AI Technical Summary

Problems solved by technology

However, the current loss rate of the wireless charging coil is relatively high, resulting in lower charging efficiency compared with contact charging. At the same time, due to the relatively large volume of the coil, the volume of the speaker cannot be made too small, which affects its portability.

Embodiment Construction

[0031] The specific implementation of the wireless contact charging unit for the modular speaker of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The modular speaker includes the main speaker and several sub-speakers. The main speaker provides audio signals and sends them to the sub-speakers. When in use, the sub-speakers are arranged in different positions of the scene, and receive the audio of different channels sent by the main speaker for playback, realizing on-the-spot Effect. When storing, the main speaker and the sub speaker are fixed together by a fixing mechanism, which is convenient for carrying and storage.

[0033] See attached figure 1 , the main speaker 1 includes a power module 2 arranged inside and a power charging port 3 arranged on the main speaker 1 , the power charging port 3 is connected to the power module 2 to provide a charging function for the power module 2 . The interior of the main ...

Abstract

The invention relates to the technical field of portable sound box power supplies, and discloses a modular sound box wireless contact charging unit. The modular sound box comprises a primary sound boxand multiple secondary sound boxes. The primary sound box and the secondary sound boxes and the secondary sound boxes are respectively connected through a separable fixing mechanism. The primary sound box comprises a power supply module arranged inside and a power supply charging port arranged on the primary sound box. Each secondary sound box comprises a power supply module arranged inside. Thefixing mechanism is arranged on the side of the primary sound box and the secondary sound boxes. A contact charging port is also arranged on the same side of the fixing mechanism. The power supply charging port on the primary sound box is connected with the power supply module of the primary sound box. The contact charging port of the primary sound box is connected with the power supply charging port. The contact charging port of the secondary sound boxes is connected with the power supply module of the secondary sound boxes. Power line charging of the sound box is enabled to be simultaneouslyperformed under the combined state through connection of the wireless contacts.

Description

technical field [0001] The invention relates to the technical field of portable speaker power supplies, in particular to a modular speaker wireless contact charging unit. Background technique [0002] With the development of society and people's increasing entertainment needs, speakers appear in more and more occasions. In recent years, wireless technology and integrated technology represented by Bluetooth have made speakers more and more miniaturized and portable, and are loved by young people. There are two charging methods for portable speakers on the market: power line charging and wireless charging. Cord charging is efficient and easy to use, but it can only charge one speaker at a time. [0003] And existing multi-module sound box, comprises main sound box and a plurality of secondary sound boxes, each sound box all has lithium battery, when a plurality of sound box all will be charged, each sound box all will be equipped with the charging equipment of unit and carry...
