[0049] The following is for reference. Figures 1-7 The description of the voice-controlled noise-canceling headphones 10 according to an embodiment of the present invention includes: a main control box 100, in which a controller (not shown in the figure) is disposed; an earbud 200, in which an earbud cover 210 is disposed at the ear inlet end (not shown in the figure), the earbud cover 210 having a shark fin structure, a speaker 220 disposed inside the earbud 200, and a feedforward microphone 230 and a feedback microphone 240 respectively disposed on both sides of the speaker 220; a cable 300, the opposite ends of the cable 300 being connected to the main control box 100 and the earbud 200 respectively; and a voice noise reduction module 400, which is disposed in the main control box 100 and electrically connected to the controller, the voice noise reduction module 400 including a noise reduction chip 410, the noise reduction chip 410 being electrically connected to the speaker 220, the feedforward microphone 230 and the feedback microphone 240 respectively.

[0050] Specifically, the main control box 100 can be constructed as a rectangular box structure, and the interior of the main control box 100 can have a receiving cavity 110. The main control box 100 can be constructed of aluminum-magnesium alloy, which has advantages such as lightweight and high strength, thereby significantly improving the service life of the main control box 100. The PCB board 120 can be fixedly installed in the receiving cavity 110 of the main control box 100 by means of threaded connection. The controller can be fixedly installed on the PCB board 120 by means of threaded connection and soldering. This configuration can improve the stability of the controller.

[0051] The number of earbuds 200 can be two. Each earbud 200 has an ear tip 210 attached to its in-ear end. The ear tip 210 is movably connected to the earbud 200 via a snap-fit ​​connection. This design allows for quick installation and removal of the ear tip 210, enabling users to easily replace or clean it as needed, thus extending the lifespan of the earbuds 200. Multiple ear tips 210 can be provided, and in multiple sizes, such as S, M, and L, to fit different ear shapes, achieving optimal noise cancellation and improving user comfort.

[0052] The ear tip 210 can be constructed in a shark fin shape, and the construction material of the ear tip 210 can be a composite silicone rubber material. The circular umbrella-shaped part at the front end of the ear tip 210 can extend into the user's ear canal and fit snugly. The shark fin structure ear tip 210 is designed with the optimal auditory characteristic curve of the human ear, so that the receiving frequency response of the voice-controlled noise-canceling headphones 10 is more in line with the auditory characteristics of the human ear, thereby achieving a good subjective listening effect. With this design, the voice-controlled noise-canceling headphones 10 can achieve a noise reduction of up to 35dB in the mid-to-high frequency band, covering a frequency range of 3kHz-8kHz.

[0053] The speaker 220 can be glued to the inside of the earbud 200. The feedforward microphone 230 and the feedback microphone 240 are respectively positioned on opposite sides of the speaker 220 via a slot-locking connection. It is important to note that the feedforward microphone 230 should be installed inside the earbud 200, away from the earbud cover 210. The feedforward microphone 230 can directionally collect external ambient noise (e.g., traffic, human voices). The feedback microphone 240 is attached to the inside of the speaker 220, allowing real-time monitoring of residual noise in the ear canal (e.g., sound leakage, resonance). Sound is played back to the ear canal through the speaker 220, and the sound is superimposed and canceled out by the noise in the ear canal, thus achieving active noise reduction.

[0054] One end of the cable 300 can be electrically connected to the controller inside the main control box 100, and the other end of the cable 300 can be electrically connected to the speaker 220, feedforward microphone 230 and feedback microphone 240 inside the earphone 200. With this configuration, the working status of the speaker 220, feedforward microphone 230 and feedback microphone 240 can be directly controlled by the controller.

[0055] The voice noise reduction module 400 can be integrated into the PCB board 120 inside the main control box 100 by soldering. The voice noise reduction module 400 can be electrically connected to the controller. This setting can reduce the number of external connection cables 300 and optimize the space utilization inside the main control box 100.

[0056] The voice noise reduction module 400 may include a noise reduction chip 410, which can be electrically connected to the speaker 220, the feedforward microphone 230, and the feedback microphone 240, respectively. With this configuration, the noise reduction chip 410 can measure the noise signal collected by the feedforward microphone 230 and the acoustic parameters inside the earpiece 200 cavity, generating a secondary sound wave with the same frequency, amplitude, and opposite phase as the original noise sound wave (i.e., the primary sound wave). The secondary sound wave can be played back into the earpiece 200 cavity through the speaker, canceling out the primary sound wave and thus reducing noise. The noise reduction chip 410 can work in conjunction with the speaker 220, the feedforward microphone 230, and the feedback microphone 240 to jointly realize the active noise reduction function of the voice-controlled noise-canceling headphones 10.

[0057] According to the embodiment of this utility model, the voice-controlled noise-canceling headphones 10 can provide stable support for the controller by setting the main control box 100; the earplugs 200 can adapt to the ear shape of different users, thereby achieving the best noise reduction effect and improving the user's wearing comfort. The shark fin structure earplug 210 is designed with the best hearing characteristic curve of the human ear, so that the receiving frequency response of the voice-controlled noise-canceling headphones 10 is more in line with the hearing characteristics of the human ear, thereby achieving a good subjective hearing effect; the feedforward microphone 230 can directionally collect external environmental noise. The feedback microphone 240 can monitor residual noise in the ear canal in real time, and the sound played back by the speaker 220 can be superimposed and canceled out by the noise in the ear canal, thereby achieving active noise reduction. By setting the cable 300, the controller can directly control the working status of the speaker 220, the feedforward microphone 230 and the feedback microphone 240. By setting the voice noise reduction module 400, it can work together with the speaker 220, the feedforward microphone 230 and the feedback microphone 240 to achieve active noise reduction of the voice-controlled noise-canceling headphones 10.

[0058] Please continue to participate. Figure 2 and Figure 3As shown, the voice-controlled noise-canceling headphones 10 also include: a limiting slot 500, which is disposed on the inner side of the earbud 200; and a limiting groove 600, which is disposed at one end of the earbud cover 210. The limiting groove 600 and the limiting slot 500 are engaged by a snap fastener to achieve a detachable connection between the earbud cover 210 and the earbud 200.

[0059] Specifically, the limiting slot 500 can be located on the inner side of the earbud 200 near the ear canal end, and the limiting slot 500 can be constructed as an irregular trapezoidal structure with an opening. The limiting slot 500 can be obliquely located on the inner side of the earbud 200, and the limiting slot 500 is integrally formed with the earbud 200 by injection molding. This design can reduce the manufacturing cost of the earbud 200.

[0060] The limiting groove 600 can be formed inside the earbud cover 210, and the limiting groove 600 can be constructed as an irregular groove with a boss 610. It should be noted that the shape of the limiting groove 600 should match the limiting slot 500, and the position structure of the boss 610 of the limiting groove 600 should match the opening of the limiting slot 500 of the earbud 200. This setting facilitates the locking of the limiting groove 600 and the limiting slot 500, thereby enabling the detachable connection between the earbud cover 210 and the earbud 200.

[0061] Please continue reading Figure 1 and Figure 7 As shown, according to one embodiment of the present invention, the voice-controlled noise-canceling headset 10 further includes a microphone 700, which is electrically connected to the controller via a cable 300.

[0062] Specifically, the microphone 700 can be configured as a microphone. The microphone 700 can be electrically connected to the controller inside the main control box 100 via cable 300. This configuration enables real-time voice interaction with the user and simultaneously improves the stability of voice signal transmission. The user can transmit voice signals to the microphone 700, which can convert the user's voice signals into electrical signals and transmit them to the controller.

[0063] Please continue reading Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the earplug 200 includes a sound-transmitting hole 250, which is disposed through the outer surface of the earplug 200 and coaxially aligned with the pickup port of the feedforward microphone 230.

[0064] Specifically, the sound-permeable hole 250 can be formed on the surface of the earbud 200 near the feedforward microphone 230. It is important to note that the sound-permeable hole 250 should be coaxially aligned with the pickup port of the feedforward microphone 230. With this configuration, the feedforward microphone 230 can collect ambient noise through the sound-permeable hole 250 and transmit it to the voice noise reduction module 400, which then processes the external noise. The sound-permeable hole 250 can also balance the air pressure inside and outside the earbud 200. When a user wears the voice-controlled noise-canceling headphones 10, because the earbud cover 210 fits tightly against the user's ear, the inside of the earbud 200 may be in a sealed environment. In this case, the air pressure inside the earbud 200 may be higher than the external pressure, which could potentially damage the electronic components inside the earbud 200 and affect the user's wearing experience. By setting the sound-permeable hole 250, air can circulate inside the earbud 200, thereby maintaining the air pressure balance between the inside and outside of the earbud 200, which can protect the electronic components inside the earbud 200 from damage and improve the user's wearing experience.

[0065] Please continue reading Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the earplug 200 further includes: a decorative cover 260, which is movably disposed on the surface of the earplug 200 and is disposed opposite to the sound transmission hole 250; and a tuning hole 270, which is radially distributed on the surface of the decorative cover 260.

[0066] Specifically, the decorative cover 260 can be movably installed on the surface of the earbud 200 via a snap-fit ​​mechanism. It is important to note that the decorative cover 260 should be positioned opposite the sound-transmitting hole 250. The decorative cover 260 can be available in various patterns and colors, allowing for a more personalized and stylish appearance of the earbud 200 to meet the aesthetic needs of different users. The decorative cover 260 can also conceal the complex internal electronic components and circuitry of the earbud 200, resulting in a cleaner and neater appearance and enhancing the overall aesthetics of the voice-controlled noise-canceling headphones 10. Furthermore, the decorative cover 260 provides a degree of physical protection for the internal electronic components of the earbud 200, effectively reducing damage from external impacts and significantly extending the lifespan of the voice-controlled noise-canceling headphones 10.

[0067] Multiple tuning holes 270 can be provided, and they can be radially distributed on the surface of the decorative cover 260. It is important to note that the tuning holes 270 should be positioned opposite to the sound-transmitting holes 250, and the diameter of the tuning holes 270 should be smaller than that of the sound-transmitting holes 250. This arrangement prevents dust and debris from entering the earbud 200, thus ensuring the safety of the internal electronic components. The tuning holes 270 also optimize the acoustic performance of the headphones, making the sound clearer and more natural, thereby enhancing the user's listening experience.

[0068] Please continue reading Figure 1 As shown, according to an optional embodiment of the present invention, the cable 300 is constructed as a helical spring structure.

[0069] Specifically, the cable 300 can be constructed as a spiral spring cable 300. The elasticity of the spring cable 300 allows it to be easily retracted, making it easy for users to operate during use. It also avoids the problem of traditional cables 300 easily tangling, making it convenient for users to store in pockets, bags, or hang on backpacks, thus improving the portability of the voice-controlled noise-canceling headphones 10. The spring cable 300 also effectively reduces wear and tear caused by pulling during use, thereby extending the lifespan of the voice-controlled noise-canceling headphones 10.

[0070] Please continue reading Figure 4 and Figure 5 As shown, according to a further embodiment of the present invention, the main control box 100 further includes a power supply assembly 130, which includes a battery 131 and a charging interface 132, the charging interface 132 being embedded in the bottom of the main control box 100.

[0071] Specifically, the battery 131 can be movably installed inside the main control box 100 via a snap-fit ​​mechanism, allowing for convenient removal and replacement. The battery 131 provides stable power to the controller and the electronic components inside the earphone 200. Along the height direction of the main control box 100, the charging interface 132 can be embedded in the bottom of the main control box 100. Figure 1 The direction indicated by X in the middle. The charging interface 132 can be configured as a standard Type-C charging interface 132. The Type-C interface has become a common standard in the consumer electronics field. With this setting, users do not need to carry a dedicated charging cable, thereby improving the practicality and versatility of the voice-controlled noise-canceling headphones 10.
