Description
Technical Field
The utility model belongs to the technical field of the electro-acoustic conversion technique and specifically relates to a slim PEEK sound membrane is used to high-power loudspeaker of superlow sound.
Background
In recent years, with the further popularization of notebook computers, the requirements of customers on sound quality are further improved, and the users only need to have certain appreciation cognitive abilities on high and low tones from the prior art. This places a higher demand on the notebook computer speaker design, and the separate design of the bass and bass chambers is not without problems, but requires the matching of a specific woofer unit and tweeter unit. The low frequency part of the woofer unit is mainly determined by the vibration system of the voice coil voice diaphragm, the weight of the voice coil has an upper limit due to the limitation of size and resistance, at the moment, articles need to be made on the quality of the voice diaphragm, and the quality of the voice diaphragm is mainly determined by the middle paste of the dome.
The folding ring of the existing sound membrane is a PEEK folding ring and a PMI flat dome, the thickness of the folding ring is 0.4-0.7 mm, the folding ring can also be a PEEK folding ring and a wood flat dome, the thickness of the folding ring is 0.4-0.9 mm, but the rigidity of the domes made of the two materials is poor, the thickness is thick, the low-frequency effect is poor, and therefore one dome which has certain quality and good rigidity and is also thin at the same time needs to be selected to match the sound membrane for the woofer.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: a thin PEEK sound film for a subwoofer and a high-power loudspeaker is provided.
The utility model provides a technical scheme that its technical problem adopted is: a thin PEEK sound film for an ultra-low sound high-power loudspeaker comprises a folding ring and a ball top, wherein the ball top is arranged in the middle of the folding ring and is a medical stainless steel flat ball top or a pure aluminum flat ball top.
Furthermore, a cavity is arranged in the middle of the folding ring, a folding part is arranged at the inner ring of the folding ring, and the top of the ball is glued on the folding part through glue.
Furthermore, a flat plate is arranged in the middle of the folding ring, the folding ring and the flat plate are of an integrally formed structure, and the flat plate is glued with a ball top through glue.
Further, the sound film is round or square.
Further, the thickness of the sound film is 0.2 mm.
The utility model has the advantages that: the utility model discloses an its rigidity of pure aluminium dull and stereotyped dome behind medical stainless steel is bigger, and thickness is only 0.2mm, and highly thinner, the sound chamber of packing into is more advantageous, uses the back moreover, and the low frequency is higher than conventional loudspeaker by 5 ~ 6db, and the bass effect is stronger, and rated power can be promoted to 3W by 2W simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;
fig. 2 is an exploded view of the present invention;
fig. 3 is a frequency response curve diagram of the present invention.
In the figure: 1. a folded ring, 2, a dome, 4, a flat plate, a frequency response curve of a conventional sound film; b. frequency response curve of low frequency sound film.
Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Example 1:
the thin PEEK sound film for the ultra-low sound high-power loudspeaker shown in the figures 1-3 is suitable for a circular sound film or a square sound film and comprises a folded ring 1 and a ball top 2, wherein the ball top 2 is arranged in the middle of the folded ring 1, the folded ring 1 is a PEEK folded ring, the ball top 2 is a medical stainless steel flat plate ball top, the thickness of the sound film is 0.2mm, and the volume of the sound film suitable for the loudspeaker is 13 multiplied by 06 mm-50 multiplied by 22 mm.
The middle position of the folding ring 1 is provided with a flat plate 4, the folding ring 1 and the flat plate 4 are of an integrated structure, and the flat plate 4 is glued with a ball top 2 through glue.
During specific assembly, as a generating unit of a loudspeaker, the sound film has to have thin property, the dome 2 is a medical stainless steel flat dome, the corrugated rim 1 and the flat plate 4 are respectively molded at one time through a casting mold, glue is coated on the surface of the flat plate 4, and the dome 2 is glued on the flat plate 4 to form the sound film.
The curve a shown in fig. 3 is a frequency response curve of a conventional sound film, the curve b is a frequency response curve of the low-frequency sound film of the present application, and a comparison of the curve a and the curve b shows that the speaker using the sound film of the present application can reduce the low frequency band such as the low frequency band of 20Hz to 640Hz, the frequency response curve of the low frequency band of the speaker is about 5-6dB higher than that of the conventional sound film, and the bass effect is stronger.
Example 2:
the difference from example 1 is that: the ball top 2 is a pure aluminum flat plate ball top.
Example 3:
the difference from example 1 is that: the middle position of the folding ring 1 is provided with a cavity, the inner ring of the folding ring 1 is provided with a folding part, and the ball top 4 is glued on the folding part through glue.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
