Abstract

The utility model discloses a loudspeaker with a composite diaphragm, which aims at providing the loudspeaker with the composite diaphragm, pure tone, full bass and simultaneous sonorous medium high frequency. The loudspeaker with the composite diaphragm comprises a bracket; a magnetic shield is arranged at the rear of the bracket and is internally fixed with magnetic steel and a pole piece; diaphragm voice coils are arranged around the magnetic steel and the pole piece; the loudspeaker with the composite diaphragm is characterized in that the diaphragm voice coil is connected with the composite diaphragm at the front of the pole piece; the composite diaphragm incluses a basement membrane with a vibrating diaphragm folding ring forwards in sequence, wherein the basement membrane consists of a PAR (Polyaryl Amide) thin film and a PU (Poly Urethane) thin film; and a sphere top on the basement membrane is bonded through a woody sheet and a binding agent for an aluminum membrane in sequence. The sphere top of the composite diaphragm is made of the woody sheet and the aluminum membrane, so that the rigidity of the sphere top is ensured; meanwhile, the aluminum membrane has light weight so that the loudspeaker has good low frequency response, low fo and very perfect tone.

Description

The loud speaker of band composite diaphragm
Technical field
The utility model relates to loud speaker, relates in particular to a kind of loud speaker with composite diaphragm.
Background technology
Electronics and communication product equipment such as employed mobile phone, PDA, notebook computer, digital camera, MP3, MP4 in the modern life require to the sound of loud speaker that tone color is pure, bass is plentiful, medium-high frequency also requires loud and clear simultaneously.But because the volume of electronic product is more and more littler; The space that the design of each body places for loud speaker or receiver is very limited; Therefore the required also greatly reduction of back cavity volume space of loud speaker; Cause loud speaker can not bring into play best efficiency, the low frequency part loss is serious, and therefore inventing the ultralow frequency Microspeaker just becomes development today trend.And present PU material just can not satisfy above-mentioned requirements as vibrating membrane.
The utility model content
The purpose of the utility model provides the loud speaker of the band composite diaphragm that a kind of tone color is pure, bass is plentiful, medium-high frequency is simultaneously loud and clear.
In order to achieve the above object; The technical scheme of the utility model is: include support, support is the magnetic cover at the back, and magnetic cover internal fixation has magnet steel, pole piece; Around magnet steel and the pole piece is the vibrating diaphragm voice coil loudspeaker voice coil; The composite diaphragm that it is characterized in that vibrating diaphragm voice coil loudspeaker voice coil and pole piece front is connected, and described composite diaphragm includes the counterdie of PAR film and the compound composition band of PU film vibrating membrane ring successively forward, and ball on counterdie top adopts wooden to use adhesives with the aluminium film successively.
The thickness of said counterdie is 0.05 millimeter.
Said wooden thickness is 0.3~0.4 millimeter.
The thickness of said aluminium film is 0.05 millimeter.
The loud speaker of the band composite diaphragm of making according to such scheme, the ball top portion of its composite diaphragm adopt wooden with the aluminium film, guaranteed the rigidity of ball top portion, the aluminium film has light weight simultaneously, makes the loud speaker LF-response good, fo is low, tone color is very perfect.
Description of drawings
Fig. 1 is the front view of the loud speaker of band composite diaphragm;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the profile of composite diaphragm.
Among the figure: 1, support; 2, magnetic cover; 3, magnet steel 4, pole piece 5, vibrating diaphragm voice coil loudspeaker voice coil 6, composite diaphragm; 7, PAR film; 8, PU film; 9, vibrating membrane ring 10, wooden; 11, aluminium film 12, adhesive.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Fig. 1, Fig. 2 are the structural representations of the loud speaker of band composite diaphragm.From figure, find out, include support 1, support 1 back is a magnetic cover 2, and magnetic cover 2 internal fixation have magnet steel 3, pole piece 4, are vibrating diaphragm voice coil loudspeaker voice coil 5 around magnet steel 3 and the pole piece 4, and vibrating diaphragm voice coil loudspeaker voice coil 5 is connected with the composite diaphragm 6 of pole piece 4 fronts.Described composite diaphragm 6 is as shown in Figure 3, and it includes the counterdie of PAR film 7 and PU film 8 compound composition band vibrating membrane rings 9 successively forward, and the ball top on the counterdie adopts wooden 10 to bond with aluminium film 11 usefulness adhesives 12 successively.Wherein the thickness of counterdie is 0.05 millimeter, and wooden 10 thickness is 0.3~0.4 millimeter, and the thickness of aluminium film 11 is 0.05 millimeter.
