Fig. 2 is the structural representation of the electronic equipment of electronic equipment embodiment of the present invention.
Specific embodiment
Refering to Fig. 1, waterproof acoustical device embodiment of the present invention includes：Housing 11, acoustical device body 12.
The acoustical device body 12 is located in the housing 11.The opposite both sides of wherein described acoustical device body 12 with
The housing 11 is respectively enclosed to front sound chamber 13 with rear sound chamber 14.The corresponding part of the housing 11 in the front sound chamber 13 is provided with out
Sound hole 111, sender 111 described in the front Jing of sound chamber 13 is in communication with the outside.The rear sound chamber 14 passes through one or more passages
15 connections are extraneous.In the passage 15, i.e., it is provided with first in described passage 15 or between the passage 15 and the rear sound chamber 14
Waterproof membrane 16.
Optionally, the rear sound chamber 14 connects the external world by 1-100 passage 15.10-80 passage 15 is chosen as, it is optional
For 30-60 passage 15,40-50 passage 15 is chosen as.Can be in all passages 15, i.e., inside described passage 15 all
It is provided with the first waterproof membrane 16.Can also the part passage 15 be internally provided with the first waterproof membrane 16, passage described in another part
The first waterproof membrane 16 is provided between 15 and the rear sound chamber 14.Such as described rear sound chamber 14 connects the external world by 2 passages 15, its
In be provided with the first waterproof membrane 16 in 1 inside of the passage 15, is provided between another 1 passage 15 and the rear sound chamber 14
One waterproof membrane 16.
In the actual process of waterproof of the acoustical device, because sender 111 described in the front Jing of sound chamber 13 connects with extraneous
It is logical, therefore when the acoustical device 1 is placed in water, the front sound chamber 13 can intake, or even water can be full of, now water can be oppressed
The acoustical device 1 produces pressure, and when the depth of water that the acoustical device 1 is in is deeper, the pressure being subject to is bigger.The rear sound chamber
14 connect the external world by one or more passages 15, there is the gases such as air in the rear sound chamber 14 and the passage 15, work as water
The one end being in communication with the outside from the passage 15 is entered in the passage 15, it will the gas such as air in the compression passage 15
Body is so as to compressing the gases such as the air in the rear sound chamber 14.The water in now described front sound chamber 13 is produced to the acoustical device 1
Pressure, with the air in the rear sound chamber 14 compressed and to the acoustical device 1 produce pressure mutually balance so that
The pressure of the both sides of the acoustical device 1 cancels out each other, it is to avoid the acoustical device 1 is subject to unbalanced pressure and caused damage
It is bad, while being provided with the first waterproof membrane 16 in the passage 15 or between the passage 15 and the rear sound chamber 14, can avoid
Water enters into the rear sound chamber 14 such that it is able to strengthen the waterproof effect of the acoustical device 1.
Due to position consistency or unanimous on the whole of the front sound chamber 13 with the passage 15 in water, i.e., no matter how deep water is,
The pressure that water is caused to the front sound chamber 13 is always equal to the pressure that the passage 15 or the rear sound chamber 14 are caused with water
, in theory anti-water depth is no maximum.But the effective depth of the acoustical device waterproof depends on the body of the passage 15
The long-pending and described rear volume of sound chamber 14, and the proportionate relationship between the front volume of sound chamber 13, in this embodiment, to the passage
Proportionate relationship between 15 volume and the rear volume of sound chamber 14, with the front volume of sound chamber 13 is not construed as limiting, can be with root
The volume and the rear volume of sound chamber 14 of the passage 15 are determined according to the effective anti-water depth for needing, with the front sound chamber 13
Volume.
In the present embodiment, the front sound chamber 13 and the rear sound chamber 14 are isolations, and liquid does not circulate.
In the present embodiment, the position of the sender 111 is opened up in the corresponding part of the housing 11 in the front sound chamber 13
Put and be not construed as limiting, the quantity of the sender 111 is not construed as limiting.
Optionally, the passage 15 at least has a bending section 151.I.e. each described passage 15 has at least one institute
Bending section 151 is stated, each described passage 15 is chosen as with the 1-100 bending section 151, each described passage 15 is chosen as
With the 5-85 bending section 151,15-70 bending section 151 is chosen as, is chosen as 20-50 bending section 151, be chosen as
30-40 bending section 151.When the quantity of the passage 15 is at least 2, the bending section 151 that all passage 15 has
Quantity can with identical, can part it is identical, can be all different.
