Music Delivery Volume Control for Clear Interphone Conversations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music delivering systems struggle to maintain clear interphone conversations when music is being reproduced, as the user's voice is often drowned out by the music.
Innovation Solution
A music delivering apparatus and method that includes a storing unit for musical data, a sound collecting unit for voice input, a mixer to combine audio and musical data, and a volume control unit to lower the musical data volume, ensuring the voice is not overwhelmed by the music, even when music is being reproduced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If music is reproduced on the client side at normal volume, then the music quality is maintained, but the user's voice is drowned out and interphone conversation cannot be carried on properly
Solution Approach 1:
The system dynamically adjusts the volume of musical data based on whether audio data (voice) is being transmitted. When interphone conversation is active, the music volume is automatically lowered to allow clear voice transmission. This dynamic volume adjustment resolves the contradiction by making the music volume adaptive rather than static, ensuring conversation clarity when needed while maintaining normal music playback quality when not in use.
2Reliability
If the volume of musical data is lowered while audio data is mixed, then clear voice reproduction is achieved, but music playback quality is degraded
Solution Approach 1:
The volume control unit implements dynamic volume adjustment that temporarily lowers music volume only during active interphone conversations. When no voice transmission is occurring, the music volume returns to normal levels. This temporal and conditional adjustment resolves the contradiction by ensuring high voice clarity during conversations while preserving music playback quality during normal listening.
Solution Approach 2:
The system changes the volume parameter of musical data based on the operational state (whether audio data is being supplied). By detecting the presence of audio data and adjusting the music volume parameter accordingly, the system optimizes both voice reproduction clarity and music playback quality for different operational scenarios.

AI summary
A music delivering apparatus includes a storing unit that stores musical data, a sound collecting unit that collects a voice from outside to output audio data, a reading unit that reads the musical data from the storing unit, a mixer that mixes the audio data with the musical data read out by the reading unit to output sound data, a transmitting unit that transmits the sound data to a client, and a volume control unit that lowers volume of the musical data that is read out by the reading unit and supplied to the mixer while the audio data is supplied to the mixer.
