Embodiment 1

[0013] An anti-shock and anti-interference sound column, comprising a box body 1, a power amplifier, and a loudspeaker 2; it is characterized in that: the inside of the box 1 is provided with a power amplifier, and the power amplifier is connected to multiple groups of loudspeakers 2, and the loudspeaker 2 is set On the front panel of the box body 1, an anti-vibration glue 3 is provided between the loudspeaker 2 and the panel of the box body 1; each joint between the box bodies 1 is provided with an anti-shock glue 3.

Embodiment 2

[0015] The working principle of the present invention: add anti-vibration glue 3 to each joint of the box body 1, reduce the resonance generated by the sound column during work, eliminate mechanical noise, and purify the sound quality and volume; and the anti-shock glue 3 between the loudspeaker 2 and the panel of the box body 1 It can greatly reduce the vibration of pronunciation, and at the same time reduce the frequency of vibration transmitted from the power amplifier, effectively reducing mechanical noise and impurities.

Abstract

The invention discloses a shockproof and anti-interference sound post. The sound post comprises a box body, a power amplifier and loudspeakers. The sound post is characterized in that the power amplifier is arranged in the box body, the power amplifier is connected to multiple groups of loudspeakers and the loudspeakers are arranged on a front side panel of the box body; shockproof glue mud is arranged between the loudspeakers and a box body panel; and connection portions of the box body are provided with the shockproof glue mud. The shockproof and anti-interference sound post possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; the sound post has shockproof and anti-interference functions and so on. The sound post possesses a high practical value.

Description

technical field [0001] The invention relates to a sound column, in particular to a shockproof and anti-interference sound column. Background technique [0002] The so-called sound column generally has more than two speakers arranged in an array to produce a flat sound field. Within a certain listening range, the sound attenuation is much lower than that of a point sound source. For example, at a listening distance of 5m, the point sound source attenuates by about 14dB, while the attenuation of a well-designed sound column is only 7dB, which follows a double gap, so the farther the distance is, the more obvious the gap will be. Of course, this is also achieved within the effective range of the plane field of the sound column. For specific information, please refer to some books on acoustics. The advantage of this is that within a certain listening distance, the proportion of direct sound greatly exceeds that of reflected sound (or ambient sound), so that the impact of th...
