Background technology
Speaker, also known as " loudspeaker ", is a kind of very conventional electro-acoustic transducer device, in the electronic electric equipment of sounding
It can be seen.Speaker is the electroacoustic transducer that can be converted the electrical signal to acoustical signal and go in being radiated air.Traditional
Speaker is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In each type
In speaker, with it is most, be most widely dynamic speaker, be also called coil-moving speaker.
After speaker use time length, many dusts on its diaphragm surface, can be stained with, existing speaker only installs
One dustproof membrane, can only prevent dust from entering into inside loudspeakers, and can not prevent dust from adhering on vibrating diaphragm, dust-proof effect
Difference, not only affects speaker attractive in appearance, and can increase the work burden of people, and using effect is bad.
Utility model content
The purpose of this utility model is to provide a kind of dust-proof speaker, existing with solve to propose in above-mentioned background technology
Speaker dust-proof effect difference problem.
For achieving the above object, this utility model provides following technical scheme：A kind of dust-proof speaker, including speaker master
Body, rotary shaft, framework and drive magnet, are provided with dust cap above the speaker body, and the lower section of dust cap is fixed
Dust cap is installed, dust-proof blade is installed on the dust cap, and dust cap bottom is provided with fixed rubber circle, the rotary shaft
Left end is connected with gear, and rotary shaft right-hand member is connected with dust-proof blade, and the both sides of the dust cap are provided with conical diaphragm, described
Framework is connected with conical diaphragm by vibrating diaphragm ring, is provided with voice coil loudspeaker voice coil between the drive magnet, the voice coil loudspeaker voice coil and framework it
Between be installed with and determine core piece.
Preferably, the dust cap is made up of upper dust cap and lower dust cap, and between connected mode be nut connection.
Preferably, the dust-proof blade is rotatable device, and dust-proof blade rotation angle range is 0-180 °.
Preferably, the dust-proof blade number is four, and it is generally circular in shape to combine.
Preferably, the number of gears is four, and mutually ratcheting between gear.
Compared with prior art, the beneficial effects of the utility model are：One dust cap is installed on the dust-proof speaker,
The dust in air can be effectively prevented to adhere on conical diaphragm, when needing using speaker, by rotating dust-proof leaf
Piece, so that it may so that dust cap is opened, when using, by rotating dust-proof blade, so that it may so that dust cap closes,
Do not affect the use of speaker, not only good dustproof effect, and effectively alleviate the work of people to bear on the basis of dust-proof
Load, it is mutually ratcheting between gear, by rotating a dust-proof blade, it is possible to drive other dust-proof blades to rotate, using effect
It is really good.
