Receiver Module Switching Sound Output Between Two Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for terminal devices with two receivers occupy significant mounting space on the main circuit board, limiting the space for other components and complicating sound production at multiple positions.
Innovation Solution
A receiver module with a housing, a receiver, a drive assembly, and a soundproofing assembly, where the soundproofing assembly can switch between two sound-emitting holes to direct sound output from a single receiver to different positions, reducing the need for multiple receivers and minimizing board space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two receivers are mounted in a terminal device to enable sound production at two different positions, then the sound production capability at multiple positions is improved, but the mounting space occupied on the main circuit board increases
Solution Approach 1:
A single receiver is designed to serve multiple functions by directing sound to different positions through switching mechanisms. The receiver can alternatively connect to first and second sound outlets, enabling it to fulfill the role of what would traditionally require two separate receivers, thus reducing mounting space while maintaining multi-position sound production capability
Solution Approach 2:
The receiver's connection state is made dynamic through switching mechanisms (such as electromagnetic valves or movable components) that can alternatively connect the receiver to different sound outlets. This dynamic switching allows one receiver to adaptively serve multiple positions, resolving the contradiction between space efficiency and sound production versatility

AI summary
This disclosure provides a receiver module and a terminal device. The receiver module includes a housing, a receiver, a drive assembly and a soundproofing assembly, where the housing is internally provided with an accommodating space, the receiver is arranged in the accommodating space, and the housing and the receiver fit together to form a sound cavity, a sound-emitting side of the receiver facing towards the sound cavity; the housing is provided with a first sound-emitting hole and a second sound-emitting hole; the drive assembly and the soundproofing assembly are connected, and the drive assembly is configured to drive the soundproofing assembly to be in a first state or a second state; when the soundproofing assembly is in the first state, the second sound-emitting hole is in communication with the sound cavity, and the soundproofing assembly blocks off the first sound-emitting hole from the sound cavity; and when the soundproofing assembly is in the second state, the first sound-emitting hole is in communication with the sound cavity, and the soundproofing assembly blocks off the second sound-emitting hole from the sound cavity.
