Description
The application is that application No. is the divisional applications of 2015101212666 entitled improved-type fountain landscape speakers.
Technical field
The present invention relates to speaker fields, are to be related to a kind of landscape type speaker with music fountain particularly.
Background technique
With the raising of quality of the life and temperament and interest demand, the ornamental value of desktop electronic equipment is also increasingly particular about；Currently, having
A kind of landscape type speaker has music fountain, and the construction of the music fountain mainly includes a transparent sealing frame, the sealing
Envelope has liquid in frame, and with the fluctuation of music, liquid forms the music fountain of fluctuation-type in sealing frame.It is current this to have
The landscape type speaker of fountain, injection torrent are driven by motor drag water pump, and an existing serious problem is, by
In when electric current is smaller, the revolving speed and electric current of motor are non-linear relations, and the non-linear relation is close to opening up parabolic
Line relationship, this causes the height of fountain torrent that can not be proportional to volume, and external manifestation under normal conditions is, volume compared with
Hour, fountain torrent hardly occur, and when volume is somewhat larger, the height of fountain torrent just increases rapidly, and impacts soon
To the top of sealing frame, to be difficult to show the fluctuating of music.
Summary of the invention
In view of the above-mentioned problems, having in the speaker the purpose of the present invention is to provide a kind of improved-type fountain landscape speaker
Music fountain, and the fluctuating of fountain torrent and music have preferable linear dependence.
The technical solution adopted by the present invention to solve the technical problems is: the improved-type fountain landscape speaker include pedestal,
Motor, water pump, water tank include the first power amplifier module in the pedestal, and first power amplifier module is exported to loudspeaker；It is described
First power amplifier module is exported simultaneously to a current processing chip by input current extraction of square root processing, the current processing chip
To the second power amplifier module, second power amplifier module is exported to the motor for output, water pump described in the motor driven, the water
Pump drives the water body in the water tank to pass upward through spray orifice and forms fountain torrent.
Preferably, the motor is electrodeless variable-speed motor.
Preferably, the loudspeaker includes high pitch loudspeaker and woofer；First power amplifier module is by dividing
It exports after frequency device to the high pitch loudspeaker and woofer.
The beneficial effects of the present invention are: the improved-type fountain landscape speaker at work, amplifies through the first power amplifier module
The tone currents of output is handled through extraction of square root；And the revolving speed of motor and input current substantially parabolically functional relation, work as audio
After the processing of electric current evolution, then the parabolic function is substituted into, then its most high-order term can be made to be modified to once function drop time
, i.e. linear term, so make tone currents and motor speed closer to linear relationship, that is, improve the fluctuatings of fountain torrent with
The linear dependence of music.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of common fountain landscape speaker.
Fig. 2 is the structural schematic diagram of this improved-type fountain landscape speaker.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
It mainly include power amplifier module 1, the motor 2, water of sequential connection in common fountain landscape speaker shown in Fig. 1
Pump 3, water tank 4.After tone currents amplifies via power amplifier module 1, it is delivered directly to motor 2, then water pump 3, water pump are driven by motor 2
3 push up the water in water tank 4, form fountain torrent by spray orifice.During this, due to tone currents and 2 revolving speed of motor
In the functional relation of near parabolic, e.g., if tone currents is I0, motor speed n, then I0With n have approximately as pass
System: n=a I0 2+b I0+ c, wherein a, b, c are constant；In the case, tone currents I0When very little, n variation is smaller, and
With I0Increase, n speedup is getting faster.
And the structure of this improved-type fountain landscape speaker is as shown in Fig. 2, include pedestal (not shown), motor 2, water pump 3, water
Case 4 includes the first power amplifier module 11 in the pedestal, the output of the first power amplifier module 11 to loudspeaker (not shown)；Institute
It states the first power amplifier module 11 while exporting the current processing chip 13 for handling input current extraction of square root to one, at the electric current
The output of chip 13 is managed to the second power amplifier module 12, to the motor 2, the motor 2 is driven for the output of the second power amplifier module 12
The water pump 3, the water pump 3 drive the water body in the water tank 4 to pass upward through spray orifice and form fountain torrent.
By this scheme, which at work, amplifies the audio of output through the first power amplifier module 11
Electric current I0It is handled through extraction of square root, obtains primary correcting current I1=I0 1/2, primary correcting current I1Amplify through the second power amplifier module
It is afterwards secondary correcting current I2=k I0 1/2, wherein k is amplification factor, is constant；Then by I2Replace I0, substitute into relational expression n=a
I0 2+b I0After+c, n=ak is obtained2I0+b k I0 1/2+ c, due to I0It is smaller, therefore b k I0 1/2Influence it is smaller, can ignore,
Obtain approximate relation: n=ak2I0+ c, since a, k, c are constant, so motor speed and tone currents I at this time0It is similar to
Linear relationship.Therefore, this improved-type fountain landscape speaker improves the fluctuating of fountain torrent and the linear dependence of music.
In order to ensure that above-mentioned theory calculates resulting linear relationship in mechanical properties, the motor 2 is preferably selected electrodeless
Variable speed electric motors, particularly.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
