For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0033] The acoustic device that is easy to clamp of the present invention may include earphones, hearing aids, auxiliary hearing earphones, auxiliary hearing devices, etc. for processing and controlling sound. The acoustic device that is easy to clamp is taken as an embodiment of the present invention below.
[0034] See also Figure 1 , is a schematic diagram of the structure of the current human right ear, wherein the tragus, the posterior groove of the auricle and the helix crus are arranged clockwise at the periphery of the right ear canal, and this part of the structure is closely related to the conveniently clamped acoustic device of the present utility model. The conveniently clamped acoustic device for wearing the right ear will be used as an example for explanation below, and it can be understood that the conveniently clamped acoustic device for wearing the left ear is similar.
[0035] See also Figure 2 and Figure 3 One embodiment of the utility model discloses an acoustic device that is easy to clamp, 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. Among them, 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, an auxiliary hearing earphone or other acoustic device, the host body is selected as the host body of the corresponding hearing aid, auxiliary hearing earphone or other acoustic device.
[0036] The mounting shell includes an earplug 1, a curved connecting section 2, and a back-of-ear clamping portion 3, which are separate independent parts connected in sequence to form a whole or themselves form a whole. The curved connecting section 2 extends beyond the surface on the same side of the back-of-ear clamping portion 3 and the earplug 1 at a contact point 22 where it contacts the skull at the ear tip (this surface can be regarded as a reference surface, and in other embodiments, this surface can also be regarded as a spatial plane). There are various ways in which the earplug 1, the curved connecting section 2, and the back-of-ear clamping portion 3 form a whole. For example, the earplug 1, the curved connecting section 2, and the back-of-ear clamping portion 3 are an integrally formed structure, or the earplug 1, the curved connecting section 2, and the back-of-ear clamping portion are spliced together to form a whole, or the earplug 1 and the curved connecting section 2, and the curved connecting section 2 and the back-of-ear clamping portion 3 are connected by other connecting structures to form the three into a whole. Reference Figure 3 In the direction, when the acoustic device that is easy to clamp is placed horizontally, the abutment point 22 is upward beyond the plane where the ear clamping part 3 and the earplug 1 are located. Preferably, the battery and the circuit board are installed in the ear clamping part 3, and the speaker is installed in the earplug 1. The speaker is connected to the circuit board through a conductor such as a wire. Titanium wire can be provided in the curved connecting section 2. Here, it is the existing technology of titanium wire, and is not limited to the use of other materials such as steel wire, iron wire, plastic, etc. The diameter of the titanium wire is 0.5-0.9mm.
[0037] See also Figure 4 , the clamping distance between the earplug 1 and the back-of-ear clamping part 3 for clamping the ear is 0.8mm-5.0mm. Among them, the curved connecting section 2 is an arc-shaped elastic structure, so that the earplug 1 and the back-of-ear clamping part 3 are close to each other but leave a clamping distance for clamping the ear. The clamping distance uses the closest point of the earplug 1 and the back-of-ear clamping part 3 as the measurement point. For example, in this embodiment, point A is the measurement point of the earplug 1, point B is the measurement point of the back-of-ear clamping part 3, and the straight-line distance between point A and point B is the clamping distance. The minimum clamping distance in the natural state where the ear hook does not deform is 0.8-1.5mm, and the maximum clamping distance is 5.0mm. Since the curved connecting section 2 is an elastic structure, the earplug 1 and the back-of-ear clamping part 3 can be close to each other within the elastic range, and the clamping distance can be consistent with the thickness of the wearer's ear when worn to ensure effective clamping. The specific clamping distance is determined according to the thickness of the wearer's ears, for example, 2.0 mm, 3.2 mm, 3.8 mm, etc. Different clamping distances are adapted to different wearers' ear thicknesses.

Similarly, the side opposite to the ear is the back side of the earplug (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.

The sound outlet 12 protrudes from the curved surfaces where the tragus contact portion 13, the auricle posterior groove contact portion 15 and the helix crus contact portion 14 are located. It can be understood that in another embodiment, the tragus contact portion 13, the helix crus contact portion 14 and the auricle posterior groove contact portion 15 are respectively curved surfaces, and the sound outlet 12 can protrude from the highest point of the curved surfaces where the tragus contact portion 13, the auricle posterior groove contact portion 15 and the helix crus contact portion 14 are located, and extend into the ear canal.
[0043] In some embodiments, the back-of-ear clamping portion 3 includes a pressing surface 31 which is in the same direction as the inner surface 11 of the earplug and is used to press against the head behind the ear. The pressing surface 31 protrudes from the surface where the inner surface 11 of the earplug is located. Preferably, the pressing surface 31 is a plane or a curved surface, or the shape of the pressing surface 31 matches the shape of the head.
[0044] See also Figure 6 , take the center of the central portion 16 as the origin point O, and establish a coordinate system through point O with a plane parallel to the horizontal plane where the inner surface 11 of the earplug is located, and the center of the pressing surface 31 is point D; the angle range of the line-plane angle between the line segment DO and the plane parallel to the inner surface 11 of the earplug passing through point O is 5° to 15°, that is, with the Z axis as the positive direction, when the earplug 1 is stationary, the angle formed by the back-of-ear clamping portion 3 relative to the initial position of the earplug 1 is at least 5° and at most 15°.
[0045] In some embodiments, with the pressing surface 31 as the reference surface, the inner surface 11 of the earplug can be offset along the axial direction of the pressing surface 31.

[0046] In some embodiments, see Figure 2 The curved connecting section 2 includes a first connecting section 21, a second connecting section 23 whose front projection is consistent with the arc line of the ear root, and a contact point 22 that contacts the head at the ear tip.

[0048] The utility model uses a three-point contact method (the tragus contact portion 13 that contacts the tragus, the abutment point 22 that abuts against the head at the ear tip, and the pressing surface 31 that presses against the head at the back of the ear) to fix the acoustic device that is easy to clamp on the ear, and the back-of-ear clamping portion 3 (pressing surface 31) can be adjusted relative to the earplug 1 (i.e., the tragus contact portion 13) to adapt to the ear thickness, head shape, etc. of different wearers.
