[0001] This utility model relates to the field of electroacoustic device technology, and in particular to a loudspeaker and its terminal block. Background Technology

[0002] A terminal block is the interface connecting a speaker to audio equipment, responsible for transmitting electrical signals to drive the speaker to produce sound. Existing speaker terminal blocks typically include a mounting plate assembled onto the outer surface of the speaker body and a wiring board fixed to the outer side of the mounting plate. The wiring board has through holes that pass through the mounting plate, allowing wires from the speaker body to pass through and connect.

[0003] The existing nylon wire is directly soldered to the surface of the terminal block. When soldering the nylon wire, the molten solder tends to flow on the terminal block and cannot properly wrap the nylon wire, making the connection between the nylon wire and the terminal block unstable and prone to open circuits. Utility Model Content

[0004] Therefore, it is necessary to provide a speaker terminal block.

[0005] Therefore, it is necessary to provide a loudspeaker.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A terminal block for a loudspeaker includes a mounting plate assembled on the outer surface of the loudspeaker body and a terminal block fixed to the outer side of the mounting plate. The terminal block has a wire-passing hole that passes through the mounting plate. The wire-passing hole is used for the connection of the nylon wire led out from the loudspeaker body. The terminal block also includes a wire-holding plate formed by bending and extending on the side of the terminal block or mounting plate adjacent to the wire-passing hole. The wire-holding plate has a slot. One of the slot sidewalls on the inner and outer sides of the slot is provided with an elastic pressing arm. The outer end of the nylon wire is inserted into the slot and is abutted and positioned by the elastic pressing arm.

[0007] Furthermore, the wire clamping plate has a through hole at the position opposite to the elastic pressure arm.

[0008] Furthermore, the slot has an opening that communicates with one side of the elastic pressure arm.

[0009] Furthermore, the side of the elastic pressing arm near the opening is also turned outward to form a folded edge.

[0010] Furthermore, the opening is formed above the elastic pressure arm.

[0011] Furthermore, the wire clamping plate is located on one side of the terminal block, and the wire clamping plate and the terminal block are integrally formed.

[0012] Furthermore, a transition arc is provided at the connection between the wire clamping plate and the connector plate.

[0013] Furthermore, the periphery of the wire hole is rounded.
