Receive the size difference of basin 121, concave acoustic wave energy absorbs the material difference of basin 121 and concave acoustic wave energy absorbs basin 121
Counterweight is different, then the predeterminated frequency that can trigger the concave acoustic wave energy absorption generation resonant frequency of basin 121 is also different, for example,
The counterweight that concave acoustic wave energy absorbs basin 121 is larger, and predeterminated frequency then wants lower.In the present embodiment, predeterminated frequency can be with
Concave acoustic wave energy then may make to absorb basin in the predeterminated frequency less than the 150Hz for the frequency of 150Hz, that is, sound
121 generate the resonance of same frequency, but are not intended as limiting the present embodiment.In the manner described above, this field in actual implementation
The adjustable predeterminated frequency for triggering the concave acoustic wave energy and absorbing 121 starting of oscillation of basin of technical staff, for example, increasing counterweight by default frequency
Rate is reduced to 120Hz.Further, in the present embodiment, concave acoustic wave energy, which absorbs basin 121, to be also had with the minimum of disengaging resonance
Frequency, for example, the low-limit frequency can be with 20Hz.That is, after the frequency of sound wave is less than the low-limit frequency, concave sound wave energy

For hollow barrel-like structure, for example, being hollow cylinder-like structure.It is certain around being arranged on the barrel of induction coil cylinder 122
The induction coil of the number of turns.Wherein, the number of turns of the induction coil can be selected according to actual needs, for example, needing to generate
The voltage of electric energy more greatly, then the number of turns then can be more, conversely, then a little less.Induction coil cylinder 122 then with concave sound wave
The second end 1212 of energy absorption basin 121 connects, wherein connection can be to be achieved a fixed connection by the way of such as stickup.
In the present embodiment, induction coil cylinder 122 and concave acoustic wave energy absorb basin 121 and connect and formed cooperation, therefore induction coil cylinder
122 size should absorb the size fit of basin 121, but the specific size of induction coil cylinder 122 this reality with concave acoustic wave energy
It applies example and is not specifically limited, meet the actual needs.
Annular magnet 123 is the cyclic structure made of magnetic material.It the edge of annular magnet 123 can be with cavity
111 connections, but the present embodiment does not limit the connection type of itself and cavity 111 specifically, and satisfaction can be by annular magnet 123
Connection.Annular magnet 123 is set on induction coil cylinder 122, i.e. the inner ring of annular magnet 123 is set in the line of induction
It encloses on cylinder 122.Further, it can be moved for ease of the induction coil on the induction coil cylinder 122 and realize cutting annular magnetic
Magnetic induction line caused by iron 123, then the size of the inner ring of annular magnet 123 can be slightly over the ruler of induction coil cylinder 122
It is very little, so that the inner ring of annular magnet 123 is arranged the induction coil cylinder 122 but is not contacted with the induction coil cylinder 122 formation.
Further, in the acoustic wave energy absorptive unit 120 of the present embodiment, basin 121 is absorbed in concave acoustic wave energy
Recess is when being absorbed into low-frequency sound wave of the SIF sound intermediate frequency rate less than predeterminated frequency, for example, the film plot shown in home theater
The plot of bomb blast is arrived, to the low-frequency sound wave less than predeterminated frequency that bomb blast sound then will produce in film plot.
The energy of the low-frequency sound wave enables to concave acoustic wave energy to absorb basin 121 and generates resonance identical with the low-frequency sound wave frequency,
For example, the resonance that concave acoustic wave energy absorbs basin 121 makes concave acoustic wave energy absorb basin 121 with identical with the low-frequency sound wave
Frequency moves reciprocatingly.Since induction coil cylinder 122 and the concave acoustic wave energy absorb the connection of basin 121, the induction coil cylinder
122 also absorb the reciprocating motion that same frequency resonance is done in the drive of basin 121 by meeting concave acoustic wave energy.That is, at this point, this is low
The energy of frequency sound wave is converted by the reciprocating motion that concave acoustic wave energy absorption basin 121 recess and induction coil cylinder 122 resonate
At kinetic energy.Further, it moves back and forth caused by the kinetic energy which then generates according to resonance and makes sense
The magnetic induction line for answering coil cutting annular magnet 123 to generate cuts the magnetic induction line of the generation of annular magnet 123 then by reciprocating motion
The electric energy that the exchange of the corresponding resonant frequency is produced in induction coil again will to the induction coil of induction coil cylinder 122
The electric energy exports.
It please refers to Fig.1 to Fig.4, it can be N number of to prompt the quantity of output unit 130, and N number of prompt output unit 130 is right
It should be connect with N number of acoustic wave energy absorptive unit 120 in M acoustic wave energy absorptive unit 120, and N is just whole no more than M
Number.That is, when N is equal to M, then each acoustic wave energy absorptive unit 120 can prompt output list corresponding with one
Member 130 connect, electric energy can be exported from each acoustic wave energy absorptive unit 120 to this to one prompt output unit
130.But when N is less than M, have in M acoustic wave energy absorptive unit 120 M-N acoustic wave energy absorptive unit 120 can not with it is right
The prompt output unit 130 answered connects, then for the M-N acoustic wave energy absorptive unit 120, M-N acoustic wave energy is inhaled
It is entirely then to be discharged after the energy of low-frequency sound wave is converted into kinetic energy, and realize low-frequency sound wave energy to receive unit 120
Absorption.
Specifically, for for N number of prompt output unit 130, each acoustic wave energy is inhaled in N number of prompt output unit 130
It is essentially identical, for ease of description clear to receive the installation principle of unit 120 and operation principle, and convenient for art technology
