Description

BACKGROUND1. Field of the Invention

[0001] The present invention relates to speakers, especially to a series-connectable column speaker assembly and speaker body thereof.2. Description of the Prior Art(s)

[0002] After the invention of the phonograph, music could be recorded and reproduced, which in turn changed the way people appreciate music. With the advancement of technology, speakers for playing music have become a common feature of daily life. To create different auras for various occasions, speakers come in various forms. For example, box-type speakers allow users to enjoy music at home, wireless speakers allow users to play music anywhere, and columnar speakers are used as music playback devices for weddings, religious events, and other events.

[0003] Taking column speakers as an example, since weddings and religious events are often held in larger spaces or outdoors, conventional column speakers typically include multiple drivers to produce higher decibel levels (dB values), resulting in the conventional column speakers being relatively long. Before the aforementioned event begins, the conventional column speakers must be transported to the event venue by sound control personnel for deployment. Furthermore, these personnel may need to repeatedly move the conventional column speakers while adjusting the sound field at the event venue. However, the length of the conventional column speakers is not convenient for sound control personnel to carry and deploy, and the number of the drivers (sound-producing capacity) of the conventional column speakers is fixed. This means that users cannot flexibly utilize the conventional column speakers to create different sound field effects based on different usage scenarios.SUMMARY OF THE INVENTION

[0004] To overcome the shortcomings, the present invention provides a series-connectable column speaker assembly and a speaker body thereof to mitigate or obviate the aforementioned problems.

[0005] The main objective of the present invention is to provide a series-connectable column speaker assembly and a speaker body thereof that are convenient to be transported and can create different sound field effects based on different usage scenarios.

[0006] The series-connectable column speaker assembly comprises at least two speaker bodies and at least one fixing unit. Each one of the at least two speaker bodies comprises a column cabinet, multiple drivers, and an audio transformer.

[0007] The column cabinet comprises a first side and a second side opposite to each other. The first side comprises a first electrode and a second electrode. The second side comprises multiple first spring pins and multiple second spring pins. The first electrode is electrically connected to the multiple first spring pins, and the second electrode is electrically connected to the multiple second spring pins.

[0008] The multiple drivers are mounted in the column cabinet. The audio transformer is mounted in the column cabinet. The audio transformer is electrically connected to the first electrode, the second electrode, the multiple first spring pins, the multiple second spring pins, and the multiple drivers. The at least one fixing unit is configured to fix the at least two speaker bodies.

[0009] Compared with the column speaker in the prior arts, the series-connectable column speaker assembly of the present invention can connect the at least two speaker bodies in series as user need. For example, when the at least two speaker bodies are transported, the at least two speaker bodies can be separated beforehand. When the at least two speaker bodies are transported to a location (e.g., a wedding venue), the at least two speaker bodies can be fixed through the at least one fixing unit. Two sides of each one of the speaker bodies respectively comprise multiple electrodes (i.e., the first electrode and the second electrode) and multiple spring pins (i.e., the multiple first spring pins and the multiple second spring pins). When the at least two speaker bodies are connected in series, the multiple drivers of the at least two speaker bodies can be electrically connected through the multiple electrodes and the multiple spring pins. That is, the user can connect different numbers of the speaker bodies in series or use one single speaker body of the present invention according to different usage scenarios to create different sound field effects through the different sound-producing capabilities (power performance) of the speaker assembly.

[0010] Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.BRIEF DESCRIPTION OF THE DRAWINGS
