Description
Technical field
The utility model relates to the water-proof rubber sleeve of electronic product, particularly relates to a kind of water-proof rubber sleeve for audio amplifier.
Background technology
Existing small size audio amplifier, for promoting overall sound quality effect and bass effect, usually on audio amplifier, increase the passive radiator of bass, be illustrated in figure 3 the cutaway view of the passive radiator of existing audio amplifier, wherein, the interior open link on outstanding limit 10 around and be fixedly connected on vibrating diaphragm 11, the outer shroud end on this outstanding limit 10 is fixedly connected with by glue, hot pressing etc. with support 9, be extended with a chamber 13 downwards in the bottom of vibrating diaphragm 11 in support 9, the outside of chamber 13 is arranged with and plays ripple 8, be provided with balancing weight 12 in chamber 13.The passive radiator of said structure, outer shroud end and the support 9 on outstanding limit 10 are discrete parts, although the two is fixedly connected with, but because vibrating diaphragm 11 is under long high-intensity oscillation condition, therebetween easily ftracture and form gap, thus affect waterproof, the humidity resistance of audio amplifier, harmful effect is caused to tonequality simultaneously.In addition, balancing weight 12 is arranged in chamber 13, and chamber 13 is fixed on the bottom of vibrating diaphragm 11 and to downward-extension, thus takies larger space, is difficult to the small size requirement meeting audio amplifier.
Utility model content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, provides one can improve the waterproof and dampproof performance of audio amplifier, makes audio amplifier keep excellent tonequality for a long time, avoids increasing audio amplifier volume and the simple water-proof rubber sleeve of structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
A kind of water-proof rubber sleeve for audio amplifier, its include be coated on casing of loudspeaker box gum cover body, be located at the passive radiator of gum cover body bottom portion and be surrounded on the Flexible Connector of passive radiator, described passive radiator includes waterproof top layer, a cavity is formed in described waterproof top layer, balancing weight is filled with, described gum cover body, waterproof top layer and Flexible Connector is all silica gel part and three in one is shaping in described cavity.
Preferably, the corresponding casing of loudspeaker box in the top of described gum cover body sound mouth and be provided with opening.
Preferably, inside twice bending of the top of described gum cover body and be formed with stepped fixed part.
Preferably, described fixed part is provided with slit.
The utility model is disclosed in the water-proof rubber sleeve of audio amplifier, due to gum cover body, waterproof top layer and Flexible Connector one-body molded, thus can effectively prevent from occurring cracking between three, gap etc., not only increase the waterproof of audio amplifier, humidity resistance, also make the tonequality that audio amplifier keeps excellent for a long time, simultaneously, balancing weight is hidden in the cavity on waterproof top layer, to avoid the thickness increasing passive radiator, make audio amplifier can meet small size requirement, in addition, this water-proof rubber sleeve is by mold injection molding, its structure is simple, be easy to realize, and the water-proof rubber sleeve of silica gel material has lower product cost.
Accompanying drawing explanation
Fig. 1 is the side sectional view of the utility model water-proof rubber sleeve.
Fig. 2 is the side sectional view of the audio amplifier that water-proof rubber sleeve is housed.
Fig. 3 is the cutaway view of the passive radiator of existing audio amplifier.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in more detail.
The utility model discloses a kind of water-proof rubber sleeve for audio amplifier, shown in composition graphs 1 and Fig. 2, it includes the gum cover body 1 being coated on casing of loudspeaker box 7, the Flexible Connector 3 be located at the passive radiator 2 bottom gum cover body 1 and be surrounded on passive radiator 2, described passive radiator 2 includes waterproof top layer 20, a cavity is formed in described waterproof top layer 20, balancing weight 21 is filled with, described gum cover body 1, waterproof top layer 20 and Flexible Connector 3 is all silica gel part and three in one is shaping in described cavity.
Above-mentioned water-proof rubber sleeve is sheathed on the outer surface of casing of loudspeaker box 7, due to gum cover body 1, waterproof top layer 20 and Flexible Connector 3 one-body molded, thus can effectively prevent from occurring cracking between three, gap etc., not only increase the waterproof of audio amplifier, humidity resistance, also make the tonequality that audio amplifier keeps excellent for a long time, simultaneously, balancing weight 21 is hidden in the cavity on waterproof top layer 20, do not increase the thickness of passive radiator 2, make audio amplifier can meet small size requirement, in addition, this water-proof rubber sleeve is by mold injection molding, its structure is simple, be easy to realize, and the water-proof rubber sleeve of silica gel material has lower product cost.
For avoiding blocking sound mouth, the sound mouth of the corresponding casing of loudspeaker box 7 in the top of described gum cover body 1 and be provided with opening 4.Be positioned near this opening 4, inside twice bending of top of described gum cover body 1 and be formed with stepped fixed part 5.This fixed part 5 is located between sound box mesh cover 8 and casing of loudspeaker box 7, at sound box mesh cover 8 with under the clamping action of casing of loudspeaker box 7, gum cover body 1 is fixed on the outer surface of casing of loudspeaker box 7, as a kind of optimal way, described fixed part 5 is provided with slit 6, the edge card of sound box mesh cover 8 is located in this slit 6, thus gum cover body 1 is fastening further.
The utility model is disclosed in the water-proof rubber sleeve of audio amplifier, gum cover body 1, waterproof top layer 20 and Flexible Connector 3 are one-body molded, not only increase the waterproof of audio amplifier, humidity resistance, also make the tonequality that audio amplifier keeps excellent for a long time, simultaneously, balancing weight 21 is hidden in the cavity on waterproof top layer 20, meet the small size requirement of audio amplifier, in addition, stepped fixed part 5 can be held between sound box mesh cover 8 and casing of loudspeaker box 7 more securely, makes the overall structure of audio amplifier more stable, reliable.
The above is the utility model preferred embodiment, is not limited to the utility model, all make in technical scope of the present utility model amendment, equivalent to replace or improvement etc., all should be included in scope that the utility model protects.
