[0027] The following reference Figures 1 to 3 This application describes a speaker according to an embodiment.

[0028] A speaker according to an embodiment of this application, referring to... Figures 1 to 3 The system includes a housing 100, a sound output component, and an interface assembly. A cavity is formed within the housing 100. The sound output component includes a tweeter 210 and a woofer 220, which are positioned opposite each other in the upper part of the cavity. The reasonable positioning of the tweeter 210 and woofer 220 optimizes the bass effect, making the sound more three-dimensional, achieving a balanced sound output, and improving sound quality.

[0029] The interface assembly includes a main control board 330, several interface boards 310, a sealing component 320, and a rear cover plate 340. The sealing component 320 is disposed around the interface boards 310. The interface boards 310 and the sealing component 320 are disposed on the housing 100. The main control board 330 is disposed on the upper side of the interface boards 310, and the rear cover plate 340 is disposed on the bottom of the housing 100. The position of the rear cover plate 340 corresponds to the position of the interface boards 310. The upper and lower ends of the sealing component 320 are tightly fitted to the main control board 330 and the rear cover plate 340, respectively. The sealing component 320 is disposed around the interface boards 310, and the main control board 330, the sealing component 320, and the rear cover plate 340 can seal the top, sides, and bottom of the interface boards 310 to prevent sound leakage from the interface boards 310 and improve sound quality. In some embodiments, there are two, three, or more interface boards 310, and all two or more interface boards 310 are disposed within the sealing component 320, ensuring sealing while providing external output interfaces. The tweeter 210 and woofer 220 are arranged opposite each other in the upper part of the cavity. The interface plate 310 and the sealing component 320 are arranged on the housing 100. The tweeter 210 and woofer 220 are not arranged facing the interface plate 310, which can reduce the risk of sound leakage from the interface plate 310.

[0030] According to some embodiments of this application, the sealing component 320 includes four sealing surfaces, forming a sealing cavity between the four sealing surfaces, and the interface plate 310 is disposed within the sealing cavity. The sealing component 320 is disposed around the interface plate 310. Specifically, the sealing component 320 includes four sealing surfaces, forming a sealing cavity between the four sealing surfaces. The sealing component 320 seals the perimeter of the interface plate 310, the main control board 330 seals the top of the interface plate 310, and the rear cover plate 340 seals the bottom of the interface plate 310. This allows the interface plate 310 to form an independent cavity outside, within which an external output interface is located, without affecting the overall sealing performance of the speaker enclosure.

[0031] According to some embodiments of this application, the sealing component 320 is made of EVA sealing cotton. EVA sealing cotton has a certain degree of elasticity. The main control board 330 seals the top of the interface plate 310, and the rear cover plate 340 seals the bottom of the interface plate 310. The main control board 330 and the rear cover plate 340 work together to compress the sealing component 320, thereby improving the sealing effect. EVA sealing cotton is flexible, lightweight, has good density, and is highly elastic. When placed around the main control board 330 and the rear cover plate 340, it can act as a cushioning material. Placing EVA sealing cotton around the interface plate 310 also helps the interface plate 310 better absorb and disperse external impact forces, providing shock absorption and anti-friction.

[0032] According to some embodiments of this application, a vibration component 410 is further included. An opening 420 is provided on the side of the housing 100, and the vibration component 410 is disposed on the opening 420. The vibration component 410 is disposed on the side of the housing 100, and the opening 420 is provided on the side of the housing 100. The vibration component 410 engages with the opening 420 from the side to achieve a seal on the housing 100, effectively preventing sound leakage and improving sound quality. In some embodiments, the vibration component 410 includes an elastic isolator and a vibrator. The vibration component 410 can amplify the frequency of bass frequencies, increase the low-frequency response, and thus improve sound quality.

[0033] According to some embodiments of this application, a mounting post 110 is provided at the bottom of the housing 100, and an interface plate 310 is disposed on the mounting post 110. The mounting post 110 at the bottom of the housing 100 and the interface plate 310 mounted on the bottom of the housing 100, specifically, the interface plate 310 is disposed on the mounting post 110. The mounting post 110 and the interface plate 310 are aligned to ensure that the position of the interface plate 310 on the housing 100 is fixed, facilitating the locking of the interface plate 310 and the housing 100. In some embodiments, the mounting post 110 is provided with a mounting hole, and a threaded fastener passes through the mounting hole of the mounting post 110 and engages with the interface plate 310 to fix the interface plate 310 on the housing 100. In some embodiments, the mounting post 110 and the mounting hole can guide the threaded fastener, facilitating the connection and fixation of the main control board 330, several interface plates 310, and the rear cover plate 340 using the threaded fastener.

[0034] According to some embodiments of this application, a power supply assembly and a transformer component 530 are also included. The transformer component 530 is disposed on the housing 100, and the power supply assembly is disposed above the transformer component 530. The power supply assembly is used to supply power to the speaker, and the transformer component 530 is used to transmit electrical energy.

[0035] In related technologies, the transformer component 530 needs to generate a magnetic field, which can disturb surrounding circuits. If the transformer component 530 is close to the power supply, it will affect the operation of the power supply, causing unstable power output. This is because the magnetic field generated by the transformer component 530 will cause signal interference to the power supply wires. The magnetic field generated by the transformer component 530 will induce current in the wires, resulting in current interference. This interference will reduce the signal transmission quality, thereby affecting the operation of the power supply. In addition, current interference will also cause noise from the power supply, thereby affecting the normal operation of the equipment. According to some embodiments of this application, the power supply assembly includes a power board 510 and a bracket 520. The power board 510 is mounted on the bracket 520, and the bracket 520 is provided with multiple legs, with clearance portions formed between the legs to avoid the transformer component 530. The transformer component 530 is mounted at the bottom of the housing 100, and the bracket 520 is mounted at the bottom of the housing 100 via support legs. Multiple support legs form a clearance section, which allows the transformer component 530 to pass. The bracket 520 supports the power board 510. This design effectively utilizes space while preventing close contact between the power board 510 and the transformer component 530, thus preventing the transformer component 530 from interfering with the normal operation of the power board 510 and ensuring its long-term stable operation. It also prevents noise from the power board 510 from affecting the speaker's sound effect, ensuring optimal sound quality.
