Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker modules face difficulties in smoothly transmitting high-frequency sound outputs due to misalignment with the speaker holes in electronic devices, making it challenging to mount the speaker module without altering the arrangement of other components.
Innovation Solution
A speaker module design featuring an inclined diaphragm that aligns with the speaker hole, comprising a yoke, magnet, frame, voice coil, and protection member, where the diaphragm is connected to the frame in a way that it is non-perpendicular to the outer side surface, ensuring optimal sound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the speaker module is mounted with a perpendicular diaphragm to the frame, then the structure is simple and easy to manufacture, but the high-frequency sound transmission is blocked due to misalignment with the speaker hole
Solution Approach 1:
The diaphragm is designed to be inclined relative to the frame, creating an asymmetric structure that aligns the sound transmission direction with the speaker hole. This asymmetric configuration enables high-frequency sound to pass through smoothly while maintaining a relatively simple overall structure.
Solution Approach 2:
The solution transitions from a two-dimensional perpendicular arrangement to a three-dimensional inclined arrangement. By introducing an inclination angle, the diaphragm aligns with the speaker hole in the vertical dimension, enabling proper sound transmission without complex lateral adjustments.
2Reliability
If the speaker module is slantly mounted to align the sound hole, then the high-frequency sound transmission is improved, but it becomes difficult to mount without changing the arrangement of other components
Solution Approach 1:
Instead of slantly mounting the entire speaker module (which would require changing component arrangements), the asymmetry is introduced only in the diaphragm's orientation relative to the frame. This allows the module to be mounted in a standard perpendicular position while still achieving proper sound transmission alignment.
Solution Approach 2:
The inclination function is segmented from the overall module mounting orientation. The frame and diaphragm are designed as separate components with a fixed inclination relationship, allowing the module to be mounted perpendicular to the device surface while the diaphragm itself maintains the required inclination for sound transmission.
3Device complexity
If the diaphragm is made perpendicular to the frame, then the assembly is simple, but the high-frequency band output is reduced due to misalignment with the speaker hole
Solution Approach 1:
The diaphragm is designed with an asymmetric inclination relative to the frame, creating a non-perpendicular configuration that aligns the sound transmission path with the speaker hole. This asymmetric design improves high-frequency output while maintaining relatively simple assembly procedures.

Function Achieved in This Case
The inclined diaphragm configuration ensures smooth transmission of high-frequency sound outputs, enhancing sound quality and ease of mounting without disrupting other device components.
Implementation Method 1
The voice coil is mounted around the magnet and vibrates the vibration plate by an interaction between the magnet and an electric signal which is applied from the wire

AI summary
A speaker module including an inclined diaphragm and to an electronic device is provided. The speaker module includes the speaker module, the speaker module including a yoke configuring one surface of the speaker module, a magnet including one surface arranged on an inner surface of the yoke, a frame configuring a side surface of the speaker module and including a first end portion connected to the yoke, a voice coil spaced apart from the magnet and including at least a portion overlapping the magnet, and a diaphragm comprising an inner surface on which the voice coil is arranged. The diaphragm is connected to a second end portion opposite to the first end portion of the frame and is inclined to be non-perpendicular to an outer surface of the frame, so that a sound in a high-frequency band output through the speaker module can be smoothly transmitted outside the electronic device.
