Abstract
The utility model relates to an audio engineering field, concretely relates to speaker convenient to it is fixed, including shell and the compound vibrating diaphragm of setting in the shell, the shell sub -unit connection has the vacuum chuck of gluey system, and the shell side is equipped with the fin, and last the opening of vacuum chuck has one to run through the surperficial evacuation pore of here sucking disc, and compound vibrating diaphragm is equipped with adoption organosilicon pressure sensitive adhesive in proper order and is the damping glue film of material and the release film layer who adopts the PE material including the substrate layer that adopts polyphenylene sulfide to be the material on the upper surface of substrate layer. The utility model discloses the structural fin that utilizes around the shell dispels the heat, prevents the ageing serious phenomenon that speaker high temperature caused, vacuum chuck's structure makes fixed that the speaker can be random, has increased the stability and the adsorptivity of speaker, the utility model discloses a compound vibrating diaphragm has set up damping glue film and release film layer at the upper surface of substrate layer for the damping of substrate layer is fallen the characteristic of making an uproar and is strengthened.
Description
Technical field
The utility model belongs to electroacoustic techniques field, is specifically related to a kind of loud speaker being convenient to fix.
Background technology
Loud speaker in earphone can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.Traditional loud speaker is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In the loud speaker of each type, using is dynamic speaker at most, the most widely, is also called coil-moving speaker.
Along with improving constantly of the market demand, loud speaker to slimming future development, and requires that its sound quality is become better and better, and vibrating diaphragm is the core component of the acoustical devices such as loud speaker, also just improves the requirement of its acoustical behavior thereupon.Vibrating diaphragm in relevant technology can be difficult to a kind of single film the transaudient effect reaching vibrating membrane loudspeaker low frequency, composite diaphragm is following a kind of development trend, also have existing loud speaker when fixing, need auxiliary fixed mount, fixed installation inconvenient operation.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of loud speaker being convenient to fix, overcome the deficiencies in the prior art, reasonable in design, compact conformation, because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevent the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker.
The technical solution adopted in the utility model is as follows:
A kind of loud speaker being convenient to fix, the composite diaphragm comprising shell and arrange in the enclosure, described outer casing underpart is connected with the vacuum cup that glue is made, described shell side is provided with fin, described fin is annular, described fin is provided with multi-disc and is distributed in case surface from top to bottom successively, described vacuum cup has one run through this chuck surface vacuumize duct, it is the substrate layer of material that described composite diaphragm comprises employing polyphenylene sulfide, the upper surface of substrate layer is provided with successively from top to bottom and adopts organic pressure-sensitive gel to be the damping glue-line of material and the release film layer of employing PE material.
The thickness of described substrate layer is 10 μm.
The thickness of described damping glue-line is 10 μm.
The thickness of described release film layer is 20 μm.
Described fin and shell are by being welded and fixed.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model provides a kind of loud speaker being convenient to fix, and because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevents the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker; Composite diaphragm of the present utility model, be provided with damping glue-line and release film layer at the upper surface of substrate layer, the damping noise-reducing characteristic of substrate layer strengthened, it is applied in Music centre loudspeaker, can reduce noise, presents good acoustical quality.

Fig. 2 is the utility model structural representation.
Reference numeral is as follows:
1: substrate layer, 2: damping glue-line, 3: release film layer, 4: shell, 5: vacuum cup, 6: fin, 7: vacuumize duct.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, should be appreciated that structure of the present utility model is not limited in following examples:
As shown in Figure 1 and Figure 2, a kind of loud speaker being convenient to fix, the composite diaphragm comprising shell 4 and be arranged in shell 4, shell 4 bottom is connected with the vacuum cup 5 that glue is made, shell 4 side is provided with fin 6, fin 6 is annular, and fin 6 is provided with multi-disc and is distributed in shell 4 surface successively from top to bottom, and described fin 6 and shell 4 are by being welded and fixed.Vacuum cup 5 has one run through this chuck surface vacuumize duct 7, composite diaphragm comprises the substrate layer 1 that employing polyphenylene sulfide is material, the upper surface of substrate layer 1 is provided with successively from top to bottom and adopts organic pressure-sensitive gel to be the damping glue-line 2 of material and the release film layer 3 of employing PE material, in the present embodiment, the thickness of substrate layer 1 is 10 μm, the thickness of damping glue-line 2 is 10 μm, and the thickness of release film layer 3 is 20 μm.
The utility model provides a kind of loud speaker being convenient to fix, and because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevents the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker; Composite diaphragm of the present utility model, be provided with damping glue-line and release film layer at the upper surface of substrate layer, the damping noise-reducing characteristic of substrate layer strengthened, it is applied in Music centre loudspeaker, can reduce noise, presents good acoustical quality.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technology people of this area should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
