The wearing piece 30 comprises a shell 31 and a loudspeaker 32, the shell 31 comprises a concave section 312, the concave section 312 is formed with a concave 314 downward in a wearing state, and the concave section 312 is provided with a first sound outlet 301; the speaker 32 is disposed on the concave section 312, and a resonant cavity 303 is formed between the speaker 32 and the first side wall 317 of the housing 31, the first sound outlet 301 is communicated with the resonant cavity 303, and the first sound outlet 301 is used for producing sound; in the direction of the interval between the speaker 32 and the side wall of the housing 31, the thickness of the end of the resonant cavity 303 close to the first sound outlet 301 is greater than the thickness of the end of the resonant cavity 303 far from the first sound outlet 301, so that the cavity length of the resonant cavity 303 can be relatively shortened, and the resonant frequency of the Gao Xiezhen cavity 303 can be improved.

Specifically, the housing 31 has a top wall 315, a bottom wall 316, a first side wall 317, and a second side wall 318, the first side wall 317, the top wall 315, the second side wall 318, and the bottom wall 316 constituting the housing 31; wherein in the worn state the first side wall 317 is applied to the user's head and the second side wall 317 is directed towards the side facing away from the user's head.

In this embodiment, as shown in fig. 7, a resonant cavity 303 is formed between the speaker 32 and the first side wall 317 of the housing 31; in other embodiments, a resonant cavity 303 is formed between the speaker 32 and the second sidewall 318 of the housing 31; wherein the first sound outlet 301 is disposed on the bottom wall 316.

The top wall 315, the bottom wall 316, the first side wall 317 and the second side wall 318 also specifically constitute the first connecting section 311, the recessed section 312 and the second connecting section 313.

Optionally, the housing 31 may further include a plurality of concave sections 312, and at least one of the concave sections 312 may further be configured to be mounted on the auricle of the user, and the concave section 312 adjacent to the quick release assembly 20 may further be hinged to the quick release assembly 20; alternatively, the housing 31 includes a recessed section 312 and a second connecting section 313 as described above, and an end of the recessed section 312 remote from the second connecting section 313 is hinged to the quick release assembly 20.

Further, referring to fig. 5, taking a scenario in which the user wears the wearable device 100 as an example, in a wearing state, the concave section 312 is formed with a downward recess 314, that is, the concave section 312 extends toward the ear canal opening, so that the first sound outlet 301 disposed in the concave section 312 is close to the ear canal opening, which is beneficial to transmitting sound to the user.

In this embodiment, referring to fig. 3 and 6 in combination, the concave section 312 includes a first bending portion 3121 and a second bending portion 3122 connected in a bending manner, the speaker 32 is disposed at the second bending portion 3122, and the top walls 315 of the first bending portion 3121 and the second bending portion 3122 cooperate with each other to form a recess 314, in other words, the recess 314 is substantially V-shaped. The first connection section 311 is connected to an end of the first bending portion 3121 away from the second bending portion 3122, and the second connection section 313 is connected to an end of the second bending portion 3122 away from the first bending portion 3121.

The bending connection may be understood as that the extending directions of the first bending portion 3121 and the second bending portion 3122 are different, or that the first bending portion 3121 and the second bending portion 3122 are disposed at an angle.

It should be noted that, the top walls 315 of the first bending portion 3121 and the second bending portion 3122 referred to herein are portions of the top wall 315 of the wearing article 30 located on the first bending portion 3121 and the second bending portion 3122, respectively.

Alternatively, the concave section 312 may also have a U-shape or a W-shape, which is not specifically limited in this application.

As shown in fig. 4 and 5, the top wall 315 includes a first top surface 3151 at the first bending portion 3121 and a second top surface 3152 at the second bending portion 3122, the first top surface 3151 and the second top surface 3152 constituting the recess 314.

The bottom wall 316 includes a first bottom surface 3161, a second bottom surface 3162, and a third bottom surface 3163 that are sequentially bent and connected, the first bottom surface 3161 is located at the first bending portion 3121, the second bottom surface 3162 and the third bottom surface 3163 are located at the second bending portion 3122, and the first sound outlet hole 301 is disposed at the second bottom surface 3162.

By limiting the thickness of the end of the resonant cavity 303, which is close to the first sound outlet 301, to be greater than the thickness of the end of the resonant cavity 303, which is far away from the first sound outlet 301, in the interval direction between the speaker 32 and the first side wall 317 of the housing 31, the cavity length of the resonant cavity 303 can be equivalently shortened, so as to improve the resonant frequency of the resonant cavity 303, so that the frequency response curve generated by the speaker 32 is as flat as possible, and discomfort caused by resonance of the resonant cavity 303 when a user wears the device is avoided.

Specifically, if the concave section 312 is only provided with the first sound outlet 301 and is communicated with the resonant cavity 303, the resonant cavity 303 is in a form of having one end open and the other end closed, and when the cavity length of the resonant cavity 303 is equal to one fourth of the sound wave wavelength, the resonant cavity 303 generates a resonance peak, and the resonance peak is easy to cause discomfort of a user when the user wears the wearable device 100, so that the resonance frequency of the resonant cavity 303 needs to be moved to a high position; the higher the frequency, the shorter the wavelength, meaning that the cavity length should be as short as possible, so by defining the thickness of the end of the resonant cavity 303 close to the first sound outlet 301 in the direction of the interval between the speaker 32 and the first side wall 317 of the housing 31 to be greater than the thickness of the end of the resonant cavity 303 far from the first sound outlet 301, the cavity length of the resonant cavity 303 can be shortened, and the resonant frequency of the Gao Xiezhen cavity 303 can be increased, compared with the mode that the interval between the first side wall 317 and the speaker 32 is equal everywhere.

Referring to fig. 7, the thickness of the resonator 303 near the end of the first sound outlet 301 is greater than the thickness of the resonator 303 near the end of the first sound outlet 301, for example, the resonator 303 has two different thicknesses, a section near the first sound outlet 301 has a first thickness, a section far from the first sound outlet 301 has a second thickness, and the first thickness is greater than the second thickness; alternatively, the thickness of the resonant cavity 303 gradually decreases in a direction from an end near the first sound outlet 301 to an end far from the first sound outlet 301.

Alternatively, the thickness of the resonant cavity 303 gradually decreases from the end close to the first sound outlet 301 to the end far from the first sound outlet 301, and the direction of the resonant cavity 303 from the end close to the first sound outlet 301 to the end far from the first sound outlet 301 is defined as the length direction of the resonant cavity 303, and it is understood that the thickness of the resonant cavity 303 may decrease linearly or non-linearly along the length direction of the resonant cavity 303; for example, the thickness of the resonant cavity 303 is kept constant in a partial section near one end of the first sound outlet 301, and gradually decreases in a partial section far from the one end of the first sound outlet 301; alternatively, the thickness of the resonant cavity 303 is gradually reduced in a partial section near one end of the first sound outlet 301, and is maintained constant in a partial section far from the one end of the first sound outlet 301.

In some embodiments, the speaker 32 is directly matched with the first side wall 317 of the housing 31 to form the resonant cavity 303, and a distance between an end of the first side wall 317 of the housing 31 near the first sound outlet hole and a diaphragm plane of the speaker 32 is greater than a distance between an end of the first side wall 317 of the housing 31 far from the first sound outlet hole 301 and the diaphragm plane of the speaker 32.

The diaphragm plane of the speaker 32 is substantially a plane, and the first side wall 317 is a side wall having a different thickness, and an inner wall surface facing the speaker 32 is a slope, and a distance between the inner wall surface and the diaphragm plane forms a thickness of the resonant cavity 303.

In other embodiments, as shown in fig. 7, the wearing piece 30 further includes a shielding cover 33, where the shielding cover 33 is disposed between the speaker 32 and the first side wall 317 of the housing 31, and cooperates with the speaker 32 to form the resonant cavity 303; wherein, the distance between the end of the shielding cover 33 close to the first sound outlet 301 and the diaphragm plane of the speaker 32 is larger than the distance between the end of the shielding cover 33 far from the first sound outlet 301 and the diaphragm plane of the speaker 32.

Further, the shielding cover 33 includes a first cover 331 and a second cover 332 connected, and a distance between the first cover 331 and a diaphragm plane of the speaker 32 is greater than a distance between the second cover 332 and the diaphragm plane of the speaker 32, where the first cover 331 is disposed adjacent to the first sound outlet 301.

The first cover 331 and the second cover 332 may be equidistant from the diaphragm plane of the speaker 32, or the distance between the first cover 331 and the diaphragm plane of the speaker 32 may gradually decrease along the length direction of the resonant cavity 303, while the distance between the second cover 332 and the diaphragm plane of the speaker 32 may not change along the length direction of the resonant cavity 303.

By defining the spacing between the second enclosure 332 and the diaphragm plane of the speaker 32 to be smaller than the spacing between the first enclosure 331 and the diaphragm plane of the speaker 32, the cavity length of the resonant cavity 303 is further equivalently shortened by the second enclosure 332, thereby increasing the resonant frequency of the resonant cavity 303.

In this embodiment, the first cover 331 has a first plane 334 facing the speaker 32, the second cover 332 has a second plane 335 facing the speaker 32, and the first plane 334 and the second plane 335 are parallel to the diaphragm plane of the speaker 32, respectively, so as to simplify the structure of the shielding cover 33, and facilitate manufacturing.

Alternatively, the side of the first cover 331 facing the speaker 32 may be a slope, the slope gradually decreasing in distance from the plane of the diaphragm of the speaker 32 along the length of the resonant cavity 303, and the second cover 332 has a second plane 335 facing the speaker, and the second plane 335 is parallel to the plane of the diaphragm of the speaker 32.

The shielding cover 33 further includes a third cover 333, where the third cover 333 is connected between the first cover 331 and the second cover 332, the third cover 333 has a transition surface 336 facing the speaker 32, two opposite sides of the transition surface 336 are respectively connected to the first plane 334 and the second plane 335, and a distance between the transition surface 336 and a diaphragm plane of the speaker 32 is gradually reduced from the first plane 334 to the second plane 335, so as to smooth a side edge of the shielding cover 33 facing the diaphragm plane of the speaker 32, and avoid a loss of output sound energy caused by formation of a sharp corner structure.

Further, referring to fig. 5 and fig. 7 or fig. 8, the concave section 312 may further be provided with a second sound outlet 302, where the second sound outlet 302 is communicated with the resonant cavity 303, and the first sound outlet 301 and the second sound outlet 302 are located on two adjacent sides of the resonant cavity 303, where the second sound outlet 302 may be used for sounding and raising the resonant frequency of the resonant cavity 303.

The speaker 32 may be disposed at the first bending portion 3121 or the second bending portion 3122.

In the present embodiment, the speaker 32 is disposed in the first bending portion 3121, the first sound outlet 301 is disposed on the second bottom surface 3162, the second sound outlet 302 is disposed on the third bottom surface 3163, and the second sound outlet 302 can equivalently shorten the cavity length of the resonant cavity 303, so as to increase the resonant frequency of the resonant cavity 303.

Through setting up second sound hole 302 and first sound hole 301 that communicate resonant cavity 303, and first sound hole 301 and second sound hole 302 are located the adjacent both sides limit of resonant cavity 303 relatively, and wherein first sound hole 301 and second sound hole 302 all can be used to the sound production, and second sound hole 302 still can be used to shorten resonant cavity 303's cavity length to promote resonant frequency in resonant cavity 303, can make the frequency response curve that speaker 32 produced as far as possible even, avoid the uncomfortable sense when the user wears that resonant cavity 303 takes place the resonance and lead to.

Specifically, if the concave section 312 is only provided with the first sound outlet 301 and is communicated with the resonant cavity 303, the resonant cavity 303 is in a form of having one end open and the other end closed, and when the cavity length of the resonant cavity 303 is equal to one fourth of the sound wave wavelength, the resonant cavity 303 generates a resonance peak, and the resonance peak is easy to cause discomfort of a user when the user wears the wearable device 100, so that the resonance frequency of the resonant cavity 303 needs to be moved to a high position; the higher the frequency is, the shorter the wavelength is, which means that the cavity length should be as short as possible, so that by forming the second sound outlet 302 on one side of the cavity length, the cavity length of the resonant cavity 303 can be equivalently shortened, and the resonant frequency of the Gao Xiezhen cavity 303 can be improved. In other words, the side of the second sound outlet 302 is the side of the cavity 303 with the cavity length.

Specifically, the first sound outlet 301 is disposed on the second bottom surface 3162, and the second sound outlet 302 is disposed on the third bottom surface 3163.

Referring to fig. 8, fig. 8 is a schematic view of three cross-sectional structures of the resonant cavity in the wearing part shown in fig. 7.

In this embodiment, the rectangular cross section of the resonant cavity 303 is rectangular, the first side 3031 is a short side of the rectangle, the second side 3032 is a long side of the rectangle, and the second sound outlet 302 can equivalently shorten the cavity length of the resonant cavity 303 along the extending direction of the long side of the rectangle.

Further, the second sound outlet 302 extends from one end of the second side edge 3032 adjacent to the first side edge 3031 to the other end of the second side edge 3032 far away from the first side edge 3031, so that the cavity length of the resonant cavity 303 can be equivalently shortened, and the sound outlet effect of the first sound outlet 301 can be enhanced.

Optionally, the second sound outlet 302 can also be disposed in the middle of the second side edge 3032.
