Aural measurements from earphone output speakers
First Claim
1. A method of using an earphone output speaker as a microphone for a phone call between a plurality of participants, comprising:
- playing a remote voice signal received from a remote client terminal with an electro- acoustic output transducer, wherein said remote voice signal represents a voice of a remote participant recorded from the remote client terminal;
recording a first local voice signal from same said electro-acoustic output transducer, wherein said first local voice signal represents a voice of a local participant using a local client terminal;
calculating a transmission voice signal based on a function combining said first local voice signal, said remote voice signal, and filtration coefficients, using a processing unit of said local client terminal; and
sending said transmission voice signal through an output interface of said local client terminal, thereby enabling acoustic voice playing of said transmission voice signal by said remote client terminal at a remote location for a phone call communication.

Abstract
According to some embodiments of the present invention there is provided a method of using an earphone output speaker as a microphone for a phone call between two and/or more participants, or for measuring biometric data of a user. The method may comprise playing a received signal to an electro-acoustic output transducer of an earphone. The method may comprise instructing an audio processing circuit of a local client terminal to record an audio signal from the same electro-acoustic output transducer. The method may comprise calculating a voice signal and/or a biometric measurement based on a function combining the recorded audio signal, the received signal, and filtration coefficients, using a processing unit of the local client terminal. The method may comprise sending the voice signal and/or a biometric measurement through an output interface of the local client terminal.

11. A system, comprising:
-
a processor; and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause performance of operations that comprise; playing a remote voice signal received from a remote client terminal with an electro-acoustic output transducer, wherein said remote voice signal represents a voice of a remote participant recorded from the remote client terminal; recording a first local voice signal from same said electro-acoustic output transducer, wherein said first local voice signal represents a voice of a local participant using a local client terminal; calculating a transmission voice signal based on a function combining said first local voice signal, said remote voice signal, and filtration coefficients, using a processing unit of said local client terminal; and sending said transmission voice signal through an output interface of said local client terminal, thereby enabling acoustic voice playing of said transmission voice signal by said remote client terminal at a remote location for a phone call communication. - View Dependent Claims (16, 17, 18, 19, 20)

12. A device for sending a voice signal during a phone call, comprising:
-
a first interface for sending a transmission voice signal of a local participant in a phone conversation and receiving a remote voice signal of a remote participant in said phone conversation; a second interface for connecting an earphone to said device; at least one storage unit comprising sets of processor instructions for performing actions that include; playing the remote voice signal to an electro-acoustic transducer of said earphone; recording a first local voice signal using same said electro-acoustic transducer of said earphone; computing said transmission voice signal from said first local voice signal, said remote voice signal, and filtration coefficients; sending, using the first interface, said transmission voice signal to a player device of said remote participant in said phone conversation; and at least one processing unit configured for retrieving said sets of processor instructions from said at least one storage unit, and executing said sets of processor instructions. - View Dependent Claims (13)
