Abstract
The utility model discloses a nylon silk yarn voice coil, which comprises a cylindrical voice coil frame and a voice coil wire which forms coils of the voice coil by winding on the voice coil frame. The nylon silk yarn voice coil is characterized in that the voice coil wire is nylon silk yarn. As the voice coil disclosed by the utility model adopts the nylon silk yarn, so that the fatigue resisting capacity of the voice coil is improved, and the voice coil is prevented from cracking because of stress fatigue.
Description
Technical field
The utility model relates to the loud speaker field, particularly a kind of bright and beautiful silk thread voice coil loudspeaker voice coil.
Background technology
The voice coil loudspeaker voice coil of loud speaker is one of core component of loud speaker, and it produces high-frequency vibration under the effect of high-frequency current, sounds thereby drive the diffuser vibrations.Present loudspeaker voice coil mostly is single copper cash (aluminum steel etc.), or the voice coil loudspeaker voice coil coil adopts copper-clad aluminum conductor and at speech coil framework pad is set and welds bright and beautiful silk thread, such voice coil loudspeaker voice coil exists defective, following power of loudspeaker continues to improve, copper cash (aluminum steel) voice coil loudspeaker voice coil breaks because temperature is too high easily, and under the long-term vibrations of loud speaker, voice coil loudspeaker voice coil is also easily because the not high reason broken string of intensity own; Speech coil framework is provided with the voice coil loudspeaker voice coil of pad in addition and since pad very high the impedance of coil, comparatively concentrated at weld stress, also cause the problem of pad fracture easily.
Summary of the invention
The purpose of this utility model provides a kind ofly can bear high-power durable bright and beautiful silk thread voice coil loudspeaker voice coil.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bright and beautiful silk thread voice coil loudspeaker voice coil, and it comprises speech coil framework cylindraceous, is wrapped in the voice coil line that forms the voice coil loudspeaker voice coil coil on the described speech coil framework, and described voice coil line is bright and beautiful silk thread.
Preferably, described bright and beautiful silk thread is mixed to twist by multiple wire rod and forms.
Further preferably, described bright and beautiful silk thread comprises yellow gold twisted wire, copper-alloy stranded conductor, yellow gold litzendraht wire.
Preferably, stretch out from the tangential direction of described voice coil loudspeaker voice coil coil respectively at the two ends of described bright and beautiful silk thread.
Because technique scheme is used, the utility model compared with prior art has following advantage:
1, because the utility model voice coil line adopts bright and beautiful silk thread, improves the anti-fatigue ability of voice coil loudspeaker voice coil own, avoided voice coil line because stress fatigue causes fracture.
2, owing on the utility model speech coil framework pad is not set, can effectively prevent from having reduced the impedance of voice coil loudspeaker voice coil simultaneously because weld stress concentrates disconnected easily situation to occur.
Description of drawings
Accompanying drawing 1 is the utility model schematic top plan view;
Accompanying drawing 2 is looked schematic diagram for the utility model master;
Accompanying drawing 3 is looked schematic diagram for existing voice coil loudspeaker voice coil master.
In the above accompanying drawing: 1, speech coil framework; 2, voice coil loudspeaker voice coil coil; 3, copper cash; 4, bright and beautiful silk thread; 5, pad.
Embodiment
Be further described below in conjunction with the utility model of embodiment shown in the drawings:
Embodiment one:
As shown in Figure 3, existing a kind of voice coil loudspeaker voice coil, it comprises speech coil framework 1 cylindraceous, is wrapped in the voice coil line that forms voice coil loudspeaker voice coil coil 2 on the described speech coil framework 1, described voice coil line is copper cash 3, speech coil framework 1 is provided with pad 5, one end of the end of described copper cash 3 and bright and beautiful silk thread 4 is welded on the described pad 5, and bright and beautiful silk thread 4 leads to the voice coil loudspeaker voice coil outside.
Shown in accompanying drawing 1-2, a kind of bright and beautiful silk thread voice coil loudspeaker voice coil after the improvement, it comprises speech coil framework 1 cylindraceous, is wrapped in the voice coil line that forms voice coil loudspeaker voice coil coil 2 on the described speech coil framework 1, described voice coil line is that the yellow gold strand is mixed the bright and beautiful silk thread 4 of strand, and stretch out from the tangential direction of described voice coil loudspeaker voice coil coil 2 respectively at the two ends of described bright and beautiful silk thread 4.
Contrast before and after improving: the voice coil line after the improvement adopts bright and beautiful silk thread 4, has improved voice coil loudspeaker voice coil coil 2 anti-fatigue abilities own, avoids voice coil loudspeaker voice coil coil 2 because stress fatigue causes fracture; On the speech coil framework 1 after the improvement pad 5 is not set, can effectively prevents from having reduced the impedance of voice coil loudspeaker voice coil simultaneously because pad 5 place's stress concentrate disconnected easily situation to occur.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection range of the present utility model.
