Front Camera Acoustic Passage Layout for Central Sound Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals face reduced sound volume and quality due to the eccentric placement of acoustic components, which affects sound radiation from the center of the device, especially as display sizes increase and speaker openings are moved away from the center.
Innovation Solution
An electronic device design with a housing featuring a transparent part, openings adjacent to the transparent part, a camera with an image sensor facing through the transparent part, and an acoustic component with a diaphragm that generates sound and is connected to passages leading to the openings, allowing sound to be radiated centrally despite eccentric placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera is disposed at the center of the front surface, then the display area can be maximized, but the sound volume decreases because the acoustic component cannot be positioned at the center
Solution Approach 1:
The patent divides the sound radiation function into two separate paths: a first passage for sound waves traveling in a first direction and a second passage for sound waves traveling in a second direction. This segmentation allows the acoustic component to be positioned eccentrically while still achieving central sound radiation through multiple directional paths.
Solution Approach 2:
The patent transitions from a single-direction sound radiation approach to a multi-dimensional approach by introducing passages in different directions (first direction and second direction). This dimensional expansion enables the acoustic component to radiate sound effectively despite its eccentric position relative to the center opening.
2Area of stationary object
If the acoustic component is disposed eccentric from the center, then the camera can be positioned at the center, but sound does not radiate actively from the center resulting in decreased sound volume
Solution Approach 1:
The patent segments the sound radiation path into multiple directional passages, allowing the eccentric acoustic component to project sound through different routes that converge at the central opening, thereby maintaining central sound radiation despite eccentric component placement.
Solution Approach 2:
The first and second passages act as intermediaries that transfer sound waves from the eccentric acoustic component to the central opening. These passages mediate the sound transmission process, enabling sound to originate from the eccentric component while radiating from the center.
3Area of stationary object
If the openings are formed close to the top edge to accommodate larger display, then the display size increases, but the acoustic component must be disposed eccentric resulting in decreased sound quality
Solution Approach 1:
The patent divides sound radiation into multiple directional passages, enabling the acoustic component to be positioned in the upper region near the display while still achieving effective sound radiation through segmented paths that maintain sound quality.
Solution Approach 2:
The patent introduces multi-dimensional sound propagation paths (first direction and second direction passages) that allow the acoustic component to be positioned away from the center while maintaining sound quality through alternative radiation routes.
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
The design ensures stable sound quality and volume by actively radiating sound from the center, even with eccentric acoustic component placement, and allows for a larger display area by positioning openings at the center of the device.
Implementation Method 1
an acoustic component disposed between the first surface and the second surface, and comprising a diaphragm configured to generate sound and move the sound in at least one of the first direction or the second direction
