Embodiment 1

[0028] Example 1, such as figure 1 As shown, the present invention includes a wireless music vibration body, at least one resonance sounding board 3 and a resonance sounding cloth 2 arranged in the wireless music vibration body; the first surface of the resonance sounding board 3 and the wireless music body The sound vibrator 11 on 1 is attached and arranged, and the second surface of the described resonance sounding board is attached to the inner surface of the described resonance sounding cloth; Outline composition settings.

[0029] The present invention adopts wireless signal transmission technology, and preferably uses Bluetooth wireless transmission technology to transmit the music source from the playback device to the wireless music module 16 of the present invention through the Bluetooth wireless signal, and then the wireless music module 16 converts the wireless signal to audio , Utilize the matching body of the resonant sounding board 3 and the resonant sounding cl...

Embodiment 2

[0034] Embodiment 2, based on the above embodiment, the present invention provides a new type of resonant sound panel audio, the difference between this embodiment and the above embodiment is: preferably, the number of the resonant sound board 3 is 2, each The first surfaces of the resonance sounding boards 3 are independently attached to at least one sound vibrator. The sound sources of the resonant sounding plate 3 and the sound vibrator 11 (sound exciter) of 2 groups are attached to the inner surface of the resonance sounding cloth 2 respectively, so that the effect of stereoscopic field sound quality can be improved within a limited range. Of course, it can also be more than two resonance sounding boards 3 .

Embodiment 3

[0035] Embodiment 3, based on the above embodiments, the present invention provides a new type of resonant sound panel audio, the difference between this embodiment and the above embodiments is:

[0036] The material of the resonance sounding board 3 is honeycomb paper. The hardness and lightness of the honeycomb paper meet the requirements. Compared with other various board structures, the honeycomb paper sandwich structure has the largest strength / mass ratio, and the honeycomb sandwich structure is approximately isotropic, has good structural stability, is not easy to deform, and has Outstanding compressive and bending capabilities;

[0037] The material of the resonant sounding cloth 2 is nylon. Can also be fabric, the material of nylon and fabric is softer, more meets the condition of resonance pronunciation.

Abstract

The invention relates to a novel resonance sounding flat loudspeaker which comprises a wireless music vibration body, at least one resonance sounding board arranged in the wireless music vibration body and a piece of resonance sounding cloth; the first surface of the resonance sounding board is attached to a sound vibrator on the wireless music body, the second surface of the resonance sounding board is attached to the inner surface of the resonance sounding cloth; the resonance sounding cloth is combined with the outer frame of the wireless music body with the tensile force of 5kg-20kg. The resonance sounding board is matched with different audio resonance points of the resonance sounding cloth to produce a flat loudspeaker sounding device of full range.

Description

technical field [0001] The invention relates to a sound, in particular to a novel flat-panel sound with resonant sound. Background technique [0002] The sounding principle of traditional speakers is to touch the diaphragm through the generation of electrical signals to produce sound. The basic principle comes from Fleming's left-hand law. Put a current-carrying wire perpendicular to the magnetic force line between the north and south poles of the magnet, and the wire will be affected by the magnetic force line. The interaction between the current and the current moves, and when a diaphragm is attached to the wire, the diaphragm moves back and forth as the current changes. As the diaphragm moves and vibrates, the surrounding air is pushed to vibrate, and the speaker produces sound. But the volume of the loudspeaker box is generally relatively large, especially its thickness is large, the floor area is also large, the appearance is heavy, and it is not beautiful, and the pla...
