Speaker Side Wall Circuit Board Mounting for Compact Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing speaker designs require a larger mounting space due to the placement of pads in the Z-axis direction, which limits the size of smaller products and modules, necessitating a new connection method to accommodate a Flexible Printed Circuit Board (FPCB).
Innovation Solution
A speaker design featuring electrical connection members with second pad portions exposed from the side wall of the housing, allowing the FPCB to be attached and connected, reducing the need for extensive mounting space and improving compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If pads are disposed in the Z-axis direction on the housing, then electrical connection is achieved, but mounting space increases
Solution Approach 1:
The patent changes the pad arrangement from the Z-axis direction (vertical) to the X-axis direction (horizontal side wall). This dimensional transition allows the FPCB to be mounted horizontally along the side wall rather than requiring vertical space, thereby reducing the overall mounting footprint while maintaining electrical connection functionality.
2Volume of moving object
If pads are disposed in the Z-axis direction, then electrical connection is established, but module size increases
Solution Approach 1:
By relocating pads from the vertical Z-axis to the horizontal X-axis side wall, the patent enables a more compact module volume. The FPCB connects horizontally along the side wall, reducing the vertical height requirement and overall module size while maintaining reliable electrical connection through the same pad-FPCB connection mechanism.
3Object-affected harmful factors
If circuit board is mounted on the housing top surface, then electrical connection is achieved, but interference with terminal antenna occurs
Solution Approach 1:
The patent extracts the circuit board mounting location from the housing top surface (where it would interfere with the terminal antenna) and relocates it to the side wall. This spatial separation removes the harmful interference effect while the circuit board layout remains relatively simple, connecting to pads on the side wall rather than requiring complex routing around the antenna area.

AI summary
The present invention relates to a speaker, and speaker module. The speaker comprises a housing and two electrical connection members mounted on the housing, each electrical connection member comprises a second pad portion exposed from a side wall of the housing, and the second pad portion is disposed in parallel to the side wall of the housing. The speaker further comprises a circuit board attached to the side wall of the housing, and the circuit board is electrically connected to the second pad portions. The speaker of the present invention enables attaching the circuit board to the side wall of the housing, thus increasing operation space, and reducing operational risks. By attaching the circuit board to the side wall of the housing, the present invention reduces interference of the circuit board on a terminal antenna, and reduces the possibility of the circuit board involving in vibration of a back chamber, thus improving the performance of the speaker. Meanwhile, by providing the circuit board on the side wall of the housing, the present invention simplifies the shape of the circuit board, thus providing a compact layout, and accordingly saving costs.
