Abstract
The utility model relates to a voice coil, in particular to a frame shape of the voice coil. The voice coil comprises a frame and a coil wound outside the frame. The cross-sectional shape of the frame is like a race track, namely the middle of the cross section of the voice coil has two parallel line segments, two end points on the same side of the two parallel line segments are connected with two end points of an externally protruded arc, and the two end points on the other side of the two parallel line segments are connected with two end points of another externally protruded arc. The two arcs have the same radius, are symmetrical, and are 180-degree arcs or minor arcs. Compared with a round voice coil, the voice coil has the advantages that the volume of the voice coil is obviously reduced and the occupied space is reduced; due to the small volume, heat dissipation is fast, which is favorable for prolonging the service life of the voice coil; in addition, when electrified to work, the voice coil has shorter sound wave transmission distance than the round voice coil, so that the sound quality of a speaker is better; and from the acoustic angle, the sound waves of the race track type voice coil difficultly return back, so that the sound quality of the speaker of the voice coil is purer.
Description
Technical field
The utility model relates to a kind of voice coil loudspeaker voice coil, and particularly a kind of voice coil loudspeaker voice coil that is used for electronic products such as ultra-thin notebook computer and ultra-thin special loudspeaker is specifically related to the shape of the skeleton of this voice coil loudspeaker voice coil.
Background technology
Voice coil loudspeaker voice coil is the vibrating mass of loudspeaker; When the alternation tone currents passes through voice coil loudspeaker voice coil; Voice coil loudspeaker voice coil produces the magnetic field that changes with tone currents; The magnetic field that changes takes place to inhale mutually or repelling each other effect with the magnetic field of loudspeaker magnet, vibrates thereby cause voice coil loudspeaker voice coil to produce mechanical oscillation drive cone, promotes air repeatedly and sounds.
Voice coil loudspeaker voice coil is the important component part of dynamic speaker vibrational system, can be described as the heart of loud speaker.The performance of voice coil loudspeaker voice coil can influence the sound pressure frequency characteristic of loud speaker, sound pressure level, and impedance and impedance curve, distortion, transient response, the parameter of loud speaker, tonequality etc. are concerning the power and the life-span of loud speaker.
Voice coil loudspeaker voice coil mainly is made up of skeleton (bobbin, BOBIBN) and coil two parts of being centered around the outer lead coiling of skeleton, and speech coil framework plays support coil.The shape of tradition speech coil framework all is circular (referring to Fig. 1), and the volume that circular voice coil loudspeaker voice coil takies is bigger, and transmission sound wave distance is longer during product energising operation, and tonequality is relatively poor; In addition, from the angle of acoustics, circular voice coil loudspeaker voice coil lets sound wave turn round easily, makes loudspeaker tonequality muddy.
The utility model content
The utility model technical problem to be solved provides a kind of new-type voice coil loudspeaker voice coil of racetrack, and it is little to have a volume of taking, and tonequality is good, advantages such as rapid heat dissipation.
The utility model technical problem to be solved is achieved through following technical scheme:
A kind of voice coil loudspeaker voice coil; Comprise the coil that skeleton is outer with being centered around skeleton, the shape of cross section of speech coil framework is a racetrack, and promptly voice coil loudspeaker voice coil cross section middle part is two parallel segments; Two end points of these two parallel segment the same sides connect two end points of the circular arc of an evagination; Article two, two of the parallel segment opposite side end points also connect two end points of the circular arc of an evagination, and said two arc radius are identical and symmetrical, are 180 ° of circular arcs or minor arc (less than 180 ° circular arc).
Preferably, the length of the strong point of this racetrack voice coil loudspeaker voice coil is 22.92mm, and the width of the widest part is 9.1mm, highly is 12.5mm.
Preferably, the length of the strong point of this racetrack voice coil loudspeaker voice coil is 18mm, and the width of the widest part is 8mm, highly is 16mm.
The utlity model has following beneficial effect:
(1) the utility model volume obviously reduces with respect to the volume of circular voice coil loudspeaker voice coil, and minimizing takes up room.
(2) the utility model helps prolonging the useful life of voice coil loudspeaker voice coil because volume reduces, and therefore heat radiation is very fast.
(3) the more circular voice coil loudspeaker voice coil of the utility model when operation energising transmission sound wave distance is short, uses the tonequality of loudspeaker of this voice coil loudspeaker voice coil better.
(4) the utility model is seen from the angle of acoustics, and the sound wave of racetrack voice coil loudspeaker voice coil is difficult for passback, uses the tonequality of loudspeaker of this voice coil loudspeaker voice coil purer.

Embodiment 1
As shown in Figure 2; The present embodiment voice coil loudspeaker voice coil is run-track shaped; Be that voice coil loudspeaker voice coil cross section middle part is two parallel segments; Two end points of these two parallel segment the same sides connect two end points of 180 ° of circular arcs (being semi arch) of an evagination, and two end points of two parallel segment opposite sides also connect two end points of 180 ° of circular arcs (being semi arch) of an evagination, and two semicircle radiuses are identical and symmetrical.
The length of the strong point of this racetrack voice coil loudspeaker voice coil is 22.92mm, and the width of the widest part is 9.1mm, highly is 12.5mm.
Embodiment 2
The present embodiment voice coil loudspeaker voice coil is run-track shaped; Be that voice coil loudspeaker voice coil cross section middle part is two parallel segments; Two end points of these two parallel segment the same sides connect two end points of 120 ° of circular arcs of an evagination; Article two, two of the parallel segment opposite side end points also connect two end points of 120 ° of circular arcs of an evagination, and two 120 ° of arc radius are identical and symmetrical.
The length of the strong point of this racetrack voice coil loudspeaker voice coil is 18mm, and the width of the widest part is 8mm, highly is 16mm.
The above embodiment has only expressed the execution mode of the utility model; It describes comparatively concrete and detailed; But can not therefore be interpreted as restriction to the utility model claim; In every case adopt the technical scheme that form obtained that is equal to replacement or equivalent transformation, all should drop within the protection range of the utility model.
