Micro landscape desktop audio

Abstract

The invention provides a micro landscape desktop audio comprising a power amplifier and a sound box, wherein the sound box comprises a sound box matrix and a landscape box 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 spray nozzles and a driving water pump; a water inlet end of the driving water pump is located below the water body, and a water outlet end of the driving water pump is connected to the spray nozzles through shunt pipes; the driving water pump runs at constant power when detecting audio current; each spray nozzle is composed of a vertically upward extending rubber pipe, and a segment of short silicon steel pipe is sleeved on an upper end of each rubber pipe; the spray nozzles are uniformly distributed along the conferential direction of the axial line of the landscape box body, and an electromagnetic column body is vertically arranged at the axial line of the bottom of the landscape box body, and a magnet exciting coil of the electromagnetic column body is coupled to the audio current of the sound box matrix through an amplifying module; and a blocking plate is horizontally arranged on the upper side of the spray nozzle, and vertical pores are densely distributed on the surface of the blocking plate. The desktop audio can form a fountain landscape, and the fountain water columns accurately ascend and descend with the music so as to improve the artistic expression.

Description

technical field [0001] The invention relates to the field of computer output devices, in particular, to a computer audio system. Background technique [0002] Computer desktop audio is a common computer peripheral device, usually including power amplifiers and speakers; in order to meet the increasing taste requirements of users, some current computer audio includes internal miniature landscapes; typical, such as fountain audio, which mainly includes speakers The substrate, and the landscape box built on the speaker substrate, the landscape box is a closed transparent box with water stored at the bottom, and is equipped with a nozzle and a water pump; the driving current of the water pump is coupled to the audio current of the sound; thus, the water pump The driving current of the pump changes continuously with the music; during this process, the driving force of the water pump on the water body changes continuously, so that the water column sprayed upward from the nozzle ch...

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
