Abstract
An transparent acoustic tuning film (acoustic damper) has a film sheet and the film sheet is thin and transparent. The film sheet can be various shapes as design requirements, and the film sheet has one or more than one fine aperture with a diameter smaller than 0.4 mm. Due to the dimension of the fine aperture, the fine aperture is used for tuning purpose and also is permeable and water-resistant. The film sheet further has an adhesive region provided on one side, and the adhesive region is capable of create tight seal. Furthermore, the adhesive region is applied with colorful water-resistant glue.
Description
- 1. Field of the Invention
- The present invention relates to an acoustic damper, and more particularly to a transparent permeable tuning film sheet with one or more than one fine aperture.
- 2. Description of Prior Art
- Currently various personal electronic devices have higher and higher standards.
- For example, for audio effect, some users like to add an external speaker for better sound quality. Conventional speakers include a tuning sheet (acoustic damper) for adjusting output audio frequencies. However, different material and installation of the tuning sheet can cause different sound quality. Common tuning materials are long-fiber paper, non-woven fabric and mesh. The long-fiber paper and the non-woven fabric both have irregular pores on their surfaces which cause inconsistent permeability. The mesh is woven by thin threads having different diameters and has instable tension strength and irregular apertures. All three materials have inconsistent air permeabilities.
- Therefore, it is desirable to provide a transparent acoustic damper to mitigate and/or obviate the aforementioned problems.
- In order to achieve the above-mentioned objective, a transparent acoustic damper having an adhesive region is disclosed (viewable) by the present invention.
- The film sheet has an irregular shape, one or more than one fine aperture, and an adhesive region. The fine aperture of the film sheet has a diameter smaller than 0.4 mm. The adhesive on the transparent film sheet is viewable for easy installation inspection. The film sheet is made of transparent polyimide material.

FIG. 1-FIG . 4. A transparent acoustic damper comprises afilm sheet 11 and thefilm sheet 11 is thin and transparent. Thefilm sheet 11 can be various shapes as design requirements, and thefilm sheet 11 has one or more than onefine aperture 110 with a diameter smaller than 0.4 mm. Due to the dimension of thefine aperture 110, thefine aperture 110 is used for tuning acoustic performance and also control the air permeability and water-resistant ability. Thefilm sheet 11 further has anadhesive region 111 provided on one side, and theadhesive region 111 is capable of create tight seal. Furthermore, theadhesive region 111 could be applied with colorful water-resistant glue. - Please refer to
FIG. 2-FIG . 6 together. The shape of thefilm sheet 11 is a half-moon shape, a horse-shoe shape or a circular shape. Thefilm sheet 11 can be cut into different shapes to match a speaker 10 (as shown inFIG. 5 andFIG. 6 ) when the film sheet is adhered onto thespeaker 10 with theadhesive region 111, and one or more than onefine aperture 110 are added in at a non-adhesive region. Since thefine aperture 110 is permeable and water-resistant and the glue applied on theadhesive region 111 is also water-resistant, thefilm sheet 11 provides water-resistant ability to thespeaker 10. Moreover, thefine apertures 110 are disposed corresponding to a plurality ofair ports 100 ofspeaker 10, and the number and size of thefine apertures 110 can control the output sound quality. - Conventional tuning sheet is not transparent; therefore when the tuning sheet is unstable placed , the output sound quality can be affected. Furthermore, if the convention adhesive glue is diffuses to cover the
air port 100 of thespeaker 10, it cannot be inspected, and the output sound quality can also be affected. - Since the
film sheet 11 of the embodiment of the present invention is transparent, it is possible to inspect whether the installation position of the tuning sheet is correct. - According to the embodiment of the invention, one
fine aperture 110 or more than onefine apertures 110 with a diameter smaller than 0.4 mm are provided at the non-adhesive region. - Conventional water-resistant sheets are usually Teflon film which has very poor permeability. However, the adjustable acoustic tuning film disclosed in the present invention is transparent, water-resistant and permeable.
- Furthermore, please refer to
FIG. 7 andFIG. 8 . The transparent acoustic tuning film of the preferred embodiment of the present invention is also suitable for being applied onto anearphone 2. The number of thefine apertures 110 can tune characteristic of the output sound. As shown inFIG. 7 , thefilm sheet 11 is respectively disposed in front of afront casing 21 and arear casing 22, anearphone speaker 20 is placed between thefilm sheet 11 and thefront casing 21, anelectric wire 23 is connected to theearphone speaker 20 through therear casing 22, and anear cushion 24 is placed in front of thefront casing 21. Therefore, the tune of the output sound of theearphone 2 can be adjusted by changing the position of thefilm sheet 11 and the number of thefine apertures 110. - Moreover, the transparent acoustic tuning film of the preferred embodiment of the present invention is also suitable for a speaker with an
enclosure 3. As shown inFIG. 8 , thefilm sheet 11 is disposed on afirst opening 30 and asecond opening 31. Via thespeaker 32, the tune of the output sound of the speaker with anenclosure 3 can be adjusted by changing the position of thefilm sheet 11 and the number of thefine apertures 110. - Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
