Description

A kind of side goes out sound formula Microspeaker module

Technical field

The utility model belongs to the zund-Burguet apparatus technical field in communication device, is specifically related to a kind of side and goes out sound Microspeaker module.

Background technology

Under the background of electronic technology fast development, tracking exchage portable electric appts changes towards the direction such as light, thin, little, and applied miniature electro-acoustic device is also thereupon fast-developing. Because the electronic products such as mobile phone have more and more thinner trend, be limited to final assembly, Microspeaker module is not close to phone housing conventionally, and the sound that generally needs the leading note pipeline in mobile phone cavity loudspeaker could be produced is derived outside mobile phone. Meanwhile, in order to reduce the height of loudspeaker module, conventionally need to according to the requirement of complete machine structure carry out corresponding structure dodge design and side go out sound design. Therefore, the sound mouth that side goes out sound has comparatively complicated structure conventionally, easily causes the junction of mobile phone sound guide tube and loudspeaker module sound mouth to leak air, and has a strong impact on the tonequality of Microspeaker module.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple in structure, practical side and goes out sound Microspeaker module. In ensureing the acoustical behavior and architectural characteristic of product, design and supporting structure design by specific sound mouth, ensure again whole airtightness and the structural stability of the sealing ring of new construction, make product be not easy deformation occurs because of external force or come off. Meanwhile, the utility model does not increase the complexity of Microspeaker module group procedure technique, has ensured production efficiency and the competitiveness of product.

The utility model solves the problems of the technologies described above by the following technical programs,

A kind of side goes out sound formula Microspeaker module, comprises upper casing, lower casing, micro loudspeaker unit, draws FPC, it is characterized in that,

Described upper casing, micro loudspeaker unit, lower casing and draw FPC and superpose and be connected and installed successively, install sealing ring at the sound mouth place of lower casing, and described sealing ring is right-angled trapezium body, and its back side is rectangle, and side is right-angled trapezium; On the skew back face of right-angled trapezium body, be provided with continuant orifice.

As optimization, the upper mounting plate of described right-angled trapezium sealing ring is provided with stress relief hole;

As optimization, the position of the corresponding stress relief hole of described lower casing is provided with snap fit;

As optimization, the upper mounting plate of described right-angled trapezium sealing ring is provided with locating hole; The position of the corresponding locating hole of described lower casing is provided with locating dowel;

As optimization, described sealing ring and upper casing, lower casing contact-making surface are provided with gum;

As optimization, described sealing ring is rubber seal;

As optimization, the sound mouth surface on described lower casing is arcwall face.

The utility model is simple in structure, is not increasing under the prerequisite of module manufacturing process, has effectively strengthened the air-tightness of module and mobile phone sound guide tube junction. Reasonably design by the shell structure to loudspeaker module and sound mouth structure, effectively ensured stability and the reliability of this structure, reduced the risk of sealing ring perk in assembling process, improved product percent of pass, extended the life-span of product.

Detailed description of the invention

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

A kind of side goes out sound formula Microspeaker module, and comprise upper casing 1, micro loudspeaker unit 2, lower casing 3, sealing ring 4, screen cloth 5, draw FPC6,

Described upper casing 1, micro loudspeaker unit 2, lower casing 3 superpose and are connected and installed successively, at sound mouth 33 places of lower casing 3, sealing ring 4 are installed, and the surface of the sound mouth 33 on described lower casing 3 is arcwall face; Described sealing ring 4 is right-angled trapezium body, and its back side is rectangle, and side is right-angled trapezium; On the skew back face of right-angled trapezium body sealing ring 4, be provided with continuant orifice 41, post screen cloth 5 in the outside of continuant orifice; On the upper mounting plate of right-angled trapezium sealing ring, be provided with stress relief hole 42, the position of the corresponding stress relief hole 42 of lower casing is provided with snap fit 31; On the upper mounting plate of right-angled trapezium sealing ring, be also provided with locating hole 43, the position of the corresponding locating hole 43 of lower casing is provided with locating dowel 32; On sealing ring and upper casing, lower casing contact-making surface, be provided with gum; Described sealing ring is rubber seal; Upper casing and lower casing seal by ultrasonic realization, and draw wiring by drawing FPC6.

The surrounding that the sealing ring 4 of this routine utility model is close to the sound mouth 33 of the equipment such as mobile phone connects sealing to realize with continuant orifice 41. For the ease of connecting, upper casing has designed snap fit 31 structures at the correspondence position of sealing ring stress relief hole 42, utilize stress relief hole to coordinate with snap fit 31 as buckle, and make sealing ring gum, sealing ring can be by operator fixing by buckle and snap fit, and the location of locating dowel and locating hole is bonded at the surrounding of sound mouth 33. Like this, in the case of the processing procedure difficulty that is not significantly increased Microspeaker modular structure, greatly improve its air-tightness and installation uniformity.

Different from foam material, the heat resistance of quality of rubber materials is better, and shaping uniformity is better, can fit with the utility model shell better and realize better air-tightness. But rubber Young's modulus is higher, in order to realize better air-tightness, need to and be close to shell by sealing ring gum and be bonded at sound mouth 33 outer rims. Because the sound mouth 33 on lower casing of the present utility model is cambered surfaces, there is bending in sealing circle, so just has because of effect of stress and the risk of perk. The utility model has designed stress relief hole at the upper mounting plate bending part of sealing ring, to discharge the stress of sealing ring of quality of rubber materials, prevents the appearance of above-mentioned risk. In addition, on lower casing position corresponding to stress relief hole, design snap fit, utilized stress relief hole as buckle, allowed sealing circle can be fixed on better sound mouth 33 and go out, do not occurred the risk of sliding. Rubber ring can be injection molded, and operator is relatively easily positioned on rubber ring on the utility model upper casing by gum and buckle structure, has simplified corresponding processing procedure and technique. Like this, just realize the Microspeaker module design of easy assembling type, in the situation that not increasing product processing procedure, greatly improved air-tightness and the uniformity of product.
