Solution Overview

Problem

Conventional surface-mount speakers face issues with weight imbalance due to the heavy voltage converter, which increases the load on connecting members and makes it difficult to arrange the transformer centrally, affecting weight distribution.

Innovation Solution

The speaker unit mounting bracket incorporates a voltage converter, a base plate, and a cover to house the voltage converter, reducing the weight of the speaker unit and distributing the load more evenly by relocating the transformer to the bracket, allowing for better weight balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the voltage converter is included in the speaker unit, then the speaker unit can provide high impedance drive, but the weight of the speaker unit increases and applies large load to connecting members

Engineering Contradiction:

Improvehigh impedance drive capabilityVSAvoidweight of speaker unit

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent divides the speaker system into two separate parts: the speaker unit (containing only the speaker) and the bracket (containing the voltage converter). This segmentation allows the voltage converter to be mounted separately on the wall or ceiling, reducing the weight of the speaker unit while maintaining the high impedance drive capability through the integrated bracket assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The voltage converter is extracted from the speaker unit and placed in a separate bracket assembly. This extraction removes the heavy component from the speaker unit, reducing its weight and the load on connecting members, while the bracket independently provides the voltage conversion function for high impedance drive.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If the voltage converter is arranged in the speaker unit, then the speaker unit can provide high impedance drive, but it becomes difficult to arrange the transformer centrally, causing weight imbalance

Engineering Contradiction:

Improvehigh impedance drive capabilityVSAvoidweight balance of speaker unit

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

By separating the voltage converter from the speaker unit and placing it in an independent bracket, the patent enables centralized arrangement of the transformer in the bracket assembly. This segmentation allows the speaker unit to maintain its weight balance with the speaker centrally positioned, while the bracket independently houses the voltage converter.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The voltage converter is extracted from the speaker unit, allowing the speaker to be centrally positioned in the speaker unit for proper weight balance. The extracted voltage converter is then installed in the bracket, which can be positioned independently to achieve overall system balance.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An object is to reduce weight load acting on a connecting member that connects a speaker unit and a bracket and keep the weight balance of the right and left of the speaker unit. A speaker unit mounting bracket is provided with a voltage converter, a base plate, and a cover. The cover covers the voltage converter and the base plate.
