Description

Micro landscape desktop sound equipment

Technical Field

The invention relates to the field of computer output equipment, in particular to a computer sound box.

Background

Computer desktop audio is a common external device of a computer, and generally comprises a power amplifier and a sound box; in order to meet the increasing interest requirements of users, some current computer sound equipment comprises an internal miniature landscape; typically, for example, a fountain sound mainly comprises a sound box base body and a landscape box body constructed on the sound box base body, wherein the landscape box body is a closed transparent box body, a water body is stored at the bottom of the landscape box body, and the landscape box body is provided with a nozzle and a water pump; the driving current of the water pump is coupled with the audio current of the sound equipment; thus, the driving current of the water pump is continuously changed along with the music; in the process, the driving force of the water pump to the water body is continuously changed, so that the water column sprayed upwards from the nozzle is continuously changed.

However, in the actual use process, due to the inertia of the rotor of the water pump motor, the rotating speed of the water pump has time lag for the change of the water pump driving current; the water body also has larger inertia, and the motion of the water body has time lag relative to the change of the rotating speed of the water pump; this results in the water column ejected by the nozzle having a poor performance on music; the usual reaction is that when the volume is low, the water column is kept at a low level, and when the volume is increased to a certain level, the height of the water column suddenly rises and is kept at a high level; it is extremely difficult to make the water column follow the music to make an elegant fluctuation.

Disclosure of Invention

In view of the above problems, it is an object of the present invention to provide a micro landscape table top stereo which can form a fountain landscape and make the fountain water column follow the continuous fluctuation of music accurately to improve the artistic expression.

The technical scheme adopted by the invention for solving the technical problems is as follows: the micro landscape desktop sound box comprises a power amplifier and a sound box; the sound box comprises a sound box base body and a landscape box body constructed on the sound box base body; the landscape box body is enclosed by a transparent shell, a water body is stored at the bottom of the landscape box body, and the landscape box body is provided with a nozzle and a driving water pump; the water inlet end of the driving water pump is positioned below the water body, and the water outlet end of the driving water pump is communicated to the nozzles through the diversion pipes; when detecting audio current, the driving water pump operates at constant power; the nozzle is composed of rubber pipes which extend vertically upwards, and a section of silicon steel short pipe is sleeved at the upper end of each rubber pipe; the nozzles are uniformly distributed in the circumferential direction of the axis of the landscape box body, an electromagnetic cylinder is vertically arranged at the axis of the bottom of the landscape box body, and a magnet exciting coil of the electromagnetic cylinder is coupled with the audio current of the sound box base body through an amplifying module; the upper side of the nozzle is horizontally provided with a blocking plate, and the surface of the blocking plate is densely covered with vertical fine holes.

Preferably, the input end of the driving water pump is coupled to the audio current through a positive feedback amplification module, that is, the input or output audio current of the sound box base body is used as the input current of the positive feedback amplification module, and the positive feedback amplification module is enabled to always work in a saturated output state through a positive feedback amplification mechanism.

Preferably, the outer sides of the silicon steel short pipes at the upper end of each nozzle are respectively provided with one same induction coil; the induction coils corresponding to different nozzles are connected to different frequency band output ends of one frequency division module; the input end of the frequency division module is electrically connected with the amplifying module after being connected with the electromagnetic cylinder in parallel.

Preferably, an oscillating coil is respectively wound on the outer side of the silicon steel short pipe at the upper end of each nozzle, and the oscillating coil and an oscillating capacitor form an LC oscillating module; the resonance frequencies of the LC oscillation modules corresponding to the nozzles are different; the excitation coil of the electromagnetic cylinder is coupled with a transmitting antenna; and a conductive layer is plated on the inner wall of the space between the blocking plate and the bottom of the landscape box body so as to shield the electromagnetic wave of the transmitting antenna.

The invention has the beneficial effects that: when the micro landscape desktop sound works, the exciting current of the electromagnetic cylinder fluctuates along with the audio current, so that the magnetic attraction of the electromagnetic cylinder to the silicon steel short pipes at the upper ends of the nozzles fluctuates along with music, and a continuously fluctuating inclination angle is formed between the axis of each nozzle and the vertical direction; the blocking plate is arranged above each nozzle, and the vertical fine holes are densely distributed on the surface of the blocking plate, so that the horizontal component of the water column sprayed upwards from the nozzles is blocked by the blocking plate, and therefore, when the inclination angle between the nozzles and the vertical direction continuously fluctuates, namely the nozzles continuously swing along with music, the water column sprayed from the nozzles can continuously fluctuate through the vertical component of the blocking plate, and further the height of the water column above the blocking plate continuously changes along with the music; in the process, components with larger inertia, such as a motor rotor and a water body, are not involved; the transverse component of the water column changes obviously only by the upper end of the nozzle moving transversely to a smaller position, so that the water column above the baffle plate can accurately follow the fluctuation of the music continuity.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the first embodiment is as follows:

in the first embodiment shown in fig. 1 and fig. 2, the micro landscape desktop sound equipment includes a power amplifier (not shown) and a sound box; the sound box comprises a sound box base body 1 and a landscape box body 2 constructed on the sound box base body 1; the landscape box body 2 is enclosed by a transparent shell, a water body is stored at the bottom, and the landscape box body is provided with a nozzle 21 and a driving water pump 22; the water inlet end of the driving water pump 22 is positioned below the water body, and the water outlet end of the driving water pump is communicated to the nozzles 21 through the diversion pipes; the driving water pump 22 operates at constant power when detecting audio current; specifically, the input end of the driving water pump 22 may be coupled to the audio current through a positive feedback amplification module, so that the input or output audio current of the sound box base 1 is used as the input current of the positive feedback amplification module, and the positive feedback amplification module is always operated in a saturated output state through a positive feedback amplification mechanism.

In the micro-landscape computer sound, the nozzle 21 is composed of rubber pipes extending vertically upwards, and a section of silicon steel short pipe 23 is sleeved at the upper end of each rubber pipe; the nozzles 21 are uniformly distributed in the circumferential direction of the axis of the landscape box body 2, an electromagnetic cylinder 24 is vertically arranged at the axis of the bottom of the landscape box body 2, and an excitation coil of the electromagnetic cylinder 24 is coupled with the audio current of the sound box base body 1 through an amplification module; the upper side of the nozzle 21 is horizontally provided with a blocking plate 25, and the surface of the blocking plate 25 is densely distributed with vertical pores.

When the micro landscape desktop sound works, the exciting current of the electromagnetic cylinder 24 fluctuates along with the audio current, so that the magnetic attraction of the electromagnetic cylinder 24 on the silicon steel short pipes 23 at the upper ends of the nozzles 21 fluctuates along with music, and a continuously fluctuating inclination angle is formed between the axis of each nozzle 21 and the vertical direction; since the blocking plate 25 is arranged above each nozzle 21, the surface of the blocking plate 25 is densely covered with vertical fine holes, which causes the horizontal component of the water column sprayed upwards from the nozzle 21 to be blocked by the blocking plate 25, so that when the inclination angle between the nozzle 21 and the vertical direction continuously fluctuates, that is, the nozzle 21 continuously swings along with the music, the water column sprayed from the nozzle 21 can continuously fluctuate through the vertical component of the blocking plate 25, and further the height of the water column above the blocking plate 25 continuously changes along with the music; in the process, components with larger inertia, such as a motor rotor and a water body (the height of a water column is not changed in a mode of adjusting the thrust of the water body) are not involved; the transverse component of the water column changes significantly only by the upper end of the nozzle 21 moving across a small distance, so that the water column above the baffle 25 can follow the continuous fluctuation of music accurately.

Example two:

for the second embodiment shown in fig. 2 and 3, the same induction coil 26 is respectively arranged outside the silicon steel short pipe 23 at the upper end of each nozzle 21; the induction coils 26 corresponding to different nozzles 21 are connected to different frequency band output ends of a frequency dividing module (not shown); the input end of the frequency division module is electrically connected with the amplification module after being connected with the electromagnetic cylinder (24) in parallel.

According to the second embodiment, as for the music in play, the frequency contained therein is different, so is the nozzle 21 responding to the music; for example, when the current music contains more low frequency components, the nozzle connected to the low frequency output end of the frequency dividing module is more sensitive to the response of the music fluctuation, and when the current music contains more high frequency components, the nozzle connected to the high frequency output end of the frequency dividing module is more sensitive to the response of the music fluctuation; that is, the water column in the landscape box body 2 not only can follow the fluctuation of the volume of the music, but also responds to the frequency spectrum characteristics of the music; further improving the artistic expressive force.

Example three:

for the third embodiment shown in fig. 4, unlike the first embodiment, an oscillating coil is wound around the outer side of the short silicon steel tube 23 at the upper end of each nozzle 21, and the oscillating coil and an oscillating capacitor form an LC oscillating module (not labeled); the resonance frequencies of the LC oscillating modules corresponding to the nozzles 21 are different; the excitation coil of the electromagnetic cylinder 24 is coupled to a transmitting antenna 27; the inner wall of the space between the baffle plate 25 and the bottom of the landscape box body 2 is plated with a conductive layer to shield the electromagnetic wave of the transmitting antenna 27. Thus, it is also possible to vary the oscillatory response of different nozzles 21 to different music so that the water column in the landscape box 2 responds to the spectral characteristics of the music. Compared with the second embodiment, the oscillating coils in the third embodiment do not need to be connected to the distribution module through wires, and the circuits in the landscape box 2 can be simplified.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
