Abstract
The present invention provides a kind of loudspeaker of dustproof and waterproof, including upper lid, base, piezo, the both sides of the upper lid are provided with and buckle, described buckling detachably is connected with base, the upper lid is provided with several vocal holes, Air Filter is provided with below the upper lid, the lower section connection piezo of the Air Filter, the piezo is arranged on the top of base.Upper lid the beneficial effects of the invention are as follows loudspeaker is provided with several vocal holes, the diameter very little of its vocal hole, avoid water and dust from entering into piezo, Air Filter is arranged between the upper lid of loudspeaker and piezo, again ensure that the upper dust that will not fall in piezo.
Description
Technical field
The invention belongs to loudspeaker field, more particularly, to a kind of loudspeaker of dustproof and waterproof.
Background technology
Loudspeaker is a kind of electroacoustic converting member, and sound electric signal is converted into sound by it.In general,
The either loudspeaker of which kind of particular type, including base, upper lid and between base and upper lid
Piezo, offers multiple vocal holes on upper lid, sound electric signal can transform into the vibration of piezo,
Sound is outwards propagated by air dielectric again.The loudspeaker for occurring on the market at present is using certain hour
Afterwards, can have dust in piezo, the tonequality and service life of loudspeaker can be directly affected；Some water,
The liquid such as tea, coffee are penetrated into loudspeaker, although loudspeaker on the market has certain water-proof function
Can solve the above problems, but its waterproof effect is not notable, still loudspeaker can be caused normal
Use.
The content of the invention
It is an object of the invention to provide a kind of simple structure, it is simple to operate, given birth to dust-proof and waterproof effect
Produce the loudspeaker of the dustproof and waterproof of efficiency high.
The technical scheme is that：A kind of loudspeaker of dustproof and waterproof, including upper lid, base, buzzing
Piece, the both sides of the upper lid are provided with and buckle, and described buckling detachably is connected with base, on the upper lid
Several vocal holes are provided with, Air Filter, the lower section connection honeybee of the Air Filter are provided with below the upper lid
Ring piece, the piezo is arranged on the top of base.
Further, the vocal hole is circular port, a diameter of 0.1-0.2mm.
The present invention has the advantages and positive effects that：Due to using above-mentioned technical proposal, loudspeaker it is upper
Cover and be provided with several vocal holes, the diameter very little of its vocal hole, it is to avoid water and dust enter into piezo
In, Air Filter is arranged between the upper lid of loudspeaker and piezo, is again ensured that and will not fall in piezo
Dust.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：
1st, upper lid 2, base 3, piezo
4th, 5, vocal hole 6, Air Filter is buckled
Specific embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of loudspeaker of dustproof and waterproof of the invention, including upper lid 1, base 2, honeybee
Ring piece 3, the both sides of the upper lid 1 are provided with and buckle 4, described to buckle 4 and be detachably connected with base 2,
The upper lid 1 is provided with several vocal holes 5, and the lower section of the upper lid 1 is provided with Air Filter 6, described
The lower section connection piezo 3 of Air Filter 6, the piezo 3 is arranged on the top of base 2.
The vocal hole 5 is circular port, a diameter of 0.1-0.2mm.
The course of work of this example：The upper lid 1 of loudspeaker is provided with several vocal holes 5, its vocal hole 5
Diameter very little, the diameter of vocal hole 5 is less than 0.2mm, and water droplet will not be penetrated because of self gravitation and is less than
The cavity of 0.2mm rests on lid outer layer, effectively avoids water droplet and dust from entering into piezo 3,
Air Filter 6 is arranged between the upper lid 1 of loudspeaker and piezo 3, and again ensuring that will not in piezo 3
Fall upper dust, can make loudspeaker normal operation, does not interfere with tonequality.
One embodiment of the present of invention has been described in detail above, but the content is only of the invention
Preferred embodiment, it is impossible to be considered as limiting practical range of the invention.It is all according to the present patent application scope
The impartial change made and improvement etc., all should still belong within patent covering scope of the invention.
