Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment 1
The sponge for earphone ear muff of the present embodiment, as shown in Figure 1 to Figure 3, comprise spongiosum 1, spongiosum 1 has through hole 9, and through hole 9 is that the sound of earphone provides sound channel.The shape of spongiosum 1 is not fixed, and determine according to the shape of concrete earphone ear muff, as circle, ellipse, irregular figure etc., the shape of through hole 9 is not also fixed, and its object is just for headphones sound provides sound channel.In the present embodiment, the cross section of through hole 9 is circular, and spongiosum 1 entirety in the form of a ring.
First end face of spongiosum 1 is provided with the first sound deadening sheet 2, second end face of the spongiosum 1 relative with the first end face is provided with the second sound deadening sheet 4, first sound deadening sheet 2, second sound deadening sheet 4 is respectively equipped with the perforation 6 communicated with through hole 9, and perforation 6 is also circular port, and diameter is less than the diameter of through hole 9.First sound deadening sheet 2 is connected to form connecting portion 3 along the periphery of perforation 6 and the second sound deadening sheet 4, spongiosum 1 is positioned at the space that connecting portion 3, first sound deadening sheet 2 and the second sound deadening sheet 4 are formed, namely sponge and through hole 9 keep apart together with connecting portion 3 by the first sound deadening sheet 2, second sound deadening sheet 4, avoid spongiosum 1 and absorb sound.
The thickness of first sound deadening sheet 2, second sound deadening sheet 4 of the present embodiment is respectively 0.01 ~ 0.2mm, such as 0.05mm, 0.1mm, 0.12mm, 0.15mm, 0.18mm.
In order to fix the first position of sound deadening sheet 2, second sound deadening sheet 4 on spongiosum 1, being provided with between the first sound deadening sheet 2 and the first end face of spongiosum 1 between first tack coat 7, second sound deadening sheet 4 and the second end face of spongiosum 1 and being provided with the second tack coat 8.First tack coat 7, second tack coat 8 can adopt the conventional adhesive for bond sponge and sound deadening sheet.
First sound deadening sheet 2, second sound deadening sheet 4 can adopt the film with sound insulation function, such as TPU membrane, PVC film, PU film, PPS film, TPU membrane, PVB film or PET film.
The formation of connecting portion 3 can in the following way: the first sound deadening sheet 2 is connected by hot-melt adhesive paste or sewing along the periphery of perforation 6 with the second sound deadening sheet 4.In order to simplify production technology and cost-saving, connecting portion 3 adopts the mode of hot-melt adhesive paste to be formed.
Adopt the earphone ear muff that the sponge of the present embodiment is made, comprise the body in housing shape, body is specially leather sheath, and the sponge of the present embodiment is then filled in this body.The earphone of employing the present embodiment sponge avoids sponge absorption sound and causes the situation of sound dispersion, so headphones sound has preferably stability.
The sponge of the present embodiment in the preparation, first paste full wafer sound deadening sheet respectively in the both ends of the surface of sponge, now sound deadening sheet not yet offers perforation 6, then hot pressing is carried out, after hot pressing, first sound deadening sheet 2 and the second sound deadening sheet 4 along through hole 9 inner circumferential hot-melt adhesive paste together with, the part linked together forms connecting portion 3, and connecting portion 3 inner circumferential forms perforation 6; The sponge of formation the present embodiment after hot pressing completes.When preparing earphone ear muff, only sponge need be filled in leather sheath.
