Description
Technical field
The present invention relates to a kind of multimedia interactive system devices, particularly relate to a kind of mute ultralow frequency sound wave multimedia interaction
System and device.
Background technique
It is known extensively in recent years with the resonance music of frequency with E.E.G, many larger medical institutes have recognized that and by it
It introduces to reach as medically auxiliary user and sets the mind at rest, develops potential, helps for sleep and other effects.According to existing mode,
User reaches effect by the music for listening to capable of emitting particular frequencies, however the sound wave of the frequency due to that can resonate with E.E.G
Belong to ultralow frequency range, is not the frequency range that general sound appliances can be generated directly.
When two sound sounding simultaneously, physically other than respective frequency, phase between also generating
The frequency of difference.When the frequency of two sound closer to when, generated frequency difference is lower, with this principle when with electronic instrument precision fortune
Calculate two-way audio and by amplification be output into sound signal when, be that can produce ultralow frequency sound with E.E.G with frequency by frequency difference
Wave.
Since such frequency difference is in acoustically belonging to a kind of special sound equipment, all sense of hearing acoustics for belonging to particular color,
Logic according to musical composition is then not appropriate for all types of music, and due to the particular color of its sound, the happiness of hearer
Good also inconsistent with acceptance, some audiences are discordant to feeding back after the listening of such music；Thus while it has and E.E.G
The effect of with frequency, the popularization in application and popularizations have its range and limitation.
If traditional mode is intended to reinforce the ultralow frequency frequency range to be generated in a manner of being overlapped and put, due to where frequency
And the multiple overtone above the discordant root of original generated is overlapped interference, certainly will generate quite discordant noise and allow
People steps back to this sound, thus can not enhance the ultralow frequency frequency range for being intended to reinforce with this stacked system.And traditional mode institute
The sound wave of generation is easy to generate standing wave in the interior space, will be even more serious via the standing wave situation after superposition, will aggravate
The interference of acoustic noise.
In addition, non-general playback equipment can directly be reached if generating ultralow frequency in a manner of supersonic, and due to
Its with music player is non-is integrated, cannot also reach the function such as design for expanding and adjusting in real time ultralow frequency setting with music content
Effect.
Therefore, before the present inventor the problem of in view of prior art, creates TaiWan, China patent No. M538390 " one
Kind can be used to generate mute ultralow frequency sound wave generation device ".
Currently, not can produce mute ultralow frequency sound wave sleeping timing timing etc. commodity because on the market be not
It is made in a manner of sound wave.
In addition, some are complicated about the commercial product production method of E.E.G resonance at present, such as the easypro dormancy Schumann of the love of ITRI
Resonance, which is relaxed, presses regular movements bed (chair) service system.
The mute mode commonly used is a certain amount of since high frequency has, and is not suitable for the occasion for the quiet sleep for being used in short distance, and
Intensity is weaker.
The shortcomings that summary, existing E.E.G resonance instrument equipment is that production demand is high, due to the more electronic circuit of demand
Element, electromagnetic wave is also easily with respect to relatively strong.
Then, the present inventor is that research and development are thought with great concentration in line with the practical experience for being engaged in product design, exploitation for many years, and actively
It examines, via actual test many times, experiment, cause has generation of the invention.
Summary of the invention

The piezoelectric material ground cushion 9 can produce electricl energy after being trampled, to supply electric power of the invention.
In a constructed embodiment, which is selected from high-frequency resonance material of good performance.
In a constructed embodiment, the piezoelectric material ground cushion 9 set multiple LED light 91 or can sounding loudspeaker (not shown).
Above-mentioned is composition introduction of the invention, then again by each portion's component of the invention and its building form introduction, then
Use embodiment of the invention, feature, benefit are described below again:
Sonic waveforms frequency values caused by the first general waveform generator 1 and the second general waveform generator 2 are at least
For 8k hertz (Hz).
It can be used to lead to from the first general waveform generator 1 with second using the first signal integral unit 3
(mixing) is integrated with the audio of waveform generator 2 and generates one " difference on the frequency " (P1-P2), is generated using the difference on the frequency
Meet the ultralow frequency sound wave of usually possible frequency of brain wave range.
And the audio that the effect device 4 can be used to after operation integration becomes audio to change its sound property, the effect
Device 4 can be used but be not limited to universal space effect, and can generate the effect of such as reverberation (Reverb).It is put by the general purpose signal
Big device 6 amplifies audio, output to loudspeaker 7.2 institute of the first general waveform generator 1 and one second general waveform generator
The higher part of the audio respectively generated still may generate ultralow frequency sound wave (because the difference on the frequency is exactly with the difference on the frequency
Ultralow frequency) and be passed.
Therefore, which is isolated a suction strainer audio layer 8, which is able to the outer noise of suction strainer, and should

Whole sound waves is avoided to be wrapped by or absorb.
Difference on the frequency generation ultralow frequency sound wave penetrance is higher and can penetrate out the loudspeaker 7, and the first general wave
Higher partial adsorbates of audio that shape generator 1 and one second general waveform generator 2 respectively generate and filter out.Such one
Come, more pure ultralow frequency sound wave can be obtained.
And sound is leaked in order to prevent, suction strainer audio layer 8 can extend the IC plate being coated to close to system and device of the invention.
The present invention (can also detect the reversed of audio to dial further combined with developed scene noiseless design in real time in recent years
Put), such as external loudspeaker is connected with low-power consumption bluetooth, so that loudspeaker is played reversed noise reduction sound wave, to reduce spatial noise, or
General music file is played all may be used.
The present invention has the characteristics that at least following:
It is manufactured 1. being easily achieved, low electromagnetic wave (because circuit is simple, EMI Electromagnetic Interference is relatively low), without angry
The audio of people is not necessary to plug-in or charging.
2. when (child) plays game or stair, elevator, not stopping to trample in front of the door etc. and producing electricl energy, the audio being simultaneously emitted by is also
It may be configured as the help of alpha wave band to loosen.In addition, being environment if can more reduce the noise of game sending in conjunction with de-noising mixer
Friendly device.
In the above are the present invention for embodiment, only for ease of illustration and set, when the meaning that the present invention cannot be limited in this way
Justice, i.e., all various shift designs according to carried out by claim, should be included in the scope of the patents of the invention.
