Solution Overview

Problem

Portable electronic devices with improperly configured sound boxes and speaker locations suffer from unnatural audio due to loss of spatial sound characteristics and compromised antenna signal reception.

Innovation Solution

A portable electronic apparatus design featuring a sound member with a sound outlet, a circuit board with a through hole corresponding to the sound outlet, and a frame with a matching through hole, where the circuit board is positioned between the structural member and the frame, allowing sounds to exit while minimizing interference with antennas by not being between the sound member and the back cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the circuit board is disposed between the sound member and the back cover, then the device structure is simplified, but the antenna signal reception is deteriorated

Engineering Contradiction:
Improvedevice structureVSAvoidantenna signal reception
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the device into distinct functional zones by positioning the circuit board in a specific location (between the structural member and frame, not between sound member and back cover). This segmentation allows the antenna on the back cover to operate independently without interference from the circuit board, while still maintaining a simplified overall structure.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the speakers are improperly configured, then the device can be compact, but the spatial sound characteristics are lost

Engineering Contradiction:
Improvedevice compactnessVSAvoidspatial sound characteristics
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating a dedicated sound box structure with specific local features (sound outlet positioned at the front, circuit board positioned away from the back cover). This localized structural design ensures that the speakers maintain spatial sound characteristics while keeping the overall device compact.

Inventive Principle:
Principle #3Local quality

3Reliability

If the circuit board is positioned away from the back cover, then the antenna reception is improved, but the device thickness increases

Engineering Contradiction:
Improveantenna receptionVSAvoiddevice thickness
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The patent resolves the thickness issue by changing the spatial arrangement to another dimension - positioning the circuit board between the structural member and frame rather than between the sound member and back cover. This dimensional repositioning allows the circuit board to be away from the antenna in the vertical dimension while maintaining compact overall device thickness.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A portable electronic apparatus includes a structural member, a sound member, a circuit board, and a frame. The structural member has an opening and an accommodating recess. The sound member is accommodated in the accommodating recess, and has a top surface, a bottom surface, and a sound outlet. The sound outlet is located at the top surface. The circuit board cover plates the opening and has a first through hole corresponding to the sound outlet. The circuit board is disposed between the frame and the structural member. The frame has a second through hole corresponding to the sound outlet. The sound member is electrically connected to the circuit board. The sound outlet is communicated with the first and second through holes.
