Specific embodiment
Below in conjunction with attached drawing, the diaphragm of loudspeaker and its manufacturing method of the embodiment of the present invention is further illustrated.
Fig. 1 to Fig. 3 is please referred to, as shown, the present invention provides a kind of diaphragm of loudspeaker, including vibrating diaphragm ontology 1 and bamboo charcoal
Sheet body 2.Wherein, the vibrating diaphragm ontology 1 has central part 11 and outstanding edge 12, and the outstanding edge 12 is connected to the central part 11
Periphery.The immersion of bamboo charcoal sheet body 2 has synthetic resin 21, and the bamboo charcoal sheet body 2 is set on the central part 11.
As described above, after natural bamboo progress charing process is mainly become bamboo charcoal by the diaphragm of loudspeaker of the invention, it will
The bamboo charcoal immerses in synthetic resin, is finally sliced again and completes the bamboo charcoal sheet body 2.The bamboo charcoal sheet body 2 that slice is completed is sheet,
It can again with macromolecule vibrating diaphragm ontology 1 (such as PEEK material) combine (such as the bottom surface of bamboo charcoal sheet body can attach glue-line with height
The fitting of molecule vibrating diaphragm ontology), to complete the diaphragm of loudspeaker of the invention.Bamboo charcoal is after carbonizing except with long-term preservation, not variable
Shape and avoid it is mouldy with outside the advantages of damaging by worms, it is often more important that, the density of bamboo charcoal is relatively original lower after charing, therefore has quality
Lighter advantage is conducive to the performance of Hi-Mid.In addition, though the material of the bamboo charcoal carbonized can become brittle, but suitably
It is immersed in synthetic resin the rigidity and flexibility that can then increase bamboo charcoal, keeps its non-breakable.Therefore, loudspeaker of the invention vibration
Film has the advantages that quality is lighter but rigidity is more preferable, at the same retain again the toughness of bamboo wood itself with it is internally-damped, make it in middle height
In the sound quality performance of frequency more preferably compared with material used in aforementioned conventional, distortion is also lower, and overall loudness is also more loud.
Fig. 1 and Fig. 3 is please referred to, as shown, the diaphragm of loudspeaker more may include glue-line 6, is attached at the bamboo charcoal
Between sheet body 2 and the central part 11, the glue-line 6 can be acrylic adhesive (acryl glue).The glue-line 6 can allow have from
Type film (not shown), the glue-line 6 can first be attached at the bottom of the bamboo charcoal sheet body 2 with the release film, later described in removal
Rapidly the bamboo charcoal sheet body 2 can be attached on the central part 11 after release film.
Fig. 1 to Fig. 3 is please referred to, as shown, the bamboo charcoal sheet body 2 can be formed by 5 years raw Meng's ancestor's bamboo charcoals.
Referring to FIG. 3, as shown, the synthetic resin 21 can be epoxy resin.The synthetic resin 21 immerses described
The immersion rate of bamboo charcoal sheet body 2 can be 15%~30%.In addition, the synthetic resin 21 immerses the immersion rate of the bamboo charcoal sheet body 2
It preferably can be 25%~30%.The immersion rate refers to the weight for the synthetic resin 21 that every 100 g of bamboo charcoal sheet body 2 is dipped into
Amount.
Please refer to figs. 1 to 4, as shown, the present invention separately provides a kind of manufacturing method of diaphragm of loudspeaker, comprising:
Bamboo charcoal is immersed into synthetic resin 21；
The bamboo charcoal for immersing synthetic resin 21 is cut into bamboo charcoal sheet body 2；And
Bamboo charcoal sheet body 2 is set to the central part 11 of vibrating diaphragm ontology 1, the periphery of central part 11 is connected with an outstanding edge 12.
In one embodiment of the present of invention, the bamboo charcoal can be formed by 5 years raw Meng's ancestor's bamboo charcoals.The Meng ancestor bamboo
Diameter can be at 16 centimeters or more, and Meng ancestor bamboo can be with slicer slicing at carbonizing again after required thickness.
In one embodiment of the present of invention, the bamboo charcoal can pass through 800 DEG C of heating, 96 hours charcoals by 5 years raw Meng Zongzhu
Change.Meng Zongzhu after slicing can use refractory ceramics board clamping, be sent into retort carbonized again later.Bamboo after charing
The moisture content of charcoal can be 10%~30%.In addition, the moisture content of the bamboo charcoal after charing preferably can be 20%~30%.It is described aqueous
Rate refers to the weight of the water contained by every g of bamboo charcoal.
In one embodiment of the present of invention, the synthetic resin 21 can be epoxy resin, and the bamboo charcoal after charing can be put into
The immersion processing of synthetic resin 21 is carried out in vacuum tank.The immersion rate that the synthetic resin 21 immerses the bamboo charcoal sheet body 2 can be
15%~30%.In addition, the immersion rate that the synthetic resin 21 immerses the bamboo charcoal sheet body 2 can be preferably 25%~30%.Institute
State the weight for the synthetic resin 21 that immersion rate refers to that every 100 g of bamboo charcoal sheet body 2 is dipped into.
In one embodiment of the present of invention, the bamboo charcoal sheet body 2 can be attached first be collocated with the glue-line 6 of release film after, cut out
Cut the bamboo charcoal sheet body 2, the release film and the glue-line 6 so that its form and dimension for corresponding to the central part 11, then
The bamboo charcoal sheet body 2 and the glue-line 6 are attached at the central part 11 again after the release film can be removed, the glue-line 6 can
For acrylic adhesive (acryl glue).The bamboo charcoal sheet body 2 can be rapidly attached at the central part 11 by the present invention as a result,
On.
In conclusion a kind of diaphragm of loudspeaker and its manufacturing method provided by the embodiment of the present invention, can make the matter of vibrating diaphragm
Measure it is lighter, while can make vibrating diaphragm have good rigidity with it is preferable internally-damped, with slow down the distortion of high frequency and absorb it is extra
Vibrational energy, promoted loudspeaker high frequency sound quality and volume show.
The above description is only an embodiment of the present invention, not to limit to the scope of the patents of the invention.
