Technical field
The present invention relates to electronic music apparatus field, especially, it is related to a kind of desktop speaker.
Background technology
Desktop speaker is a kind of universal computer peripheral equipment, has generally comprised power amplifier and audio amplifier；In order to meet user day
The temperament and interest requirement that benefit is improved, some current desktop speakers include internal landscape；Typically, such as fountain audio amplifier, it is mainly wrapped
Audio amplifier matrix, and the landscape casing being implemented on audio amplifier matrix are included, landscape casing is the transparent cabinet of closing, and bottom contains water
Body, and it is provided with nozzle, water pump；The driving current of water pump is coupled in the tone currents of audio amplifier；Thus, the driving current of water pump with
Music and consecutive variations；In the process, water pump makes the water column sprayed upwards from nozzle for the driving force consecutive variations of water body
Consecutive variations.
However, in actual use, due to the inertia of pump motor rotor, the rotating speed of water pump drives electricity for water pump
The change of stream has time lag；And water body also has larger inertia in itself, the motion of water body becomes relative to the rotating speed of water pump
Change and there is time lag again；This causes the water column sprayed by nozzle poor for the expressive ability of music；Reaction under normal circumstances
It is that when volume is smaller, water column is being maintained at relatively low level, and volume, when increasing to certain level, water-column rises suddenly and sharply suddenly,
And it is maintained at higher level；It is extremely difficult to make water column follow music to make grazioso to rise and fall.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of desktop fountain landscape audio amplifier, the fountain landscape audio amplifier
Fountain landscape can be formed, and makes its fountain water column follow music rolling exactly, to improve artistic expression.
The technical solution adopted for the present invention to solve the technical problems is：The desktop fountain landscape audio amplifier includes power amplifier, sound
Case；The audio amplifier includes audio amplifier matrix, and the landscape casing being implemented on audio amplifier matrix；The landscape casing is enclosed by transparent shell
Into, bottom contains water body, and provided with nozzle, driving water pump；The water inlet end of the driving water pump is in below water body, and water side leads to
Cross isocon and be communicated to each nozzle；The driving water pump is operated when detecting tone currents with invariable power；The nozzle
Including rubber short tube, and it is surrounded on the control assembly of rubber short tube；The control assembly is fitted in outside rubber short tube including 2
The tile-type silicon steel sheet of wall, and surround the rubber short tube, the solenoid tube of tile-type silicon steel sheet；The solenoid tube include base tube and around
The magnet exciting coil being placed in outside base tube, the magnet exciting coil is coupled in the tone currents of the audio amplifier matrix by amplification module.
Preferably, the input of the driving water pump is coupled in tone currents by positive feedback amplification module, i.e. so that
The input of audio amplifier matrix exports tone currents as the input current of the positive feedback amplification module, and amplifies the positive feedback
Module works in saturation output state all the time by positive feedback amplification mechanism.
Preferably, the base tube of solenoid tube is made up of non-magnetic short tube in the control assembly, to reduce base tube for institute
State the magnetic attraction of tile-type silicon steel sheet.
Preferably, further respectively having a bandpass filtering modules block between each magnet exciting coil and the amplification module；
So that the power frequency of different magnet exciting coils is different；Accordingly, for the music in broadcasting, its frequency included is different,
It is then also different in response to the nozzle of music；Such as, when the low-frequency component included in current music is more, with low frequency bandpass filtering modules block
The response that the nozzle being coupled rises and falls for music is more sensitive, and the radio-frequency component included in current music it is more when, with high frequency
The response that the nozzle that bandpass filtering modules block is coupled rises and falls for music is more sensitive；I.e. so that whole fountain landscape audio amplifier is not only
The volume of music can be followed to rise and fall, while also being responded to the spectrum signature of music；Further increase its artistic expression
Power.
The beneficial effects of the present invention are：Operationally, tone currents is directly acted on respectively the desktop fountain landscape audio amplifier
On the magnet exciting coil of nozzle exterior, make to form axial fluctuating magnetic field at each nozzle, the axial fluctuating magnetic field is to the rubber short tube
The tile-type silicon steel sheet of periphery carries out excitation, the magnetic attraction between the two panels tile-type silicon steel sheet being mutually directed to is connected with the fluctuating of music
Continuous fluctuation, so as to carry out continuous fluctuation-type extruding to rubber short tube, when volume increases, the transverse pressure of rubber short tube increases
Greatly, deformation increase, makes water-column become big, and when volume down is small, rubber short tube transverse deformation reduces, water-column reduction；By
In tile-type silicon steel sheet small volume, inertia is small, and the response risen and fallen for music is extremely fast, and the motion of tile-type silicon steel sheet is direct
Change the cross section of water column, make water-column and tile-type silicon steel sheet, music almost synchronously change, can make fountain water column exactly with
It is rolling with music.
