Headphones measuring heart-rate

Abstract

The invention relates to headphones and a method for listening to music or some other audio signal, which headphones comprise at least one sound source such as a an earphone to be placed in the vicinity of the ear, for producing sound, and a galvanic conductor for feeding an electrical signal from a signal source, such as a music player or similar, to the sound source. In accordance with the invention at least one sound source is equipped with means for measuring heart rate, as well as means for forwarding heart-rate information wirelessly.

1 . Headphones for listening to music or some other audio signal, which comprise
 at least one sound source configured to be placed in the vicinity of the ear, for producing sound, said sound source being equipped with means for measuring heart-rate, as well as means for forwarding heart-rate information wirelessly, and   means for starting heart-rate measurement once an audio signal fed to the headphones is detected.   
     
     
         2 . The headphones according to  claim 1 , wherein the heart-rate measurement is implemented using infrared technology. 
     
     
         3 . The headphones according to  claim 1 , wherein the heart-rate measurement is implemented from the outer auditory canal using infrared technology. 
     
     
         4 . The headphones according to  claim 1 , wherein power supply to the measurement and transmission means is implemented using a dry-cell battery or rechargeable battery. 
     
     
         5 . The headphones according to  claim 1 , wherein power supply to the measurement and forwarding means is implemented from the audio signal. 
     
     
         6 . A method in headphones, comprising the steps of:
 feeding a signal from a signal source to a sound source,   equipping the sound source with means for measuring heart-rate, as well as means for forwarding heart-rate information wirelessly, and   starting heart-rate measurement once an audio signal fed to the headphones is detected.   
     
     
         7 . The method according to  claim 6 , wherein the heart-rate measurement is implemented using infrared technology. 
     
     
         8 . The method according to  claim 6 , wherein the heart-rate measurement is implemented from the outer auditory canal using infrared technology. 
     
     
         9 . The method according to  claim 6 , wherein power supply to the measurement and transmission means is implemented using a dry-cell battery or rechargeable battery. 
     
     
         10 . The method according to  claim 6 , wherein power supply to the measurement and forwarding means is implemented from the audio signal.
