Receiving antenna for wireless mini loudspeaker box

Abstract

The invention provides a receiving antenna for a wireless mini loudspeaker box, and relates to the technical field of loudspeaker boxes. The equipment comprises a sound box body and a limiting device, a protective cover is clamped on the surface of the sound box body; the inner wall of the sound box body is fixedly connected with four clamping rods; the surfaces of the four clamping rods are slidably connected with a circuit board. A cover plate is clamped on one side, far away from the protective cover, of the loudspeaker box body; a limiting device is arranged on the inner wall of the sound box body; the limiting device comprises two telescopic rods; the two telescopic rods are fixedly connected with the inner wall of the sound box body. The invention solves the problems that: since the connection between an existing sound box and a circuit board is realized through a plurality of clamping rods on the sound box and holes in the circuit board, and the adaptability of the connection between the clamping rods and the holes in the circuit board is relatively high, a worker cannot conveniently clamp the clamping holes in the circuit board into the clamping rods to limit the center of the circuit board; and therefore, the working difficulty of mounting the circuit board by a worker is increased, and the working efficiency of the worker is reduced.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a receiving antenna for a wireless mini sound box. Background technique [0002] In a broad sense, a speaker refers to a device that uses electronic circuit design to convert audio and electronic signals. However, in general spoken language, a speaker usually refers to a complete set of equipment that can restore and play audio signals. Speaker equipment probably includes power amplifiers and peripheral equipment. (including compressors, effectors, equalizers, VCD, DVD, etc.), speakers (speakers, speakers), mixers, etc., the development history of speaker technology can be divided into four parts: tubes, transistors, integrated circuits, and field effect tubes. stage.

Problems solved by technology

[0003] With the development of science and technology, the size of the speaker is gradually reduced, and the bluetooth speaker gradually enters people's field of vision. The way of receiving signals on the bluetooth speaker is usually to use the chip on the circuit board to receive the signal, so as to achieve the connection between the speaker and the mobile phone. The connection between the existing speaker and the circuit board is connected to the hole on the circuit board through several clamping rods on the speaker, due to the adaptability of the connection between the clamping rod and the hole on the circuit board Higher, which makes it inconvenient for the staff to clamp the card holes on the circuit board into the card rod to limit the entry of the circuit board, thus increasing the difficulty of the staff to install the circuit board and reducing the work efficiency of the staff
