Abstract
The utility model discloses a voice coil, which is formed by continuously winding voice coil wires, wherein the adjacent voice coil wires are in face contact. The voice coil has good firmness and high sensitivity.
Description
[technical field]
The utility model relates to a kind of voice coil loudspeaker voice coil, particularly a kind of voice coil loudspeaker voice coil that is used on the minitype acoustic generator.
[background technology]
Along with improving constantly of the market demand, mobile phone develops to the slimming direction gradually, and requires its sound quality to become better and better, and this just requires the acoustical generator in the mobile phone to develop towards small-sized, slim, high tone quality direction.Voice coil loudspeaker voice coil is the core component of minitype acoustic generator such as loud speaker, and the requirement of its acoustical behavior is also just improved thereupon.
Please join shown in Figure 3, the voice coil loudspeaker voice coil of correlation technique (not label), it is entwined by continuous voice coil line 11 ', the cross section of described voice coil line 11 ' is rounded.
Yet, be the voice coil loudspeaker voice coil that circular voice coil line 11 ' is wound in by the cross section, rely on the line contact to combine between adjacent voice coil line 11 ', its adhesion is lower, causes voice coil loudspeaker voice coil insecure.In addition, the sensitivity of this voice coil loudspeaker voice coil is lower.
Therefore, be necessary to provide a kind of improved voice coil loudspeaker voice coil, satisfy demands of applications.
[utility model content]
The voice coil loudspeaker voice coil that provides a kind of fastness good, highly sensitive is provided the purpose of this utility model.
The purpose of this utility model is achieved in that a kind of voice coil loudspeaker voice coil, and it is entwined by continuous voice coil line, wherein, is the face contact between described adjacent voice coil line.
The utlity model has following advantage: under the situation identical in resistivity, that magnetic gap is identical, voice coil loudspeaker voice coil of the present utility model is compared with relevant technology, and its fastness is good, highly sensitive.
[description of drawings]
Fig. 1 is the stereogram of the utility model voice coil loudspeaker voice coil.
Fig. 2 is the cutaway view along the II-II line shown in Figure 1.
Fig. 3 is the cutaway view of correlation technique voice coil loudspeaker voice coil.
[embodiment]
Below in conjunction with accompanying drawing, the utility model voice coil loudspeaker voice coil is elaborated.
Please refer to illustrated in figures 1 and 2ly, the utility model voice coil loudspeaker voice coil 1 is used for minitype acoustic generators such as Microspeaker or receiver.
Voice coil loudspeaker voice coil 1 integral body is tubular, and it is entwined by continuous voice coil line 11, and this voice coil line 11 comprises metal wire 12 and wraps the insulating barrier 13 of being located at metal wire 12 peripheries.The cross section of described voice coil line 11 is a rectangle, and the cross section of metal wire 12 also is a rectangle.As shown in Figure 2, the employing cross section is the voice coil loudspeaker voice coil 1 that the voice coil line 11 of rectangle is entwined, and 11 of its adjacent voice coil line are the face contact.
11 of adjacent voice coil line are the face contact, certainly will strengthen the fastness of voice coil loudspeaker voice coil 1.
Voice coil loudspeaker voice coil of the present utility model is compared with the voice coil loudspeaker voice coil of relevant technology, suppose that adopting diameter in the correlation technique is the circular metal wire-wound system of 0.06mm, under the identical situation of resistivity, voice coil loudspeaker voice coil of the present utility model then adopts the rectangular metal wire-wound system of the length * wide 0.053 * 0.053mm of being, in the same magnetic gap, the effective length of voice coil loudspeaker voice coil of the present utility model has increased about 1.13 times, the sensitivity that can improve about 1dB accordingly.
In the present embodiment, the cross section of voice coil line is a rectangle, and voice coil line also can be structures such as rhombus in fact.The cross sectional shape of voice coil line both can for the face contact between described adjacent voice coil line as long as guarantee.The shape of described insulating barrier can be complementary with the shape of metal wire, also can be not and the form fit of metal wire.The cross section of metal wire also can be arbitrary shapes such as rhombus.
The above only is a better embodiment of the present utility model; protection range of the present utility model does not exceed with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
