Speaker apparatus, audio data supply apparatus, and audio data reproduction system

An audio data supply apparatus comprising:

• an audio data processing unit configured to subject audio data to sound quality adjustment processing according to positional information sent from a speaker apparatus;
• and
• a supply unit configured to supply the audio data subjected to the sound quality adjustment processing to a corresponding speaker apparatus by communication,
• wherein the positional information is information based on a first distance to a first detection object, the first detection object existing on one side in a vertical direction substantially orthogonal to a sound radiation direction of the speaker apparatus, and a second distance to a second detection object, the second detection object existing on the one side in the vertical direction substantially orthogonal to the sound radiation direction at a greater distance than the first distance, wherein the first and second detection objects are not speaker apparatuses.

An audio data reproduction system comprising:

• a speaker apparatus;
• and an audio data supply apparatus configured to supply audio data to the speaker apparatus,
• wherein the speaker apparatus includes
• a measuring unit configured to measure a first distance to a first detection object, the first detection object existing on one side in a vertical direction substantially orthogonal to a sound radiation direction, and a second distance to a second detection object, the second detection object existing on the one side in the vertical direction substantially orthogonal to the sound radiation direction at a greater distance than the first distance, wherein the first and second detection objects are not speaker apparatuses, and
• a communication unit configured to send positional information based on the first distance and the second distance to the audio data supply apparatus by communication, and
• the audio data supply apparatus includes
• an audio data processing unit configured to subject the audio data to sound quality adjustment processing according to the positional information sent from the speaker apparatus, and
• a supply unit configured to supply the audio data subjected to the sound quality adjustment processing to a corresponding speaker apparatus by communication.
