CN201657242U - Wiring board for microphone - Google Patents

Abstract

The utility model discloses a wiring board for a microphone; the wiring board is provided with at least a through hole and a sound hole; the sound hole is composed of a plurality of fine holes; the plurality of fine holes includes a center hole and a plurality of star holes which are uniformly distributed around the center hole; compared with conventional single type sound hole structure, the sound transmission effect of the sound hole structure composed of fine holes is not decreased; the fine hole is beneficial to prevent external dusts or impurities from entering so as to play a dustproof effect; thereby the product quality is improved and the service life of the product is prolonged.

Description

The microphone wiring board

Technical field

The utility model relates to the microphone art, refers in particular to the circuit board structure that a kind of microphone is used.

Background technology

Along with developing rapidly of current science and technology, the microphone art is also constantly being upgraded, for example, everybody uses maximum electret capacitor microphone (ECM) to be replaced by a kind of new silicon microphone before, yet, no matter be electret capacitor microphone or silicon microphone, in order to cooperate the installation needs of electronic product, portioned product all needs to offer in the circuit board hole in the microphone, realize the requirement of " zero elevation " when installing or satisfy acoustical behavior such as directive property to reach on the electronic product wiring board, when making the main body of microphone be installed on the electronic product wiring board, do not increase the height on the electronic product wiring board.Yet, though the existing sound pore structure of offering on wiring board can satisfy aforesaid basic function and needs, but when using, reality finds still to have many deficiencies on himself structure and the serviceability, fail to reach best result of use and task performance, particularly traditional sound pore structure is single formula pore space structure, and for satisfying transaudient needs, the diameter of its hole is all bigger, thus, usually the problem of Chu Xianing is, microphone is after use after a while, and outside impurity such as dust constantly enter microphone inside by this hole, finally have influence on the service behaviour and the useful life of microphone inner member, bring quality hidden danger.

The utility model content

Main purpose of the present utility model provides a kind of microphone circuit board structure, solves the dustproof problem in microphone sound hole.

For achieving the above object, the utility model adopts following technical scheme:

A kind of microphone wiring board, wiring board are provided with at least oneization hole and a hole, and this hole is to be made up of a plurality of pores.

As a kind of preferred version, described a plurality of pores include a centre bore and center on the equally distributed a plurality of stars of this centre bore hole.

As a kind of preferred version, described star pore size distribution is on same circumference.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, as shown from the above technical solution, it mainly is that the sound hole is designed to the structure be made up of a plurality of pores, the sound pore structure that these pores are formed is for the single formula sound pore structure of tradition, and its transaudient effect never weakens to some extent, but pore helps stopping that outside dust or impurity enter, play the dustproof effect, mat and reaching improves product quality, prolongs the product effect in useful life.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

Description of drawings

Fig. 1 is the front view of the embodiment of the utility model;

Fig. 2 is the side direction view of Fig. 1;

Fig. 3 is the reverse view of Fig. 1.

The accompanying drawing identifier declaration:

10, wiring board

11, change the hole

12, sound hole

121, centre bore

122, star hole

Embodiment:

Please refer to Fig. 1 to shown in Figure 3, it has demonstrated the concrete structure of the preferred embodiment of the utility model, a kind of microphone wiring board 10, wiring board 10 is provided with two and changes hole 11 and a hole 12, this change hole 11 is used for the Copper Foil of wiring board upper and lower surface is electrically connected, and this hole 12 is to be made up of a plurality of pores.

Particularly, these a plurality of pores include a centre bore 121 and center on these centre bore 121 equally distributed four star holes 122, and these star holes 122 preferably are to be distributed on the same circumference.

Certainly, aforementioned a plurality of pores both had been not limited to the distributed architecture shown in the figure, also were not limited to the quantity shown in the figure, and it can also be designed to any other distribution mode and quantity, does not exceed with it.

In sum, design focal point of the present utility model is, it mainly is that the sound hole is designed to the structure be made up of a plurality of pores, the sound pore structure that these pores are formed is for the single formula sound pore structure of tradition, its transaudient effect never weakens to some extent, but pore helps stopping outside dust or impurity and enters, and plays the dustproof effect, mat and reach and improve product quality, prolong the product effect in useful life.

The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.

Claims (3)

1. microphone wiring board, wiring board is provided with hole and at least oneization hole, it is characterized in that: this hole is for to be made up of a plurality of pores.

2. microphone wiring board according to claim 1 is characterized in that: described a plurality of pores include a centre bore and center on the equally distributed a plurality of stars of this centre bore hole.

3. microphone wiring board according to claim 1 is characterized in that: described star pore size distribution is on same circumference.
