Description

Technical Field

[0001] The utility model relates to the technical field of micro speakers, and particularly relates to a power terminal of a micro speaker. Background Art

[0002] A micro speaker is a miniaturized electronic component commonly found in products such as mobile devices, headphones, and audio systems. It can convert electrical signals into air vibrations to produce sound. Micro speakers typically have dimensions with a diameter less than 20 mm and a height less than 10 mm. Due to their small size, low power consumption, and good sound quality, they are widely used in various fields. A micro speaker mainly consists of a diaphragm, a magnet, wires, etc. After receiving an external electrical signal, the diaphragm therein is vibrated by the action of a magnetic field to generate sound. The power terminal is a main component of the micro speaker. However, the power terminal of the micro speaker in the prior art cannot be effectively extended during use, so it does not have a telescopic function, which makes it unable to adapt to connections and installations at different positions, reducing its scope of application and installation efficiency. Therefore, we propose a power terminal of a micro speaker. Content of the Utility Model

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a power terminal of a micro speaker, which can be effectively extended, so that it has a telescopic function, thereby enabling it to adapt to connections and installations at different positions, and improving its scope of application and installation efficiency.

[0004] To achieve the above purpose, a power terminal of a micro speaker is provided, including: a terminal body, a plug-in end is arranged above the terminal body, and a wiring end is arranged below the terminal body. A connecting protrusion is arranged on the front side of the wiring end, and a connecting groove is arranged on the top of the connecting protrusion.

[0005] According to the power terminal of the micro speaker, a connecting groove is opened on the front side of the wiring end. A docking post is connected to the rear inner wall of the connecting groove, and a moving tube is sleeved outside the docking post. The front end of the moving tube is connected to the rear wall of the connecting protrusion.

[0006] According to the power terminal of the micro speaker, the wiring end is arranged in an L shape, and a wiring hole is arranged on the wiring end.

[0007] According to the power terminal of the micro speaker, a plug-in hole is arranged on the plug-in end.

[0008] According to the power terminal of the micro speaker, the inner wall of the moving tube fits on the outer wall of the docking post, and the outer wall of the moving tube fits on the inner wall of the connecting groove.

[0009] According to the described micro speaker power terminal, docking blocks are connected to the top and bottom near the left side of the inner cavity of the moving tube, and docking grooves matching the docking blocks are provided on the outer wall of the docking column.

[0010] According to the described micro speaker power terminal, an installation groove is provided near the right side of the top of the wiring terminal, and a fastening screw is arranged in the installation groove. Threaded holes matching the fastening screw are provided at the bottom of the inner cavity of the installation groove, the top and bottom of the moving tube, and the bottom of the inner cavity of the connection groove.

[0011] The above solution has at least one of the following beneficial effects: Through the mutual cooperation among components such as the docking column, the moving tube, the docking block, and the docking groove, the present technical solution can be effectively extended, enabling it to have a telescopic function, so that it can adapt to connections and installations at different positions, improving its scope of application and installation efficiency.

[0023] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be construed as a limitation on the protection scope of the present invention.

[0024] Referring to Figures 1 to 7 , in an embodiment of the present invention, a micro speaker power terminal includes a terminal body 1. An insertion end 2 is provided above the terminal body 1. An insertion hole 7 is provided on the insertion end 2. And a wiring end 3 is provided below the terminal body 1. A connection protrusion 5 is provided on the front side of the wiring end 3. And a connection groove 6 is provided on the top of the connection protrusion 5.

[0025] A connection groove 8 is opened on the front side of the wiring end 3. A docking post 9 is connected to the rear inner wall of the connection groove 8. And a moving tube 10 is sleeved outside the docking post 9. The inner wall of the moving tube 10 is attached to the outer wall of the docking post 9. And the outer wall of the moving tube 10 is attached to the inner wall of the connection groove 8. The front end of the moving tube 10 is connected to the rear wall of the connection protrusion 5.
