Description

Beschreibungdescription
Elektronische SpeicherkarteElectronic memory card
Die Erfindung liegt auf dem Gebiet elektronischer Speicher¬ karten, die beispielsweise in Form von Telefonkarten, Legiti- ationskarten oder anwenderspezifischen Karten bekannt sind, und betrifft eine elektronische Speicherkarte mit einem Halb¬ leiter-Speicher zur Speicherung veränderbarer Daten und mit einem Kartenkörper.The invention lies in the field of electronic memory cards, which are known, for example, in the form of telephone cards, legitimation cards or user-specific cards, and relates to an electronic memory card with a semiconductor memory for storing changeable data and with a card body.
Eine derartige elektrische Speicherkarte ist beispielsweise aus der EP-Bl-0 254 640 bekannt, die insbesondere die Her¬ stellung und die Ausbildung eines elektronischen Moduls mit einem Halbleiterbauelement (Halbleiterchip) für die Spei¬ cherkarte beschreibt. Das Halbleiterbauelement ist auf der Oberseite einer im wesentlichen ebenen Anordnung elektrischer Leiter befestigt. Die Unterseiten der Leiter bilden eine Schnittstelle zum Kontaktieren des Halbleiterbauelementes mit einer korrespondierenden externen Einrichtung. Diese externe Einrichtung kann über die Schnittstelle in bekannter Weise auf das Halbleiterbauelement und insbesondere auf in diesem oder zusätzlich zu diesem vorgesehene Speicher zugreifen.Such an electrical memory card is known, for example, from EP-B1-0 254 640, which describes in particular the manufacture and design of an electronic module with a semiconductor component (semiconductor chip) for the memory card. The semiconductor component is attached to the top of an essentially planar arrangement of electrical conductors. The undersides of the conductors form an interface for contacting the semiconductor component with a corresponding external device. This external device can access the semiconductor component and in particular the memory provided in or in addition to it via the interface in a known manner.
Aus dem deutschen Gebrauchsmuster 93 16 734 ist eine insbe¬ sondere zur Beteiligung von Fernsehzuschauern an Fernsehspie¬ len oder Fernsehshows konzipierte Scheckkarte bekann . Diese Scheckkarte empfängt von dem Tonkanal eines Fernsehgeräts mindestens einen codierten Datensatz beinhaltende akustische Signale, die anschließend decodiert und einem Mikroprozessor zugeleitet werden. Der Mikroprozessor vergleicht die deco¬ dierten Signale mit in der Scheckkarte fest gespeicherten Identifikationsdaten und gibt bei zumindest teilweiser Obereinstimmung ein die Aufmerksamkeit des Benutzers erre- gendes akustisches Signal ab. Der Benutzer hat jedoch keine Möglichkeit, Kenntnis von den Identifikationsdaten selbst zu erhalten. Eine Veränderung der Identifikationsdaten ist ge- nausowenig möglich wie die Benutzung der Scheckkarte ohne Fernsehtonkanal.A check card designed especially for the participation of television viewers in television games or television shows is known from German utility model 93 16 734. This check card receives from the audio channel of a television set at least one encoded data record containing acoustic signals which are then decoded and sent to a microprocessor. The microprocessor compares the decoded signals with identification data permanently stored in the check card and emits an acoustic signal that catches the user's attention if it is at least partially in agreement. However, the user has no way of knowing the identification data himself. A change in the identification data is just as impossible as using the check card without a TV audio channel.
Ein besonders bekanntes Beispiel einer Speicherkarte (Chipkarte) sind Telefonkarten, in deren Halbleiterbauelement u. a. das jeweils noch zum Telefonieren zur Verfügung stehende Guthaben gespeichert ist. Ein Problem üblicher Chipkarten besteht darin, daß ohne externe Hilfsmittel der jeweilige Speicherinhalt nicht abfragbar ist.A particularly well-known example of a memory card (chip card) are telephone cards, in the semiconductor component u. a. the credit available for making calls is saved. A problem with conventional chip cards is that the respective memory content cannot be queried without external aids.
Die Aufgabe der Erfindung besteht daher in der Schaffung ei¬ ner elektronischen Speicherkarte, die ohne externe Hilfsmit¬ tel eine Ausgabe der von ihr gespeicherten veränderbaren Daten ermöglicht.The object of the invention is therefore to create an electronic memory card which enables the changeable data stored by it to be output without external aids.
Diese Aufgabe wird bei einer elektronischen Speicherkarte der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß mindestens ein Schallwandler aus dem Speicher ausgelesene Daten in akustische Signale wandelt, die dem Kartenbenutzer den Speicherinhalt unmittelbar angeben. Damit ist in vor¬ teilhafter Weise eine Speicherkarte geschaffen, die hin¬ sichtlich der Ausgabe ihres Speicherinhalteε autark ist; der Schallwandler als integraler Bestandteil der Speicherkarte ermöglicht nämlich eine ortsunabhängige Ausgabe der gespei- cherten und/oder aufbereiteten Daten in Form akustischer Signale (z. B. Melodien oder Sprache).This object is achieved according to the invention in the case of an electronic memory card of the type mentioned at the outset in that at least one sound transducer converts data read out of the memory into acoustic signals which immediately indicate the memory content to the card user. This advantageously creates a memory card which is self-sufficient with regard to the output of its memory content; the sound transducer, as an integral part of the memory card, enables location-independent output of the stored and / or processed data in the form of acoustic signals (eg melodies or speech).
Eine vorteilhafte Weiterbildung der erfindungsgemäßen Spei¬ cherkarte sieht vor, daß der Kartenkörper einen Resonator zur Schallerzeugung bildet. Bei dieser Ausgestaltung ist derAn advantageous development of the memory card according to the invention provides that the card body forms a resonator for sound generation. In this configuration, the
Kartenkörper in vorteilhafter Weise nicht nur Träger für die übrigen Bestandteile und Elemente der Speicherkarte, sondern dient in Doppelfunktion auch als schallverstärkender Resona¬ tor.Card body advantageously not only supports for the other components and elements of the memory card, but also serves as a sound-amplifying resonator in a double function.
Eine besonders robuste, kompakte und störunanfällige Ausge¬ staltung der erfindungsgemäßen Speicherkarte sieht vor, daß der Schallwandler ein auf dem Kartenkörper angeordneter pie¬ zoelektrischer Schwinger ist. Piezoschwinger sind vergleichs¬ weise preiswert und erlauben bei kleinster Bauform eine aus¬ reichende Schwingungsanregung des Kartenkörpers.A particularly robust, compact and failure-prone design of the memory card according to the invention provides that the sound transducer is a piezoelectric oscillator arranged on the card body. Piezo oscillators are comparatively inexpensive and, with the smallest design, permit sufficient vibration excitation of the card body.
Eine besonders komfortable akustische Ausgabe der gespeicher¬ ten und/oder aufbereiteten Daten läßt sich gemäß einer vor¬ teilhaften Ausgestaltung der Erfindung durch einen Sprachge¬ nerator realisieren, der die Daten in Sprachsignale umwandelt und den Schallwandler zur Sprachausgabe ansteuert.A particularly comfortable acoustic output of the stored and / or processed data can be realized according to an advantageous embodiment of the invention by a speech generator which converts the data into speech signals and controls the sound converter for speech output.
Das Anwendungsgebiet der erfindungsgemäßen Speicherkarte wird nach einer vorteilhaften Fortbildung der Erfindung durch eine Schnittstelle erweitert, über die Daten in das Halbleiterbau- element einschreibbar und/oder gespeicherte Daten veränderbar sind.According to an advantageous further development of the invention, the field of application of the memory card according to the invention is expanded by an interface via which data can be written into the semiconductor component and / or stored data can be changed.
Grundsätzlich kann die Speicherkarte zur Energieversorgung mit einer Batterie oder einem wiederaufladbaren Akkumulator ausgestattet sein. Das Bauvolumen der Speicherkarte und der Materialaufwand können vorteilhafterweise dadurch reduziert werden, daß die Speicherkarte eine Energiegewinnungseinrich¬ tung aufweist, die zumindest die zur Schallerzeugung erfor¬ derliche Energie bereitstellt. Besonders bevorzugt wird dazu ein Piezoelement eingesetzt, das bei mechanischer Kompression aufgrund des piezoelektrischen Effekts eine vergleichsweise hohe Ausgangsspannung zur Verfügung stellt. Diese Ausgangs¬ spannung kann unmittelbar oder auch über einen zwischenge¬ schalteten Energiespeicher zur Energieversorgung des Schal1- wandlers und ggf. weiterer Elemente der elektrischen Spei¬ cherkarte dienen.In principle, the memory card can be equipped with a battery or a rechargeable battery for energy supply. The volume of the memory card and the cost of materials can advantageously be reduced in that the memory card has an energy recovery device which provides at least the energy required for sound generation. A piezo element is particularly preferably used for this purpose, which provides a comparatively high output voltage in mechanical compression due to the piezoelectric effect. This output voltage can be used directly or also via an interposed energy store for the energy supply of the sound converter and possibly other elements of the electrical memory card.
Die Erfindung wird nachfolgend anhand eines figürlich darge¬ stellten Ausführungsbeispiels weiter erläutert; es zeigen: Figur 1 eine erfindungsgemäße Speicherkarte in Aufsicht und Figur 2 die Bedienung der Speicherkarte in Seitenansicht. Die in Figur 1 unter teilweiser Freilegung in tieferen Schichten angeordneter Bestandteile gezeigte Speicherkarte (Chipkarte) enthält ein Halbleiterbauelement 1 (Halbleiter¬ chip) , das in Figur 1 schematisch getrennt dargestellte Einheiten in Form eines Speicherbausteines 2 und einerThe invention is explained in more detail below on the basis of an exemplary embodiment shown in the figures; 1 shows a memory card according to the invention in supervision and FIG. 2 shows the operation of the memory card in a side view. The memory card (chip card) shown in FIG. 1 with partial exposure of deeper layers of components contains a semiconductor component 1 (semiconductor chip), which is shown schematically separately in FIG. 1 in the form of a memory module 2 and one
Steuereinheit 3 umfaßt. Das Halbleiterbauelement 1 ist von einem Kartenkörper '5 getragen und über Leiterbahnen 6 kontaktierbar, die auf der Oberseite 8 der Speicherkarte en¬ den. Die Leiterbahnen 6 können in der tatsächlichen prakti- sehen Ausführung über Bonddrähte unmittelbar mit dem auf de¬ ren Unterseite angeordneten Halbleiterbauelement 1 verbunden sein, wie dies beispielsweise in der eingangs genannten EP- Bl-0 254 640 ausführlich dargestellt ist. Die Leiterbahnen 6 bilden eine Schnittstelle 10 zur externen Kontaktierung der Speicherkarte. Über die Schnittstelle 10 können durch ent¬ sprechende Beaufschlagung der Steuereinheit 3 in dem Speicher 2 gespeicherte Daten gelesen, verändert oder in den Speicher 2 Daten neu eingeschrieben werden. Das Halbleiterbauelement 1 wird von einer schematisch angedeuteten Spannungsquelle 12 mit Energie versorgt, die aufgrund des außerordentlich geringen Energiebedarfs von Halbleiterbauelementen sehr leistungsschwach und damit kleinbauend sein kann.Control unit 3 comprises. The semiconductor device 1 is carried by a card body '5 and contactable via conductor tracks 6, which en¬ on the upper side 8 of the memory card. In the actual practical embodiment, the conductor tracks 6 can be connected directly to the semiconductor component 1 arranged on their underside via bonding wires, as is shown in detail, for example, in EP-B1-0254 640 mentioned at the beginning. The conductor tracks 6 form an interface 10 for external contacting of the memory card. Data stored in the memory 2 can be read, changed or data can be rewritten into the memory 2 via the interface 10 by appropriately loading the control unit 3. The semiconductor component 1 is supplied with energy by a schematically indicated voltage source 12, which, owing to the extraordinarily low energy requirement of semiconductor components, can be very poor in performance and thus small in size.
Der Steuereinheit 3 ist ein Sprachgenerator 14 nachgeordnet, der aus dem Speicher 2 ausgelesene und bedarfsweise in der Steuereinheit 3 aufbereitete Daten D in Sprachsignale 16 um¬ wandelt. Der Sprachgenerator 14 beaufschlagt zwei Schallwand¬ ler 20, 21, die als piezeoelektrische Schwinger ausgebildet und fest mit dem Kartenkörper 5 verbunden sind. Bei Anregung der Schallwandler 20, 21 wird der Kartenkörper gemäß denDownstream of the control unit 3 is a speech generator 14, which converts data D read from the memory 2 and, if necessary, processed in the control unit 3 into speech signals 16. The speech generator 14 acts on two sound transducers 20, 21, which are designed as piezoelectric vibrators and are fixedly connected to the card body 5. Upon excitation of the sound transducers 20, 21, the card body according to the
Sprach-Ausgangssignalen 16 in mechanische Schwingungen ver¬ setzt und verstärkt dabei als Resonator die von den Schall¬ wandlern erzeugten Schwingungen. Die Sprachsignale 16 erzeu¬ gen Schwingungen im menschlichen Hörbereich, so daß im Zusam- menwirken mit dem Kartenkörper 5 als Resonator deutlich hör¬ bare akustische Signale bzw. Sprachsignale ausgebbar sind. Zur Aktivierung der akustischen Signalausgabe kann durch äu¬ ßeren mechanischen Druck auf die Speicherkarte ein TastSchal¬ ter 22 geschlossen und damit der Sprachgenerator 14 aktiviert werden. In einer besonders bevorzugten Ausgestaltung der Er- findung ist die Speicherkarte mit einer Energiegewinnungsein¬ richtung 25 versehen, die als Piezoelement ausgebildet ist. Wie in Figur 1 schematisch angedeutet, wird unter Ausnutzung des piezoelektrischen Effekts bei mechanischer Kompression des Piezoelements 25 in Pfeilrichtung A eine AusgangsSpannung V generiert, die bedarfsweise unter Zwischenschaltung nicht gezeigter Glättungseinrichtungen oder Energiespeicher den Sprachgenerator 14 versorgt.Speech output signals 16 are set into mechanical vibrations and, as a resonator, amplify the vibrations generated by the sound transducers. The speech signals 16 generate vibrations in the human hearing range, so that in cooperation with the card body 5 as a resonator, clearly audible acoustic signals or speech signals can be output. To activate the acoustic signal output, a pushbutton switch 22 can be closed by external mechanical pressure on the memory card, and thus the speech generator 14 can be activated. In a particularly preferred embodiment of the invention, the memory card is provided with an energy recovery device 25 which is designed as a piezo element. As indicated schematically in FIG. 1, using the piezoelectric effect with mechanical compression of the piezo element 25 in the direction of arrow A, an output voltage V is generated which, if necessary, supplies the speech generator 14 with the interposition of smoothing devices or energy stores, not shown.
Figur 2 zeigt in stark übertriebener Darstellung die mechani- sehe Schwingung des Kartenkörpers 5 bei elektrischer Anregung der piezoelektrischen Schwinger 20, 21 durch das andeutungs¬ weise gezeigte Pressen des Kartenkörpers 5 im Bereich des Piezoelements 25.FIG. 2 shows in a greatly exaggerated representation the mechanical oscillation of the card body 5 when the piezoelectric vibrators 20, 21 are excited electrically by the pressing of the card body 5, which is indicated, in the region of the piezo element 25.

Zur akustischen Ausgabe wird beim Ak¬ tivieren des Sprachgenerators 14 dieser Wert "007" von der Steuereinrichtung 3 ausgelesen, bedarfsweise aufbereitet (beispielsweise in die einzelnen Ziffern 0-0-7 zerlegt) und in Form zur Ansteuerung des Sprachgenerators 14 geeigneterValue "007" saved. For the acoustic output, when the speech generator 14 is activated, this value "007" is read out by the control device 3, processed if necessary (broken down, for example, into the individual digits 0-0-7) and in the form more suitable for controlling the speech generator 14

Der Sprachgenerator 14 wird von dem Piezoelement 25 mit ausreichender Energie versorgt, um gemäß den Daten D Sprachsignale 16 zu erzeugen und über diese die piezoelektrischen Schwinger 20, 21 anzuregen. Auf- grund der Resonatorwirkung des Kartenkörpers 5 (Figur 2) ist in diesem Fall deutlich die symbolisierte Sprachausgabe 30 "NULL-NU L-SIEBEN" zu hören.Data D forwarded to this. The speech generator 14 is supplied with sufficient energy by the piezo element 25 to generate speech signals 16 according to the data D and to excite the piezoelectric oscillators 20, 21 via them. In this case, due to the resonator effect of the card body 5 (FIG. 2), the symbolized voice output 30 "ZERO-NULL-SEVEN" can be heard.
Die erfindungsgemäße Speicherkarte ermöglicht damit, den Be- nutzer ortsunabhängig und ohne externe Auslesevorrichtungen über den Speicherinhalt zu informieren. Der Speicher kann fest gespeicherte Informationen oder Melodien enthalten und über die Schnittstelle 10 auch mit temporär einlesbaren Informationen beaufschlagt werden. Die Speicherkarte ist durch Verwendung eines Schallwandlers und insbesondere der piezoelektrischen Schwinger trotz dieser zusätzlichen Leistungseigenschaft ausgesprochen kompakt und in dem übli¬ chen Chipkartenformat realisierbar. The memory card according to the invention thus enables the user to be informed about the memory content regardless of location and without external readout devices. The memory can contain permanently stored information or melodies via the interface 10 can also be loaded with temporarily readable information. In spite of this additional performance characteristic, the memory card is extremely compact and can be implemented in the usual chip card format by using a sound transducer and in particular the piezoelectric transducer.
