Flexible ultra-thin loudspeaker
The invention belongs to the technical field of loudspeakers, and in particular
relates to a flexible ultra-thin loudspeaker.
The traditional speaker structure is a conical structure. The structure of the
conical speaker is divided into a cone with a vibrating plate and a cavity structure that
produces resonance. However, the traditional loudspeaker structure has problems such
as large weight and large volume, and it is more troublesome to transport and install,
and it is increasingly not suitable for the fashionable and brisk life requirements of
modern citizens. The above-mentioned problems need to be solved urgently.
In view of the deficiencies in the prior art, the invention provides a flexible
ultra-thin loudspeaker. The thin-film speaker has the advantages of large flexible area,
lightness and thinness, and can be cut arbitrarily according to actual needs.
In order to solve the above technical problems, the present invention is solved by
the following technical solutions: the flexible ultra-thin loudspeaker includes a
substrate, a conductive thin film layer is arranged on one side of the substrate, the
conductive thin film layer is a square double helix loop structure, and a strong
permanent magnet device is arranged on the other side of the substrate, the conductive
film layer is also provided with conductive terminals for connecting the signal
processor and the audio processor.
In order to obtain better technical effects, further technical improvements are: the
conductive thin film layer comprises a spiral loop circuit J and a spiral loop circuit
,the spiral loop circuit J and the spiral loop circuit @ are connected.
In order to obtain better technical effects, further technical improvements are: the
substrate is a flexible plate.
In order to obtain better technical effects, further technical improvements are: the
substrate is a high-molecular polymer insulating plate.
In order to obtain better technical effects, further technical improvements are: the
high molecular polymer insulating plate is made of PT or PET or PI.
In order to obtain better technical effects, further technical improvements are: the
conductive thin film layer is aluminum foil or a single gold copper film.
In order to obtain better technical effects, further technical improvements are: the
strong permanent magnet device is a neodymium iron boron magnet block.
The beneficial effect of the invention is that the thin-film speaker is prepared by
using three-dimensional printing technology, some key process parameters in the
synthesis process can be greatly improved in the full frequency range of the sound by
appropriately controlling, and the process has high repeatability; the thin-film speaker
has the advantages of flexible large area, lightness and thinness, and can be cut
according to actual needs (only need to reset the conductive segment), and meet the
needs of various situations. The process is simple, the controllability is strong, the
sound effect is good, simple and fashionable, convenient and practical, and can bring
great economic benefits.
Fig.1 is a schematic front view of the invention.
Fig. 2 is a schematic cross-sectional view of the section along A- A in Fig. 1.
The invention will be further described in detail below in conjunction with the
drawings and specific embodiments.
Example: Refer to FIG. 1 and FIG. 2 for a specific example of the film speaker
of the invention. The flexible thin-film speaker includes a substrate 1, and the
substrate 1 is a flexible high-molecular polymer insulating plate. The square spiral
conductive metal thin film layer 2 is provided on one surface of the substrate 1, and
the conductive film layer 2 has a square double spiral loop structure, the strong
permanent magnet device 3 is provided on the other side of the substrate 1, the
conductive metal thin film layer 2 is aluminum foil layer or single gold copper film, a
strong permanent magnet device 3 is provided on the other side of the substrate 1, and
a conductive terminal 4 for connecting a signal processor and an audio processor is
also provided on the conductive film layer 2. The conductive terminals 4 are one or
two. .
Further, the conductive thin film layer 2 comprises a spiral loop circuit D 21
and a spiral loop circuit @ 22, the spiral loop circuit ( 21 and the spiral loop
circuit @ 22 are connected.
Further, the substrate can be made of heat-resistant materials such as PT, PET, or
When the external signal processor and audio processor are connected through
conductive terminals and the film speaker starts to provide audio signals, the charge is
transferred to the square spiral conductive metal layer of the thin-film speaker, the
metal thin film layer can be charged, and the metal thin film layer in the middle can
vibrate, which then compresses the air to produce sound.
The thin-film speaker is prepared by using three-dimensional printing technology,
some key process parameters in the synthesis process can be greatly improved in the
full frequency range of the sound by appropriately controlling, and the process has
high repeatability; the thin-film speaker has the advantages of flexible large area,
lightness and thinness, and can be cut according to actual needs (only need to reset the
conductive segment), and meet the needs of various situations. The process is simple,
the controllability is strong, the sound effect is good, simple and fashionable,
convenient and practical, and can bring great economic benefits.
In the above technical solution, the thin-film speaker can be applied to mobile
phone covers, wallpapers, photo frames, coasters, murals or lighting cover products.
In the above technical solution, the thin-film speaker can be applied to slogans,
banners or other media display.
In the above technical solution, the thin-film speaker can be applied to earphones,
mobile phones, computers, electronic watches or electronic eye glasses.
The above-listed are only specific embodiments of the present invention.
Obviously, the present invention is not limited to the above example. All
modifications that can be directly derived or imagined by a person of ordinary skill in the art from the disclosure of the present invention shall fall within the protection scope of the present invention.
