[0037] Please refer to Figures 1 to 6 Now, the earmuff 100 and the head-mounted ANC noise reduction headset in the embodiment of the present invention are described.

[0038] Please refer to Figures 1 to 4The present application provides an earmuff 100 including a sound absorbing member 12 and a soft gel 13. The soft gel 13 is disposed on the outer surface of the sound absorbing member 12, and the Shore hardness of the soft gel 13 is in the range of 0 to 95A. Specifically, the sound absorbing member 12 is a sponge, preferably a memory foam, and the cross-section of the sound absorbing member 12 is elliptical, and the support member 11 is a hollow structure. In the prior art, most earmuffs 100 are only filled with sponges. Since there are a large number of pores inside the sponge, the noise reduction effect of such earmuffs 100 is not ideal. In the present application, by disposing a layer of soft gel 13 with a Shore hardness of 0 to 50A on the outer surface of the sponge, the noise reduction effect of the earmuff 100 can be effectively improved.

[0039] As an example, the Shore hardness of the soft rubber 13 can be 0A, 5A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 45A, 50A, 55A, 60A, 65A, 70A, 75A, 80A, 85A, 90A, 95A or a range between any two of the foregoing values. By controlling the Shore hardness of the soft rubber 13 within the above range, the comfort of the user can be improved.

[0040] In some embodiments, please refer to Figure 1 The earmuff 100 further includes a support member 11 and an outer skin component 200. The outer skin component 200 is connected to the support member 11. The outer skin component 200 and the support member 11 together wrap the sound absorbing member 12 and the soft glue 13. Specifically, the support member 11 is a glue member.

[0041] In some embodiments, please refer to Figures 1 to 4 The outer peripheral surface of the sound absorbing member 12 is provided with soft rubber 13 .

[0044] The above three distribution modes of the soft glue 13 can all improve the noise reduction effect of the earmuff 100. When the outer peripheral surface of the sound absorbing member 12 and the surface of the sound absorbing member 12 away from the supporting member 11 are both provided with the soft glue 13, the noise reduction effect of the earmuff 100 is better.

[0045] In some embodiments, please refer to Figures 1 to 4 , the soft glue 13 completely covers the outer peripheral surface of the sound absorbing member 12. Such an arrangement can further improve the noise reduction effect of the earmuff 100.

[0046] In some embodiments, please refer to Figures 1 to 4, the soft glue 13 completely covers the surface of the sound absorbing member 12 away from the supporting member 11. Such an arrangement can further improve the noise reduction effect of the earmuff 100.

[0047] In some embodiments, please refer to Figures 1 to 4 The inner circumferential surface of the sound absorbing member 12 is provided with a soft rubber 13, and the soft rubber 13 here plays a sealing role.

[0049] In some embodiments, the soft glue 13 is formed by an injection molding process, and the soft glue 13 is sleeved on the sound absorbing member 12 .

[0050] In some embodiments, the thickness of the soft glue 13 disposed on the outer peripheral surface of the sound absorbing member 12 is 0.5 to 2 mm. As an example, the thickness of the soft glue 13 disposed on the outer peripheral surface of the sound absorbing member 12 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm or a range between any two of the foregoing values, preferably 1 mm.

[0051] In some embodiments, the thickness of the soft glue 13 disposed on the surface of the sound absorbing member 12 away from the support member 11 is 0.3-1 mm. As an example, the thickness of the soft glue 13 disposed on the surface of the sound absorbing member 12 away from the support member 11 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm or a range between any two of the foregoing values, preferably 0.5 mm.

[0052] In some embodiments, the thickness of the soft glue 13 disposed on the inner circumference of the sound absorbing member 12 is 0.3-1 mm. As an example, the thickness of the soft glue 13 disposed on the inner circumference of the sound absorbing member 12 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm or a range between any two of the foregoing values, preferably 0.5 mm.

[0054] By limiting the thickness of the soft glue 13 at various locations of the sound absorbing member 12 to the above range, the noise reduction effect of the earmuff 100 can be ensured while reducing the cost.

[0055] In some embodiments, the material of the soft rubber is one of silicone, gel, TPU, TPE, TPR, PVC and rubber.

[0056] Please refer to Figure 5 and Figure 6 In the frequency response test diagram, the horizontal direction is frequency, the unit is Hz, and the vertical direction is sound intensity, the unit is dB.
