Description
Technical field
The utility model relates to a kind of loud speaker and uses the electronic product of this loud speaker.
Background technology
In recent years, along with the develop rapidly in electronic product markets such as mobile phone, notebook computer, a large amount of loud speakers are installed in electronic product inside and use widely.For needs to the loud speaker sounding, general on electronic product casing and the position of internal loudspeaker correspondence hole is set, but general electronic products all requires to have the function of waterproof at present, need prevent that moisture from entering electronic product inside by the sound hole on the electronic product casing.In order to address this is that, general design now mainly contains two kinds in the industry:
1, by on the shell of loud speaker and electronic product sound hole position contacting screen cloth is set, screen cloth perhaps is set at electronic product sound hole place;
2, by paste waterproofing membrane (being generally plastic material makes) on the shell of loud speaker and electronic product sound hole position contacting.
First kind of mode, if screen cloth is too loose, then waterproof effect is bad, for example it is submerged in the deep water, then be difficult to assurance and do not enter moisture, if screen cloth is too dense, perhaps utilize some hydrophobic materials to make, cause acoustic resistance excessive easily, to the acoustical behavior generation harmful effect of loud speaker; And the second way, waterproofing membrane only is to reach water-proof function, can not shake, and is more obvious for the acoustical behavior influence of loud speaker.
So, need seek a kind ofly can reach waterproof effect preferably, and not sacrifice the scheme of acoustical behavior.
The utility model content
Technical problem to be solved in the utility model provides a kind of waterproof electronic product that acoustical behavior just can reach the waterproof loud speaker of good waterproof effect and use this loud speaker of not sacrificing.
For solving the problems of the technologies described above, the utility model provides a kind of waterproof loud speaker, the waterproof loud speaker, the shell that comprises an end opening, be installed in the phonation unit of described enclosure, the vibrating diaphragm of described phonation unit is positioned at the openend of described shell, around the bearing of described vibrating diaphragm outer surface fixed frame is installed, the openend of described fixed frame is equipped with second vibrating diaphragm that can stop water to enter, and described shell, fixed frame and second vibrating diaphragm constitute the water-proof sealing cavity; Second vibrating diaphragm has better elastic, and it is provided with and can prevents that moisture from entering inside loudspeakers, and the voice signal that phonation unit can be produced through the transfer of vibration of second vibrating diaphragm to extraneous, do not sacrifice acoustical behavior.
The improvement of the technical program is that described second vibrating diaphragm is the plastics vibrating diaphragm.Use plastics vibrating diaphragm damping characteristic fine, submissive nature on the sense of hearing uses low order, simple partial device just can reach good audio frequency effect.
The further improvement of the technical program is that the described second vibrating diaphragm outer ledge is pasted with annular glue-line.This design also can be so that the installation facility of waterproof loud speaker in installing and using, can directly be installed in the electronic product casing inboard with the stickup of waterproof loud speaker.
The further improvement of the technical program is that the fixed frame between described vibrating diaphragm and described second vibrating diaphragm is provided with the phonation unit protecgulum, and the vibrating diaphragm of described protecgulum and described phonation unit and described second vibrating diaphragm do not contact, and described protecgulum is provided with the hole some.The phonation unit protecgulum in this programme and the protecgulum of ventional loudspeakers structure are similar, has the sound hole that is used for speaking, and can paste various acoustics parts in the above, this design can guarantee the vibration freedom of second vibrating diaphragm, and when the waterproof loud speaker bore the hydraulic pressure moderate finite deformation, protecgulum also can be supported second vibrating diaphragm, prevent that the distortion of second vibrating diaphragm is excessive even destroyed.
The further improvement of technique scheme is: described second vibrating diaphragm is a flat shape.The planar design of second vibrating diaphragm can avoid producing undesired deformation, thereby causes acoustical behavior to change.
The utility model also provides the waterproof of using above-mentioned loud speaker electronic product, comprise an electronic product casing that has hole, described sound hole installed inside has phonation unit, bearing around described phonation unit vibrating diaphragm outer surface is equipped with fixed frame, the openend of described fixed frame is equipped with second vibrating diaphragm that can stop water to enter, described second vibrating diaphragm is fixedly mounted on described sound inboard, hole by jockey, the shell of described phonation unit, the fixed frame and second vibrating diaphragm constitute the water-proof sealing cavity, and have oscillation space between described second vibrating diaphragm and the described electronic product casing.With respect to the ordinary electronic product, the electronic product of this programme also is equipped with one second vibrating diaphragm between phonation unit harmony hole, can finish the function of waterproof preferably, and second vibrating diaphragm transmission voice signal, can reach sound effect preferably.
The improvement of the technical program is: described jockey is the ring-type adhesive layer.Make things convenient for the installation of waterproof loud speaker.
The further improvement of the technical program is: described second vibrating diaphragm is installed in described sound inboard, hole in advance.The effect that this designing institute can reach is consistent with the effect that second vibrating diaphragm is installed on the phonation unit, and the main distinction is the technology difference, changes according to the needs of actual production convenience.
The further improvement of the technical program is: described phonation unit is the moving-coil type phonation unit.
Owing to adopted technique scheme, the beneficial effects of the utility model are: waterproof loud speaker and use the waterproof electronic product structure of this loud speaker very simple, with low cost can reach waterproof effect preferably, and not sacrifice acoustical behavior.
