Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone parts, in particular to an anti-wrinkle waterproof and sound-permeable membrane component. Background Art

[0002] In the prior art, speaker waterproof membrane is a polymer waterproof acoustic material, mainly used in various waterproof electronic products, such as waterproof mobile phones and waterproof cameras. It can prevent the speaker from short-circuiting due to water ingress while ensuring that the sound quality is not affected. Speaker waterproof membrane is a waterproof and sound-permeable membrane.

[0003] A mobile phone speaker is an electronic component of a mobile phone, a sound-generating unit, or a speaker. It is generally classified into dynamic, electromagnetic, inductive, and flat types. To improve the waterproof performance of current smartphones, a waterproof and sound-permeable membrane is usually applied to the surface of the speaker. This ensures that the sound from the phone is transmitted normally while also making the speaker waterproof.

[0004] After searching, the Chinese patent application number 201921276888.6 discloses a new waterproof sound-permeable membrane, including a sound-permeable membrane body, with upper double-sided tape and lower double-sided tape on both sides of the sound-permeable membrane body, a layer of buffer foam is provided on the upper double-sided tape, the upper double-sided tape is used to bond the buffer foam, and a layer of PET release film is provided on the bottom of the lower double-sided tape; an improvement of the above technical solution, the upper double-sided tape, the lower double-sided tape and the buffer foam are all provided with sound-permeable holes, and the sound-permeable holes are used for sound transmission of the sound-permeable membrane; the sound-permeable holes are located in the middle of the upper double-sided tape, the lower double-sided tape and the buffer foam.

[0005] The above patent has the following shortcomings: the device mainly uses buffering foam to increase the tension on the surface of the waterproof sound-permeable membrane and reduce the possibility of wrinkles on the surface of the waterproof sound-permeable membrane; however, when applied to the mobile phone speaker, the buffering foam itself is also a relatively soft material. If the buffering foam is bent during the process of pasting the waterproof sound-permeable membrane, the buffering foam itself can quickly return to a flat state, but the waterproof sound-permeable membrane will still have wrinkles, which is not conducive to the assembly of the waterproof sound-permeable membrane and the mobile phone speaker.
