Adjustable Speaker Module with Lifting Mechanism for Directional Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional built-in speaker modules in consumer electronic devices, such as liquid crystal televisions and notebook computers, lack the ability to adjust sound output direction and often compromise on design aesthetics due to their fixed positioning.
Innovation Solution
A speaker module with a lifting mechanism comprising inclined lifting components and a mechanical or electromagnetic driver, allowing the speaker unit to rotate relative to its supporter, enabling adjustable sound direction while maintaining a compact and aesthetically pleasing design. This module includes a base, supporter, speaker unit, and lifting mechanism with a rack and gear system or electromagnetic components for precise angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the speaker module is fixed on the base, then the structure is simple and stable, but the sound output direction cannot be adjusted
Solution Approach 1:
The speaker module transitions from a fixed static position to a dynamically adjustable position. The lifting mechanism enables the speaker unit to rotate and change its orientation relative to the base, allowing dynamic adjustment of sound output direction while maintaining structural integrity through controlled mechanical movement.
Solution Approach 2:
The speaker system is divided into separable components: a fixed base and a movable speaker unit. The speaker unit can be detached from the base and repositioned independently, allowing users to adjust sound direction without affecting the overall structure. This segmentation enables versatility while keeping each component relatively simple.
2Adaptability or versatility
If the detachable speaker module is drawn out for angle adjustment, then the rotary angle can be adjusted to 60 degrees, but the casing loses artistic appearance
Solution Approach 1:
The adjustable speaker module is nested within the casing structure. The speaker unit can be positioned in multiple orientations (including the 60-degree angle adjustment) while remaining contained within the overall device footprint. This nesting allows angle adjustment functionality without compromising the external aesthetic appearance of the casing.
Solution Approach 2:
The speaker module incorporates dynamic positioning capability within the casing, allowing it to rotate and adjust angles while remaining integrated with the device. This dynamic adjustment mechanism enables versatility in sound direction without requiring external detachable components that would affect appearance.
3Length of moving object
If the speaker module is designed for thin structure, then it matches the thin trend of liquid crystal television, but the sound field quality deteriorates
Solution Approach 1:
The speaker module compensates for its thin profile by introducing rotational freedom in another dimension. While the thickness is reduced to match thin television designs, the module can rotate and reposition itself to optimize sound projection. This dimensional adjustment allows the thin speaker to achieve better sound field quality by directing sound appropriately in three-dimensional space.
Solution Approach 2:
The thin speaker module incorporates dynamic adjustment capability, allowing it to change its orientation and positioning relative to the base. This dynamic repositioning enables the thin speaker to optimize its sound projection direction, compensating for the limitations imposed by its reduced thickness and improving overall sound field quality.
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
Enables the speaker module to automatically adjust its sound output direction towards the user, enhancing sound quality by simulating stereo sound and improving low-frequency sound performance, while maintaining a slim and artistic appearance in electronic devices.
Implementation Method 1
The electromagnetic element is disposed on the second lifting component. The magnetic force is generated between the magnetic element and the electromagnetic element by variation of magnetic flux.

AI summary
A speaker module is capable of adjusting an outputting direction of an audio signal. The speaker module includes a base, a supporter, a speaker and a lifting mechanism. The supporter is disposed on the base. The speaker includes a speaker unit and an arm. The speaker unit is suspended above the base for generating the audio signal. A first end of the arm is connected to a lateral side of the speaker unit, and a second end of the arm is movably disposed on the supporter. The lifting mechanism includes a first lifting component disposed on the speaker unit, a body disposed on the base, and a second lifting component disposed on the body. The second lifting component can adjust a height of the first lifting component, so as to rotate the speaker unit relative to the supporter.
