Embodiment
In order to feature place of the present invention more can be understood, the invention provides a preferred embodiment and coordinate accompanying drawing to be described as follows, please refer to Fig. 1, waterproof membrane 10 is arranged on a location division 21 of mount pad 20 by the present invention, and mount pad 20 can be assembled into one with a shell body 30 with audio output device, and in shell body 30, be provided with a loud speaker (figure does not illustrate).Aforementioned sound output equipment can be the electronic equipments such as mobile phone, flat board or notebook computer, or the electroacoustic equipment such as earphone or loudspeaker.
Waterproof membrane 10 is made for waterproof material, such as polyethylene terephthalate (PET), PEN (PEN) or PolyEtherImide (PEI), and waterproof membrane 10 has outer surface 13 and an inner surface 14, wherein, outer surface 13 is towards a sound hole 31 of shell body 30, and inner surface 14 is towards the source of sound (figure does not illustrate) in audio output device.
In addition, waterproof membrane 10 can be identical with the cross sectional shape of the vibrating diaphragm of aforementioned speakers, include a central portion 11 is probably positioned at waterproof membrane 10 central authorities in tabular, and cross section is curved and around the resilient projection 12 being connected to central portion 11 outer peripheral edges, simultaneously, the outer peripheral edges of resilient projection 12 are connected to location division 21, and resilient projection 12 is convex in mount pad 20, and namely resilient projection 12 protrudes the plane P that inner surface 13 extends to form in central portion 11.
