Handheld interface for speaker location
View Patent ↗An interface for balancing speaker sound for use in consumer electronics and professional sound reinforcement field features a wireless speaker array. Optimization is accomplished by assigning the correct audio channel to each wireless speaker by a “chime” sound with multiple frequency components, and optimizing the sound of the speaker array by providing a wireless transmitter device with precise positions of each item for subsequent optimization of relative gain and delay for each speaker relative to the sweet spot.
1. A method for management of speaker sound with a wireless transmitter device and a handheld speaker management unit having a speaker identification utility, a speaker positioning utility, and a processor coupled to a memory and display screen, the method comprising:
a) collecting data representative of a plurality of speaker location values into the handheld speaker management unit;
b) displaying a map of collection data;
c) comparing the collected data whether user entered location data;
d) prompting the wireless transmitter device to generate a chime at each speaker;
e) permitting adjustment of speaker location values;
f) generating a speaker index;
g) evaluating whether a channel assignment is appropriate for each speaker; and
h) permitting a user to override the channel assignment.
2. The method of claim 1 , in which location data includes a distance from at least two wall points and from a sweet-spot.
3. The method of claim 2 , further comprising the step of calculating a delay value for each speaker and transmitting at least one delay value to at least one speaker.
4. The method of claim 3 , further comprising the step of determining an average distance value for each speaker, transmitting at least one speaker location value and the average distance value to at least one speaker, and determining a relative volume offset for each speaker.
5. A system comprising: a processor configured to analyze speaker location data, the speaker location data comprising data describing speaker location relative to walls, audio source, and a sweet-spot; a processor configured to rank each speaker position in a audio channel index according the each respective speaker position; a processor configured to select for display all speaker positions having a audio channel and the sweet-spot; a processor configured to draw a schematic map comprising speaker position, a sweet-spot indicator, and audio qualities selected for display; a display configured to display the schematic map; and a user interface to configured to accept user inputs instructing one or more of the processors to generate or modify the schematic map.
6. The system of claim 5 , wherein the processors are distributed among one or more devices in the system.
7. The system of claim 6 , wherein the processors exist in one or more servers and a handheld device.
8. The system of claim 5 , wherein the processors are all embodied in a single processor in a handheld device.
9. The system of claim 5 , wherein the audio qualities include at least one of a group consisting of volume, delay, gain, and channel assignment.
10. The system of claim 5 , wherein the speaker positions can be re-ranked.
