The invention relates to medical equipment, designed to sound the alarm to change the posture of the human body and can be used to generate skill correct posture, prevention and correction of functional disturbances of posture and treatment of orthopedic diseases and to control the drivers posture while driving. The apparatus comprises a housing (1), a power unit (5), generator (4) signals disorders predetermined position, the input of which is electrically connected to the chopper signal emitter notifying human abuse posture, the input of which is electrically connected to the output of the generator (4) signals violations predetermined position, an accelerometer (6) that detects the tilt angle of the device relative to the vertical and supplying an electronic signal generator (4) signals disorders predetermined position, and a fastening member (2). The distinctive features of the device is that the emitter (3) is made audible signal, a fastening element (2) - with the possibility of its attachment to the users ear. Applications in the sound signal device allows its use in a noisy street and while driving, and even when driving on the bumpy road. Performing attachment to the users ear allows receiving signals driver of the vehicle in the event of falling asleep, even when he is rejected only the head, without changing the body position. 2 ZP f ly-3-yl.
