Solution Overview
Problem
Existing audio systems require cumbersome individual adjustments for multiple receivers outputting the same audio data, as they lack automatic control over the output state of audio data among receivers.
Innovation Solution
An audio apparatus comprising a receiver, a sound emitter, a generator for creating sound emission control information, and a transmitter to broadcast this information to other apparatuses, enabling automatic control of audio data output among receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual manual adjustments are performed for each receiver to balance volume and range, then sound output balance can be achieved, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system enables automatic self-adjustment of audio output parameters among multiple receivers. Each receiver automatically receives control information from the transmitter and adjusts its own volume and frequency range settings without requiring manual intervention, thereby eliminating the need for users to perform time-consuming individual adjustments.
Solution Approach 2:
A transmitter is introduced as an intermediary device that generates and distributes control information to multiple receivers. This intermediary automates the coordination between receivers by sending standardized control signals that automatically adjust volume and frequency settings, replacing the need for manual individual adjustment of each receiver.
2Adaptability or versatility
If control buttons are disposed in the transmitter for operating receivers, then centralized control is achieved, but individual receiver adjustments remain necessary and cumbersome
Solution Approach 1:
The transmitter is designed with multi-functionality, serving both as an audio signal source and as a centralized control device. It generates control information that can be universally applied to multiple different types of receivers, enabling a single device to perform multiple functions (audio transmission and automatic control) without requiring separate control mechanisms for each receiver.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with automated electronic control signals. Instead of requiring physical button presses or manual settings on each receiver, the system uses electronic transmission of control information that automatically configures receiver parameters, substituting mechanical user interactions with automated digital control.
3Productivity
If multiple receivers simultaneously output the same audio data, then audio coverage is improved, but unbalanced volume and range create poor sound quality
Solution Approach 1:
The system implements automatic feedback control where the transmitter monitors the audio output environment and continuously adjusts control information sent to receivers. This feedback mechanism ensures that volume and frequency settings are automatically optimized to maintain balanced sound quality across all receivers simultaneously outputting audio data.
Solution Approach 2:
The transmitter dynamically changes output parameters (volume level, frequency range) of each receiver based on the audio environment and receiver characteristics. By automatically adjusting these parameters for each receiver, the system ensures balanced sound output across multiple devices without requiring manual calibration, thus maintaining high sound quality precision while enabling simultaneous audio output.
Data Source
AI summary
An audio apparatus includes a network interface, a receiver, at least one storage, and at least one processor. The processor is configured to determine that the audio apparatus is in a state capable of communicating with the other audio apparatus via the network interface. The processor is also configured to receive audio data via the receiver transmitted from an external apparatus different from the other audio apparatus. The processor is also configured to output a sound based on the received audio data. The processor is also configured to transmit the sound emission control information stored in the at least one storage to the other audio apparatus. The sound emission control information includes one or more of a sound volume, and a frequency band.
