[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A, B, A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] In some embodiments, in combination Figure 1 As shown, a sound system 1 is provided, comprising a plurality of channel speakers. The plurality of channel speakers include a main channel speaker 10, a center speaker 20, a sky speaker 30, a surround speaker 40 and a subwoofer 50 which are arranged at intervals. There are two subwoofers 50, which are respectively located on opposite sides of the center speaker 20.

[0044] The number of subwoofers 50 of the sound system 1 provided in the embodiment of the present disclosure is two, and the two subwoofers 50 are respectively located on opposite sides of the center speaker 20 for distributed power output. Compared with one bass channel in the related art, by dividing the bass channel into two subwoofers 50 for distributed power output, a higher low-frequency sound pressure is achieved. In addition, through this distributed power output of the dual subwoofers 50, the sound system 1 can more accurately restore the original signal when processing the low-frequency signal, reduce the additional harmonic components introduced by the internal factors of the sound system 1, reduce the total harmonic distortion of the bass, better balance the low-frequency sound effect, provide a purer and more natural bass performance, ensure that every corner of the listening area can feel the deep bass, and enhance the immersion of the sound system 1 and the user's experience of using the sound system 1.

[0045] Exemplary, combined Figure 2 As shown, Figure 2This is a comparison chart of the bass response of the sound system described in an embodiment of the present disclosure and the traditional sound system. The horizontal axis represents the sound frequency, and the vertical axis represents the sound pressure level (SPL). Curve a represents the frequency sound pressure curve of the bass channel of the sound system 1 described in the embodiment of the present disclosure. Curve b represents the frequency sound pressure curve of the bass channel of the traditional sound system. The sound system 1 described in the embodiment of the present disclosure is provided with two subwoofers 50, and the two subwoofers 50 are respectively located on the opposite sides of the center speaker 20, and distributed power output is performed (taking the output power of the two subwoofers 50 as an example that both are 25w). The traditional sound system is equipped with a single subwoofer 50, and the output power of the subwoofer 50 is 50w. Combined with Figure 2 It can be seen that the audio system 1 described in the embodiment of the present disclosure has higher sound pressure and lower THD (Total Harmonic Distortion) at low frequencies compared to traditional audio systems, can effectively suppress the formation of standing waves, bring purer bass, and achieve a bass effect of 1+1>2.

[0046] Optionally, combined Figure 3 As shown, the subwoofer 50 includes a first box 510, a bass unit 520 and two radiation basins 530. The bass unit 520 is disposed in the first box 510. The two radiation basins 530 are disposed in the first box 510 at intervals, and the two radiation basins 530 are respectively located on opposite sides of the bass unit 520.

[0047] In this embodiment, the subwoofer 50 includes a woofer 520 and two radiation basins 530. The woofer 520 is an active sound-generating unit of the subwoofer 50, which is used to generate a bass signal and drive the air to vibrate, thereby producing a bass effect. The radiation basin 530 is an auxiliary sound-generating unit without an independent driving unit, that is, a passive unit. The radiation basin 530 can vibrate with the vibration of the woofer 520, increase the output and diffusion range of the bass, enhance the bass effect, and make the entire low-frequency sound segment fuller and more three-dimensional. In addition, by arranging the two radiation basins 530 at intervals in the first box 510 and respectively located on opposite sides of the woofer 520, the two radiation basins 530 can make full use of the sound waves radiated by the woofer 520 to achieve higher sound sensitivity, while allowing the low frequency of the subwoofer 50 to dive, widen the low-frequency range, so as to reflect more sound details and further enhance the bass effect.

[0048] Optionally, the first box 510 includes a bass cavity, an end of the bass unit 520 away from the transmitting end is located in the bass cavity, and an edge portion of the radiation basin 530 is located in the bass cavity.

[0049] In this embodiment, the end of the woofer 520 away from the transmitting end is located in the bass cavity, the edge of the radiation basin 530 is located in the bass cavity, and the radiation basin 530 and the woofer 520 are coupled through the air inside the bass cavity. The bass cavity is a space for adjusting low-frequency sound waves. By placing the end of the woofer 520 away from the transmitting end in the bass cavity, it is ensured that the sound waves generated by the woofer 520 when working can be fully diffused in the cavity. The edge of the radiation basin 530 is located in the bass cavity to ensure that the radiation basin 530 can stably receive the sound waves emitted by the woofer 520, and enhance and diffuse these sound waves through the special shape and structure of the radiation basin 530, so as to evenly distribute the sound wave energy to the entire bass cavity, and further diffuse the sound waves reflected and enhanced by the bass cavity to the outside of the subwoofer 50, bringing a wider and deeper low-frequency sound experience to the user. In addition, by placing the end of the woofer 520 away from the transmitting end and the edge of the radiation basin 530 in the bass cavity, the propagation path and reflection mode of the sound waves can be controlled, which can reduce sound distortion and standing waves, reduce unnecessary sound wave interference, and make the low-frequency sound effect purer and clearer.

[0050] Optionally, the volume of the bass chamber is 1.6 liters.

[0051] In this embodiment, the volume of the bass cavity is optimized. If the volume of the bass cavity is too small, it may not be able to accommodate sufficient air volume to support the propagation of low-frequency sound waves, resulting in poor low-frequency effects. If the volume of the bass cavity is too large, it may cause excessive diffusion of sound waves in the cavity, reducing the clarity and positioning of the sound. In this embodiment, the volume of the bass cavity is optimized, and the volume of the bass cavity is limited to 1.6 liters. The sound waves generated by the bass unit 520 can be fully reflected and diffused in the bass cavity, and the low-frequency dive can reach 50Hz, which enhances the intensity and texture of the low-frequency sound effects.

[0052] Optionally, the diameter of the woofer 520 is 3.5 inches.

[0053] The design dimensions of existing electronic equipment products are mostly developed in the direction of being thin or small, such as a wall-mounted TV 2. In the disclosed embodiment, the diameter of the bass unit 520 is optimized, and the diameter of the bass unit 520 is limited to 3.5 inches to reduce the volume of the subwoofer 50, so that the subwoofer 50 can adapt to the development direction of multimedia electronic equipment and improve the applicability of the subwoofer 50.

[0054] It should be noted that the bass unit 520 is also called a subwoofer. The subwoofer and the radiation basin 530 are both prior art, and this application will not introduce the subwoofer and the radiation basin 530 in detail.

[0055] Optionally, the output power of the subwoofer 50 is P1, 0≤P1≤25 watts.

[0056] The output power determines the volume and low-frequency response strength of the subwoofer 50. If the output power is too high, the subwoofer 50 may suffer from distortion or overheating, affecting the sound quality and service life. In this embodiment, the output power of the subwoofer 50 is limited to ensure the long-term stable operation and sound quality of the subwoofer 50.

[0057] Optionally, combined Figure 4 As shown, the center speaker 20 includes a second box 210, two first intermediate frequency units 220 and a first high frequency unit 230. The two first intermediate frequency units 220 are arranged in the second box 210 at intervals. The first high frequency unit 230 is arranged in the second box 210 and is spaced apart from the two first intermediate frequency units 220.

[0058] The first intermediate frequency unit 220 is responsible for the output of the relatively middle frequency band in the audio, such as human voice and musical instrument sound. The first high frequency unit 230 is responsible for the output of the high frequency part of the audio, such as the details in the music and the high frequency components of the sound. In this embodiment, the two first intermediate frequency units 220 are arranged at intervals in the second box 210, so that the center speaker 20 can more effectively cover a wider listening area, and ensure the uniform distribution of sound in the listening space, reduce the phase cancellation or superposition of the sound at a specific frequency, and make the sound of the intermediate frequency part clearer and more natural. The first high frequency unit 230 is spaced apart from the two first intermediate frequency units 220 to ensure the balance between the high frequency and intermediate frequency sounds, avoid mutual interference, and provide users with a clearer and more delicate sound experience.

[0059] Optionally, the first intermediate frequency unit 220 includes a full-range speaker, and the diameter of the full-range speaker is 2 inches.

[0060] The full-range speaker can cover a wide audio frequency range, including the mid-frequency part. In this embodiment, the diameter of the full-range speaker is 2 inches. The 2-inch full-range speaker is mainly suitable for the first mid-frequency unit 220. The 2-inch full-range speaker can mainly provide clear and balanced sound performance in the mid-frequency band. In addition, the 2-inch size also enables the full-range speaker to adapt to different installation and space requirements.

[0061] Optionally, the first high frequency unit 230 includes a silk dome tweeter.

[0062] The silk dome tweeter is a type of dome tweeter, which mainly uses the point sound source technology to produce sound and can only produce the treble part. When the silk dome tweeter plays music, the treble part is flexible and relaxed, and has good natural expressiveness. The first high-frequency unit 230 of the disclosed embodiment adopts a silk dome tweeter to improve the sound quality performance of the center speaker 20 in the high-frequency part, so that the center speaker 20 can present a clearer, natural and pleasant treble effect when playing music.

[0063] It should be noted that full-range speakers and silk dome tweeters are existing technologies, and this application will not provide detailed introductions to the full-range speakers and silk dome tweeters.

[0064] Optionally, the output power of the center speaker 20 is P2=2P 02 / 3, where P 02 is the rated power of the center speaker 20.

[0065] Rated power P 02 Refers to the maximum power that the center speaker 20 can continuously output under normal working conditions. In this embodiment, the output power of the center speaker 20 is limited to P2 = 2P 02 / 3, to ensure that the center speaker 20 can provide sufficient volume when working, but will not be distorted or damaged due to excessive power. By setting P2 = 2P 02 / 3, so that the center speaker 20 can provide a volume output close to the rated power in most cases, while retaining a certain power margin to cope with sudden high volume demands or short-term overload conditions, ensuring the stability and reliability of the center speaker 20 during normal operation, while providing users with a high-quality audio experience.

[0066] Optionally, combined Figure 5 As shown, the main channel speaker 10 includes a left channel speaker 12 and a right channel speaker 14. The left channel speaker 12 and the right channel speaker 14 are respectively located at one side of the two subwoofer speakers 50 away from the center speaker 20.

[0067] In this embodiment, the main channel speaker 10 is composed of a left channel speaker 12 and a right channel speaker 14, and the left channel speaker 12 and the right channel speaker 14 are respectively located on the side of the two subwoofers 50 away from the center speaker 20, so as to ensure the balanced distribution of the sound and enhance the stereoscopic and layered sense of the sound. The left channel speaker 12 is responsible for processing and playing the left channel part of the music or sound signal, and the right channel speaker 14 is responsible for playing the right channel part. This division of labor makes the sound more natural and realistic in space, especially when showing the stereo effect, so that the user can feel the flow and change of the sound from left to right, enhancing the realism and immersion of the listening experience.

[0068] In addition, by placing the left channel speaker 12 and the right channel speaker 14 on the side of the subwoofer 50 away from the center speaker 20, mutual interference and overlap of sound signals are avoided, ensuring that the sounds of each speaker can be clearly distinguished. At the same time, the sound can be more evenly distributed in the space, bringing a wider and more natural listening experience to the user.

[0069] Furthermore, the specific structure of the main channel speaker 10 is the same as that of the center speaker 20. The specific structure and technical effects of the main channel speaker 10 may refer to the above-mentioned center speaker 20, which will not be described in detail here.

[0070] Optionally, combined Figure 1 and Figure 5 As shown, there are two sky sound boxes 30, and the two sky sound boxes 30 are arranged adjacent to each other.

[0071] In this embodiment, the sky sound speaker 30 is used to reflect the sound above the user, simulating a more realistic and natural listening environment. By placing two sky sound speakers 30 adjacent to each other, the two sky sound speakers 30 work together to enhance the sound effect at the top of the listening space, further ensuring the uniform distribution and continuity of the sound in the space, and avoiding the breakage or inconsistency of the sound. At the same time, the adjacent arrangement of the two sky sound speakers 30 can reduce the attenuation and distortion of the sound during the propagation process, making the sound at the top of the listening space clearer, brighter and fuller.

[0072] Optionally, combined Figure 6 As shown, the sky sound speaker 30 includes a third box 310, two second high frequency units 320 and two second intermediate frequency units 340. The two second high frequency units 320 are arranged at intervals in the third box 310. The two second intermediate frequency units 340 are arranged at intervals in the third box 310 and are spaced apart from the two second high frequency units 320.

[0073] The second high frequency unit 320 is used to play the high frequency part of the audio, such as some crisp and bright sounds. The second intermediate frequency unit 340 is used to play the intermediate frequency part of the audio, such as some emotional and detailed sounds. In this embodiment, the two second high frequency units 320 are arranged at intervals in the third box 310 to reduce the interference and distortion of the sound and make the high frequency sound clearer and more natural. The two second intermediate frequency units 340 are arranged at intervals in the third box 310 and are distributed at intervals with the second high frequency unit 320 to ensure the balance and coordination between the intermediate frequency and high frequency sounds and avoid mutual interference. Through the coordinated work of the two second high frequency units 320 and the two second intermediate frequency units 340, the sky sound speaker 30 can present a clearer and wider audio effect, especially in the top and vertical space dimensions, bringing a more immersive listening experience to the user. At the same time, it works in coordination with other speakers to jointly build a sound space with rich layers and strong three-dimensional sense.

[0074] It should be noted that in the present application, the first intermediate frequency unit 220 and the second intermediate frequency unit 340, the first high frequency unit 230 and the second high frequency unit 320 may be the same or different, and the specific selection needs to be made by technical personnel according to actual product equipment.

[0075] Optionally, combined Figure 5 As shown, the surround sound box 40 includes a left surround sound box 42 and a right surround sound box 44. The left surround sound box 42 and the right surround sound box 44 are arranged opposite to each other and are both adjacent to the sky sound box 30 and the main channel sound box 10.

[0076] The left surround speaker 42 is used to produce surround sound effects on the left and rear of the user, while the right surround speaker 44 is used to produce surround sound effects on the right and rear of the user. In this embodiment, the left surround speaker 42 and the right surround speaker 44 are arranged relative to each other to create a more balanced and natural surround sound field. In addition, the left surround speaker 42 and the right surround speaker 44 are adjacent to the sky sound speaker 30 and the main channel speaker 10 to ensure that the sounds between the speakers can be integrated with each other to form a seamless audio experience. The adjacent arrangement of the surround speaker 40 and the sky sound speaker 30 allows the surround sound effect to be extended in the vertical direction, enhancing the spatial sense of the sound. The adjacent arrangement of the surround speaker 40 and the main channel speaker 10 ensures a smooth transition between the main sound and the surround sound effect, avoiding breaks or abruptness between the sounds. Through the collaboration between multiple speakers, users can feel sounds from different directions, making users feel as if they are in a three-dimensional space full of sound, creating a more realistic and immersive listening environment, and enhancing the sense of immersion.

[0077] Furthermore, the specific structure of the surround sound box 40 is the same as that of the sky sound box 30. The specific structure and technical effects of the surround sound box 40 may refer to the above-mentioned sky sound box 30, which will not be repeated here.

[0078] Optionally, combined Figure 1 and Figure 5 As shown, along the height direction of the audio system 1, the setting height of the sky sound speaker 30 is higher than the surround speaker 40, the setting height of the surround speaker 40 is higher than the main channel speaker 10, and the setting heights of the main channel speaker 10, the center speaker 20 and the subwoofer 50 are the same.

[0079] In this embodiment, the arrangement position of each speaker is optimized to improve the sound quality and listening experience, enhance the sense of immersion and stereoscopic feeling, and bring a better listening experience to the user. Specifically, the setting height of the sky sound speaker 30 is higher than the surround speakers 40, so as to project the sound to the top of the listening space and enhance the vertical dimension and stereoscopic feeling of the sound. The high-position setting of the sky sound speaker 30 can simulate a wider and deeper sound field, allowing users to experience a more real and immersive listening experience.
