Technical Field

[0001] This utility model relates to the field of audio playback device technology, specifically to a multi-channel headset. Background Technology

[0002] Audio formats include 2-channel, 2.1-channel, 3.1-channel, 5.1-channel, and 7.1-channel, widely used for distribution and listening enjoyment in fields such as music, film, and games. To accommodate these audio formats, a multi-speaker structure is required for separate output. The multi-channel design makes sound positioning more accurate and the sound layering more distinct. When listening to music, especially complex musical works such as symphonies, the sounds of different instruments are played in different channels, creating an immersive experience.

[0003] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Gaming headsets, also known as esports headsets, are a type of headset specifically designed for optimized audio effects in video games, primarily used to enhance players' ability to pinpoint sound locations in competitive games. Compared to traditional headphones, which focus on high-fidelity sound quality, gaming headsets help players identify details such as footsteps and weapon positions by enhancing soundstage positioning, low-frequency rendering, and directional resolution technologies.

[0004] The existing single-speaker unit cavity design cannot reproduce the full-range signal well with a single speaker unit. In contrast, the dual-speaker or multi-speaker unit cavity design, where all speaker units are in one cavity, will interfere with each other and cause severe distortion when the speaker units are working.

[0022] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0023] Please see Figures 1 to 5 This document illustrates a multi-channel headphone 100, comprising a headband 10 and two headphone bodies 20 respectively disposed at both ends of the headband 10. Each headphone body 20 includes an earphone shell 21, a speaker bracket 23, a cavity bracket 24, and a speaker assembly. The speaker bracket 23, the cavity bracket 24, and the speaker assembly are installed inside the earphone shell 21. The speaker assembly includes a front speaker 31, a rear speaker 32, a center speaker 33, a side speaker 34, and a woofer 35.

The cavity bracket 24 covers the outside of the speaker bracket 23, so that the front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34 each correspond to an independent cavity 241, eliminating acoustic interference between the speakers and making the emitted sound purer.

[0024] Specifically, through the interaction between the sound card and the multi-channel headphones 100, a stereo sound field can be created in space. In this embodiment, the multi-channel headphones 100 implements a 7.1 surround sound configuration, satisfying the surround settings of 7 sound zones (left front surround, right front surround, center surround, left rear surround, right rear surround, left surround, and right surround) and subwoofer, achieving a good sense of spatial positioning, so as to capture the movement of enemies in games or experience a sense of presence in movies, allowing users to experience more realistic sound effects when watching movies or playing games.

[0025] Preferably, such as Figure 5 As shown, the speaker bracket 23 includes a bracket plate 231, which has a front and a back corresponding to the front. The back of the bracket plate 231 is provided with four regularly arranged speaker mounting parts 232. Each speaker mounting part 232 has a side wall of a predetermined height. The front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34 are respectively installed in each of the speaker mounting parts 232.

[0026] Preferably, the four speaker mounting portions 232 are spaced apart by a predetermined distance, and the four speaker mounting portions 232 are arranged around the central part of the support plate 231. The central part of the support plate 231 and the corresponding positions of the four speaker mounting portions 232 are provided with a plurality of sound holes 2311.

[0027] Specifically, the four speaker mounting parts 232 are arranged in a cross shape, with the four speaker mounting parts 232 respectively positioned above, below, to the left and to the right of the central part of the support plate 231; the central part of the support plate 231 and the positions corresponding to the four speaker mounting parts 232 are each provided with a plurality of regularly arranged sound holes 2311.

[0028] Specifically, in this embodiment, the four speakers are installed as follows: after the headphones are worn on the head, with the ear as the center, the woofer 35 is located in the center of the support plate 231, the front speaker 31 is located in front of the woofer 35, the center speaker 33 is located behind the woofer 35, the side speaker 34 is located above the woofer 35, and the rear speaker 32 is located below the woofer 35. The left and right headphone bodies 20 are symmetrically arranged.

[0029] Preferably, such as Figure 4 As shown, the cavity support 24 includes four independent cavities 241, the openings of the four independent cavities 241 face the same direction, and the positions of the four independent cavities 241 correspond to the positions of the four speaker mounting parts 232. Each independent cavity 241 has a sidewall of a predetermined height.

[0030] Preferably, the cavity support 24 further includes a bass speaker mounting part 242, which is located in the center of the four speaker mounting parts 232. Both ends of the bass speaker mounting part 242 have openings, and the bass speaker 35 is mounted in the bass speaker mounting part 242.

[0031] Preferably, the bottom of the independent cavity 241 has a first tuning hole 2411, which is elliptical. Figure 3 As shown, the earphone shell 21 has a plurality of regularly arranged second tuning holes 211 on its edge sidewall, and the second tuning holes 211 are circular. Both the first tuning hole 2411 and the second tuning hole 211 are covered with tuning mesh.

[0032] Specifically, the tuning port, also known as a pressure relief port, connects the cavity behind the speaker unit to the external environment, controlling airflow to balance air pressure and optimize acoustic performance. The tuning port operates based on the Helmholtz resonance principle, and its main functions include: 1. Phase Adjustment: By allowing the rearward sound waves of the bass driver unit to radiate out from the tuning port, the phase matching between the bass and treble units is adjusted, making the sound wave synthesis effect more natural.

[0033] 2. Low-frequency enhancement: The low-frequency sound waves that interfere with each other inside the cabinet are radiated out through the tuning port, and the low-frequency performance is enhanced by superimposing them with the original sound.

[0034] 3. Airflow optimization: Adjust the airflow inside and outside the chamber to reduce unnecessary resonance and distortion.

[0035] Specifically, in this embodiment, the first tuning hole 2411 is an elliptical tuning hole, which can balance sound diffusion and frequency band balance; the second tuning hole 211 is a circular tuning hole, which can provide a smoother frequency response curve, especially with more natural attenuation in the high-frequency part. The sound field produced by the circular and elliptical tuning holes is wider, which is suitable for creating a surround sound effect.

[0036] Specifically, the mesh count of the tuning mesh directly affects the perceived sound. A higher mesh count results in a denser mesh, greater acoustic impedance, and a more pronounced attenuation effect on sound, especially in the mid-to-high frequencies. Conversely, a lower mesh count results in a sparser mesh, less acoustic impedance, and a smaller impact on sound clarity. Therefore, the mesh count of the tuning mesh covering the first tuning hole 2411 and the second tuning hole 211 is different.

[0037] In this embodiment, a tuning mesh with a small mesh count is selected, which has a high air permeability and low acoustic impedance, thereby improving the clarity and transparency of the sound and making the sound clearer and more natural.

[0038] Preferably, the earphone shell 21 is hemispherical or semi-elliptical, and the earphone shell 21 covers the outside of the cavity support 24, so that the earphone shell 21 becomes the rear cavity of the bass speaker 35; The subwoofer 35 is installed outside the installation positions of the front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34, so that the sound emitted by the subwoofer 35 passes through the front cavity formed by the central part of the four speaker mounting parts 232.

[0039] Specifically, when the headphones 100 are worn on the head, the side closer to the ear is considered the inner side, and the side further away from the ear is considered the outer side. In this technical solution, the front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34 are located on the inner side, and the subwoofer 35 is located on the outer side.

[0040] Specifically, the subwoofer 35, the front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34 form a double-layer installation, making the installation structure of each speaker in the speaker group compact and effectively reducing the overall size of the headphone 100.

[0041] In this embodiment, the woofer 35 is positioned in the center of the front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34, so that the woofer 35 has a front cavity and a rear cavity, forming a complete acoustic system.

[0042] The layered design of the cavity support 24 and the speaker support 23 ensures that each speaker in the speaker assembly has its own independent and sealed cavity, while saving space inside the headphone shell 21. The cavity support 24 forms the speaker cabinet frame, and the woofer 35 is mounted on the frame. When the woofer 35 is working, the sound is guided by the front and rear cavities, resulting in a richer and more powerful low-frequency sound with better sound effects.

[0043] Preferably, an absorbent cotton pad is provided between the cavity support 24 and the speaker support 23. The shape of the sound-absorbing cotton pad 25 is the same as the shape of the contact surface between the cavity support 24 and the speaker support 23. The sound-absorbing cotton pad 25 is used to seal and isolate each of the independent cavities 241 to prevent the independent cavities 241 from being interfered with by external sounds.

[0044] Preferably, the headphone body 20 further includes an earcup 22, the earcup 22 including a substrate 221 and an ear pad 222, the headphone shell 21 is fastened to the side of the substrate 221 to form a closed space, the speaker bracket 23, the cavity bracket 24 and the speaker assembly are disposed in the closed space; the ear pad 222 is used to contact human skin, so that the earcup 22 covers the human ear.

[0045] Preferably, the support plate 231 of the speaker bracket 23 is attached to the substrate 221, and the cavity bracket 24 is covered by the sound-absorbing cotton pad 225, so that the independent cavity 241 and the speaker mounting part 232 are correspondingly arranged to form a sealed independent space; the top of the side wall of the earphone shell 21 has a claw, which cooperates with the buckle on the edge of the ear cup 22, so that the earphone shell 21 is fastened to the ear cup 22.

[0046] Specifically, in this embodiment, the headphone body 20 is formed by sequentially installing the earcups 22, the speaker bracket 23, the sound-absorbing cotton pad 25, the cavity bracket 24, and the headphone shell 21 from the inside out. The front speaker 31, the rear speaker 32, the center speaker 33, and the side speaker 34 are respectively installed in the speaker mounting portions 232 of the speaker bracket 23, and the bass speaker 35 is installed in the bass speaker mounting portion 242 of the cavity bracket 24.

[0047] Specifically, the headset 100 also includes a microphone 40, which is located below the left side of the headset body 20 and is used for calls and voice input.

[0048] In the aforementioned multi-channel headphones 100, each headphone body 20 is equipped with five speakers: a front speaker 31, a rear speaker 32, a center speaker 33, a side speaker 34, and a subwoofer 35. Each speaker has its own independent cavity 241 to avoid acoustic interference between the speakers, resulting in a purer sound. The speakers in the speaker group are arranged in two layers, with the subwoofer 35 positioned higher than the front, rear, center, and side speakers 34. The subwoofer 35 is located in the center of these three speakers, optimizing low-frequency sound and making the overall structure of the headphones 100 more compact. This invention features a simple structure, is easy to implement, has low cost, and is readily available for widespread adoption.
