Particularly in long-distance sound reinforcement, many audio designers have devoted considerable effort to inventing and designing different cabinet structures to achieve the professional requirements for long-distance bass transmission. However, existing audio systems still suffer from technical problems related to poor low-frequency sound reproduction. Utility Model Content
[0003] The purpose of this invention is to provide an audio system and a car that solves the technical problem of poor low-frequency sound output in existing audio systems.
[0004] To achieve the above objectives, this utility model provides an audio speaker, which includes:
[0005] The enclosure includes two first side walls arranged parallel to each other and spaced apart along a first direction, and two second side walls arranged parallel to each other and spaced apart along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0033] The following description, with reference to the accompanying drawings, describes an audio system and a car according to the present invention.
[0034] like Figure 1As shown, in this embodiment, a speaker is proposed, comprising a cabinet 1, a speaker assembly, and two passive radiators 3. The cabinet 1 includes two first side walls arranged parallel to each other along a first direction and two second side walls arranged parallel to each other in the second direction, with the first and second directions perpendicular to each other. The two passive radiators 3 are symmetrically mounted on the two second side walls. The speaker assembly includes two woofers 21, which are symmetrically mounted on the two first side walls. The amplification ends of the two woofers 21 are opposite to each other and have different vibration frequencies. The technical solution in this embodiment achieves dual-core vibration damping by setting two opposite woofers 21, reducing noise. Furthermore, the vibration frequencies of the two woofers 21 are set to different values, enabling bass audio coupling between the two woofers 21, which improves the sound quality and effectively enhances the bass response of the speaker.
[0035] It should be noted that the first direction is... Figure 1 The front and back directions, the second direction is... Figure 1 The left and right directions. The amplifying end of the woofer 21 refers to the end of the woofer 21 where the paper cone is located. Figure 1 As can be seen, the paper cone is located at the front of the woofer 21. Dual-core vibration damping specifically means that the two woofers 21 have the same individual performance parameters and are symmetrically placed. Therefore, within a certain frequency range, the vibration generated by one woofer 21 can be partially canceled by the other woofer 21, thereby reducing the resonance of the enclosure 1 and making the sound of the speaker purer and clearer.
[0036] like Figure 1 As shown, the speaker assembly also includes two mid-range speakers 22, which can play mid- and high-frequency audio. Both mid-range speakers 22 are arranged on the same first side wall and are symmetrically arranged horizontally on both sides of the woofer 21, resulting in uniform sound vibration. In this embodiment, the mid-range speakers 22 are used to supplement the missing mid-to-high frequency range of the speaker, ensuring a smooth transition between the mid-to-high frequency range and the low-frequency range. This allows the speaker to play high frequencies in small spaces and low frequencies in large spaces, making it suitable for various operating conditions.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, a sound amplification cavity is formed inside the enclosure 1, and a storage part 11 for accommodating the midrange speaker 22 is also provided on the enclosure 1. The storage part 11 is located inside the sound amplification cavity, and there are multiple storage parts 11, which are arranged one-to-one with the midrange speaker 22. A storage slot 12 for accommodating the woofer 21 is formed on the first side wall, and the opening of the storage part 11 is connected to the storage slot 12.
[0038] Since this embodiment includes two midrange speakers 22, two storage compartments 11 are also provided. Each storage compartment 11 has a storage cavity, with the midrange speakers 22 partially placed within the cavity and their front ends positioned in the storage slot 12. A mounting base 221 is also provided at the front end of the midrange speaker 22, with mounting holes on the base. The midrange speaker 22 can be detachably mounted to the first side wall using bolts. Similarly, the woofer 21 can also be detachably mounted to the first side wall using bolts. Furthermore, neither the woofer 21 nor the midrange speaker 22 protrudes from the storage slot 12, effectively preventing damage from impacts.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the storage slot 12 is also provided with a storage opening 13, which is connected to the amplification cavity. The end of the bass speaker 21 facing away from the amplification end passes through the storage opening 13 and is placed in the amplification cavity. This makes full use of the space of the amplification cavity, effectively reduces the overall volume of the speaker, and allows the speaker to be installed in more locations, thus improving the application range of the speaker.
[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the speaker also includes a switch panel, which can be used to adjust the sound effects of the speaker. The top of the enclosure 1 is also provided with an assembly port 14, which is connected to the amplification cavity. The assembly port 14 is used for inserting and fixing the switch panel, and the mounting port 15 can also be used to organize and adjust the wiring of each speaker on the speaker, which facilitates the assembly of the speaker.
[0041] It should be noted that the enclosure 1 in this embodiment is composed of a top surface, a bottom surface, two first side walls and two second side walls. Any two adjacent planes are provided with curved chamfers, which enhances the structural strength of the enclosure 1 and avoids the situation where users are easily bumped and injured due to the sharp edges of the speaker.
[0042] like Figure 3 As shown, in this embodiment, the second sidewall has an installation port 15. The passive radiator 3 includes a body part 31, a buffer part 32, and a vibrating part 33 connected sequentially from the outside to the inside. The outer periphery of the body part 31 is connected to the inner peripheral wall of the installation port 15, and the buffer part 32 is made of a flexible material. The vibrating part 33 can be made of aluminum, which provides better sound amplification. Specifically, the body part 31 can be detachably connected to the installation port 15 or threadedly connected, as long as it allows for convenient assembly of the passive radiator 3 with the second sidewall.
[0043] Specifically, the buffer 32 can be made of rubber, which has good elastic deformation effect and can effectively ensure the low-frequency expansion of the passive cone 3, giving the passive cone 3 sufficient low-frequency depth. The buffer 32 and the vibrating part 33 are made of two materials with different audio characteristics. The passive cone 3 formed by this combination has rigidity, high internal resistance, low distortion, and high audio resolution. The passive cone 3 in this embodiment takes into account the effects of high frequency, mid frequency, and low frequency. The mid frequency is delicate and soft, the high frequency is transparent and bright, and the low frequency is open and dynamic.
[0044] In this embodiment, one of the two subwoofers 21 has a vibration frequency range of 45-350Hz, and the other subwoofer 21 has a vibration frequency range of 45-120Hz. Through an asymmetric low-frequency coupling algorithm, the phase and delay parameters are adjusted to fine-tune the subwoofers 21, increasing the sound pressure level in the overlapping frequency band of the two subwoofers 21. This widens the operating bandwidth of the speaker while ensuring good low-frequency extension. In this embodiment, the lowest audio frequency of the speaker can extend down to 40Hz, effectively enhancing the fullness of the low frequencies.
[0045] The size of the midrange speaker 22 ranges from 55mm to 75mm. In this embodiment, the two midrange speakers 22 are set to 65mm, which reduces their size while ensuring good mid- and high-frequency transmission. This facilitates storage within the storage slot 12, reducing the overall size of the speaker, and avoids interference between mid-, high-, and low frequencies caused by excessively large midrange speakers 22, thus preventing any impact on the overall sound quality. Furthermore, the low-frequency range can be compensated using GEQ sound effect adjustment, and the two woofers 21 and two midrange speakers 22 can be adjusted as a whole, allowing the lowest frequency of the speaker in this embodiment to extend down to 35Hz. The high-frequency range is appropriately attenuated to conform to the equal loudness perception curve, resulting in better sound quality.
[0046] In this embodiment, a car is also proposed, including the audio system described above. Since the car employs all embodiments of the audio system, it also possesses all the beneficial effects of the audio system, which will not be elaborated upon here.
