In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] In the related art, in order to be able to produce sound to pass into the ear of the user, the earphone is usually internally provided with a loudspeaker and a mainboard. The loudspeaker and the mainboard will generate electromagnetic signals in the working process, and the electromagnetic signals will diffuse in the earphone along the periphery. The electromagnetic signals of the loudspeaker can be transmitted to the mainboard, and the electromagnetic signals of the mainboard can also be transmitted to the loudspeaker, thereby causing the mainboard and the mainboard to generate electromagnetic interference phenomenon, so that the mainboard and the loudspeaker appear abnormal in the working process, affecting the experience of the user.

[0035] The first shell 100 is internally provided with a partition 200 which is arranged obliquely with the loudspeaker 300, so as to separate the loudspeaker 300 and the mainboard 400 in the first cavity 100c and the second cavity 100d, thereby reducing the electromagnetic interference phenomenon between the mainboard 400 and the loudspeaker 300, and increasing the experience of the user.

[0036] Specifically, the present application provides an earphone, please refer to Figure 1 and Figure 2 , the earphone comprises a first shell 100, a partition 200, a loudspeaker 300 and a mainboard 400. The first shell 100 is formed with a mounting cavity 100a and a sound hole 100b, and the sound hole 100b is respectively communicated with the mounting cavity 100a and the outside. The partition 200 is installed in the first shell 100 and separates the mounting cavity 100a into a first cavity 100c and a second cavity 100d, and the sound hole 100b is respectively communicated with the first cavity 100c and the outside. The loudspeaker 300 is located in the first cavity 100c, and the mainboard 400 is located in the second cavity 100d, and the mainboard 400 is electrically connected with the loudspeaker 300. The partition 200 and the loudspeaker 300 are arranged obliquely with each other.

[0037] The loudspeaker 300 can also be called a speaker, and the loudspeaker 300 is the core component in the earphone, which is responsible for converting the received electrical signals into sound. The loudspeaker 300 usually includes a magnet, a voice coil and a diaphragm. When audio current passes through the voice coil, the voice coil will be subjected to force in the magnetic field generated by the magnet, and this force will drive the diaphragm to vibrate, thereby generating sound waves in the air and transmitting to the human ear, so that the user can hear the sound.

[0038] The mainboard 400 refers to the architecture for controlling the basic functions of the earphone such as playing, pausing, volume adjustment, etc. The circuit on the mainboard 400 is responsible for processing the received audio signals, including amplification, filtering, equalization, etc., to ensure the clarity and fidelity of the audio signals. Exemplarily, the mainboard 400 can be a PCBA (printed circuit board assembly), and the mainboard 400 usually includes multiple circuit boards.

[0039] It can be understood that the loudspeaker 300 and the isolation piece 200 each have a large face, and the surface area of the large face is much larger than that of other faces. The mutual inclination arrangement of the isolation piece 200 and the loudspeaker 300 means that the plane in which the large face of the loudspeaker 300 is located intersects the plane in which the large face of the isolation piece 200 is located.

[0040] Exemplarily, the isolation piece 200 is in the shape of a plate structure.

[0041] In the scheme of the embodiment of the present application, the isolation piece 200 is installed in the first shell 100 and divides the mounting cavity 100a into a first cavity 100c and a second cavity 100d. The loudspeaker 300 and the mainboard 400 are respectively located in the first cavity 100c and the second cavity 100d. The isolation piece 200 located between the loudspeaker 300 and the mainboard 400 can isolate electromagnetic signals to a certain extent, thereby reducing the electromagnetic interference phenomenon between the loudspeaker 300 and the mainboard 400. Furthermore, the mutual inclination arrangement of the isolation piece 200 and the loudspeaker 300 can further reduce the electromagnetic signals of the loudspeaker 300 from penetrating the isolation piece 200 to affect the mainboard 400, thereby reducing the mutual inductance phenomenon between the loudspeaker 300 and the mainboard 400. Furthermore, the loudspeaker 300 vibrates to generate sound waves that propagate to the isolation piece 200. The mutual inclination arrangement of the isolation piece 200 and the loudspeaker 300 can reflect the sound waves at a certain angle, thereby reducing the standing waves in the first cavity 100c and reducing the decline in sound quality caused by the earphone.

[0042] It can be understood that the mutual inclination arrangement of the isolation piece 200 between the loudspeaker 300 and the mainboard 400 can reduce the electromagnetic interference phenomenon between the loudspeaker 300 and the mainboard 400 to a certain extent. The diffusion of electromagnetic signals in the earphone gradually attenuates with distance, and therefore the distance between the loudspeaker 300 and the mainboard 400 affects the strength of electromagnetic interference.

[0043] In an embodiment, as shown in Figure 2 , the distance between the loudspeaker 300 and the mainboard 400 ranges from 3 mm to 7 mm.

[0044] It should be noted that the distance between the loudspeaker 300 and the mainboard 400 refers to the shortest straight-line distance between the loudspeaker 300 and the mainboard 400. Exemplarily, the distance between the loudspeaker 300 and the mainboard 400 is 3 mm, 4 mm, 5 mm, 6 mm, or 7 mm.

[0045] It can be understood that the distance between the loudspeaker 300 and the mainboard 400 can be measured by a ruler under normal temperature and pressure.

[0046] Exemplarily, the distance between the loudspeaker 300 and the mainboard 400 is shown as the dimension D1 in Figure 2 .

[0047] In the scheme of the embodiment of the application, the distance between the loudspeaker 300 and the mainboard 400 is within a proper range, which can reduce the overall volume of the earphone to a certain extent on the basis that the electromagnetic signals generated by the loudspeaker 300 and the mainboard 400 have little influence on each other, and the structure inside the earphone is relatively compact.

[0048] It can be understood that other embodiments of the application do not limit the distance between the loudspeaker 300 and the mainboard 400.

[0049] It can be understood that after the electromagnetic signal generated by the loudspeaker 300 contacts the isolation piece 200, part of the electromagnetic signal will diffuse to the mainboard 400 through the isolation piece 200, and part of the electromagnetic signal will be reflected by the isolation piece 200. The angle between the isolation piece 200 and the loudspeaker 300 will affect the degree of reflection of the electromagnetic signal by the isolation piece 200.

[0050] In an embodiment, referring to Figure 2 , the range of the included angle formed by the large surface of the isolation piece 200 and the large surface of the loudspeaker 300 is 5°-30°.

[0051] Exemplarily, the size of the included angle between the large surface of the isolation piece 200 and the large surface of the loudspeaker 300 is 5°, 10°, 15°, 20°, 25° or 30°. It can be understood that the included angle between the large surface of the isolation piece 200 and the large surface of the loudspeaker 300 can be measured by a protractor under normal temperature and pressure.

[0052] Exemplarily, the included angle formed by the large surface of the isolation piece 200 and the large surface of the loudspeaker 300 is shown as an angle θ1 in Figure 2 .

[0053] In the scheme of the embodiment of the application, the included angle between the large surface of the isolation piece 200 and the large surface of the loudspeaker 300 is within a proper range, which can reflect more sound waves generated by the loudspeaker 300 on the basis of reducing the generation of standing waves, and also can reduce the space occupied by the isolation piece 200 inside the first shell 100, so that the loudspeaker 300, the isolation piece 200 and the mainboard 400 can be relatively compact.

[0054] It can be understood that other embodiments of the application do not limit the size of the included angle formed by the large surface of the isolation piece 200 and the large surface of the loudspeaker 300.

[0055] It can be understood that for a wireless earphone, a battery 700 is usually arranged inside the earphone to supply power to the electronic elements inside the earphone, and the battery 700 will also generate electromagnetic signals during the working process, which may affect the loudspeaker 300 and thus affect the sound quality of the earphone.

[0056] In an embodiment, referring to Figure 1The first shell 100 further forms a tuning hole 100e in an elliptical or track shape. The track shape is formed by connecting a rectangle with two semicircles, and the straight line segments of the two semicircles are located on the side facing the rectangle. The elliptical or track shape of the tuning hole 100e can enhance the bass effect of the earphone and increase the sound quality of the earphone.

[0057] For example, the opening area of the tuning hole 100e is greater than 9mm 2 and less than 30mm 2 The width of the tuning hole 100e ranges from 0.8mm to 2.0mm, and the length ranges from 6mm to 12mm. The size of the tuning hole 100e in the appropriate range can achieve a larger earphone ventilation amount and a larger amplitude, and can also alleviate the problem of affecting the appearance of the earphone due to the larger area of the tuning hole 100e.

[0058] In an embodiment, referring to Figure 1 and Figure 2 The earphone further comprises an ear hook 500, a second shell 600 and a battery 700. The ear hook 500 is connected to the second shell 600 and the first shell 100 respectively, the second shell 600 is arranged apart from the first shell 100, and the battery 700 is installed in the interior of the second shell 600.

[0059] The ear hook 500 refers to a structure for enabling the earphone to be more stably worn on the ear of a user, and enabling the sound generating part to be connected to the battery 700.

[0060] In the scheme of the embodiment of the application, the earphone further comprises an ear hook 500 and a second shell 600. The ear hook 500 is connected to the second shell 600 and the first shell 100 respectively. The ear hook 500 can separate the first shell 100 and the second shell 600 from each other, so that the distance between the loudspeaker 300 and the battery 700 is far. The electromagnetic effect generated by the battery 700 during power supply has less influence on the loudspeaker 300, thereby reducing the influence of the battery 700 on the sound quality of the earphone.

[0061] It can be understood that the ear hook 500 is connected to the first shell 100 and the second shell 600 respectively. During the wearing of the earphone by the user, the ear hook 500 inevitably contacts the ear of the user. The material of the ear hook 500 has a great influence on the wearing comfort of the earphone.

[0062] In an embodiment, the ear hook 500 is made of a material capable of elastic deformation. The ear hook 500 is capable of elastic deformation, and in the process of wearing the earphone, the ear hook 500 can be deformed according to the shape of the user's ear, so that the shape of the whole earphone can fit the user's ear, increasing the comfort of the earphone. Furthermore, the first shell 100 and the second shell 600 can clamp the user's ear under the action of the ear hook 500 to fix the earphone, and the ear hook 500 can adjust the distance between the first shell 100 and the second shell 600, so that the earphone can adapt to the ears of different users, and the adaptability of the earphone is higher.

[0063] Exemplarily, the material of the ear hook 500 is silicone or TPU (Thermoplastic Urethane, thermoplastic polyurethane elastomer).

[0064] It can be understood that other embodiments of the present application do not limit the material of the ear hook 500.

[0065] In an embodiment, please refer to Figure 2 , the ear hook 500 includes a third shell 510 and an elastic member 520, the third shell 510 is connected to the first shell 100, the elastic member 520 is wrapped around the third shell 510, and the third shell 510 and the first shell 100 together enclose a second cavity 100d. The material of the elastic member 520 is capable of elastic deformation.

[0066] In an embodiment, please refer to Figure 2 , the distance between the battery 700 and the loudspeaker 300 ranges from 5mm to 20mm.

[0067] It should be noted that the distance between the battery 700 and the loudspeaker 300 refers to the shortest straight-line distance between the battery 700 and the loudspeaker 300.

[0068] Exemplarily, the distance between the battery 700 and the loudspeaker 300 is 5mm, 10mm, 15mm or 20mm.

[0069] It can be understood that the distance between the battery 700 and the loudspeaker 300 can be measured by a ruler under normal temperature and pressure.

[0070] Exemplarily, the distance between the battery 700 and the loudspeaker 300 is shown as Figure 2 the middle size D2.

[0071] In the scheme of the embodiment of the present application, the distance between the battery 700 and the loudspeaker 300 within a suitable range can not only reduce the degree of electromagnetic interference caused by the battery 700 to the loudspeaker 300, but also make the arrangement of the electronic elements inside the earphone more compact, and the overall volume of the earphone smaller.

[0072] It can be understood that other embodiments of the present application do not limit the distance between the battery 700 and the loudspeaker 300.

[0073] In an embodiment, referring to Figure 3 The earphone further comprises an antenna 800, the antenna 800 is arranged inside the ear hook 500, and the distance between the antenna 800 and the mainboard 400 ranges from 5 mm to 8 mm.

[0074] Exemplarily, the antenna 800 is an LDS (Laser-Direct-structuring) antenna 800 technology. The antenna 800 is laser-radiated on the surface of the third shell 510 facing the elastic piece 520.

[0075] The distance between the antenna 800 and the mainboard 400 refers to the shortest straight-line distance between the antenna 800 and the mainboard 400. Exemplarily, the distance between the antenna 800 and the mainboard 400 is 5 mm, 6 mm, 7 mm or 8 mm.

[0076] It can be understood that the distance between the antenna 800 and the mainboard 400 can be measured by a ruler under normal temperature and pressure.
