method for designing has following shortcoming:
(1) can not use big magnet, sensitivity is relatively low; (2) use a plurality of little voice coil loudspeaker voice coil efficient not high; (3) resonance frequency is higher relatively, and bass is bad.
In addition, because loud speaker mainly partly is made of oscillating component and magnetic circuit,, will consider following problem in overlength, super narrow, ultra-thin loudspeaker design:
(1) for the magnetic circuit part of loud speaker, if for obtaining better bass effect, magnet must be big as much as possible, and magnet needs big voice coil loudspeaker voice coil to cooperate greatly, uses and use big voice coil loudspeaker voice coil often to limit traditional positioner.(2) in order to obtain better bass effect, need to use the compound boundary cone, this cone is deformation easily radially, thereby can not limit the radial motion of voice coil loudspeaker voice coil well.(3) for the oscillating component of loud speaker, if use the runway shape voice coil loudspeaker voice coil of overlength and do not use locating branch slice, voice coil loudspeaker voice coil just deforms easily.(4) for ultrathin loudspeaker, if do not use locating branch slice, because voice coil loudspeaker voice coil can not obtain spacing in motion process or the location, its axial movement is difficult to obtain restriction, voice coil loudspeaker voice coil clashes into the bottom easily in axial running, simultaneously radially rock also easier generation, thereby cause bump magnet, pole piece or magnetic cover, unusual sound appears.
Can draw according to above-mentioned, for the magnetic circuit part of overlength, super narrow, ultra-thin loud speaker for oscillating component, if use the voice coil loudspeaker voice coil of overlength and big magnet to reach the performance that needs, just there is not the traditional positioner of space mounting in the voice coil loudspeaker voice coil outside, cause the voice effect of loud speaker can be subjected to respective limits, also can not get the spacing consequence that unusual pronunciation occurs that causes because of voice coil loudspeaker voice coil.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides and a kind ofly can limit the axial movement of voice coil loudspeaker voice coil and the locating branch slice that radially wobbles.
The technical scheme that realizes the utility model purpose is as follows:
The locating branch slice of loudspeaker voice coil, this locating branch slice comprise a plurality of suspension arms and outer ring and inner ring, and an end of suspension arm is connected with the outer ring, and the other end of suspension arm is connected with inner ring.
Adopted such scheme,, prevented the voice coil loudspeaker voice coil distortion owing to, its profile has been had a restriction with the bonding voice coil loudspeaker voice coil inside that is installed in of locating branch slice.Voice coil loudspeaker voice coil by the effect of locating branch slice and support, can limit the axial movement of voice coil loudspeaker voice coil and the radial motion of restriction voice coil loudspeaker voice coil when work.Locating branch slice is installed in voice coil loudspeaker voice coil inside, does not take the assembly space of parts such as other magnet, when using the voice coil loudspeaker voice coil of overlength, the width of voice coil loudspeaker voice coil also can be amplified to the size of maximum possible substantially, therefore, can use big as far as possible magnet.Be beneficial to the performance that improves vibrating mass and loud speaker.
Vibrating mass of the present invention can use overlength runway shape voice coil loudspeaker voice coil, vibrating mass of the present invention and magnetic circuit partly constitute loud speaker, and then can use big as far as possible magnet and big as far as possible integrated compound boundary cone, thereby fully improve the magnetic circuit utilization ratio and improve sensitivity, for the lower resonance frequency of arrival, the higher power that bears have been created possibility.Finally reach height and bear power, low resonant frequency, highly sensitive requirement.
For ultra-thin woofer, use vibrating mass of the present invention to reach height and bear power, low resonant frequency, highly sensitive requirement with littler bore and volume.
