The invention discloses one kind from pressure release water-proof loudspeaker, including casing, casing is internally provided with rear sound chamber and preceding sound chamber, sound chamber is that hermetic type or bottom offer and let out pressure hole afterwards, the inside of casing is fixedly installed with loudspeaker support, it is fixedly installed with magnetic circuit of loudspeaker on the downside of loudspeaker support, loudspeaker coil is provided on the outside of magnetic circuit of loudspeaker, is provided with the diaphragm of loudspeaker on the upside of loudspeaker coil and bracket.The present invention in vibrating diaphragm and sounding film surface by opening up from relief hole; waterproof ventilated membrane is attached from pressure release hole surface; when machine is persistently overheating or rapidly heats up; sound chamber air expands afterwards, and pressure increases, and rear sound chamber lets out pressure hole air leakage amount and deficiency occurs; what is opened up from the sounding film surface of loudspeaker special designing carries out releasing pressure automatically from relief hole; the gas pressure intensity generated by machine operation heat is eliminated, the normal equilibrium of speaker vibration system is protected, does not change the original electroacoustic property of loudspeaker.
Description
Technical field
The invention belongs to speaker technology fields, are specifically related to a kind of from pressure release water-proof loudspeaker.
Background technique
Loudspeaker is a kind of energy transducer for electric signal being changed into acoustical signal, the shadow of the performance superiority and inferiority of loudspeaker to sound quality
Sound is very big.Loudspeaker is a most weak device in stereo set, and for acoustics, it is one most heavy again
The component wanted.Loudspeaker it is many kinds of.Audio electric energy makes its cone or diaphragm vibration by electromagnetism, piezoelectricity or electrostatic effect
And resonance is generated with the air of surrounding and is made a sound.
There are two types of the rear sound chambers of conventional loudspeakers, a kind of rear sound chamber for letting out pressure hole for band, and one kind is sound chamber after hermetic type,
The loudspeaker that band lets out sound chamber after pressure hole generates heat at work, and rear sound cavity space gas starts thermal expansion, generates atmospheric pressure, pressure
Value is lasting to be increased, and when rear sound chamber is when letting out pressure hole capacity deficiency, expanding gas starts to oppress the diaphragm of loudspeaker, causes vibrating diaphragm
Vibration is uneven, generates vibration sound and small sound phenomenon, and the above-mentioned phenomenon of loudspeaker appearance of sound chamber becomes apparent after hermetic type.
Summary of the invention
The present invention mainly solves technical problem present in the above-mentioned prior art, provides a kind of from pressure release waterproof loudspeaking
Device.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: a kind of from the anti-bigcatkin willow of pressure release
Sound device, including casing, the casing are internally provided with rear sound chamber and preceding sound chamber, and the rear sound chamber is that hermetic type or bottom open up
Pressure hole is let out, the inside of the casing is fixedly installed with loudspeaker support, is fixedly installed on the downside of the loudspeaker support
Magnetic circuit of loudspeaker is provided with loudspeaker coil on the outside of the magnetic circuit of loudspeaker, sets on the upside of the loudspeaker coil and bracket
It is equipped with the diaphragm of loudspeaker, the upside of the diaphragm of loudspeaker is arranged sounding film, and the surface of the diaphragm of loudspeaker and sounding film is opened
Equipped with from relief hole.
Preferably, being provided with waterproof ventilated membrane on the upside of the sounding film.
Preferably, the sounding film, which uses, has the frivolous sheet material of rigidity.
The invention has the benefit that
1, the present invention attaches waterproof and breathable from pressure release hole surface by opening up in vibrating diaphragm and sounding film surface from relief hole
Film, when machine is persistently overheating or rapidly heats up, rear sound chamber air expansion, pressure increases, and rear sound chamber lets out pressure hole air leakage amount
There is deficiency, what is opened up from the sounding film surface of loudspeaker special designing carries out releasing pressure automatically from relief hole, eliminates because of machine work
The gas pressure intensity for making heat generation, protects the normal equilibrium of speaker vibration system, and the original electroacoustic for not changing loudspeaker is special
Property.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: one kind is from pressure release water-proof loudspeaker, as shown in Figure 1-3, include casing 1, after being internally provided with of casing 1
Sound chamber 5 and preceding sound chamber 4, rear sound chamber 5 are that hermetic type or bottom offer and let out pressure hole 2, and the inside of casing 1 is fixedly installed with loudspeaking
Device bracket 6, the downside of loudspeaker support 6 are fixedly installed with magnetic circuit of loudspeaker 3, and the outside of magnetic circuit of loudspeaker 3 is provided with loudspeaker
The upside of coil 8, loudspeaker coil 8 and bracket 6 is provided with the diaphragm of loudspeaker 7, and sounding film 9 is arranged in the upside of the diaphragm of loudspeaker 7,
Sounding film 9 is using with the frivolous sheet material of rigidity, such as PEI, PEN, PET, PI, aluminium foil, copper platinum rigid sheet, sounding film 9
Upside be provided with waterproof ventilated membrane 11, the surface of the diaphragm of loudspeaker 7 and sounding film 9 is offered from relief hole 10, loudspeaker vibration
It is single or multiple that film 7 and 9 surface of sounding film opened up have from relief hole 10, can arrange on demand, generate and continue inside machine
Heat, air generate expansion, are discharged automatically from from relief hole 10, which eliminates the gas pressure generated by speaker operation heat
By force, the normal equilibrium of speaker vibration system is protected, does not change the original electroacoustic property of loudspeaker.
Practical principle of the invention: the present invention by opening up in the diaphragm of loudspeaker 7 and 9 surface of sounding film from relief hole 10,
Loudspeaker attaches waterproof ventilated membrane 11 from 10 surface of relief hole, when machine is persistently overheating or rapidly heats up, air in rear sound chamber 5
Expansion, pressure increase, when letting out 2 air leakage amount of pressure hole appearance deficiency of rear sound chamber 5, from 9 table of sounding film of 3 special designing of loudspeaker
What face opened up carries out releasing pressure automatically from relief hole 10, eliminates the gas pressure intensity generated by machine operation heat, protection loudspeaker vibration
The normal equilibrium of dynamic system, does not change the original electroacoustic property of loudspeaker.
Finally it is pointed out that above embodiments are only the more representational examples of the present invention.It is clear that the invention is not restricted to
Above-described embodiment, acceptable there are many deformations.Any letter to the above embodiments according to the technical essence of the invention
Single modification, equivalent variations and modification, are considered as belonging to the scope of protection of the present invention.
