Description
Technical field
The utility model is related to a kind of audio frequency apparatus, especially a kind of mobile phone speaker cavity.
Background technology
The applicant is in application number：201520637510.X, title：A kind of speaker chamber with micropore and including the chamber
Loudspeaker, the day for announcing：2015.12.09 a kind of speaker chamber with micropore is disclosed in utility model, including back cavity is with before
Chamber, the ante-chamber plays a supportive role, for installing on the right side of loudspeaker body, ante-chamber provided with the structure for installing loudspeaker body, institute
State back cavity to seal with ante-chamber, form the micropore being provided with the left of complete cavity space, the ante-chamber for radiating；The micropore is upper
Small conical structure under big；The cone angle of the conical structure is 80 ~ 100o；The micropore also includes upper small in conical structure bottom
The through hole of big cylinder hierarchic structure down, the upper diameter of cylinder ladder is identical with the base diameter of circular cone；Also include being used to adjust
The adjustable sound paper of inside cavity and outer gas stream amount is saved, the adjustable sound paper is arranged on micro-hole top, covers miniature bore region；It is described
Ante-chamber is provided with the groove for installing adjustable sound paper；A kind of loudspeaker, including loudspeaker body and speaker chamber, the speaker chambers
Body is any of the above-described speaker chamber.After micropore being opened on speaker chamber ante-chamber, good heat dissipation effect, loudspeaker this body running temperature
Spend low, long service life；Sound wave is adjusted adjustable sound paper simultaneously, it is to avoid low-frequency distortion caused by cavity perforate is extremely existing
As.But the mobile phone cavity water resistance is bad.
Utility model content
In order to solve the deficiency of prior art presence, the utility model provides a kind of using air equalizer opening design.
A kind of waterproof mobile phone sound chamber in the utility model, including cavity, waterproof ventilated membrane and loudspeaker, waterproof ventilated membrane
The air-vent less than hydrone diameter is provided with, the cavity upper right corner is provided with dividing plate provided with passage, middle part；Dividing plate is formed with cavity
The sound chamber of closing, loudspeaker is arranged on the left of dividing plate, and loudspeaker pronunciation is face-up；It is provided with the right side of dividing plate on balance pipe, balance pipe
Portion is provided with vent notch, waterproof ventilated membrane covering balance pipe outlet face provided with the groove of waterproof ventilated membrane, middle part is placed.By anti-
Water ventilated membrane prevents that steam from entering in sound chamber.
Preferably, 0.1 ~ 0.15mm of depth of groove.Low cost, is easy to processing.
Preferably, also including mylar film, balance pipe bottom is stayed provided with the boss for placing mylar film between mylar film and dividing plate
There is gap.Airflow direction between inside cavity air pressure and balance pipe is changed by mylar film, slows down air-flow, increase damping is kept away
Exempt from throughput at because of air equalizer opening excessive and dyeing is produced to loudspeaker tone color.
Preferably, dividing plate is provided with the micropore for radiating；The micropore is up big and down small conical structure；The circle
The cone angle of wimble structure is 80 ~ 100o；The micropore is logical also including up-small and down-big cylinder hierarchic structure in conical structure bottom
Hole, the upper diameter of cylinder ladder is identical with the base diameter of circular cone；Also include being used to adjust inside cavity and outer gas stream amount
Adjustable sound paper, the adjustable sound paper is arranged on micro-hole top, covers miniature bore region；Adjustable sound paper top is provided with waterproof ventilated membrane.
The temperature of loudspeaker body is substantially reduced by micropore heat radiation energy, extends the service life of loudspeaker.
The beneficial effects of the utility model：Prevent that steam from entering in sound chamber by waterproof ventilated membrane.
Brief description of the drawings
Fig. 1 is a kind of waterproof mobile phone audio cavity structure schematic diagram.
Marked in figure：1st, cavity, 2, loudspeaker, 3, waterproof ventilated membrane, 4, mylar film, 5, balance pipe, 6, sound chamber, 11, every
Plate, 21, loudspeaker pronunciation face.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but this should not be interpreted as of the present utility model
The scope of above-mentioned theme is only limitted to above-described embodiment.
As shown in figure 1, a kind of waterproof mobile phone sound chamber, including cavity 1, waterproof ventilated membrane 3, mylar film 4 and loudspeaker 2, prevent
Water ventilated membrane 3 is provided with the air-vent less than hydrone diameter, and the upper right corner of cavity 1 is provided with dividing plate 11 provided with passage, middle part；Every
Plate 11 and the sound chamber 6 of cavity formation closing, loudspeaker 2 are arranged on the left side of dividing plate 11, and loudspeaker pronunciation face 21 is upward；Dividing plate 11 is right
Side is provided with balance pipe 5, and the top of balance pipe 5 is provided with provided with the groove of waterproof ventilated membrane 3, middle part is placed provided with vent notch, bottom
The boss of mylar film 4 is placed, gap is left in the covering balance pipe 5 of waterproof ventilated membrane 3 outlet face between mylar film 4 and dividing plate 11.Pass through
Waterproof ventilated membrane 3 prevents that steam from entering in sound chamber 6, and the air-flow side between inside cavity air pressure and balance pipe is changed by mylar film
To slowing down air-flow, increase damping, it is to avoid because the throughput at air equalizer opening is excessive and produces dyeing to loudspeaker tone color.
Preferably, 0.1 ~ 0.15mm of depth of groove.Low cost, is easy to processing.
