Samsung patents method to measure speaker height using sound
This filing describes a technique where a device plays a specific sound from its speakers and uses built-in microphones to record the echo. By analyzing how long the sound takes to reach different microphones, the system calculates the physical distance and determines the vertical angle of the speakers.
In the filing’s own words
In one embodiment, a method includes emitting, by each of multiple discrete loudspeakers, an excitation stimulus; and measuring, by each of multiple microphones, a response at that microphone due to the stimuli. Each of the discrete loudspeakers is proximal with at least one microphone in the set of microphones, and the microphones include at least two microphones separated by a predetermined distance. The method further includes determining, by deconvolving the microphone measurements, a set of loudspeaker room impulse responses; determining, from the set of loudspeaker room impulse responses, a distance between each discrete loudspeaker and each microphone; and estimating, based on the determined distances, an elevation angle of each of the discrete loudspeakers.
What exactly they claim (claim 1)
1. A method comprising: emitting, by each of a plurality of discrete loudspeakers, an excitation stimulus; measuring, by each of a plurality of microphones, a response at that microphone due to the emitted excitation stimuli, wherein: each of the discrete loudspeakers is proximal with at least one microphone in the set of microphones; and the plurality of microphones includes at least two microphones separated by a predetermined distance; determining, by deconvolving the microphone measurements, a set of loudspeaker room impulse responses; determining, from the set of loudspeaker room impulse responses, a distance between each discrete loudspeaker and each microphone; and estimating, based on the determined distances, an elevation angle of each of the plurality of discrete loudspeakers.
