Description
Technical field
The utility model relates to a kind of Cellphone Accessories, especially a kind of mobile phone water-proof loudspeaker.
Background technology
In the process of routine use mobile phone, inevitably easily make mobile phone touch water (as drench with rain or drop as in water).Mobile phone sounding component is owing to belonging to accurate easily worn part, breaks down after very easily meeting water.So need to carry out waterproofing design to the loud speaker of mobile phone.Chinese utility model patent CN202738091U discloses a kind of water-proof loudspeaker structure, has realized the water-proof function of loud speaker.But this waterproof construction is that the form by directly sounding component being isolated from the outside realizes waterproof effect, this has just affected the sounding effect of loud speaker.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mobile phone water-proof loudspeaker, can solve the deficiencies in the prior art, can automatically realize according to the size of inflow the switching of multi-form waterproof construction, hour can ensure the voice quality of loud speaker at inflow, in the time that inflow is larger, can ensure the security seal waterproof of loud speaker.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of mobile phone water-proof loudspeaker, comprise substrate, on substrate, be provided with voice coil loudspeaker voice coil, described voice coil loudspeaker voice coil top is fixed with sounding board, in sounding board, be provided with cellular cavity, sounding board top is connected with top board by pole, the outward flange of substrate is provided with the first plate washer, the inner side of the first plate washer is provided with the second plate washer, the height of the first plate washer is greater than the height of the second plate washer, the outward flange of top board is provided with swash plate, swash plate is arranged between the first plate washer and the second plate washer, the bottom surface of swash plate is provided with rubber sealant, on substrate, be provided with osculum, osculum is between the first plate washer and the second plate washer, osculum top is provided with uncovered, osculum bottom is provided with spiral capillary, the sidewall of spiral capillary is provided with side opening, the interface of side opening and spiral capillary is provided with rubber membrane, in side opening, be provided with pin, one end of pin is connected with rubber membrane, between substrate and voice coil loudspeaker voice coil, be provided with portable plate, voice coil loudspeaker voice coil is fixedly connected with portable plate, portable plate is flexibly connected with substrate, pin is between portable plate and substrate, pin top is provided with breach, portable plate bottom is provided with the projection matching with breach.
As preferably, described pole and top board inside are provided with the cavity of perforation, are filled with wire in cavity.
As preferably, described the first plate washer is 5: 1～3: 2 with the ratio of the height of the second plate washer.
As preferably, the substrate surface between described the first plate washer and the second plate washer is provided with the groove matching with rubber sealant.
The beneficial effect that adopts technique scheme to bring is: the utility model is in the time of normal use, by the space between the first baffle plate and the second plate washer, voice coil loudspeaker voice coil is directly communicated with the external world, this has just solved that existing water-proof loudspeaker directly seals voice coil loudspeaker voice coil and the problem of the sounding effect variation brought.Meanwhile, sounding board and pole, top board with cavity have formed a set of sound wave bang path, can reduce the attenuation rate that sound wave transmits directly over voice coil loudspeaker voice coil.When there being a small amount of water to enter after loud speaker, no matter drop on the inner side of top board or the first plate washer, all can fall into the position between the first plate washer and the second plate washer in the guiding of swash plate, and discharge by osculum.In the time that the water yield increases, the inflow of osculum increases, the cooperation of uncovered and spiral capillary has played to current mobile the effect of accelerating flow velocity, in the time that the current centrifugal force in spiral capillary increases to the threshold value of pin displacement, pin produces displacement, and projection is inserted in breach, portable plate moves down, top board is moved down simultaneously, and the rubber sealant of swash plate contacts with groove sealing, makes voice coil loudspeaker voice coil position and the external world realize seal isolation.This has just realized loud speaker and has automatically changed waterproof construction by the size of inflow, has met the normal use under time water yield simultaneously, has also avoided the infringement of big yield to inside loudspeakers.
