Desktop fountain landscape sound box

Abstract

The invention provides a desktop fountain landscape sound box comprising a power amplifier and a sound box, wherein the sound box comprises a sound box substrate and a landscape box body; the landscape box is surrounded by a transparent casing, a water body is stored at the bottom, and the landscape box is provided with spray nozzles and a driving water pump; a water inlet end of the driving water pump is positioned below a water body, and a water outlet end is communicated to each spray nozzle through a flow dividing pipe; the driving water pump runs at a constant power when an acoustic frequency current is detected; each spray nozzle comprises a short rubber tube and a control component surrounding the short rubber tube; the control component comprises two tile-shaped silicon steel sheets laminated to the outer wall of the short rubber tube, and an electromagnetic tube surrounding the short rubber tube and the tile-shaped silicon steel sheets; and the electromagnetic tube comprises a base tube and an excitation coil wound outside the base tube, and the excitation coil is coupled to the acoustic frequency current of the sound box substrate through an amplification module. The fountain landscape sound box can form a fountain landscape, and can enable fountain water columns to continuously rise and fall with music, so as to improve the artistic expressive force.

Description

technical field [0001] The present invention relates to the field of electronic music equipment, in particular, to a desktop speaker. Background technique [0002] Desktop speakers are a common computer peripheral equipment, usually including power amplifiers and speakers; in order to meet the increasing taste requirements of users, some current desktop speakers include internal landscapes; typical, such as fountain speakers, mainly include speaker bases, And the landscape box built on the base of the speaker, the landscape box is a closed transparent box, with a water body at the bottom, and a nozzle and a water pump are arranged; the driving current of the water pump is coupled to the audio current of the speaker; thus, the driving current of the water pump The current changes continuously with the music; during this process, the driving force of the water pump to the water body changes continuously, so that the water column sprayed upward from the nozzle changes continu...

Problems solved by technology

[0003] However, in the actual use process, due to the inertia of the water pump motor rotor, the speed of the water pump has a time lag for the change of the driving current of the water pump; and the water body itself has a large inertia, and the movement of the water body relative to the change of the speed of the water pump also exists Time lag; this results in a poor performance of the water column sprayed by the nozzle for music; the usual response is that when the volume is low, the water column remains at a low level, and when the volume increases to a certain level, The height of the water column suddenly skyrocketed and remained at a high level; it was extremely difficult to make the water column rise and fall gracefully to the music
