Embodiment Construction

[0017] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0018] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a sound quality control structure, including: a resonant sound emitting unit 1 and a vibration absorbing unit 2 .

[0019] The resonant sound unit 1 includes a resonant plate 11 and a resonant horn 12, the resonant horn 12 is correspondingly arranged on the resonant plate 11, and is used to vibrate the resonant plate 11 to emit sound, and the resonant plate 11 is set There is a fixed seat 13 for placing the resonant horn 12, and fixing the resonant horn 12 so that it is firmly attached to the resonant plate 11. When the resonant horn 12 is taken out from the fixed seat 13, it can Stopping the resonance horn 12 from vibrating the resonance plate 11 is convenie...

Abstract

The invention provides a resonance broadcast display billboard which comprises a tone quality control structure, wherein the tone quality control structure comprises a resonance sounding unit and a vibration absorbing unit, wherein the resonance sounding unit comprises a resonance plate and a resonance loudspeaker; the resonance loudspeaker is correspondingly arranged on the resonance plate for vibrating the resonance plate to generate sound; the vibration absorbing unit comprises a hollow vibration absorbing part and a water injection unit; the hollow vibration absorbing part is attached to the resonance plate; the water injection unit is connected with the hollow vibration absorbing part and is used for injecting water into the hollow vibration absorbing part; thus, different quantity ofwater is injected into the hollow vibration absorbing part so that the hollow vibration absorbing part correspondingly has different vibration absorbing effects, and the resonance plate is vibrated by the resonance loudspeaker so as to correspondingly make different tone quality. According to the resonance broadcast display billboard in the invention, the water quantity can be adjusted accordingto the display field so as to control the tone quality and the volume and achieve a proper advertisement display effect.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a resonant broadcast display billboard. Background technique [0002] In the prior art display effect with patterns and sounds, the light from the light source is evenly reflected to the display board by the reflective plate, so that the brightness is averaged and a good display effect is produced. However, its sound is displayed through the existing music player, and its use must be limited by the power supply of the exhibition site, and its sound quality cannot be further changed, so it is relatively inconvenient to display. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a resonant broadcast display billboard to solve the above technical problems. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a resonant broadcast display billboard, including a sound quality...
