Description
Technical field
The present invention relates to electroacoustic switch technology field, more particularly, to a kind of water proof type sound-producing device and earphone.
Background technology
Existing water proof type verbal system is lived on the premise of waterproof in satisfaction, i.e. IPX4 classification of waterproof typically can lead to
After crossing loudspeaker the operatic tunes volume of the operatic tunes or let out acoustic aperture debug preferably low frequency output.But this species water proof type earphone is in accident
After falling in water or being immersed in the water, its function can be destroyed, and also or produce dangerous, leads to earphone to lose efficacy.
In prior art designs, be that the operatic tunes is let out the design of acoustic aperture and carried out expansion low-frequency after loudspeaker, let out acoustic aperture need unobstructed and
There is higher Air permenbility.But due to the waterproof material Air permenbility of IPX7 all very low (being all essentially airtight type).It is thus impossible to
Meet two conditions let out required by acoustic aperture:One is unobstructed;Two are intended to high Air permenbility, thus causing low-frequency effect poor.As
Fruit to lift low-frequency effect, then can lead to two problems only by way of the volume of the operatic tunes after increase:One is that small product size increases
Greatly, thus product seems heavy, destroy the aesthetic property of product;Two be earphone class product during use, due to speaker voice coil
Drive is shaken vibration of membrane, operatic tunes air after drastically compressing so that the temperature in the rear operatic tunes steeply rises, particularly end user
When using aboard or on plateau, easily by becoming vibrating diaphragm to be destroyed, thus leading to damage of product.
The existing verbal system that can meet IPX7 classification of waterproof, in order to effectively increase the volume of the rear operatic tunes of loudspeaker,
After loudspeaker, the operatic tunes has shared the inner chamber body of product, cause the acoustical signal of sender or loudspeaker after loudspeaker vibration signal can easily by
Microphone in product receives, and cause echo problem serious.
