It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.

In some embodiments, as shown in connection with fig. 1, an audio sound system 1 is provided that includes a plurality of channel speakers. The plurality of sound channel speakers include a main sound channel speaker 10, a center speaker 20, a sky sound speaker 30, a surround speaker 40, and a subwoofer 50, which are arranged at intervals. The number of the heavy bass speakers 50 is two, and the two heavy bass speakers 50 are respectively located at two opposite sides of the center speaker 20.

The number of the subwoofers 50 of the sound system 1 provided in the embodiment of the disclosure is two, and the two subwoofers 50 are respectively located at two opposite sides of the center speaker 20 for performing distributed power output. By dividing the bass channel into two subwoofers 50 for distributed power output, a higher low-frequency sound pressure is achieved than in the related art. In addition, through the distributed power output of the dual bass loudspeaker 50, when the sound system 1 processes low-frequency signals, the original signals can be restored more accurately, extra harmonic components introduced by internal factors of the sound system 1 are reduced, total harmonic distortion of low tones is reduced, low-frequency sound effects are balanced better, purer and natural bass manifestations are provided, deep bass can be felt at each corner of a listening area, and immersion feeling of the sound system 1 and use experience of the sound system 1 of a user are improved.

Illustratively, referring to fig. 2, fig. 2 is a low-frequency audio response comparison diagram of an audio system according to an embodiment of the present disclosure and a conventional audio system. Wherein the horizontal axis represents sound frequency and the vertical axis represents sound pressure level (Sound Pressure Level, SPL). Curve a shows the frequency sound pressure curve of the bass channel of the sound system 1 according to the embodiment of the present disclosure. Curve b represents the frequency sound pressure curve of the bass channel of a conventional sound system. The sound system 1 according to the embodiment of the present disclosure is provided with two subwoofers 50, where the two subwoofers 50 are respectively located at two opposite sides of the center speaker 20, and perform distributed power output (taking the output power of the two subwoofers 50 as an example, all 25 w). The conventional sound system is provided with a single heavy bass speaker 50, and the output power of the heavy bass speaker 50 is 50w. As can be seen in conjunction with fig. 2, compared with the conventional sound system, the sound system 1 according to the embodiment of the disclosure has higher sound pressure and lower THD (Total Harmonic Distortion ) at low frequency, can effectively inhibit the formation of standing waves, brings purer bass, and realizes the bass effect of 1+1> 2.

Alternatively, as shown in connection with fig. 3, the subwoofer 50 includes a first cabinet 510, a bass unit 520, and two radiating cones 530. The bass unit 520 is disposed in the first housing 510. The two radiating cones 530 are disposed at intervals in the first case 510, and the two radiating cones 530 are respectively located at opposite sides of the bass unit 520.

In this embodiment, the subwoofer 50 includes one bass unit 520 and two radiating cones 530. Wherein, the bass unit 520 is an active sound generating unit of the subwoofer 50 for generating a bass signal and pushing air to vibrate, thereby generating a bass effect. The radiation tub 530 is an auxiliary sound generating unit, i.e., a passive unit, without an independent driving unit. The radiating tub 530 can vibrate along with the vibration of the bass unit 520, increasing the output and diffusion range of bass sounds, enhancing the bass sound effect, and making the entire bass sound zone more full and stereoscopic. In addition, through setting up two radiation basins 530 interval in first box 510, and be located the opposite both sides of bass unit 520 respectively for two radiation basins 530 can make full use of the sound wave of bass unit 520 radiation, realize higher sound sensitivity, make the low frequency of heavy bass audio amplifier 50 dive simultaneously, widen low frequency range, in order to embody more sound details, further strengthen the bass effect.

Optionally, the first case 510 includes a bass chamber in which an end of the bass unit 520 remote from the transmitting end is located, and an edge portion of the radiating tub 530 is located.

In this embodiment, the end of the bass unit 520 remote from the transmitting end is located in the bass chamber, the edge portion of the radiating tub 530 is located in the bass chamber, and the radiating tub 530 and the bass unit 520 are coupled through the air inside the bass chamber. The bass chamber is the space for conditioning low frequency sound waves. By placing the end of the bass unit 520 remote from the transmitting end in the bass chamber, it is ensured that the sound waves generated by the bass unit 520 during operation can be sufficiently diffused in the chamber. The edge portion of the radiating basin 530 is located in the bass chamber, so as to ensure that the radiating basin 530 can stably receive the sound waves emitted by the bass unit 520, and enhance and diffuse the sound waves through the special shape and structure of the radiating basin 530, so that the sound wave energy is uniformly distributed in the whole bass chamber, and the sound waves reflected and enhanced by the bass chamber are further diffused outside the heavy bass loudspeaker 50, thereby providing a broader and deep bass effect experience for users. In addition, the end of the bass unit 520 far from the transmitting end and the edge of the radiating basin 530 are positioned in the bass cavity, so that the propagation path and reflection mode of sound waves are controlled, the distortion and standing wave phenomenon of sound can be reduced, unnecessary sound wave interference is reduced, and the low-frequency sound effect is purer and clearer.

Alternatively, the volume of the bass chamber is 1.6 liters.

In this embodiment, the volume of the bass chamber is optimized. If the volume of the bass chamber is too small, it may not be possible to accommodate a sufficient volume of air to support the propagation of low frequency sound waves, resulting in poor low frequency effects. If the volume of the bass chamber is too large, the sound waves may be excessively diffused in the chamber, reducing the clarity and localization of the sound. In this embodiment, the volume of the bass chamber is optimized, the volume of the bass chamber is limited to 1.6 liters, the sound wave generated by the bass unit 520 can be fully reflected and diffused in the bass chamber, the low-frequency diving can reach 50Hz, and the intensity and texture of the bass sound effect are enhanced.

Alternatively, the bass unit 520 has a diameter of 3.5 inches.

The design size of the existing electronic equipment products is mostly developed in a thin or small direction, such as the wall-mounted television 2. In the embodiment of the present disclosure, the diameter size of the bass unit 520 is optimized, and the diameter of the bass unit 520 is defined to be 3.5 inches, so as to reduce the volume of the heavy bass loudspeaker 50, enable the heavy bass loudspeaker 50 to adapt to the development direction of the multimedia electronic device, and improve the applicability of the heavy bass loudspeaker 50.

Note that the woofer 520 also weighs the woofer. The subwoofer and the basin 530 are conventional and the present application will not be described in detail with respect to the subwoofer and basin 530.

Optionally, the output power of the subwoofer 50 is P ₁,0≤P₁ watts less than or equal to 25 watts.

The output power determines the volume level and the intensity of the low frequency response that the subwoofer 50 can produce. If the output power is too high, the problems of distortion or overheating of the subwoofer 50 can be caused, and the sound quality and the service life can be affected. In this embodiment, the output power of the subwoofer 50 is limited to ensure long-term stable operation and sound performance of the subwoofer 50.

The two first intermediate frequency units 220 are disposed in the second box 210 at intervals. The first high-frequency units 230 are disposed in the second box 210 and are spaced apart from the two first intermediate-frequency units 220.

The first if unit 220 is responsible for outputting the frequency band relatively middle in the audio, such as the human voice and the instrument voice. The first high frequency unit 230 is used for taking charge of output of high frequency parts in audio, such as details in music and high frequency components of sound. In this embodiment, the two first if units 220 are disposed in the second casing 210 at intervals, so that the center speaker 20 can more effectively cover a wider listening area, ensure uniform distribution of sound in the listening space, reduce phase cancellation or superposition of sound at a specific frequency, and make the sound of the if part clearer and more natural. The first high frequency unit 230 and the two first intermediate frequency units 220 are spaced apart to ensure balance between high frequency and intermediate frequency sounds, avoid mutual interference, and provide a clearer and finer sound experience for the user.

Alternatively, the first midrange unit 220 comprises a full frequency speaker having a diameter size of 2 inches.

Full-range speakers are capable of covering a wide range of audio frequencies, including mid-frequency portions. In this embodiment, the full-range speaker has a diameter size of 2 inches. The 2-inch full-band speaker is mainly adapted to the first intermediate frequency unit 220. A 2 inch full-range speaker main can provide clear, balanced sound performance at the mid-range frequency. In addition, the 2 inch size also allows the full range speaker to accommodate different installation and space requirements.

Alternatively, the first high frequency unit 230 includes a silk membrane dome speaker.

The silk membrane dome high pitch is one of dome high pitch, mainly adopts the technology of point sound source to sound, and can only send out high pitch part. When playing music, the high-pitched part of the silk membrane ball top is smart and loose, and has good natural expressive force. The first high-frequency unit 230 of the embodiment of the present disclosure adopts a silk film dome high-pitched sound to enhance the tone quality performance of the center speaker 20 in the high-frequency portion, so that the center speaker 20 can present a clearer, natural and pleasant high-pitched sound effect when playing music.

The full-frequency loudspeaker and the silk membrane dome speaker are the prior art, and the application is not described too much.

Optionally, output power P ₂＝2P₀₂/3 of center speaker 20, where P ₀₂ is the power rating of center speaker 20.

Rated power P ₀₂ refers to the maximum power that center speaker 20 can continuously output under normal operating conditions. In this embodiment, output power P ₂＝2P₀₂/3 of center speaker 20 is defined to ensure that center speaker 20 is operating at a sufficient volume without distortion or damage due to excessive power. By setting P ₂＝2P₀₂/3, the middle-set sound box 20 can provide sound volume output close to rated power under most conditions, and a certain power margin is reserved at the same time, so as to cope with sudden high sound volume demand or short-time overload conditions, ensure stability and reliability of the middle-set sound box 20 in normal operation, and provide high-quality audio experience for users.

Alternatively, as shown in connection with fig. 5, the main channel enclosure 10 includes a left channel enclosure 12 and a right channel enclosure 14. Left channel box 12 and right channel box 14 are located on the sides of the two subwoofers 50 away from center box 20, respectively.

In this embodiment, the main sound channel enclosure 10 is composed of a left sound channel enclosure 12 and a right sound channel enclosure 14, and the left sound channel enclosure 12 and the right sound channel enclosure 14 are respectively located at one side of the two subwoofer enclosures 50 away from the center sound enclosure 20, so as to ensure balanced distribution of sound and enhance stereo perception and layering of sound. The left channel box 12 is responsible for processing and playing the left channel portion of the music or sound signal and the right channel box 14 is responsible for playing the right channel portion. The split mode enables the sound to be more naturally and truly presented in space, particularly when the stereo effect is presented, a user can feel the flow and change of the sound from left to right, and the sense of reality and immersion of the listening experience are enhanced.

In addition, by disposing the left channel speaker 12 and the right channel speaker 14 on the side of the subwoofer 50 away from the center speaker 20, interference and overlapping of sound signals are avoided, ensuring that the sound between the individual speakers can be clearly distinguished. At the same time, the sound can be distributed more uniformly in space, and a wider and natural hearing feeling is brought to the user.

Further, the specific structure of the main channel speaker 10 is the same as that of the center speaker 20, and for the specific structure and technical effects of the main channel speaker 10, reference is made to the center speaker 20 described above, which is not described herein.

Alternatively, as shown in fig. 1 and 5, the number of sky-sound speakers 30 is two, and two sky-sound speakers 30 are disposed adjacently.

Through setting up two sky sound audio amplifier 30 adjacently, two sky sound audio amplifier 30 collaborative work, the sound effect at reinforcing listening space top to further ensure the evenly distributed and the continuity of sound in the space, avoid the fracture or the inconsistency of sound. Meanwhile, the adjacent arrangement of the two sky-sound boxes 30 can reduce attenuation and distortion of sound in the transmission process, so that the sound at the top of the listening space is clearer, brighter and plump.

Optionally, as shown in fig. 6, the sky sound box 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 disposed at intervals in the third case 310. The two second intermediate frequency units 340 are disposed in the third box 310 at intervals, and are distributed with the two second high frequency units 320 at intervals.

The second high frequency unit 320 is used for playing high frequency parts in audio, such as some crisp, bright sounds. The second if unit 340 is used for playing if parts in audio, such as some sounds rich in emotion and detail. In this embodiment, two second high frequency units 320 are disposed at intervals in the third case 310 to reduce interference and distortion of sound, so that the high frequency sound is clearer and more natural. The two second intermediate frequency units 340 are disposed in the third case 310 at intervals, and are spaced apart from the second high frequency units 320, so as to ensure balance and coordination between the intermediate frequency and the high frequency sounds, and avoid mutual interference. Through the coordinated operation of the two second high-frequency units 320 and the two second intermediate-frequency units 340, the sky-sound box 30 can present a clearer and wider audio effect, and particularly in the top and vertical space dimensions, a more immersive hearing experience is brought to the user. Simultaneously, the sound space with rich layers and strong third dimension is constructed together with other sound boxes.

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, which specifically requires a technician to select according to the actual product equipment.
