Summary of the invention
The utility model technical problem to be solved is: provide a kind of computer headset to use unidirectional electret capacitor microphone; Simplify the structure; Solved because parts are many; Processing difficulties, the problem that efficiency of assembling is low, and solved the bad problem of sound effect consistency that existing acoustic resistance unit produces.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the computer headset is used unidirectional electret capacitor microphone; Comprise the external frame of enclosing and be installed on the capacitance component in the said external frame by wiring board and shell; On said shell, be provided with sound hole, on said wiring board, be provided with back of the body sound hole; Wherein:
Said capacitance component is electrically connected with said wiring board through the conduction grating ring, is provided with dead ring between said conduction grating ring and the said shell;
Said conduction grating ring comprises that ring body portion and one be located at the damping partition wall in the said ring body portion, on said damping partition wall, is provided with a through hole, on said through hole, is provided with adjustable sound paper.
As a kind of optimized technical scheme, said capacitance component comprises vibrating diaphragm, pad and the pole plate that corresponding said sound hole sets gradually, and said pole plate is electrically connected with wiring board through the conduction grating ring.
As a kind of optimized technical scheme, on said shell, be provided with the screen cloth that covers sound hole.
After having adopted technique scheme; The beneficial effect of the utility model is: the sound passage of the utility model is divided into two-way, and generally in the face of sound source, the sound passage of being passed through by sound hole is preceding path to the sound hole on the shell; Sound source directly arrives capacitance component by sound hole; The path is short, and damping is little, not decay or hysteresis when sound wave arrives capacitance component; Back of the body sound hole on the wiring board is generally back to sound source, and the sound passage that is got into by back of the body sound hole is the back sound travel, is located at the damping partition wall in the ring body portion because the conduction grating ring of the utility model comprises ring body portion and one; On the damping partition wall, be provided with a through hole, on through hole, be provided with adjustable sound paper, therefore; Sound source is got into by back of the body sound hole, through the damping partition wall in the conduction grating ring, owing to have only a through hole on the damping partition wall; So the sound of all back paths can only arrive capacitance component through the through hole on the damping partition wall; The adjustable sound paper that is provided with on the through hole has damping action to sound waves, and to the sound sharp wave of drawing up, improving the sound frequency characteristic has very effectively effect; It slackens and postpones the sound wave of back in the path; So just, enlarged preceding path and the difference of back path, strengthened the one-way of microphone, improved the consistency of sound effect the sound frequency response.In addition, the utility model is incorporated into the acoustic resistance unit in the traditional structure in the conduction grating ring, forms a part, has reduced difficulty of processing, has improved efficiency of assembling.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1. wiring board, 11. back of the body sound holes, 2. shell, 21. sound holes, 3. electronic devices and components, 41. vibrating diaphragms, 42. pads, 43. pole plates, 5. conduction grating ring, 51. ring body portions, 52. damping partition walls, 53. through holes, 54. adjustable sound papers, 6. dead ring, 7. screen cloth.
Embodiment
As shown in Figure 1, the computer headset is used unidirectional electret capacitor microphone, comprises the external frame of being enclosed by wiring board 1 and shell 2 and is installed on the capacitance component in this external frame, on shell 2, is provided with sound hole 21, on wiring board 1, is provided with back of the body sound hole 11.
Electronic devices and components 3 are installed on wiring board 1, comprise FET and electric capacity etc., be used for signal is handled and carried out impedance conversion.On shell 2, being provided with the screen cloth 7 that covers sound hole 21 is used to prevent dust.
In the present embodiment, capacitance component comprises vibrating diaphragm 41, pad 42 and the pole plate 43 that corresponding sound hole 21 sets gradually, and pole plate 43 is electrically connected with wiring board 1 through conduction grating ring 5, is provided with dead ring 6 between conduction grating ring 5 and the shell 2.
