(5) Implementation, function and advantage of the invention will be further described combining with embodiments and according to drawings.
DETAILED DESCRIPTION OF THE INVENTION
(6) 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.
(7) Embodiment 1 is shown as
(8) 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.
(9) 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).
(10) 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).
(11) 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 mm×80 mm.
(12) 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.
(13) 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.
(14) Embodiment 2, base on above embodiment, the invention provides a resonance flat panel 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.
(15) Embodiment 3, base on above embodiments, the invention provides a resonance flat panel speaker, the difference between this embodiment and above embodiments is: material of said resonance sounding board (3) is honeycomb paper.
