DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0036] Referring to Figures 1 to 3 A kind of earphone 100 provided for the embodiment of the application, earphone 100 includes shell 1, movement core 2, first moving iron assembly 3 and second moving iron assembly 4, shell 1 has sound hole 11, movement core 2 is arranged in the inside of shell 1, and movement core 2 and shell 1 define front cavity 201, rear cavity 202 and side cavity 203, front cavity 201 is located at the side of movement core 2 towards sound hole 11, front cavity 201 also communicates with sound hole 11, side cavity 203 is located at the side of front cavity 201, and side cavity 203 communicates with front cavity 201, first moving iron assembly 3 is arranged in front cavity 201, second moving iron assembly 4 is arranged in side cavity 203.

[0037] Optionally, earphone 100 is an electronic device that can receive audio signals and convert them into sound, shell 1 is used as the outer protective structure of earphone 100, shell 1 is located at the outermost of earphone 100, and shell 1 is provided with sound hole 11, which can guide the sound generated inside earphone 100 out of sound hole 11, and the inside of shell 1 can also form a containing space for installing other components of earphone 100.

[0038] Movement core 2 can be installed in the inside of shell 1, shell 1 can prevent movement core 2 from being damaged by collision, and movement core 2 and shell 1 can define front cavity 201, rear cavity 202 and side cavity 203, front cavity 201 is located at the side of movement core 2 towards sound hole 11, and front cavity 201 also communicates with sound hole 11, so that the sound generated by movement core 2 in front cavity 201 can be transmitted out of earphone 100 from sound hole 11, front cavity 201 plays an important role in the transmission and tuning of sound, and side cavity 203 is located at the side of front cavity 201 and communicates with front cavity 201, so that the sound can be more evenly distributed in the sound generating area of earphone 100.

[0039] First moving iron assembly 3 is arranged in front cavity 201, and second moving iron assembly 4 is arranged in side cavity 203, sound is generated in front cavity 201 by first moving iron assembly 3, and sound is generated by the combination of first moving iron assembly 3 and movement core 2, which is beneficial to fully exert the excellent mid-high frequency performance of first moving iron assembly 3, and further, sound is generated in side cavity 203 by second moving iron assembly 4, second moving iron assembly 4 compresses the air in side cavity 203 to front cavity 201, and first moving iron assembly 3 and second moving iron assembly 4 jointly press the air in front cavity 201 out of sound hole 11 to generate sound, so that first moving iron assembly 3 and second moving iron assembly 4 cooperate to generate sound, which can improve the mid-high frequency sound performance of earphone 100 and improve the listening effect.

[0040] Referring to Figure 2 And Figure 3 In some embodiments, earphone 100 can include at least two first moving iron assemblies 3, and the two first moving iron assemblies 3 are arranged side by side in front cavity 201.

[0041] Optionally, two first moving iron assemblies 3 are arranged side by side in the front cavity 201, so that the two first moving iron assemblies 3 can sound at the same time in the front cavity 201, using multiple first moving iron assemblies 3 can widen the frequency response range of the earphone 100, improve the resolving power and detail performance of the sound, and multiple first moving iron assemblies 3 can process different frequency bands of sound respectively, which helps to enhance the stereo sense and positioning accuracy of the sound.

[0042] Please refer to Figure 2 In some embodiments, a waterproof mesh 12 is arranged at the sound outlet hole 11, and the first moving iron assembly 3 is connected to the waterproof mesh 12.

[0043] Optionally, the waterproof mesh 12 can be connected to the sound outlet hole 11, and the waterproof mesh 12 can cover the sound outlet hole 11. The waterproof mesh 12 can prevent water, dust and other impurities from entering the inside of the earphone 100 from the sound outlet hole 11, thereby protecting the movement 2 inside the earphone 100 from damage, which is crucial for maintaining the normal operation of the earphone 100 and prolonging the service life.

[0044] It should be noted that the waterproof mesh 12 can be directly pasted at the sound outlet hole 11 by glue or double-sided tape. This method is simple and fast, but attention should be paid to the selection of glue to ensure that the glue does not have a negative impact on the sound quality of the earphone 100. A buckle structure can also be provided on the shell 1 to fix the waterproof mesh 12, so that the waterproof mesh 12 is more firmly connected to the sound outlet hole 11 and is not easy to fall off. In addition, the waterproof mesh 12 can also be installed by screwing, which is relatively complex but can provide more reliable fixing effect.

[0045] The first moving iron assembly 3 can be directly pasted on the waterproof mesh 12 by glue, which can prevent the first moving iron assembly 3 from loosening or falling off during use, and the waterproof mesh 12 can also protect the first moving iron assembly 3 from water and dust erosion, thereby prolonging the service life of the first moving iron assembly 3.

[0046] Please refer to Figure 2 In some embodiments, the projection area of the first moving iron assembly 3 along the axis of the sound outlet hole 11 has a ratio a with the projection area of the sound outlet hole 11 along its own axis, and a satisfies: 1 / 2≥a≥1 / 4.

[0047] It can be understood that the projection of the waterproof mesh 12 along the axis of the sound outlet hole 11 needs to cover the projection of the sound outlet hole 11 along its own axis, so that the waterproof mesh 12 can cover the sound outlet hole 11, and the first moving iron assembly 3 is connected to the waterproof mesh 12. Then, the projection area of the first moving iron assembly 3 along the axis of the sound outlet hole 11 has a proportional relationship with the projection area of the sound outlet hole 11 along its own axis.

[0048] Specifically, when the ratio a of the projection area of the first moving iron assembly 3 along the axial direction of the sound hole 11 to the projection area of the sound hole 11 along its own axial direction satisfies: 1 / 2≥a≥1 / 4, two first moving iron assemblies 3 can be reasonably installed in the area where the sound hole 11 is located, and the two first moving iron assemblies 3 can jointly improve the high-frequency sound performance of the earphone,

[0049] However, when the ratio a is greater than 1 / 2, it means that one first moving iron assembly 3 occupies at least 1 / 2 of the area of the sound hole 11, which makes it difficult to install two first moving iron assemblies 3 in the area where the sound hole 11 is located. In addition, the first moving iron assembly 3 occupies too much area of the sound hole 11, which also leads to poor sound output effect.

[0050] When the ratio a is less than 1 / 4, it means that one first moving iron assembly only occupies a very small part of the area of the sound hole 11, which leads to the area of the sound hole 11 being too large relative to the first moving iron assembly 3. The sound hole 11 is too large, which can cause sound leakage and affect the sound output effect of the earphone 100. Therefore, when the ratio a satisfies: 1 / 2≥a≥1 / 4, the high-frequency sound performance of the earphone can be further improved.

[0051] Please refer to Figure 3 In some embodiments, the first moving iron assembly 3 includes a first housing 31 and a first diaphragm disposed in the first housing 31, and the second moving iron assembly 4 includes a second housing 41 and a second diaphragm disposed in the second housing 41. The axial center line of the first diaphragm intersects the axial center line of the second diaphragm.

[0052] Optionally, the first housing 31 is usually made of a solid material such as metal or plastic, so that the first housing 31 has sufficient structural strength to accommodate and protect the first diaphragm. The first diaphragm is usually made of a lightweight material such as a metal foil or a plastic film, so that the first diaphragm has good response speed and sensitivity. The first diaphragm is disposed towards the sound hole 11, so that the sound generated by the first diaphragm can be transmitted from the sound hole 11.

[0053] The second housing 41 is similar to the first housing 31, and the second housing 41 can accommodate and protect the second diaphragm. The material and structure of the second diaphragm can be the same as those of the first diaphragm. The second diaphragm can also generate sound, and the axial center line of the second diaphragm intersects the axial center line of the first diaphragm, so that the vibration direction of the second diaphragm can be towards the first diaphragm. Therefore, the sound generated by the second diaphragm can be transmitted in the direction of the first diaphragm, and the sound generated by the second diaphragm and the sound generated by the first diaphragm can be mixed at the sound hole 11, which can enhance the sound effect of the sound finally emitted from the sound hole 11.

[0054] Please refer to Figure 3In some embodiments, the first housing 31 has a first sound outlet 311, which is arranged towards the sound hole 11, and the second housing 41 has a second sound outlet 411, which is arranged towards the direction where the first moving coil assembly 3 is located and which is in communication with the front cavity 201.

[0055] Optionally, the first sound outlet 311 is an opening on the first housing 31, which is used to transmit the sound generated by the vibration of the first diaphragm, and the first sound outlet 311 is arranged towards the sound hole 11, so that the sound can be directly transmitted from the first moving coil assembly 3 to the user's ear, thus the sound is clearer.

[0056] The second sound outlet 411 is an opening on the second housing 41, which is used to transmit the sound generated by the vibration of the second diaphragm, and the second sound outlet 411 is arranged towards the direction where the first moving coil assembly 3 is located, and the second sound outlet 411 is also in communication with the front cavity 201, so that the sound generated by the second diaphragm can be transmitted into the front cavity 201, and the sound generated by the second diaphragm can be superimposed or mixed with the sound generated by the first diaphragm, thus creating a more rich and complex sound effect.

[0057] Please refer to Figure 2 and Figure 3 In some embodiments, the core 2 can include a first speaker 21 and a second speaker 22, the first speaker 21 can be arranged corresponding to the sound hole 11, and the first speaker 21 and the shell 1 define the front cavity 201, the second speaker 22 is arranged on the side of the first speaker 21 away from the sound hole 11, and the second speaker 22 is arranged spaced apart from the first speaker 21, and the second speaker 22 also cooperates with the first speaker 21 to form the rear cavity 202 of the first speaker 21.

[0058] Optionally, the first speaker 21 and the second speaker 22 are integrated on the core 2, wherein the first speaker 21 serves as a sound emitting component of the earphone 100, can be arranged corresponding to the sound hole 11, and the sound generated by the first speaker 21 can be transmitted to the user's ear through the sound hole 11, while the second speaker 22 is arranged on the side of the first speaker 21 away from the sound hole 11, and the second speaker 22 is arranged in a spaced manner with the first speaker 21, so that the first speaker 21 and the second speaker 22 form a series double speaker structure, which can effectively reduce the interference between them and ensure the clarity and quality of audio output, and the second speaker 22 is not only an ordinary audio output device, but also a noise reduction component. The second speaker 22 and the first speaker 21 jointly form the back cavity 202 of the first speaker 21, and the second speaker 22 can detect environmental noise in real time and generate reverse sound waves to offset the environmental noise, which helps to further optimize the noise reduction performance of the earphone 100 and makes the sound emitted by the earphone 100 more pure and clear.

[0059] In some embodiments, the sound emitting frequency of the first speaker 21 is higher than that of the second speaker 22. The first speaker 21 serves as an output audio component, and the sound emitting frequency of the first speaker 21 is in a higher frequency range, such as the mid-high to high frequency part in the audible range of human ear (usually from several hundred hertz to several thousand hertz or higher). The high frequency first speaker 21 can clearly reproduce the high frequency details in the music, such as the clarity and brightness of the human voice, the overtones and details of the musical instruments, etc. The second speaker 22 serves as a noise reduction component, and does not need to output audio signals like the first speaker 21. The second speaker 22 offsets the noise in the environment by generating sound waves opposite to the noise. Therefore, the sound emitting frequency of the first speaker 21 is higher than that of the second speaker 22.

[0060] Please refer to Figure 2 and Figure 3 In some embodiments, the core 2 further comprises a support 23 arranged between the first speaker 21 and the second speaker 22, the support 23 is used to support at least the second speaker 22, and the support 23, together with the first speaker 21 and the second speaker 22, forms the back cavity 202.

[0061] Specifically, one end of the support 23 is arranged opposite to the first speaker 21, and the other end of the support 23 is used to support the second speaker 22, so that the first speaker 21, the support 23 and the second speaker 22 can be arranged in sequence along the same straight line, thereby forming a series double speaker structure. The series double speaker structure not only reduces the sound interference between the first speaker 21 and the second speaker 22, but also enhances the stability of the overall structure.

[0062] In addition, the support 23 not only supports and fixes, but also cooperates with the first speaker 21 and the second speaker 22 to form a rear cavity 202 of the first speaker 21, which is crucial to sound quality. The rear cavity 202 can optimize the sound propagation path and reduce sound reflection and interference, thereby improving sound quality performance. Through the close cooperation of the support 23 and the double speakers, the rear cavity 202 is more reasonable and efficient, bringing better sound quality to the earphone 100.

[0063] Referring to Figure 3 In some embodiments, the earphone 100 further comprises a sound receiving part 5, which is arranged on the support 23 and located in the side cavity 203.

[0064] Optionally, the sound receiving part 5 is a component in the earphone 100 for receiving external sound (such as the user's voice), for capturing sound and converting it into an electrical signal. The sound receiving part 5 usually contains one or more microphones, and is arranged on the support 23 and located in the side cavity 203. The side cavity 203 can provide a certain sound insulation effect, reducing the interference of external noise on the sound receiving part 5, so that the sound receiving part 5 can clearly capture the user's voice in a noisy environment.

[0065] Referring to Figure 4 In some embodiments, the earphone 100 can include an ear hook 6 and a battery compartment 7. One end of the ear hook 6 is connected to the shell 1, and the other end of the ear hook 6 is connected to the battery compartment 7.

[0066] Optionally, the battery compartment 7 is provided with a battery, and the ear hook 6 can connect the battery compartment 7 and the shell 1. The inside of the ear hook 6 is provided with a connection wire harness, one end of which is electrically connected to the battery, and the other end of which is electrically connected to the core 2, so that the battery can power the core 2. When the earphone 100 is worn on the user's ear, the ear hook 6 can be hung on the user's auricle, and the shell 1 and the battery compartment 7 can hold the user's earlobe, so that the earphone 100 can be stably worn on the user's ear.

[0067] In a second aspect, the embodiments of the present application provide an earphone assembly, which can include an earphone 100 and a charging box. The charging box is used to accommodate the earphone 100 to charge the earphone 100.

[0068] Optionally, the number of earphones 100 is, for example, two, and two charging spaces that can be connected or not connected are formed in the charging box to accommodate two earphones 100 respectively. The beneficial effects of the earphone assembly in the present application are the same as those of the earphone 100 in the present application, which will not be repeated here.
