Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a stacked combined speaker. Background Art

[0002] A speaker is an electronic device used to amplify and reproduce sound. It usually consists of a speaker (commonly known as a horn), a crossover, and a cabinet, etc. The main function of the speaker is to convert an audio signal into sound waves, and then transmit them to the human ear through the air so that we can hear the sound. In addition, with the development of technology, the design and functions of speakers have become increasingly diversified. For example, new products such as wireless speakers and smart speakers have emerged. Smart speakers not only have the functions of traditional speakers, but also integrate intelligent voice assistants, and can realize functions such as human-computer interaction and smart home control.

[0003] The patent document with the application number CN201822157457.X discloses a stacked combined speaker, which includes two or more speaker units stacked in sequence from bottom to top; the bottom of the housing has a positioning groove, and the top of the housing has a corresponding positioning convex part; the front side of the housing is provided with a sound outlet hole; the rear side of the housing is provided with upper and lower electrical interfaces, and the upper and lower electrical interfaces are electrically connected inside the housing; the upper speaker unit is stacked on the adjacent lower speaker unit, and the positioning groove at the bottom of the upper speaker unit is adapted to the positioning convex part at the top of the lower speaker unit; the lower electrical interface of the upper speaker unit is pluggable and connected to the upper electrical interface of the lower speaker unit through a patch cord; thus, two or more speaker units are stacked up and down to form a columnar speaker, obtaining a volume superposition effect, and stacking vertically brings a better experience effect to consumers; in particular, its structure is simple, the combination is very convenient, and the electrical connection is also convenient and fast. Based on the retrieval of the above patent and the combination of the combined speakers in the prior art, it is found that when the combined speakers are applied, stacking multiple cabinets together has certain risks. Especially when the speakers are working, the sound amplification vibration will cause the stacked speakers to shift. In severe cases, the combined speakers will spread out or even fall, which not only poses a safety risk, but also damages the speakers. In addition, when stacking the speakers, mechanical assistance is required for stacking, which is time-consuming and laborious. Summary of the Utility Model
