[0021] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] See Figure 1 and Figure 2 , Figure 1 and Figure 2 These are schematic diagrams of the structure of the earphones provided in the embodiments of the present application. Figure 1 and Figure 2 As shown, the earphone comprises: a housing 10 and a sound-generating component (not shown), wherein an acoustic cavity 11 is provided in the housing 10. Figure 2 The acoustic cavity 11 is a spiral cavity, the sound-emitting component is arranged at one end of the shell 10, and the first sound outlet of the sound-emitting component is connected to the acoustic cavity 11.

[0024] The working principle of the embodiment of the present application can be described as follows:

[0025] Since an acoustic cavity 11 is provided in the shell 10, and the acoustic cavity 11 is a spiral cavity, when the sound emitted by the sound-emitting component propagates in the spiral cavity, compared with acoustic cavities 11 of other shapes, in this embodiment, when the sound propagates in the spiral cavity, the airflow can be regulated, resulting in better sound field width and low-frequency response, making the sound more layered and spatial, thereby enhancing the playback effect of the headphones.

[0026] It should be noted that, since the acoustic cavity 11 is a spiral cavity, Figure 1 and Figure 2 , it can be understood that the shell 10 is also a spiral shell, and the unique spiral appearance design of the shell 10 makes the earphones more visually attractive and recognizable, meets consumers' needs for fashion and personalization, and enhances user experience.

[0027] The earphones in the embodiment of the present application can be wireless earphones or wired earphones. When the earphones are wireless earphones, see Figure 3 , the wireless earphones can be placed in the dedicated earphone compartment 20.

[0028] The sound-producing component is a component for producing sound, and the specific type is not limited here. Optionally, the sound-producing component may be a speaker.

[0029] The specific arrangement of the sound-emitting component at one end of the shell 10 is not limited here. Optionally, the sound-emitting component can be snapped onto one end of the shell 10, or the sound-emitting component can be bonded to one end of the shell 10 through a glue layer.

[0030] It should be noted that the specific shape of the spiral cavity is not limited here. Optionally, the spiral cavity can be an S-shaped spiral cavity, or can be other spiral cavities.

[0031] For example: As an optional implementation, see Figure 1 , the acoustic cavity 11 is a nautilus-shaped cavity, that is, other spiral cavities can be nautilus-shaped cavities.

[0032] The acoustic cavity 11 is nautilus-shaped, and the spiral angle and shape of the nautilus-shaped cavity are carefully considered by acoustics, making it unique and one-of-a-kind. The technical principle of the nautilus-shaped cavity is to simulate the realistic hearing sensation produced by the natural rotation and flow of air, thereby providing a natural listening experience similar to that of open-ear recording, further enhancing the headphone playback effect and user experience.

[0033] In the embodiment of the present application, the acoustic cavity 11 is a nautilus-shaped cavity. In this way, when the sound propagates in the nautilus-shaped cavity, multiple reflections will occur, thereby optimizing the acoustic effect of the sound; at the same time, the nautilus-shaped cavity regulates the airflow to make the low-frequency sound dive deeper, obtaining a fuller and more three-dimensional sound effect, and further enhancing the playback effect of the headphones.

[0034] In addition, the acoustic cavity 11 is a nautilus-shaped cavity, so that the acoustic cavity 11 can conform to the structure of the human ear canal. When the earphones are worn on the human ears, the earphones fit the human ears and are more comfortable to wear, further enhancing the user experience.

[0035] As an optional implementation, see Figure 4 A second sound outlet 103 is provided on the other end of the shell 10 , and the second sound outlet 103 is connected to the sound leakage hole 111 of the acoustic cavity 11 .

[0036] The shape of the second sound outlet hole 103 may match the shape of the sound leakage hole 111 , and both the sound leakage hole 111 and the second sound outlet hole 103 may be used for sound emission.

[0037] In the embodiment of the present application, a second sound outlet 103 is provided on the other end of the shell 10, and the second sound outlet 103 is connected to the sound leakage hole 111 of the acoustic cavity 11, so that the noise reduction effect of the earphone can be better.

[0038] It should be noted that when the earphones in the embodiment of the present application are wireless earphones, and the number of wireless earphones is usually two, the two wireless earphones can be a wireless earphone for the left ear and a wireless earphone for the right ear respectively. In order to increase the usage scenarios of the wireless earphones and prevent the wireless earphones from being lost, see Figure 4 The two wireless earphones can also be connected via a connecting line 104, that is, the connecting line 104 can be detachably connected to the two earphones respectively.

[0039] As an optional embodiment, the sound leakage hole 111 is located at the center of the sound output surface of the acoustic cavity 11 , and the orthographic projection of the second sound output hole 103 on the sound output surface at least partially overlaps with the sound leakage hole 111 .

[0040] The sound outlet surface of the acoustic cavity 11 may be understood as a connection surface with the surface of the housing 10 on which the second sound outlet hole 103 is provided.

[0041] The orthographic projection of the second sound outlet 103 on the sound outlet surface at least partially overlaps with the sound leakage hole 111 , which can be understood as the second sound outlet 103 and the sound leakage hole 111 being at least partially arranged opposite to each other.

[0042] In the embodiment of the present application, the sound leakage hole 111 is located at the center of the sound outlet surface of the acoustic cavity 11, and the orthographic projection of the second sound outlet hole 103 on the sound outlet surface at least partially overlaps with the sound leakage hole 111, which can further improve the efficiency and accuracy of noise reduction.

[0043] As an optional implementation, the shape of the sound outlet surface of the acoustic cavity 11 matches the sound inlet of the human ear.

[0044] The sound inlet of the human ear may be located in the cavum concha of the human ear, that is, the sound inlet may be located at a certain position in the cavum concha.

[0045] In the embodiment of the present application, the shape of the sound outlet surface of the acoustic cavity 11 matches the sound inlet of the human ear. In this way, the sound outlet surface of the acoustic cavity 11 can perfectly fit the natural curve of the concha cavity of the human ear, thereby improving the wearing comfort and reducing the discomfort caused by long-term wearing.

[0046] As an optional implementation, see Figure 1 and Figure 2The shell 10 includes a first shell part 101 and a second shell part 102 connected to each other, the acoustic cavity 11 is arranged in the first shell part 101, and a connecting cavity is provided in the second shell part 102. The sound-emitting component is arranged on an end of the second shell part 102 away from the first shell part 101, and the first sound outlet is connected to the acoustic cavity 11 through the connecting cavity.

[0047] The specific shape of the connecting cavity is not limited here. Optionally, the connecting cavity can be a spiral cavity, and the shape of the connecting cavity can match the shape of the acoustic cavity 11.

[0048] In the embodiment of the present application, the first sound outlet is connected to the acoustic cavity 11 through the connecting cavity, so that the sound can propagate in the connecting cavity and the acoustic cavity 11 in turn, thereby further increasing the number of reflections of the sound when propagating in the earphone, and further optimizing the acoustic effect of the sound, that is, further enhancing the playback effect of the earphone.

[0049] As an optional implementation, see Figure 1 and Figure 2 , the second shell portion 102 is in the shape of a hook.

[0050] The second housing portion 102 is shaped like a hook, and the shape of the second housing portion 102 can match the contour of a human ear.

[0051] In the embodiment of the present application, the second shell portion 102 is shaped like a hook, so that the earphones can be worn on the human ear more conveniently, further enhancing the user experience.

[0052] As an optional implementation, the second housing portion 102 is detachably connected to the first housing portion 101 .

[0053] In the embodiment of the present application, the second shell portion 102 is detachably connected to the first shell portion 101, so that the second shell portion 102 can be easily disassembled from the first shell portion 101, thereby facilitating the repair or replacement of the first shell portion 101, the second shell portion 102, the parts in the first shell portion 101 or the parts in the second shell portion 102, thereby improving repair efficiency and reducing repair costs.

[0054] As an optional embodiment, the cross-sectional area of ​​the end of the second housing portion 102 away from the first housing portion 101 is larger than the cross-sectional area of ​​the end of the second housing portion 102 close to the first housing portion 101 .

[0055] In which, that is, along the direction from the end of the second shell portion 102 away from the first shell portion 101 to the end of the second shell portion 102 close to the first shell portion 101, the cross-sectional area can gradually decrease, that is, the second shell portion 102 can be trumpet-shaped, and the cross-section of the end of the second shell portion 102 away from the first shell portion 101 is larger, and the cross-section of the end close to the first shell portion 101 is smaller.

[0056] In the embodiment of the present application, since the cross-sectional area of ​​the end of the second shell portion 102 away from the first shell portion 101 is larger than the cross-sectional area of ​​the end of the second shell portion 102 close to the first shell portion 101, when sound propagates in the second shell portion 102, the loudness of the sound can be increased, thereby further enhancing the effect of sound propagation in the second shell portion 102.

[0057] An embodiment of the present application further provides an electronic device assembly, comprising an electronic device and the earphones as described in the above embodiment, wherein the electronic device is wirelessly connected to the earphones, or the electronic device is connected to the earphones via a connecting wire.

[0058] Among them, if the electronic device is connected to the headset wirelessly, then the headset is a wireless headset; if the electronic device is connected to the headset via a connecting cable, then the headset can be called a wired headset, and the headset and the connecting cable can be detachably connected.

[0059] It should be noted that since the electronic device component provided in the embodiment of the present application includes the headphones in the above embodiment, it has the same beneficial technical effects as the above embodiment, and the specific structure of the headphones can refer to the corresponding description in the above embodiment, and will not be repeated here.

[0060] The above is a preferred implementation of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
