Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bone conduction earphones, in particular to an in-ear bone conduction wireless earphone. Background Art
[0002] With the rapid development of modern technology and consumers' increasing demand for sound quality, headphone technology is undergoing unprecedented innovation. Traditional headphones primarily rely on the principle of air conduction, whereby sound is transmitted through the air into the external auditory canal, where it is received by the eardrum and converted into nerve signals that are transmitted to the brain. However, this transmission method has certain limitations in sound quality, such as susceptibility to ambient noise interference and high sound distortion.
[0003] To overcome these shortcomings, bone conduction technology emerged and has gradually matured. Bone conduction technology is an innovative way to transmit sound, using the human skeleton as a medium for sound transmission, transmitting sound vibrations directly to the inner ear, bypassing the outer and middle ear. Because solid matter (bone) transmits sound more efficiently than air and with lower distortion, bone conduction headphones can provide a clearer, purer sound quality experience, making them particularly suitable for music listening and daily calls.
[0004] However, despite significant advancements in sound quality, bone conduction technology still faces challenges in practical application. In particular, in noisy environments, traditional bone conduction headphones, which don't effectively seal the ear canal, allow noise to enter the inner ear directly through the external auditory canal, severely degrading the user's listening experience. This issue limits the widespread use of bone conduction headphones in various everyday situations. Utility Model Content

[0020] The present invention provides an in-ear bone conduction wireless headset 100.
[0021] See also Figures 1 to 3 In one embodiment of the present invention, the in-ear bone conduction wireless headset 100 includes a shell 1 and a moving iron sound unit 4. An in-ear portion 2 is formed at one end of the shell 1, and a vibration portion 21 is formed at the end of the in-ear portion 2 away from the shell 1. The shell 1 is provided with a cavity 11; the moving iron sound unit 4 is arranged in the cavity 11.
[0022] In the technical solution of the present invention, the in-ear part 2 of the earphone is inserted into the human ear 200, and the vibration part 21 is in contact with the auricle bone 210 of the human ear 200. The moving iron sound unit 4 generates sound waves through the excitation of the electrical signal. The emitted sound waves are first transmitted to the cavity 11 of the shell 1. After passing through the cavity 11, the sound waves are transmitted to the vibration part 21. The vibration part 21 effectively transmits the audio signal through the auricle bone 210 and bypasses the outer ear and middle ear to the inner ear. The in-ear part 2 can comfortably fit the outer ear of the human ear 200, forming an effective closure on the ear canal 220 to prevent noise from the external environment from entering the ear, so as to provide good sound insulation effect and sound quality experience. This design can effectively block external noise while enhancing the sound output of the earphones and improving the user's auditory experience.
[0023] To improve sound quality and user experience, please refer to Figure 2In one embodiment of the present invention, the in-ear bone conduction wireless headset 100 includes a front cavity baffle 3, which is connected to the inner circumferential wall of the cavity 11, and the moving iron sound unit 4 is passed through the front cavity baffle 3. The front cavity baffle 3 is connected to the inner circumferential wall of the cavity 11, effectively supporting the moving iron sound unit 4, enabling the moving iron sound unit 4 to be better fixed inside the headset, reducing the impact of the headset on the moving iron sound unit 4 when it moves, shakes, or is impacted by external forces, and ensuring the normal operation and service life of the moving iron sound unit 4; the moving iron sound unit 4 generates sound waves through the excitation of electrical signals, and the emitted sound waves are first transmitted to the cavity 11 of the housing 1. The design of the cavity 11 is to optimize the propagation of sound waves, ensure the reflection and enhancement of sound waves in space, thereby improving the overall Sound quality: After the sound waves pass through the cavity 11, they are transmitted to the vibration part 21. The vibration part 21 uses bone conduction technology to convert the sound waves into vibrations, which are transmitted to the inner ear through the auricle bone 210; the dynamic iron sound unit 4 is small in size and can provide excellent audio performance, especially in the high and medium frequencies. The sound quality is clear and delicate. The compact design reduces the overall weight of the headset and improves the user's wearing experience, especially when used for a long time, reducing the burden on the ears. It not only provides flexibility and portability in design, but also achieves significant improvements in sound quality and user experience.
[0024] More specifically, see Figure 2 In one embodiment of the present invention, the front cavity baffle 3 separates the cavity 11 into a first cavity 111 and a second cavity 112. Part of the structure of the moving iron sound unit 4 is located in the first cavity 111, and the other part of the structure of the moving iron sound unit 4 is located in the second cavity 112. The front cavity baffle 3 separates the cavity 11 into two independent cavities. Through this separation design, acoustic phenomena such as sound wave reflection, resonance and attenuation in different cavities can be realized, thereby improving the overall sound quality performance of the earphones. The design of the front cavity baffle 3 can also reduce the standing wave effect in the cavity, making the performance of low-frequency and high-frequency sounds more balanced. By placing part of the structure of the moving iron sound unit 4 in two cavities, the characteristics of different cavities can be used to process sounds of different frequencies separately, achieving a better frequency division effect, so that high, medium and low-frequency sounds can be presented more accurately.
[0025] To improve the support stability of the moving iron sound unit 4, please refer to Figure 2In one embodiment of the present invention, the in-ear bone conduction wireless earphone 100 includes a support column 5, the two ends of which are connected to the side walls of the cavity 11 and the balanced armature sound unit 4, respectively. The support column 5 connects the side walls of the cavity 11 and the balanced armature sound unit 4, helping to enhance the overall structural stability of the earphone. The support column 5 provides a solid support point, preventing displacement or vibration during use, thereby ensuring consistent sound quality. The presence of the support column 5 optimizes the propagation path of sound waves and reduces sound loss during transmission. By rationally designing the position and shape of the support column 5, the reflection and resonance of sound waves can be further improved. The support column 5 acts as a shock absorber, absorbing external impact and vibration, reducing interference with the balanced armature sound unit 4. This helps improve the clarity and refinement of sound quality, especially in the low-frequency band. Using the support column 5 as a connector simplifies the assembly process of the earphone. This design ensures a more secure connection between different components, while also facilitating production and maintenance.
[0026] Further, see Figure 2 In one embodiment of the present invention, the earphone includes two support columns 5, and each support column 5 is arranged in the cavity 11 at intervals along the length direction of the moving iron sound unit 4. The provision of two support columns 5 can more evenly distribute the vibration and load generated by the moving iron sound unit 4, reduce the pressure borne by a single support column 5, and thus enhance the overall structural stability of the earphone; the spacing design of the support columns 5 helps to form a better sound wave propagation path. By optimizing the distance between the support columns 5, the reflection and resonance of the sound waves in the cavity 11 can be adjusted, thereby improving the sound quality performance of the earphone; the spacing setting of the support columns 5 can reduce the resonance effect caused by vibration, which helps to improve the clarity and delicacy of the audio, especially in the high-frequency band.
[0027] To improve the wearing stability of the headset, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the vibration part 21 is provided protruding from the outer peripheral wall of the earphone 2. The protruding vibration part 21 can change the output direction of the sound, thereby reducing the reflection and scattering of the sound inside the earphone, improving the transmission efficiency of the sound, allowing the user to hear the details of the sound more clearly, and enhancing the sense of presence and reality of the sound. The protruding design of the vibration part 21 helps to enhance the output of low-frequency sound, making the bass part fuller and more powerful, and improving the layering of the sound quality; the protruding vibration part 21 can better fit the contour of the ear, increase the friction between the earphone and the ear, thereby improving the wearing stability. Even if the user performs some exercises or shakes his head, the earphone is not easy to fall off, ensuring the convenience and reliability of use.
[0028] For easy fitting, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the cross-sectional area of the housing 1 is larger than the cross-sectional area of the ear inlet 2 in the length direction of the in-ear bone conduction wireless earphone 100. The larger cross-sectional area of the housing 1 helps to form a better acoustic cavity, optimize the resonance effect of sound waves, and thus improve the sound quality, especially in terms of low-frequency sound effects; the larger space of the housing 1 can effectively enhance the efficiency of sound conduction, reduce the loss of sound waves during propagation, and improve the overall audio clarity; the design of the housing 1 prevents the earphone from completely entering the ear canal 220 when worn, making it easy for the user to remove it, avoiding embarrassment or discomfort when removing it, and the fit between the ear inlet 2 and the ear canal 220 can effectively block some external noise, thereby improving the user's listening experience; the larger cross-sectional area of the housing 1 can accommodate more components, such as batteries, drive units, etc., which helps to improve the overall performance and battery life of the earphones. The larger space of the housing 1 also helps to dissipate heat, prevent the device from overheating, and further improve the durability and stability of the earphones.
[0029] See also Figure 1 In one embodiment of the present invention, an arc transition section 22 is formed at the end of the ear inlet 2 away from the housing 1. The design of the arc transition section 22 can reduce the presence of sharp edges, allowing the earphone to fit more closely to the ear canal 220 when worn, significantly improving comfort and making it suitable for long-term wear. The arc shape can better fit the contours of the ear canal 220, enhancing the sealing performance of the earphone, helping to block external noise and improving the clarity and purity of the audio. The arc transition section 22 can reduce pressure on the ear canal 220 when worn, improving the user experience and reducing the possibility of ear pain or discomfort.
[0030] To improve wearing comfort, in one embodiment of the present invention, the material of the end of the ear-entry portion 2 away from the housing 1 is a soft material. Soft materials can better adapt to the shape of the ear canal 220, reduce friction and pressure, make wearing more comfortable, and are particularly suitable for long-term use; soft materials have good flexibility and can form a good sealing effect when worn, reduce interference from external noise, and improve sound clarity; soft materials can effectively disperse the pressure of the earphone on the ear canal 220, reduce discomfort or fatigue that may occur during use, and enhance the overall user experience; high-quality soft materials are not only durable, but also can adapt to the ear canal 220 structure of different users, providing a more personalized wearing experience; soft materials generally have good cleaning properties, making it easier for users to keep the earphones clean during daily use; soft materials have a certain grip, which can effectively prevent the earphones from slipping when worn and improve wearing stability.
[0031] Furthermore, in one embodiment of the present invention, the in-ear bone conduction wireless earphones 100 include a soft plug that fits over the in-ear portion 2. The soft plug is made of a soft material that can better adapt to the shape of the user's ear canal 220, providing a more comfortable wearing experience, especially suitable for prolonged use. The soft plug helps to form a good seal, reducing interference from external noise, thereby improving audio clarity and the overall listening experience. The soft plug can increase the stability of the earphones in the ear canal 220, preventing the earphones from slipping during wear and improving safety. The soft plug is generally removable, allowing the user to replace or clean it as needed, maintaining the hygiene of the earphones. Soft plugs of different sizes and hardness can be provided according to user needs to meet the personalized needs of different users.
