Speaker-Connector Module Sound Routing for Handheld Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices, such as mobile phones, often have multiple mesh-based speaker configurations that compromise their aesthetic appearance while transmitting sound, as the meshes are necessary for sound propagation.
Innovation Solution
A speaker-connector module with a housing featuring a major sound passage connected to a speaker and an electrical connector, where the sound is transmitted through this passage and broadcasted from the connector, reducing the need for multiple sound outlet holes and enhancing sound quality with sound insulation foam and additional sound passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mesh-based speaker configurations are used to transmit sound, then sound transmission function is improved, but the aesthetic appearance of the device deteriorates due to destroyed ornamental appearance
Solution Approach 1:
The patent extracts the sound transmission function from the mesh configuration and relocates it to a dedicated sound passage leading to an earpiece opening. This separates the aesthetic surface (without meshes) from the acoustic function (through the passage), allowing the device body to maintain its ornamental appearance while still providing sound transmission capability through the earpiece.
Solution Approach 2:
The sound passage acts as an intermediary structure that connects the speaker to the earpiece opening without requiring meshes on the device body. This intermediary channel allows sound waves to travel from the speaker through the passage and out through the earpiece, eliminating the need for mesh perforations in the aesthetic housing.
2Reliability
If multiple sound outlet holes are configured to broadcast sound, then sound transmission is improved, but the device appearance is compromised
Solution Approach 1:
The patent merges the sound outlet function with the earpiece opening structure. Instead of having separate sound outlet holes distributed across the device body, the sound passage converges into a single earpiece opening that serves both as an acoustic output and as an integrated component of the device's external interface, thereby maintaining appearance while providing sound broadcast capability.
3Volume of moving object
If speaker and electrical connector are integrated in a compact module, then device miniaturization is improved, but manufacturing complexity increases
Solution Approach 1:
The patent implements nesting by placing the electrical connector within the sound passage structure itself. The connector is positioned inside the housing that contains the sound passage, creating a nested arrangement where one component (connector) is housed within another structure (sound passage housing). This nested configuration enables compact integration of multiple components, reducing overall device thickness while managing manufacturing complexity through a systematic integration approach.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration minimizes the number of sound outlet holes, maintains the device's appearance, and improves sound quality by concentrating sound output, while also facilitating miniaturization through reduced thickness and enhanced sound propagation.
Implementation Method 1
the sound generated by the speaker may be transmitted through the major sound passage and broadcasted from the electrical connector
