An inverted speaker

Abstract

The invention discloses a phase-reversing sound box, which comprises a sound box body (1); the sound box body (1), the shell back shell (2) and the shell front cover (7); the shell back shell ( 2) An arch-shaped inverter tube (3) is fixed inside, and the left and right ends of the inverter tube (3) face the bottom of the shell rear shell (2); the left and right ends of the inverter tube (3) A cavity shell (4) for installing a loudspeaker is respectively provided at both ends, and the left and right ends of the inverter tube (3) protrude out of the cavity shell (4); the shell rear shell (2 ) is provided with an opening (201) on the back, and a notch (303) is opened on the inverter tube (3) between the two cavity shells (4), and the opening (201) and the notch (303) There is a channel (5) between them; the opening (201) is in sealing communication with the notch (303) through the channel (5). The invention has the advantages of clean bass and deep low frequency.

Description

technical field [0001] The field of the invention relates to a vented loudspeaker. Background technique [0002] The speakers on the market use the diaphragm of the speaker. The diaphragm includes paper and plastic. No matter what its material is, when the speaker is working, the diaphragm will move back and forth continuously to push the air, and then push the air. The vibrations are transmitted to the human ear, allowing the person to hear the sound. Ordinary inverted speakers expose the speaker diaphragm to the outside to produce sound, and the rear of the speaker will also vibrate. If the vibration of the speaker to the rear is also used, the sound waves will be strengthened, and the subwoofer will be strengthened. Later, since the diameter of the inverter tube is smaller than that of the speaker, relatively strong sound waves will rush out from the inverter tube. In this way, the sound waves to the front and rear of the speaker are used, which improves the sound qualit...

AI Technical Summary

Problems solved by technology

The sound wave comes out from the loudspeaker and directly enters the inverter tube. Because the cross section of the inverter tube is arc-shaped, and the axis of the inverter tube transitions smoothly, the inner cavity of the inverter tube has almost no edges and corners, which can reduce the diffraction phenomenon of sound waves at the corners. To the lowest, the sound wave refraction is reduced to the lowest, it is not easy to cause the defects of the mid-frequency band response bee valley, the directivity of the mid-high frequency is narrowed, and it is not easy to produce harmful standing wave components, so that the diffusion performance of the mid-high frequency is significantly improved. Lack of speaker shell, after a long time of use, it will affect the whole and its various parts of the speaker or the joints of each part, prone to dust, affecting the service life of the speaker, dust entering the speaker, and at the same time affecting the sound quality of the speaker
