Description

Technical Field

[0001] The utility model relates to the technical field of acoustic equipment, in particular to a novel acoustic equipment. Background Art

[0002] The earplugs of existing acoustic devices are usually made of silicone, which has strong elongation and is very durable.

[0032] The novel acoustic device of the utility model may include earphones, hearing aids, auxiliary hearing earphones, auxiliary hearing devices and the like for processing and controlling sound. The earphones are taken as an embodiment of the utility model below.

[0033] See also Figure 1 One embodiment of the utility model discloses an earphone, including a host body and a mounting shell, wherein the host body includes a battery, a circuit board and a speaker, and is mounted inside the mounting shell. The host body is a prior art, which is not shown in the figure. It can be understood that in other embodiments, when it is a hearing aid, earphone, auxiliary hearing earphone or other acoustic device, the host body is selected as the host body of the corresponding hearing aid, earphone, auxiliary hearing earphone or other acoustic device.

[0034] The mounting housing at least includes an earplug 1, which can be connected to an earphone connection line, and can also be used with ear clips, earmuffs, ear hooks and other structures to work together on the ear to maintain stable clamping of the earplug 1. For example, in the present invention, the mounting housing also includes a hanging fixing portion 2, which is connected to the earplug 1. The hanging fixing portion 2 and the earplug 1 can be an integral structure or can be spliced.

[0035] See also Figure 2 and Figure 5 The earplug 1 includes an inner surface 11 of the earplug, an abutting portion 12 abutting against the ear on the side of the ear canal, a plurality of sound outlet holes 13, a sound outlet mouth 14 opposite to the ear canal, and a mounting surface 16. The abutting portion 12, the sound outlet holes 13, the sound outlet mouth 14, and the mounting surface 16 are all arranged on the inner surface 11 of the earplug, and the sound outlet hole 13 is arranged inside the sound outlet mouth 14. Preferably, the sound outlet mouth 14 is arranged away from the suspension fixing portion 2. The mounting surface 16 is arranged inside the earplug 1, and is the contact surface of the earplug 1 for mounting a speaker. Among them, the mounting surface 16 is a prior art, and its position is relatively fixed, and the utility model will not be repeated here.

[0036] The sound outlet 14 has an outer end surface facing the ear canal. The outer end surface protrudes from the abutting portion 12 and is inclined relative to the inner surface 11 of the earplug. The outer end surface is a smooth closed curve.

[0037] Among them, see Figure 3 The earplug 1 includes an inner side opposite to the ear and an outer side opposite to the ear. The inner side 11 of the earplug is the inner side of the earplug 1 opposite to the ear. Similarly, the side opposite to the ear is the back side of the earplug 1 (not shown in the figure). Here, the inner side 11 of the earplug is defined as the plane where the inner side and the outer side of the earplug 1 are adjacent and opposite to the ear.

[0038] In some embodiments, see also Figure 4 The sound outlet 14 includes an inner wall 141, a first side wall 142, an outer wall 143 and a second side wall 144 which are sequentially arranged as a whole. The inner wall 141 is closer to the center of the inner surface 11 of the earplug than the outer wall 143. The height of the first side wall 142 along the axial direction of the inner surface 11 of the earplug is smaller than the height of the second side wall 144 along the axial direction of the inner surface 11 of the earplug.

[0039] In some embodiments, the sound outlet 14 is provided with a highest point 145, a lowest point 146 and a geometric midpoint 147. The highest point 145 is provided on the second side wall 144, the lowest point 146 is provided on the first side wall 142, and the geometric midpoint 147 is the geometric midpoint of the outer end surface. The highest point 145 is on the side close to the ear canal, and the lowest point 146 is on the side close to the posterior groove of the auricle, which is ergonomic and the sound outlet is closest to the ear canal.

[0040] The height of the highest point 145 from the mounting surface 16 is 3.6 mm to 5.6 mm, the height of the lowest point 146 from the mounting surface 16 is 2.1 mm to 4.1 mm, and the height of the geometric midpoint 147 from the inner surface 11 of the earplug is 3.1 mm to 5.1 mm. When setting the heights of the highest point 145, the lowest point 146, and the geometric midpoint 147, the height of the highest point 145 from the mounting surface 16>the height of the geometric midpoint 147 from the mounting surface 16>the height of the lowest point 146 from the mounting surface 16.

[0041] When the sound outlet 14 is projected along the inner surface 11 of the earplug, the highest point 145, the lowest point 146 and the geometric midpoint 147 are connected to form an arc with a curvature of 0.17, a radius of 5.74 mm, and an arc length of 9.3 mm to 11.3 mm, that is, the maximum length of the sound outlet 14 is 9.3 mm to 11.3 mm. The shortest straight line connecting the inner wall 141 and the outer wall 143 through the geometric midpoint 147 is 2.5 mm to 4.5 mm, that is, the maximum width of the sound outlet 14 is 2.5 mm to 4.5 mm.

[0042] In some embodiments, a polar coordinate system is established with the center point of the mounting surface 16 as the pole O, which is not shown in the figure, wherein OX is the polar axis, and after wearing, the polar axis OX is centered at point O and the direction of OX is toward the horizontal direction of the line of sight, and the length unit is mm. Among them, the polar coordinates of the projection of the highest point 145 on the mounting surface 16 are (3.8~7.8, 323.1°~343.1°), and the polar coordinates of the projection of the lowest point 146 on the mounting surface 16 are (3.7~7.7, 209.3°~229.3°). The position of the highest point 145 or the lowest point 146 can be determined based on the polar coordinates of the projection of the highest point 145 or the lowest point 146 on the mounting surface 16 and the height of the highest point 145 or the lowest point 146 from the mounting surface 16.

[0043] In some embodiments, the polar coordinate system described above is used, and the polar coordinates of the projection of the geometric midpoint 147 on the mounting surface 16 are (3.5-7.5, 266.6°-286.6°). The position of the geometric midpoint 147 can be determined based on the polar coordinates of the projection of the geometric midpoint 147 on the mounting surface 16 and the height of the geometric midpoint 147 from the mounting surface 16. That is, the geometric midpoint 147 can be set at a height of 3.1 mm-5.1 mm from the mounting surface 16, and the length between the projection of the geometric midpoint 147 on the mounting surface 16 and the center point of the mounting surface 16, i.e., the origin O, is 3.5 mm-7.5 mm, and the angle between the geometric midpoint 147 and the polar axis is 266.6°-286.6°. For example, the height between the geometric midpoint 147 and the mounting surface 16 can be selected as 5.4 mm, 6.2 mm, 7.0 mm, etc., and the polar coordinates of the projection of the geometric midpoint 147 on the mounting surface 16 can be (3.5, 267°), (5.5, 267°), (3.5, 276°), (6.5, 286°), etc. The same is true for the highest point 145 and the lowest point 146.

[0044] In some embodiments, see Figure 6, the mounting shell also includes a filter 15 with a plurality of through holes, the filter 15 covers the sound hole 13 and is arranged on the sound outlet 14, and the shape of the filter 15 matches the shape of the sound hole 13. Alternatively, the filter 15 covers the sound hole 13 and the outer end surface, and the shape of the filter 15 matches the shape of the outer end surface. Preferably, the shape of the outer end surface can be circular, elliptical or mouth-like. Among them, the mouth-like shape refers to a shape similar to that of a human mouth when it is open. Similarly, the shape of the filter 15 can be the same as the shape of the sound outlet 14.
