2 and 3, the vibration reduction device 300 according to an embodiment of the present invention includes a case 100 and a mounting part 200.

First, the case 100 is provided to accommodate the speaker 20 and to be mounted to the mask front 30, and includes a housing 110 and a wing 120.

The accommodating part 110 is a part in which the speaker 20 is accommodated and seated, and a hole (not shown) having a shape corresponding to the shape of the speaker 20 is formed therein so that the speaker 20 can be seated. . In addition, a coupling hole 111 may be formed in a predetermined portion of the accommodating part 110, for example, an edge portion of the accommodating part 110. This coupling hole 111 will be described later. .

The wing part 120 is formed in the both ends of the accommodating part 110. FIG. The wing 120 may be formed to extend from both ends of the receiving portion (110). Such a wing portion 120 is fitted to the mounting portion 200, the case 100 and the speaker 20 accommodated in the receiving portion 110 of the case 100 is to be mounted on the back of the mask front (30). To help.

In addition, the wing 120 may be formed of a metal material. Preferably, the wing part 120 is formed of a metal material integrally with the receiving part 110. In addition, the wing portion 120, it is preferable that both ends are formed round, in particular, the wing portion 120 is formed of a metal material, both ends are formed to be bent so as to be folded, respectively, so that both ends are easily It can be formed round. Thus, by forming the wing 120 rounded, when the mounting portion 200 to be described later is formed of a plastic material, scratches or damage to the mounting portion 200 by the end of the wing portion 120 formed of a metal material does not occur This is to avoid.

The mounting part 200 may be formed on the rear surface of the mask front 30, more specifically, on the outside of the rib 31 of the mask front 30, and may be integrally formed with the mask front 30. Here, since the rib 31 is a general matter to those skilled in the art, detailed description thereof will be omitted here.

The mounting unit 200 as described above is fitted to the case 100, the speaker 20 to the case 100 and the speaker 20 accommodated in the housing 110 of the case 100 and the mask front ( 30, and absorbs the vibration of the speaker 20 mounted on the back of the mask front (30). The mounting part 200 may be formed on the mask front 30 so that one pair, that is, a pair, is disposed with respect to both ends of the case 100.

4 is an enlarged perspective view illustrating a portion of the vibration reduction device illustrated in FIG. 2, and FIG. 5 is a side view illustrating the tension member illustrated in FIG. 2.

Hereinafter, the mounting unit according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

First, referring to FIG. 4, the mounting part 200 includes a tension member 210 and a hook member 220.

The tension member 210 is formed on the rear surface of the mask front 30 so as to be disposed between the wing 120 and the rear surface of the mask front 30, respectively. The tension member 210, one side is connected to the case 100 through the fitting coupling with the wing 120, in this state connected to the case 100, from the wing 120 to the mask front 30 Absorb the vibration of the speaker 20 is transmitted.

To this end, the tension member 210 is formed to have elasticity in the vertical direction. In order to have elasticity in the vertical direction, the tension member 210 may be formed in an annular shape in which a hollow is formed therein. Accordingly, the tension member 210, when the vibration generated from the speaker 20 is transmitted through both ends of the wing portion 120 of the case 100, the vibration of the speaker 20 effectively while vibrating itself up and down direction Absorbed.

In addition, as shown in FIG. 5, the tension member 210 may have a recess 211 having a thickness thinner than the peripheral surface. The concave portion 211 may be formed by varying the thickness of a predetermined portion of the tension member 210, specifically, a center portion in the vertical direction of the tension member 210 to have a thickness smaller than the peripheral surface. By the concave portion 211, the tension member 210, the tension generating performance can be further improved, and thus the tension member 210 is transmitted to the mask front 30 through one side thereof. The vibration caused by the high output of the speaker 20 can be more effectively absorbed.

In addition, the tension member 210 may be formed to be concave at the other side coupled to the mask front 30. This is to allow the tension member 210 to be freely deformed in the left and right directions through the concave portion formed at the other side, so that the fitting of the case 100 and the mounting portion 200 can be made more easily. to be.
