Problems solved by technology

Figure 10 In the conventional earmuffs 60 shown, the volume of the front air chamber 64 is occupied by the depth dimension of the groove 622 and accordingly becomes smaller, resulting in reduced sound insulation.
On the other hand, in the headphone described in Patent Document 1, since the fixing member of the ear pad is used, although the shape of the conventional sound insulation board is avoided from occupying the volume of the front air chamber, the number of parts is increased, making the more complex structure

Embodiment 1

[0027] Below, the embodiments of the earmuffs involved in the present invention will be described with reference to the accompanying drawings. figure 1 It is a vertical cross-sectional view of an example of an earmuff according to the present invention. figure 1 In the illustrated earmuffs 10 , a sound insulating plate 12 is fixed to the opening of the ear cup 11 , and an earpad 13 is fixed to the sound insulating plate 12 . The space surrounded by the sound insulation board 12 and the ear pads 13 is the front air chamber 14 .

[0028] The sound baffle 12 is a member that closes the opening of the earcup 11 and has a substantially circular shape. A rib 121 having a predetermined height is integrally formed on its outer peripheral surface. The skin piece 131 , which is a locking part formed of a part of the skin material of the ear pad 13 , is tightened by the elastic force of the ring-shaped locking member 15 and locked on the outer periphery of the rib 121 .

Embodiment 2

[0039] Next, combine Figure 4 Another embodiment of the earmuff of the present invention will be described. Figure 4 The illustrated earmuffs 10 a are provided with support members 123 that extend the ends of the ribs 121 of the earpad 10 in the first embodiment described above toward the center of the sound insulating board 12 .

[0040] The supporting member 123 is fixed at a prescribed position, and supports the side of the ear pad 13 facing the sound insulation board 12, so that even if the user puts on the earmuff 10a and the ear pad 13 is pressed against the sound insulation board 12, The ear pad 13 does not collapse to the front air chamber 14 side either. Due to the support member 123, even if the ear pad 13 is pressed against the front air chamber 14 side, it does not collapse, so the volume of the front air chamber 14 can be ensured.

[0041] As described above, according to the earmuffs of the present invention, the volume of the front air chamber can be increas...

Embodiment 3

[0044] Next, combine Figure 5 Still another embodiment of the earmuffs according to the present invention will be described. Figure 5The illustrated earmuff 10b is provided with a support member 124 positioned on the front portion of the sound insulation panel 12 of the earmuff 10 in the first embodiment described above.

[0045] The supporting member 124 is fixed at a predetermined position and has a shape and size capable of supporting the surface of the earpad 13 facing the sound insulation panel 12, so that even if the user puts on the earmuffs 10b, the earpad 13 is subjected to a force directed toward the sound insulation panel 12. When squeezed, the ear pad 13 will not collapse to the front air chamber 14 side. The supporting member 124 does not need to be arranged on the entire circumference of the sound insulation board 12 , and its size (thickness, height, length) is based on the volume that does not press the front air chamber 14 .

[0046] As described above, ac...

Abstract

The present invention relates to an earmuff and a headphone, wherein the earmuff (10) includes a baffle board (12) fixed on a casing (11), and an ear pad (13) fixed because a part of a skin member of the ear pad (13) is fastened on the baffle board (12), the baffle board (12) and the ear pad (13) form a front air chamber (14), wherein the ear pad (13) is provided with an engagement member (131) being an outwardly extended part of the skin member of the ear pad (13), the baffle board (12) is provided with a rib member (121) fixedly provided with an engagement member (131) on the outer circumference, the engagement member (131) is fixed on the rib member (121) by a ring-shaped elastic member (15), and the ear pad (13) is fixed to the baffle board (12).

Description

technical field [0001] The present invention relates to an earmuff and a headphone, and more particularly, to an earmuff and a headphone whose sound insulation against external noise is improved by increasing the volume of a front air chamber. Background technique [0002] Figure 10 The sectional view of is an example of a conventional earmuff. Figure 10 In the earmuff 60 shown, the sound insulation board 62 is fixed to block the opening of the earcup 61, the ear pad 63 is fixed to the sound insulation board 62, and the space surrounded by the sound insulation board 62 and the ear pad 63 is the front air chamber 64. . [0003] The sound insulation board 62 has a shape in which two ring-shaped members with different outer diameters are axially separated, and a flange portion 621 is formed on the outer peripheral portion of the front ring-shaped member, which is a skin piece that is a part of the skin material of the ear pad 63 (Flap) 631 covers the flange portion 621 . ...
