Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker basin frames, in particular to a loudspeaker basin frame provided with wiring rack holes. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of a speaker has a great influence on the sound quality. The speaker is the weakest device in audio equipment, but it is the most important component for sound effects. There are many types of speakers, and their prices vary greatly. Audio electrical energy vibrates its cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates (resonates) with the surrounding air to produce sound. When selecting a speaker, you should consider parameters such as the speaker's rated power, frequency response, directivity, and impedance. The rated power of a speaker refers to the undistorted power that the speaker can work at for a long time. Its nominal value is generally 1 / 2 of the maximum power the speaker can withstand. When the power of the speaker exceeds the rated power, its sound quality will deteriorate or even damage the speaker. Therefore, when selecting a speaker, the rated power of the speaker should be determined based on the area of ​​the listening room and the power of the power amplifier. The speaker basin frame is the "skeleton" of the cone speaker. The basin frame plays an important role. The basin frame can combine the diaphragm, folding ring, centering plate, magnet, magnetic conductive element, etc. to form a complete speaker system. In addition, the basin frame can also play a supporting and fixing role. The speaker is installed on the box to ensure the stability and safety of the speaker during use. When the speaker is working, the diaphragm will transmit the vibration to the folding ring, and the folding ring will transmit the vibration to the basin frame, and further to the box. This conduction will also proceed in the opposite direction, forming interference with other waves and producing complex vibration conditions. Therefore, the design and manufacture of the basin frame have an important influence on the sound performance of the speaker. However, in the prior art, the speaker basin frame is manufactured by one-piece stamping. During transportation, the basin frame may be slightly deformed due to collision, which in turn affects its use, resulting in large losses, and rust may occur when used for a long time. Rust not only affects the appearance of the basin frame, but also may affect its structural stability and performance. For this reason, we propose a speaker basin frame with a wiring rack hole.
