Abstract
A speaker with a digital signal processor is disclosed. In one aspect, a speaker comprises at least one electromechanical transducer configured to convert an electrical audio signal into sound and a digital signal processor configured to process an audio signal and send the processed audio signal to the electromechanical transducer directly or indirectly.
Claims24
A method of configuring a speaker in a room to compensate for secondary reflections off an object in the room, the speaker comprising a digital signal processor which comprises tunable secondary reflection correction filters, the method comprising:
- identifying secondary reflections off an object in the room where the speaker is located;
- generating secondary reflection correction coefficients to cancel secondary reflections arriving within a particular time limit;
- and
- saving the generated coefficients into the digital signal processor to configure the secondary reflection correction filters.
A device for configuring a speaker in a room to compensate for secondary reflections off an object in the room, the speaker comprising a digital signal processor which comprises tunable secondary reflection correction filters, the device comprising:
- a storage unit having stored therein a software module;
- and
- a control unit configured to perform the software module configured to:
- identify secondary reflections off an object in the room where the speaker is located;
- generate secondary reflection correction coefficients to cancel secondary reflections arriving within a particular time limit;
- and
- store the generated coefficients into the digital signal processor to configure the secondary reflection correction filters.
A method of configuring a speaker to compensate for manufacturing tolerances, the speaker comprising a digital signal processor having a tunable manufacturing correction filter, the method comprising:
- at a first location,
- sending a test audio signal to the speaker,
- measuring a frequency response of the speaker via a microphone;
- and
- storing a profile associated with the speaker, the profile comprising information related to the measured frequency response;
- at a second location remote from the first location,
- retrieving the stored profile;
- and
- configuring the manufacturing correction filter of the speaker to compensate for the manufacturing tolerances based on the retrieved profile.
A method of configuring a speaker to correct for manufacturing tolerances, the speaker comprising a digital signal processor having tunable manufacturing correction filters, the method comprising:
- retrieving a profile associated with the speaker, the profile comprising information related to a frequency response of the speaker, the frequency response being measured at a first location, the profile being retrieved at a second location remote from the first location;
- and
- configuring, at the second location, the manufacturing correction filters of the speaker to compensate for the manufacturing tolerances based on the retrieved profile.
A device for configuring a speaker to correct for manufacturing tolerances, the speaker comprising a digital signal processor having tunable manufacturing correction filters, comprising:
- a storage unit having stored therein a software module;
- and
- a control unit configured to perform the software module configured to:
- retrieve a profile associated with the speaker, the profile comprising information related to a frequency response of the speaker, the frequency response being measured at a first location, the profile being retrieved at a second location remote from the first location;
- and
- configure, at the second location, the manufacturing correction filters of the speaker to compensate for the manufacturing tolerances based on the retrieved profile.
A method of configuring a speaker to correct for manufacturing tolerances, the method comprising:
- measuring a frequency response of a speaker at a first location;
- storing at the first location a profile comprising information related to the measured frequency response of the speaker;
- delivering the stored profile to a second location remote from the first location;
- and
- configuring the speaker to correct for manufacturing tolerances based on the stored profile at the second location.
