Suspended Speaker Vibrating Body for Wide Sound Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speaker devices fixed to ceilings in rooms can create a feeling of oppression and have limited sound output range due to their design, while lighting fixtures with built-in speakers struggle to produce loud sound over a wide area.
Innovation Solution
A speaker device with a main body and a vibrating body connected by a string or rod-shaped vibration transmitting member, where the vibrating body is a thin, disk-shaped lighting fixture that emits sound and light, allowing for wide sound distribution without occupying floor space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a speaker device is fixed to the ceiling in a conventional design, then it can be mounted at a predetermined position, but it creates a feeling of oppression and has limited sound output range
Solution Approach 1:
The speaker device is divided into two main segments: a main body part mounted on the ceiling and a vibrating body suspended below it. This segmentation allows the mounted portion to be compact and unobtrusive while the suspended vibrating body extends the sound radiation space downward, reducing the feeling of oppression and expanding sound output range.
Solution Approach 2:
The invention transitions from a two-dimensional ceiling-mounted surface to a three-dimensional configuration by suspending the vibrating body vertically below the main body. This dimensional extension allows sound to radiate over a wider area without increasing the footprint on the ceiling, thereby reducing oppression while expanding sound coverage.
2Volume of moving object
If a lighting fixture with built-in speaker is used, then spatial efficiency is improved, but sound output over a wide area is limited
Solution Approach 1:
The vibrating body is extended vertically downward from the main body in the third dimension, allowing sound to radiate over a wider area without increasing the horizontal footprint. This vertical extension maintains spatial efficiency while expanding sound coverage area.
Solution Approach 2:
The invention changes the physical configuration parameter by suspending the vibrating body at a distance below the main body rather than integrating it tightly. This parameter change allows the vibrating body to move freely and radiate sound over a larger volume of space, overcoming the limitation of compact integrated designs.
3Object-affected harmful factors
If the vibrating body is placed for hanging from the first actuator by the first vibration transmitting member, then sound output over a wide range is achieved, but device complexity increases
Solution Approach 1:
A vibration transmitting member (string or rod) is introduced as an intermediary element to connect the actuator in the main body to the vibrating body. This simple intermediary component enables the transmission of vibrations while keeping the overall structure relatively simple, avoiding complex mechanical linkages.
Solution Approach 2:
The invention replaces complex mechanical coupling systems with a simpler vibration transmitting member that can be a string or rod. This substitution simplifies the structure while effectively transmitting vibrations from the actuator to the vibrating body, achieving wide sound output without excessive complexity.

AI summary
A speaker device includes: a main body part mounted at a predetermined position; a first actuator that is housed in the main body part and generates vibration corresponding to an audio signal that is input; a vibrating body; and vibration transmitting member. The vibrating body vibrates with vibration transmitted from the outside to generate sound. The vibration transmitting member is a string-shaped or rod-shaped member that transmits the vibration generated by the first actuator to the vibrating body. The vibrating body is placed for hanging from the first actuator by the vibration transmitting member.
