DETAILED DESCRIPTION OF THE INVENTION

[0025] Below further describe the invention combining with drawings and embodiments. The embodiments describe herein are only used for explaining the invention, but not to limit the invention.

[0026] Embodiment 1 is shown as FIG. 1, the invention comprises wireless music vibration body, at least a resonance sounding board (3) and a piece of resonance sounding cloth (2) arranged in said wireless music vibration body; the first surface of said resonance sounding board (3) is attached to the sound vibrator (11) on said wireless music body (1), the second surface of said resonance sounding board is attached to the inner surface of said resonance sounding cloth; said resonance sounding cloth is combined with the outer frame of said wireless music body with the tensile force of 5 kg-20 kg.

[0027] The invention uses wireless signal transmission technology, and preferably use Bluetooth wireless transmission technology to transfer music source from player device to wireless music module (16) of the invention, then said wireless music module (16) will convert the wireless signal to audio frequency, use the integration of resonance sounding board (3) and resonance sounding cloth (2) of the invention to play the sound.

[0028] Sound vibrator (11), resonance sounding board (3) and resonance sounding cloth (2) constitute a replaceable resonance sounding component, when sound vibrator (11) makes the sound output into frequency vibration, this vibration leads said resonance sounding board (3) and said resonance sounding cloth (2) to vibrate at the same time which turn into a resonance sounding system. Said resonance sounding cloth (2) is combined with said outer frame (12) with the tensile force of 5 kg-20 kg, some strength is needed to combine said resonance sounding cloth (2) with said frame (12). Nevertheless, too much strength will shorten the lifetime of said resonance sounding cloth (2), too little will affect the resonance effect of said resonance sounding cloth (2). Preferably, said tensile force is 10 kg. After many tests, 10 kg tensile force is the most appropriate when using the resonance sounding board 80 mm80 mm. For different frequencies, the material ingredient and hardness of said resonance sounding board (3) and said resonance sounding cloth (2) will have different resonance effects, the general music is in the frequencies between 20 KHz (high) and 80 KHz (low), the frequencies 180 Hz or below (low) will not generate obvious resonance. Instead, said resonance sounding cloth (2) is soft material, it can generate very obvious resonance sound for the frequencies under 180 Hz (low), but for the frequencies 180 Hz or above (high-mid), there will not be obvious resonance.

[0029] Put two resonance components with different materials together to constitute a part of complete resonance sounding component, it uses the advantage of two different materials, and let them complement each other, in order to resonate the music with full range (high-mid, low) effect.

[0030] Embodiment 2, base on above embodiment, the invention provides a novel resonance sounding flat speaker, the difference between this embodiment and above embodiment is: preferably, quantity of said resonance sounding boards (3) is two, the first surface of each said resonance sounding board (3) is individually attached to at least one said sound vibrator. The sound sources of 2 sets of said resonance sounding boards (3) and said sound vibrator (11) (sound exciter) are respectively attached to inner surface of resonance sounding cloth (2), thus improve the 3D sound effect in a limited range. Of course, the quantity of resonance sounding boards can be more than two.

[0031] Embodiment 3, base on above embodiments, the invention provides a novel resonance sounding flat speaker, the difference between this embodiment and above embodiments is: material of said resonance sounding board (3) is honeycomb paper. The hardness and lightness of honeycomb paper meet the requirement, in comparison with other board structures, the honeycomb interlayer has the largest intensity/mass ratio, its structure is similar to isotropy, has good stability that will not deform easily, has outstanding anti-pressure ability and anti-bending ability; the material of said resonance sounding cloth (2) is nylon, also can be fabric, nylon and fabric are soft which meet the condition of resonance sounding.

[0032] Embodiment 4, base on above embodiments, the invention provides a novel resonance sounding flat speaker, the difference between this embodiment and above embodiments is: the distance between said sound vibrator (11) and said frame (12) is at least 20 mm, in order to be convenient for production and ensure the resonance sounding board (3) and resonance sounding cloth (2) can generate effect. When said frame (12) has different sizes, the size ratio of resonance sounding board (3) can be adjusted to ensure the output tone quality and power.

[0033] Embodiment 5, base on above embodiments, the invention provides a novel resonance sounding flat speaker, the difference between this embodiment and above embodiments is: said wireless music vibration body also comprises a back plate, said back plate is used to protect each component in said wireless music vibration body (1); as shown in FIG. 2, said back plate (13) is installed on said frame (12), said back plate (13) has hanging hook (131) or anti-vibration pad, in order to install the flat speaker on the wall easily, significantly save the room space. Besides, different personalized art patterns can be printed on the surface of resonance sounding cloth (2) to make the ornamental value of this invention higher. The wireless music module (16) on said wireless music vibration body (1) which can send music source to said sound vibrator (11) connects with charging battery (15). The control button (14) and charge interface on said wireless music vibration body (1) all connect with said wireless music module (16), and set at the edge of the frame (12). The range of length and width of said resonance sounding board can respectively be 80 mm-250 mm. The invention takes 250 mm length and 80 mm width as an example, it realizes a very good technical effect. Wherein, the installation method of above said honeycomb paper and resonance sounding cloth is: the honeycomb cavity is set preferably perpendicular to said resonance sounding cloth, the material of said resonance sounding board may not be honeycomb paper, it can be honeycomb board with similar structure which made by other materials, two surfaces of this honeycomb paper are respectively covered by a thin cover plate (32), there are one by one honeycomb cavities (31) in the cover plate (32), the shape of these honeycomb cavities (31) may not be hexagon, they can be pentagon, quadrangle and etc, can also realize the purpose of resonance amplifying.

[0034] Preferably, thickness of said resonance sounding board is 2 mm, in this case, the tone and amplifying effect of said flat speaker are the best, and the flat speaker will not be obese.

[0035] The invention utilizes related sound vibrator sounding device, uses the vibration and resonance characteristics of different materials and match them together to produce the sounding device of flat speaker. Utilize the high-mid to high frequency range resonance point of hard material to make resonance sounding board (3), wherein the hard material of said resonance sounding board (3) needs to be light, in order to attach with other materials easily and effectively. Utilize the low frequency resonance point of soft material to make resonance sounding cloth (2), said resonance sounding cloth (2) needs to have appropriate stretching force and tensile force, in order to attach with said resonance sounding board (3) and provide effective sound. Different resonance points of said resonance sounding board (3) and said resonance sounding cloth (2) coordinate together to produce full range flat speaker sounding device. As the flat speaker uses flat structure resonance component, the structure of speaker is very compact, the size is relatively small which can significantly save the room space, and the costs of materials are cheap, it is easily widely promoting the use.
