Abstract
The utility model discloses a thin double-magnetic-circuit horn, which belongs to the technical field of horns. The thin double-magnetic-circuit horn is technically mainly characterized by comprising a support. A paper cone is arranged on the support, two voice coils are arranged in the rear of the paper cone, a damper is arranged between the two voice coils, the outer edge of the damper is fixedly connected with the support, and the middle of the damper is fixedly connected with the paper cone. The thin double-magnetic-circuit horn aims to be simple in structure, low in horn distortion and long in service life, and is used for playing sounds.
Description
Technical field
The utility model relates to a kind of loudspeaker, more particularly, relates in particular to a kind of slim double magnetic circuit PC Speaker.
Background technology
In order to cooperate the lightening of electronic product, the loudspeaker of use for electronic products are also toward the slimming development now, and still under the loudspeaker slimming, the sensitivity of loudspeaker (volume) must guarantee with traditional loudspeaker approaching as far as possible.Traditional double magnetic circuit loudspeaker, two voice coil loudspeaker voice coils all are to dispose one separately to play ripple, be used to guarantee the operate as normal of voice coil loudspeaker voice coil, because loudspeaker slimming, make the inner space dwindle, the main influence that causes is exactly the bullet ripple design of thin type horn and installs very difficult, the loudspeaker of some small-sized slimming even the bullet ripple can't be installed, having lost the braking and the center that play ripple keeps, when moving back and forth, voice coil loudspeaker voice coil can't remain on the center in magnetic gap, make and cause the loudspeaker job insecurity distortion of speaker sound and shortened its useful life.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, the loudspeaker distortion is little, the slim double magnetic circuit loudspeaker of long service life.
The technical solution of the utility model is achieved in that a kind of slim double magnetic circuit loudspeaker, comprise support, on support, be provided with cone, be provided with two voice coil loudspeaker voice coils at the cone rear portion, wherein, be provided with the bullet ripple between described two voice coil loudspeaker voice coils, this outer rim that plays ripple is fixedlyed connected with support, plays the ripple middle part and fixedlys connected with cone.
In the above-mentioned slim double magnetic circuit loudspeaker, described two voice coil loudspeaker voice coils are symmetricly set on the both sides that play ripple substantially.
In the above-mentioned slim double magnetic circuit loudspeaker, fixedly connected with cone by adapter sleeve in described bullet ripple middle part.
In the above-mentioned slim double magnetic circuit loudspeaker, the overall structure that described adapter sleeve and cone are formed in one.
In the above-mentioned slim double magnetic circuit loudspeaker, the overall structure that described adapter sleeve and bullet ripple are formed in one.
After the utility model adopts said structure, play ripples by an original voice coil loudspeaker voice coil being cooperated a bullet ripple make shared one of two voice coil loudspeaker voice coils into, being about to play ripple is arranged in the middle of two voice coil loudspeaker voice coils, fixedly connected with support with cone respectively, promptly saved material, reduce the distortion of loudspeaker again, and made the voice coil loudspeaker voice coil working stability, prolonged the useful life of loudspeaker.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Among the figure: support 1, cone 2, voice coil loudspeaker voice coil 3, bullet ripple 4, adapter sleeve 5.
Embodiment
Consult shown in Figure 1, a kind of slim double magnetic circuit loudspeaker of the present utility model, comprise support 1, on support 1, be provided with cone 2, be provided with two voice coil loudspeaker voice coils 3 at cone 2 rear portions, between two voice coil loudspeaker voice coils 3, be provided with 4, two voice coil loudspeaker voice coils 3 of bullet ripple and be symmetricly set on bullet ripple 4 both sides substantially, this outer rim that plays ripple 4 is fixedlyed connected with support 1, plays ripple 4 middle parts and fixedlys connected with cone 2 by adapter sleeve 5.In the present embodiment, play the replacing of ripple 4 for convenience, adapter sleeve 5 and cone 2 are designed to integrated overall structure, play ripple 4 and fixedly connected with the other end of adapter sleeve 5.Can conveniently play the replacing of ripple 4 like this, can be as required, the difform bullet ripple 4 of arranging in pairs or groups.Certainly, adapter sleeve 5 can be integrated overall structures with playing ripple 4 also, and the other end of adapter sleeve 5 is fixedlyed connected with cone 2.As required, can adopt different connected modes.
