Abstract

A method and device for repeating an audible segment for use in an audio apparatus wherein an audio signal is converted into audible sounds. The audio signal is received via memory which continuously stores a predetermined time segment thereof and which is able to read out the stored audio signal segment at an output thereof. A manually actuatable switch is operable upon manual actuation by a user for maintaining the storage of a predetermined time segment of the audio signal immediately before the manual actuation and for reading out the stored audio signal at least once after the manual actuation. The read out stored audio signal is directed to an output device so that it can be heard by the user.

Claims

1. A device for repeating an audible segment for use in an audio apparatus wherein an output circuit is receptive of an audio signal for converting the audio signal into audible sounds, the device comprising:

a memory receptive of an audio signal for continuously storing a predetermined time segment thereof and for reading out a stored audio signal segment at an output thereof; and

a manually actuatable switch operative upon manual actuation by a user for maintaining the storage of said predetermined time segment of the audio signal by said memory immediately before the manual actuation and for reading out the stored audio signal at least once after said manual actuation; and

circuitry for directing the read out stored audio signal to the output circuit.

2. The device according to claim 1, wherein the manually actuatable switch comprises a pushbutton switch.

3. The device according to claim 1, wherein the circuit for directing the stored output signal to the output circuit comprises an analog switch.

4. The device according to claim 1, wherein the circuit for directing the stored output signal to the output circuit comprises a digital switch.

5. The device according to claim 1, wherein the memory comprises a random access memory.

6. The device according to claim 1, wherein the memory comprises two memories, wherein the manually actuatable switch comprises two switches and wherein the circuit for directing the stored audio signal to the output circuit comprises a circuit for selecting between the outputs of the two memories dependent upon the order of actuation of the two switches.

7. A method for repeating an audible segment, the method comprising the steps of:

continuously storing a predetermined time segment of an audio signal;

manually actuating a switch;

maintaining the storage of said predetermined time segment of the audio signal immediately before the manual actuation of the switch;

reading out the stored audio signal at least once after said manual actuation; and

directing the read out stored audio signal to an output circuit.

8. The method according to claim 7, wherein the step of manually actuating comprises pushing a pushbutton switch.

9. The method according to claim 7, wherein the step of directing the stored output signal to the output means comprises providing an analog switch.

10. The method according to claim 7, wherein the step of directing the stored output signal to the output means comprises providing a digital switch.

11. The method according to claim 7, wherein the step of storing comprises writing data into a random access memory.

12. The method according to claim 7, wherein the step of storing comprises writing data into two memories, wherein the step of manually actuating comprises providing two switches and wherein the step of directing the stored audio signal to the output means comprises selecting between the outputs of the two memories dependent upon the order of actuation of the two switches.
