Description

Technical Field

[0002] In the field of audio equipment, the tweeter diaphragm is a key component of a loudspeaker system, and its performance and quality directly affect the sound quality and lifespan of the entire loudspeaker. However, inaccurate positioning and low assembly efficiency have always been problems that need to be solved in the traditional tweeter diaphragm installation process. Traditional tweeter diaphragm installation usually relies on manual alignment and fixing, which not only requires operators to have a high level of skill, but also makes it difficult to ensure that the positioning is accurate every time. Due to inaccurate positioning, the tweeter diaphragm may be subjected to unnecessary stress during installation, thereby affecting its sound quality and lifespan. At the same time, manual alignment and fixing also reduces assembly efficiency and increases production costs and time. In addition, traditional tweeter diaphragm devices often use a fixed connection method, which is difficult to disassemble and maintain once installed. This brings great inconvenience to operators when it is necessary to replace or repair the tweeter diaphragm. Moreover, traditional devices also have shortcomings in terms of sound quality and structural stability, making it difficult to meet the pursuit of high sound quality and structural stability requirements of modern audio equipment. In order to solve the above problems, we propose a tweeter diaphragm that can be precisely positioned and installed. Utility Model Content

[0044] Instructions for use

[0045] The bottom end of the mounting ring 1 is provided with a circular groove, and a connecting sleeve 7 is fixedly installed, which provides an accurate positioning point for the connection between the mounting ring 1 and the washer 3. The top end of the washer 3 is provided with a connecting base 8 in the groove, which cooperates with the connecting sleeve 7 to ensure easy alignment during assembly. When the fixing block 12 at the top end of the connecting base 8 enters the connecting sleeve 7, the conical surface of the fixing block 12 comes into contact with the latch 14 in the connecting sleeve 7 due to the flat-topped conical design of the fixing block 12. The conical surface of the fixing block 12 acts on the latch 14, pushing it outward and compressing the return spring 15. When the fixing block 12 is completely inserted into the connecting sleeve 7, the latch 14 is reset under the action of the return spring 15 and moves to the bottom end of the fixing block 12, completing the clamping. At this time, the connecting base 8 and the connecting sleeve 7 are connected together. When disassembly is required, first move the connecting sleeve 7 downward. At this time, the multiple latches 14 start to move downward after passing through the sliding block 13. When the multiple latches 14 move to the bottom end of the sliding block 13, the latches 14 will support the bottom end of the sliding block 13 under the action of the return spring 15. Then move the connecting sleeve 7 upward. The supporting force of the latches 14 allows the sliding block 13 and the connecting sleeve 7 to move upward together. When the top end of the sliding block 13 merges with the bottom end of the fixing block 12, the multiple latches 14 are again moved outward by the conical surface of the fixing block 12 or the sliding block 13. The movement of the latches 14 releases the clamping between the connecting sleeve 7 and the connecting base 8, allowing the connecting sleeve 7 to be pulled out of the connecting base 8, completing the disassembly process.
