Description

2 AT010 414U1

The invention relates to a device for sound recording with a switch actuated by a microphone, a memory connected to the microphone via an analog-to-digital converter memory for the audio signals and with a processing stage for the audio signals read-out device for the memory.

Sound recording devices, in particular for voice recording, are known as dictation machines in various embodiments, wherein the digital storage of the sound signals can make a significant contribution to miniaturization. However, the processing stage for the sound signals read out from the memory requires not only a not inconsiderable additional expenditure in the area of the circuit design, but also an increased use of energy.

The invention is therefore based on the object, a device for sound recording of the type described in such a way that an easy-to-use, a low energy use requiring, small handling unit is obtained, which is particularly suitable for recording voice notes.

The invention solves this problem by the fact that the microphone with the operating switch, the analog-to-digital converter and the memory arranged in a housing assembly with an interface connector for connecting to a separate device associated read-out device with subsequent processing stage forms.

Since, according to these measures, the read-out device with the subsequent processing stage for the sound signals read from the memory is assigned to a separate device, in particular a computer, the device can be constructed simply and be used, for example, in the form of a keyfob. About the interface connector, the device for reading the memory, a conventional external memory comparable to be connected to the computer to access the computer via the stored audio signals can.

Combining the microphone with the actuation switch, the analog-to-digital converter, and the memory into a separate package also ensures an essential prerequisite for a robust construction that can be housed in a corresponding housing. Particularly advantageous design conditions arise in this context, when the assembly is slidably mounted to push out the interface connector in a coupling position in the housing having a window for the microphone and the operation switch. In this case, it is unnecessary to line connections between the housing associated components and sliding in the housing construction parts. All that needs to be taken care of is an appropriate access to the controls, which can be ensured by a housing window for the microphone and the operating switch in a simple manner.

In the drawing, the subject invention is shown, for example. Show it

Fig. 1 shows a device according to the invention for sound recording in a schematic block diagram and

Fig. 2 shows the device in a simplified plan view.

As can be seen from Fig. 1, the audio recording device comprises a microphone 1, the analog electrical sound signals are converted by means of an analog-to-digital converter 2 for storage in a memory 3 into digital audio signals. For this recording of the sound signals, a control stage 4 is provided, which can be controlled via an actuating switch 5 and causes the memory of the microphone 1 recorded sound signals in the memory 3 due to this control.

Claims (2)

3 AT010 414U1 To reproduce the sound signals or to process them, the stored digital sound signals must be read from the memory 3 and sent to a processing stage 6. For this purpose, in a conventional manner, a read-out device 7 is provided, which, however, in contrast to conventional devices of this type is not the microphone 1 with the memory 3 comprehensive assembly 8, but a separate device 9, preferably a computer assigned. For the connection between the assembly 8 and the device 9, a standardized interface is provided, wherein the unit 8 associated with the interface connector 10 and the connector receptacle of the device 9 are designated 11. Via the interface 10, 11 can thus be controlled via the readout device 7 of the device 9, the control stage 4 of the assembly 8 in the sense of reading the memory 3, so that the processing stage 6 of the device 9 with the sound signals from the memory 3 for sound reproduction or another Evaluation of the sound signals can be applied. From Fig. 2 it can be seen that the assembly 8 is slidably mounted in a guide 12 of a housing 13, wherein the arrangement is such that the interface connector 10 of the assembly 8 from the rest position shown in FIG. 2 by moving the Assembly 8 can be pushed into a coupling position. The housing 13 forms a window 14 for the microphone 1 and the operating switch 5 of the assembly 8, which thus remains accessible despite its displaceability within the housing 13 for operation. Otherwise required connection lines between the housing 13 on the one hand and the assembly 8 on the other hand associated components can thus be omitted. Claims 1. A sound recording apparatus comprising a microphone operable by means of a switch, a memory for the sound signals connected to the microphone via an analog-to-digital converter, and a read-out means for the memory connected upstream of a processing stage for the sound signals, characterized in that the microphone ( 1) with the actuating switch (5), the analog-digital converter (2) and the memory (3) arranged in a housing (13) assembly (8) with an interface connector (10) for connection to a separate device (9) associated read-out device (7) with subsequent processing stage (6). 2. Apparatus according to claim 1, characterized in that the assembly (8) for pushing out the interface connector (10) is slidably mounted in a coupling position in the housing (13) having a window (14) for the microphone (1) and the actuating switch (5).
