Abstract
The invention relates to a microphone dustproof structure, comprising a microphone body and a circuit board. The microphone body is arranged in a microphone sound inlet channel, is fixed on the circuit board, and is provided with a sound inlet and a dustproof device covering the sound inlet. After the microphone dustproof structure disclosed by the invention is adhered on the surface in an assembling process, the dustproof screen is immediately adhered on the sound inlet of the microphone body, thus the risk of pollution by dust impurity can be avoided in the processes of assembling a machine and conveying the machine, the damage on a vibration film due to the dust in a communication terminal machine can be avoided, and the protection on the microphone is more direct and complete; simultaneously, the microphone dustproof structure has a dustproof function when being used by a user, the risk of microphone disability is reduced to the maximum extent, and the communication quality and the microphone reliability are improved.
Description
Technical field
The present invention relates to the microphone on the call terminal equipment, especially the dustproof construction of microphone.
Background technology
In view of the principle of microphone; Why microphone can pick up sound, is to produce vibration through the extraneous air-flow of speaking of vibrating diaphragm induction, and this vibration causes changes in capacitance between microphone diaphragm and another pole plate; Thereby obtain an electric wave signal, accomplish the conversion of acoustic-electric.When vibrating diaphragm vibrates when undesired, this acoustic-electric conversion is also undesired, will influence speech quality.So guarantee that the normal vibration of vibrating diaphragm is the key point of microphone operate as normal.
Use to the consumer from the production of microphone, assembling, the residing environment of microphone all can have influence on vibrating diaphragm again, the dust impurity in the environment especially, and water droplet liquid etc. all can cause the undesired vibration of vibrating diaphragm.In general; Microphone all can be accomplished under the production environment in strictness in the process of producing; Vibrating diaphragm receives the introduced contaminants effect very little, and vibrating diaphragm receives the pollution of impurity, liquid etc., all is basically in assembling of the later stage of microphone and consumer's use.So the enforcement of dust prevention also all is to use this two stages in assembling and consumer.Usually the way that adopts is: 1. control the clean environment degree of composing room, solve the dustproof anti-liquid problem in assembling stage; 2. in advancing of microphone one deck Air Filter is set in the sound passage, solves the dustproof anti-liquid problem in user's use.Though these two kinds of ways can have certain help to dustproof feed liquor of microphone etc., effect is limited.
Summary of the invention
Contaminated and influence the problem of tonequality in order to solve microphone diaphragm, the invention provides a kind of microphone dustproof construction and assemble method thereof with good dustproof effect.
The present invention realizes above-mentioned technical purpose through following technical scheme.
A kind of microphone dustproof construction; Comprise microphone body, circuit board, said microphone body is positioned at microphone and advances the sound passage and be fixed on the circuit board; Said microphone body is provided with sound inlet, dust guard is set on the said microphone body covers sound inlet.
Preferably, said dust guard is an Air Filter, and said Air Filter is arranged on the shell of said microphone body.
The dust percent of pass of the dust guard that preferably, is provided with on the said microphone body is more said, and to advance the dust percent of pass of the dust guard that is provided with in the sound passage little.
The assemble method of microphone dustproof construction according to the invention is characterized in that, after microphone body mounts on the substrate through surface mounting technology (SMT), immediately said dust guard is assembled on the said microphone body.
The beneficial effect of technical scheme according to the invention is:
Microphone dustproof construction according to the invention covers sound inlet through dust guard is set on microphone body; Owing in assembling process, after microphone body mounts on the substrate through surface mounting technology (SMT), immediately said dust guard is assemblied on the said microphone body.After so just can avoiding SMT to accomplish, dust impurity gets into microphone body in complete machine assembling and handling process, pollutes the risk and the probability of the vibrating diaphragm in the microphone body.Simultaneously, in user's use, also can play effect, maximizedly reduce the risk that microphone lost efficacy the proofing dust and protecting of microphone body, to the protection of microphone more directly, more thorough, improve the reliability of speech quality and microphone.
Description of drawings
Fig. 1 is a microphone dustproof construction sketch map according to the invention.
Among the figure:
The 1-microphone body, the 2-sound inlet, 3-dust guard, 4-advance the sound passage, the 5-circuit board.
Embodiment
Embodiment for clearer description technical scheme of the present invention is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1; Microphone dustproof construction according to the invention comprises: microphone body 1, and circuit board 5, said microphone body 1 is positioned at microphone and advances sound passage 4 and be fixed on the circuit board 5; Said microphone body 1 is provided with sound inlet 2, and said sound inlet 2 places are provided with dust guard 3.The dust guard 3 that is adopted among the present invention is Air Filter or dust cover, no matter adopts which kind of dust guard, must cover the sound inlet 2 of said microphone body 1 when being provided with.When adopting Air Filter, Air Filter is arranged on the shell of microphone body 1 at said sound inlet 2 places.
Microphone dustproof construction according to the invention can be applied on the terminal equipment that mobile phone, telephone set, intercom, palmtop PC (being called for short PDA), notebook computer etc. can converse.In assembling process; The best opportunity that dust guard 3 pastes sound inlet 2 places on the microphone body 1 is after microphone body 1 mounts on the substrate through surface mounting technology (SMT), to be assembled to immediately on the microphone body 1; After so just can avoiding SMT to accomplish; Dust impurity gets into microphone body 1 in assembling complete machine and handling process, pollutes the risk and the probability of the vibrating diaphragm in the microphone body 1.Simultaneously, when cause the inner entering of terminal equipment dust owing to other reasons after, the dust guard 3 at microphone body 1 sound inlet 2 places can prevent pollution and the destruction of the inner dust of terminal equipment to its vibrating diaphragm, plays the effect of secondary dustproof.Promptly in user's use, also play protective effect to microphone body 1, the risk that maximized reduction microphone lost efficacy, more direct to the protection of microphone, more thorough, the reliability of raising speech quality and microphone.
Above execution mode is merely indivedual embodiment of the present invention; Those skilled in the art are that multiple conspicuous improvement and replacement can be made in the basis with technical scheme of the present invention, and any conspicuous improvement and the replacement on the basis of technical scheme of the present invention, done by those skilled in the art all belong to protection scope of the present invention.
