Description
Technical field
The utility model is related to electroacoustic switch technology field, more particularly, to a kind of water proof type sound-producing device and ear
Machine.
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 be led to
Cross the operatic tunes volume of the operatic tunes after loudspeaker or let out acoustic aperture debugging to the output of preferably low frequency.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, cause earphone to fail.
In prior art designs, be that the operatic tunes lets out the design of acoustic aperture and carrys out expansion low-frequency after loudspeaker, let out acoustic aperture need it is unobstructed and
With higher Air permenbility.But due to the waterproof material Air permenbility of IPX7 it is very low (be essentially airtight type).It is thus impossible to
Satisfaction lets out two conditions required by acoustic aperture：One is unobstructed；Two is to have high Air permenbility, so as to cause low-frequency effect poor.Such as
Fruit lifts low-frequency effect only by way of the volume of the operatic tunes after increase, then can cause two problems：One is that small product size increases
Greatly, so as to product seems heavy, the aesthetic property of product is destroyed；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 afterwards the temperature in the operatic tunes steeply rises, particularly end user
When using aboard or on plateau, easily by being destroyed into vibrating diaphragm, so as to cause 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,
The operatic tunes has shared the inner chamber body of product after loudspeaker, cause the acoustical signal of sender or loudspeaker after loudspeaker vibration signal can easily by
Microphone in product is received, and causes the problem of echo serious.
