Description
[technical field]
The present invention relates to electroacoustic field, a kind of particularly method that sound film is hot-forming.
[background technique]
Electro-acoustic element is as a component in electronic field, and with the development of electronics industry, electroacoustics system needs continuous
The requirements at the higher level for meeting consumer and properties of product being proposed, need more perfectly to show the essence of sound.
The quality of core sound-generating element of the sound film as loudspeaker, design directly affects the acoustical behavior of loudspeaker.
In general, the top dome of reinforcement can be designed on sound film, due to sound film and top dome be it is separated, need rear road to be glued at one by glue
It rises, gluing technique influences the promotion of production efficiency.
[summary of the invention]
To solve the above-mentioned problems, the present invention provides a kind of method that sound film is hot-forming, and the sound film includes central portion
With the ring portion of surrounding said central portion setting, which comprises
The first hot pressing film is provided, the first hot pressing film includes first part and the correspondence folding of the corresponding central portion
The second part of ring portion；
The second hot pressing film is provided, the second hot pressing film corresponds to the central portion；
First hot pressing film and the second hot pressing film described in hot binding, make the second hot pressing film and first hot pressing
First part's hot binding of film is formed as one the central portion, and the second part hot pressing of the first hot pressing film forms described
Ring portion, wherein the thickness of the central portion is greater than the thickness in the ring portion.
As an improvement the material of the first hot pressing film is identical as the material of the second hot pressing film.
As an improvement the first hot pressing film is polyether-ether-ketone or thermoplastic elastomer (TPE).
As an improvement the thickness of the first hot pressing film is equal to the thickness of the second hot pressing film.
As an improvement the thickness of the second hot pressing film is greater than the thickness of the first hot pressing film.
As an improvement the second hot pressing film is multi-layer film structure.
Advantageous effect of the invention is: the sound film that hot-press molding method through the invention is formed, the central portion of sound film is thicker,
Intensity improves, and does not need design top dome reinforcement, eliminates the process of rear road gluing top dome, reduce process, improve efficiency.
[Detailed description of the invention]
Fig. 1 is the schematic perspective view before sound film hot binding of the invention；
Fig. 2 is the schematic perspective view after sound film hot binding of the invention.
[specific embodiment]
Below by specific embodiment combination attached drawing, invention is further described in detail, so as to more preferable geographical
The advantages of solving the solution of the present invention and its various aspects.It below in an example, is level with the left and right directions of attached drawing paper
Direction, using the up and down direction of attached drawing paper as vertical direction.Additionally, it is provided the purpose of following specific embodiments is easy for this
The content of invention becomes apparent from thorough explanation, rather than limiting the invention.
The present invention provides a kind of methods that sound film is hot-forming, and the sound film 10 includes central portion 20 combined with Figure 1 and Figure 2,
With the ring portion 30 for surrounding the setting of central portion 20.
The method specifically includes:
First hot pressing film 11 is provided, the first hot pressing film 11 include first part 111 corresponding with central portion 20 and with folding
The corresponding second part 112 of ring portion 30；
Second hot pressing film 12, the corresponding central portion 20 of the second hot pressing film 12 are provided；
The first hot pressing of hot binding film 11 and the second hot pressing film 12, make the first of the second hot pressing film 12 and the first hot pressing film 11
111 hot binding of part is formed as one central portion 20, and 112 hot pressing of second part of the first hot pressing film 11 forms ring portion 30,
Wherein, the thickness of central portion 20 is greater than the thickness in ring portion 30.
Preferably, the material of the first hot pressing film 11 is identical as the material of the second hot pressing film 12, the material of the first hot pressing film 11
For PEEK (polyether-ether-ketone), TPE (thermoplastic elastomer (TPE)) or other high-molecular organic materials that may be used as sound membrane material.Make
For the situation that can choose, the thickness of the first hot pressing film 11 can be equal to the thickness or the second hot pressing film of the second hot pressing film 12
12 thickness is greater than the thickness of the first hot pressing film 11, in addition, the second hot pressing film 12 can be multi-layer film structure.
The sound film that hot-press molding method through the invention is formed, the central portion of sound film is thicker, and intensity improves, and does not need to set
Top dome reinforcement is counted, the process of rear road gluing top dome is eliminated, reduces process, improve efficiency.
It should be noted here that for those of ordinary skill in the art, before not departing from the invention design
It puts, various modifications and variations can be made, but these belong to the protection scope of invention.
