Description

Thin-shaped speaker

The utility model is relevant a kind of loud speaker, and it is simple to refer in particular to a kind of compact conformation, thin thickness, the thin speaker that volume is little.

Loud speaker generally includes the pronunciation unit such as the buzzing sheet of tool function of pronunciation, and accommodates the pronunciation unit and promote toot the box of the resonating body of voice effect/altogether, relevant before the case technology can be with reference to Taiwan patent application the 85219651st and No. 85207127 case.Remained following weak point in these prior aries.See also shown in Figure 1: its short transverse H includes yoke 30 and magnet 40 parts etc. and all extends in outside the framework 10, its length is long, and cause its overall volume especially the size of short transverse greatly increase, therefore take bigger space, and unfavorablely carry and use in its transportation; Moreover its structure is also compact inadequately, and unfavorable the dwindling of its overall volume, and the development trend that this and loudspeaker body day of year convergent are little is disagreed.Though have relevant existing preceding case can make the length of the short transverse of speaker unit effectively obtain reduction in addition again, yet the composition member of this speaker unit is more, and causes its structure comparatively complicated, and overall weight also is difficult to obtain control.

The purpose of this utility model is to provide a kind of compact conformation simple, and overall volume is the thin speaker that do not taken up space by reduction of the size of short transverse especially.

The purpose of this utility model is achieved in that this Thin-shaped speaker comprises framework, auxiliary stand, yoke, magnet, voice coil loudspeaker voice coil and other assembly of elements, wherein framework is a bowl shaped structure, be provided with a planar bottom surface, have the circular hole of suitable internal diameter in planar bottom surface central authorities, auxiliary stand is arranged on the framework openend, yoke is diapire sealing, the cylinder of turned upside down, it is characterized in that: auxiliary stand intermediate disc place engages downwards yoke, be extended with magnet in the same way by downward in the middle part of the yoke and yoke, be the gap between magnet and yoke, opening one end of voice coil loudspeaker voice coil is arranged in the gap.

Side is provided with leg around the planar bottom surface of above-mentioned framework, and slightly is provided with some ladders in top at leg, and the another side relative with the framework planar bottom surface then be auxiliary stand, establishes a disk in the middle of it, by disk to around equal angles extend some support arms.

Auxiliary stand intermediate disc place engages downwards that yoke, yoke are arranged is the cylinder of diapire sealing, turned upside down, and its diapire edge extends downwards and terminates in the framework slightly that center is provided with a sidewall.Be placed with the smaller magnet of a diameter in the middle of the yoke diapire, the length dimension that length dimension that it extends downwards and yoke extend downwards is suitable.Voice coil loudspeaker voice coil also tool is cylindric, is made up of side on every side, and its bottom surface is the dust cap of a voice coil loudspeaker voice coil.

Coil and the gap location of yoke be one group of coil solderless wrapped connection is on voice coil loudspeaker voice coil mutually, cone one end is overlapped on the side of voice coil loudspeaker voice coil, the other end then is overlapped on the set ladder of framework.And play the engage sides of ripple one end and voice coil loudspeaker voice coil, the other end then engages with planar bottom surface.

Compare prior art, because member such as yoke and magnet and voice coil loudspeaker voice coil all is arranged on the inside of framework in the utility model, thereby compact conformation, overall volume particularly its short transverse size oneself almost reduce by half, and the effect of loud speaker itself does not become, thereby has reached the purpose of this utility model.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the cutaway view of existing loud speaker.

Fig. 2 is the cutaway view of the utility model Thin-shaped speaker.

Fig. 3 is the front view of the utility model Thin-shaped speaker.

Fig. 4 is the rearview of the utility model Thin-shaped speaker.

See also shown in Figure 2, the utility model Thin-shaped speaker comprises framework 10, auxiliary stand 20, yoke 30, magnet 40, voice coil loudspeaker voice coil 50 and other assembly of elements, wherein framework 10 is a bowl shaped structure, be provided with a planar bottom surface 11, have the circular hole 12 of suitable internal diameter in planar bottom surface 11 central authorities, side is provided with leg 13 around planar bottom surface 11 again, and slightly is provided with some ladders 14 in top at leg 13.

Please consult Fig. 3 and shown in Figure 4 simultaneously, set up an auxiliary stand 20 with the openend 110 of framework 10, establish a disk 21 in the middle of it, by disk 21 to around equal angles extend some support arms 22, engage with ladder 14 tops of framework 10, to reach the firm winding of 10 of auxiliary stand 20 and frameworks.

Engage downwards at auxiliary stand 20 intermediate discs 21 places that yoke 30, yoke 30 are arranged is the cylinder of a diapire 31 sealings, turned upside down, its diapire 31 edges extend downwards and terminate in the framework 10 slightly that center are provided with a sidewall 32.Again, be placed with the smaller magnet of a diameter 40 in the middle of yoke 30 diapires 31, the length dimension that length dimension that it extends downwards and yoke 30 extend downwards is suitable.Voice coil loudspeaker voice coil 50 also tool is cylindric, and around forming, its bottom surface 52 has dust cap 53 by side on every side 51, can be for covering foreign material and dust.Other assembly of elements includes coil 60, cone 70 and plays ripple 80 etc. and all engages by adhesive with sound Figure 50 etc.

According to above-mentioned member, assembly relation to element is further elaborated, the ladder 14 top windings of framework 10 have auxiliary stand 20, auxiliary stand 20 intermediate discs 21 places engage downwards yoke 30, by yoke 30 middle parts downwards and yoke 20 be extended with magnet 40 in the same way, 30 of magnet 40 and yokes are gap 41, opening 54 1 ends of voice coil loudspeaker voice coil 50 are arranged in the gap 41, and by its opening 54 so that magnet 40 1 end groups are gone in it, the other end of voice coil loudspeaker voice coil 50 is bottom surface 52, oneself pass the set circular hole 12 of framework 10 planar bottom surface 11 its, and have partly and extend in outside the planar bottom surface 11.

Coil
