Abstract

The utility model provides a dust-proof net fixing structure of a speaker. In the technical proposal, an opening at the upper end of a speaker shell is provided with at least one support plate crossing on the opening; the two ends of the support plate are fixedly arranged on the two ends of the peripheral edge of the shell; and a dust-proof net of the speaker is fixedly arranged on the peripheral edge of the shell and covered on the support plate and the opening. Therefore, with the support and blockage of the support plate, the utility model can resolve the problem that the center of the dust-proof net can be impacted under the external force to inwards cling against the vibration diaphragm of the speaker to cause the normal operation of the vibration diaphragm.

Description

A kind of Air Filter fixed structure of loud speaker

Technical field

The utility model relates to a kind of Air Filter fixed structure of loud speaker, relates in particular to a kind of Air Filter that prevents loud speaker and is posted by Air Filter fixed structure on its vibrating diaphragm.

Background technology

General traditional loud speaker (for example: loudspeaker, acoustical generator, buzzer etc.) mainly utilizes the combination of magnetite, vibrating diaphragm and voice coil loudspeaker voice coil, but via the resistance of modulation, produces suitable resistance, so that after electric current passes through, produce sound.

As shown in Figure 1, it is the stereogram of generally existing loud speaker, and described loud speaker 10 promptly utilizes the visible vibrating diaphragm 11 of front end face, and the combination of voice coil loudspeaker voice coil 13, after electric connection line 14 is by current lead-through, can sound; Fig. 2 is the side sectional view of Fig. 1 loud speaker 10, as shown in Figure 2, described loud speaker 10 is the pedestals that formed by the set U sections 12 of a housing 18 and housing 18 central authorities, in the space of described U sections 12 indents, carry and adorn a magnetite 15, magnetite 15 tops are connected with an electrode slice 16; And loud speaker 10 set voice coil loudspeaker voice coils 13 center on the periphery that is formed at electrode slice 16 and

magnetite

15, and 11 of vibrating diaphragms are overlying on upper end in the housing 18; Again, housing 18 outside root edge chosen places also are formed with a terminal board 17, and terminal board 17 1 ends and voice coil loudspeaker voice coil 13 are electrically connected, and then are provided with two electric connection lines 14 on the other end, be electrically connected for electronic installation, and received the sounding electric current of described electronic installation with periphery; Described housing 18 upper end peripheries 181 also are provided with an Air Filter 19, and the opening 182 of described Air Filter 19 covering shells 18 upper ends is for preventing that dust, particulate from being entered in the housing 18 by opening 182.After the sounding current lead-through of electronic installation, by the difference of voice coil loudspeaker voice coil 13 resistive impedance, cooperate the effect of vibrating diaphragm 11, can produce sound.

But, the Air Filter 19 of described existing loud speaker 10 only 191 adheres on housing 18 peripheries 181 on every side by it, central authorities 192 without any support, add that Air Filter 19 is nylon cloth material soft full of elasticity, cause Air Filter 19 to be subjected to external force (as: wind, neglectful collision etc.) collision easily and central authorities 192 inwardly are posted by on the vibrating diaphragm 11, make the vibrating diaphragm 11 can't normal operation (vibration), and can't produce normal sounding, very not convenient.

Summary of the invention

The inventor is because the shortcoming of aforementioned prior art, be engaged in the manufacturing experience and the technology accumulation of various loud speakers according to it, method at the various solutions of the concentrated research of above-mentioned shortcoming, after through constantly research, experiment and improvement, finally development and Design goes out the utility model of the Air Filter fixed structure of a kind of brand-new loud speaker of the present utility model, in the hope of the shortcoming that prior art produced of forgoing.

A purpose of the present utility model is to provide a kind of Air Filter fixed structure of loud speaker, can prevent that with order the Air Filter of described loud speaker is posted by on its vibrating diaphragm.
