Speaker Terminal Component Wire Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional speaker designs face issues with structural compactness and stability due to interference between terminal plates and magnets, and the use of soldering for electrical connections leads to inconvenience and potential damage to plastic support pieces, especially when changing or dismounting tweeters.
Innovation Solution
A terminal component comprising two terminals, a sleeve seat, and fixing heads, with wire guiding slots and a heat dissipation chamber, allowing for secure wire connection without soldering, reducing the external size and improving structural stability and compactness by using a standard plug connection method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal plate is riveted to the support piece to prevent interference with the magnet, then the external diameter of the housing increases, but the overall size of the speaker becomes larger
Solution Approach 1:
The patent extracts the terminal plate from the traditional support piece structure. Instead of riveting a terminal plate to a plastic support piece, the invention uses a separate metal support piece that integrates both support and terminal functions, eliminating the need for a terminal plate and reducing the housing external diameter.
Solution Approach 2:
The patent merges the support function and terminal function into a single metal support piece. The support piece simultaneously provides mechanical support for the voice coil and serves as the electrical terminal, combining two previously separate components into one.
2Length of stationary object
If the support piece is made thin to reduce the overall height of the voice coil, then the height decreases, but the support piece becomes prone to distortion when subjected to welding temperatures
Solution Approach 1:
The patent changes the material parameter of the support piece from plastic to metal. This material parameter change enables the support piece to withstand high welding temperatures (430°C) without distortion, while still maintaining a thin profile to reduce voice coil height.
3Reliability
If soldering is used to connect the signal line to the terminal plate, then electrical connection is achieved, but dismounting and changing the tweeter becomes inconvenient and the plastic support piece may be burnt and distorted
Solution Approach 1:
The patent segments the electrical connection system into a detachable connector interface. The signal line connects to the terminal via a plug-and-socket mechanism that can be easily disconnected and reconnected, separating the electrical connection function from permanent bonding.
Solution Approach 2:
The patent introduces a connector as an intermediary component between the signal line and the terminal. This connector serves as a mediator that enables easy connection and disconnection without directly welding to the plastic support piece, avoiding heat damage.
4Reliability
If an interconnection component is used to connect the terminal plate to the signal line, then electrical connection is achieved, but mounting and changing the tweeter becomes inconvenient and the plastic support piece is easy to break
Solution Approach 1:
The patent changes the material parameter of the support piece from plastic to metal, dramatically increasing its mechanical strength. This enables the support piece to withstand the forces required for mounting and changing tweeters without breaking.

AI summary
A terminal component is applied to a speaker, and includes two terminals, a sleeve seat, and two fixing heads. Each terminal includes a terminal head and a terminal body. The sleeve seat includes two terminal blocks. The two terminal blocks respectively accommodate the two terminal bodies, so that the two terminal heads are exposed outside the sleeve seat. The two fixing heads are respectively combined with the two terminal heads, to respectively fasten two wires to the two terminals.
