A laser receiver (1) for acoustically indicating a laser beam, including a housing (4), a detector unit (6) that ascertains the actual position (2) of the laser beam, an evaluation unit (8) that determines the difference between the actual position (2) and the target position (3), and an acoustic indication device (7) that uses an acoustic signal to indicate whether the actual position (2) of the laser beam is above, below or at the target position (3), wherein a control unit (9) is provided that, as a function of the difference between the actual position (2) and the target position (3), generates a scanning signal to modulate a basic signal, and then sends the scanning signal to the acoustic indication device (7). |
