ELEKTRONISCHES NOTIZGERÄTELECTRONIC NOTE TAKER
Die Erfindung betrifft ein elektronisches Tonaufnahmegerät ohne mechanisch bewegten Tonträger und dessen Antrieb.The invention relates to an electronic sound recording device without a mechanically moving sound carrier and its drive.
Tonträgergeräte wie z.B. Tonbandgeräte, Diktiergeräte und Schallplattengeräte gibt es bereits in den verschiedensten Variationen. All diesen Geräten ist der Nachteil einer aufwendigen, voluminösen und teuren Mechanik für Antrieb und TonträgerfUhrung gemeinsam.Sound storage devices such as tape recorders, dictation machines and record players already exist in a wide variety of variations. All of these devices have the disadvantage of complex, bulky and expensive mechanisms for the drive and sound carrier guide.
Die erfindungsgemäße Konstruktion ermöglicht mit minimalstem Materialaufwand auf einfache Weise eine Lösung der Problemstellung.The construction according to the invention enables a simple solution to the problem with minimal material expenditure.
Der Vorteil des Gerätes besteht durch den Wegfall der mechanischen Tonträgeraufnahmevorrichtungen und dessen Antrieb, in den geringen äußeren Abmessungen (FUllhalterformat möglich), Wegfall von Verschleißerscheinungen in der Mechanik - dadurch geringerer Reparaturanfall -, kein mechanischer Tonträger (Band o. Platte) vorhanden, Beschränkung auf den Sprachfrequenzbereich zwischen ioo Hz und 5.000 Hz sowie beliebig oftes Aufzeichnen bzw. Speichern und Abhören mit einem Gerät.The advantage of the device is that there is no need for mechanical sound recording devices and their drive, the small external dimensions (fountain pen format possible), no signs of wear and tear in the mechanics - thus fewer repairs -, no mechanical sound carrier (tape or record) is present, the device is limited to the speech frequency range between 100 Hz and 5,000 Hz, and you can record, save and listen to as often as you like with one device.
Ein weit-srer Vorteil besteht darin, daß das Gerät leicht transportierbar und dadurch als ständiges Begleitgerät geeignet ist.Another advantage is that the device is easy to transport and is therefore suitable as a permanent companion.
Der Nachteil der großen Gehäuseformen der bekannten Diktiergeräte durch ihre komplizierte Antriebsmechanik für die Spulenmitnehmer sowie deren erheblicher mechanischer Fertigungsaufwand entfällt.The disadvantage of the large housing shapes of the known dictation devices due to their complicated drive mechanism for the coil drivers as well as their considerable mechanical manufacturing effort is eliminated.

Prinzip istf daß im Aufr?ahme-Modus Über ein Mikrofon (2) Und einen A/D-Wandler (6) die Tonsignäle digitalisiert auf einen Speicher (7) aufgebracht werden* im Wiedergabe-Modus werden die abgespeicherten Tönsignäle vom Speicher (7) Über einen D/Ä-^Wandler (8) und einen NF-Versta'rker (9) durch einen Signalwandler (4.) hörbar gemacht,The principle is that in the recording mode, the audio signals are digitized and applied to a memory (7) via a microphone (2) and an A/D converter (6). In the playback mode, the stored audio signals from the memory (7) are made audible by a signal converter (4) via a D/A converter (8) and an NF amplifier (9).
Die Zeichnung Fig, i zeigt eine vorteilhafte Zusammenstellung der einzelnen elektronischen Bausteine als Blöckdiägfämfn.The drawing Fig. i shows an advantageous arrangement of the individual electronic components as a block diagram.
Die Zeichnung Fig. 2 zeigt eine mögliche Ausgestaltung eines kompletten Gerätes.The drawing Fig. 2 shows a possible design of a complete device.
