Landscape electronic speaker

Abstract

The invention provides a landscape type electronic sound box, comprising a base, a transparent sealing frame is arranged on the top of the base, the bottom of the sealing frame is closed by a layer of elastic film, and the lower side of the elastic film is supported by Supported by a screen; inside the sealing frame and above the elastic film, there is a barrier plate, and fountain holes are evenly distributed on the barrier plate, and the fountain holes form nozzles upward; liquid is sealed in the sealing frame In the non-working state, the liquid level of the liquid just submerges the nozzle; a section of hollow cylinder is formed between the support mesh plate and the base; a sound hole is opened under the side of the hollow cylinder; and The bottom of the hollow cylinder is provided with a top speaker facing the supporting grid; the top speaker is electrically coupled to the power amplifier module in the base. There is a music fountain in the speaker, and the ups and downs of the fountain torrent and the music have good synchronization and linear correlation.

Description

technical field [0001] The invention relates to the field of electronic sound boxes, in particular to a landscape sound box with a musical fountain. Background technique [0002] With the improvement of the quality of life and the demand for fun, the ornamental quality of desktop electronic equipment is also more and more exquisite; at present, there is a landscape speaker with a musical fountain, and the structure of the musical fountain mainly includes a transparent sealing frame. Liquid is sealed in the sealed frame, and as the music fluctuates, the liquid forms a fluctuating music fountain in the sealed frame. The current landscape speaker with a fountain is driven by a motor to drive the water pump. A serious problem is that when the audio current is applied to the water pump and the water pump drives the torrent, due to the internal pressure of the water pump The effect is a slow corresponding process, so there is a very obvious delay phenomenon; in addition, because ...

Problems solved by technology

The current landscape speaker with a fountain is driven by a motor to drive the water pump. A serious problem is that when the audio current is applied to the water pump and the water pump drives the torrent, due to the internal pressure of the water pump The effect is a slow corresponding process, so there is a very obvious delay phenomenon; in addition, because the motor speed and current are in a non-linear relationship when the current is small, this leads to a non-proportional relationship between the height and volume of the fountain torrent. The performance of the situation is that when the volume is low, the torrent of the fountain hardly appears, and when the volume is slightly higher, the height of the torrent of the fountain increases rapidly, and soon hits the top of the sealed frame, making it difficult to express the ups and downs of the music
