Description
[technical field]
The utility model relates to a kind of microphone device, particularly relates to a kind of microphone device be used on portable type electronic product.
[background technology]
In the process of the portable type electronic product fast developments such as mobile phone, user is more and more stronger to the Functional Requirement of product, thus, and the development also corresponding quickening of microphone device.
The microphone device of correlation technique, it comprises the housing with cavity and the acoustical generator unit be installed on described housing.Because cavity is enclosed construction and cavity volume is smaller, so the resonance frequency of microphone device is high, cause the low frequency performance of microphone device poor, be difficult to play out simple and honest abundant bass, therefore, existing microphone device improves low frequency performance by filling sucting sound material therein, but, because sound-absorbing material volume is very little, be easy to enter into the inner operatic tunes of microphone device, affect the voice quality of microphone device.
Therefore, be necessary to provide a kind of new technical scheme to overcome above-mentioned defect in fact.
[utility model content]
The purpose of this utility model is to provide the good microphone device of a kind of low frequency performance, easily enters into the technical problem of the inner operatic tunes of microphone device for solving sound-absorbing material.
The purpose of this utility model is achieved in that
A kind of microphone device, it comprises housing, the phonation unit of assembly in this housing and the sound-absorbing material be filled in described inner chamber with inner chamber, this phonation unit comprises and the base plate of described lumen contact and the inside operatic tunes with this contacts baseplate, this phonation unit is provided with and runs through this base plate and the through hole being communicated with the inner operatic tunes of phonation unit and described inner chamber, this base plate is provided with and covers described through hole and breathable separator, and described separator is used for preventing described sound-absorbing material from entering into the inner operatic tunes of phonation unit.
Preferably, described separator is damping cloth.
Preferably, described separator is provided with multiple air-vent.
Preferably, described separator is bonded and fixed to described base plate.
Preferably, described microphone device comprises the magnetic circuit system with magnetic gap, and described magnetic gap is by this through hole and inner space.
Preferably, described housing is provided with phonate hole, and described phonation unit is spoken by this phonate hole.
Preferably, described housing comprises upper shell and the lower house with described upper shell assembly, and described phonate hole is arranged at this upper shell.
The utility model has the following advantages: microphone device of the present utility model not only low frequency performance is good, and the space availability ratio of microphone device inner chamber is high, and sound-absorbing material is not easy the inside operatic tunes entering into phonation unit.
[accompanying drawing explanation]
Fig. 1 is the three-dimensional exploded view of microphone device of the present utility model;
Fig. 2 is the cutaway view of microphone device shown in Fig. 1;
Fig. 3 is the stereogram after lower house separation in microphone device shown in Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
As illustrated in fig. 1 and 2, for the utility model provides a kind of microphone device 1, it comprises housing 10, the phonation unit 11 of assembly in this housing 10, the sound-absorbing material 12 be filled in described inner chamber 100, the pad 13 of assembly between phonation unit 11 and housing 10 and for realizing described phonation unit 11 and the extraneous conducting terminal 14 be electrically connected with inner chamber 100.
This phonation unit 11 comprises the base plate 110 contacted with described inner chamber 100 and the inside operatic tunes 111 contacted with this base plate 110, and this phonation unit 11 is provided with and runs through this base plate 110 and the through hole 112 being communicated with the inner operatic tunes 111 of phonation unit and described inner chamber 100.Described phonation unit 11 comprises the magnetic circuit system possessing magnetic gap 114, and in the present embodiment, this base plate 110 is the yokes in the magnetic circuit system of phonation unit 11, and it also can be the shell etc. of phonation unit 11.Phonation unit 11 comprises the vibrating diaphragm 113 for vibration sounding, the rear operatic tunes 1111 that vibrating diaphragm 113 is separated into the inner space 111 of phonation unit 11 the front operatic tunes 1110 and is communicated with magnetic gap 114, and described through hole 112 is communicated with this magnetic gap 114.The existence of this inner chamber 100, is equivalent to the rear operatic tunes 1111 increased in the inside operatic tunes 111 of described phonation unit 11, improves the low frequency performance of this phonation unit 11.
Again shown in composition graphs 3, this base plate 110 is provided with and covers described through hole 112 and breathable separator 115, and described separator 115 is bonded and fixed to described base plate 110.Described separator 115 enters into the inner operatic tunes of phonation unit for preventing described sound-absorbing material 12.This separator 115 is damping cloth, and preferably covers described through hole 112 completely.Ventilate to be beneficial between the inside operatic tunes 111 of described phonation unit 11 and described inner chamber 100, described separator 115 is provided with multiple air-vent 1150.
Described housing 10 is provided with phonate hole 101, and described phonation unit 11 is spoken by this phonate hole 101.Described housing 10 comprises upper shell 102 and the lower house 103 with the assembly of described upper shell 102, and described phonate hole 101 is arranged at this upper shell 102.
