Einbau-Vorrichtung für ein mobiles EndgerätInstallation device for a mobile device
Die Erfindung bezieht sich auf eine Vorrichtung zum Einbau in ein mobiles Endgerät, mit einer Akkumulatoreinheit zur Stromversorgung des Endgerätes .The invention relates to a device for installation in a mobile terminal, with an accumulator unit for supplying power to the terminal.
Eine typische Vorrichtung zum Einbau in ein mobiles Endgerät, wie insbesondere Mobiltelefone und andere mobile Kommunikationsendgeräte, ist die Akkumulatoreinheit. Diese kann in Form eines Akkumulatorblocks oder mehrerer Akkumulatorzellen vorliegen. Im Sprachgebrauch dieser Beschreibung ist somit ein Akkumulatorblock eine Vorrichtung zum Einbau in ein mobiles Endgerät, wobei alternativ die Akkumulatoreinheit aus mehreren Akkumulatorzellen zusammengesetzt sein kann.A typical device for installation in a mobile terminal, such as in particular mobile telephones and other mobile communication terminals, is the accumulator unit. This can be in the form of an accumulator block or several accumulator cells. In the parlance of this description, an accumulator block is thus a device for installation in a mobile terminal, wherein the accumulator unit can alternatively be composed of several accumulator cells.
Des weiteren gibt es gerade auch bei Mobiltelefonen das Bestreben, im Wege einer Nachrüstung gewünschte Leistungsmerkmale zu verbessern.In addition, there is a desire, particularly in the case of mobile telephones, to improve the desired features by retrofitting.
Zu diesen Leistungsmerkmalen gehört insbesondere auch eine Wiedergabequalität von SchallSignalen. In diesem Zusammenhang ist es, ohne dass eine Nachrüstungsmöglichkeit besteht, bereits bekannt, beispielsweise bei Mobiltelefonen ein vorgesehenes Anzeigeschutzfenster als sog. " „Biegewellenlautsprecher" auszuführen, wobei eine Anregung des Anzeigeschutzfensters mit BiegeSchwingungen üblicher Weise über mindestens einen Piezo-Aktuator erfolgt.These performance features include, in particular, a reproduction quality of sound signals. In this context, it is already known, without the possibility of retrofitting, to design, for example in the case of mobile telephones, an intended display protection window as a so-called "bending wave loudspeaker", the display protection window being excited with bending vibrations in the usual way via at least one piezo actuator.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, bei mobilen Endgeräten die Möglichkeit zu schaffen, im Wege einer Nachrüstung eine verbesserte akustische Wiedergabequalität zu schaffen. Diese Aufgabe wird bei der eingangs genannten Vorrichtung dadurch gelöst, dass die Vorrichtung ein Gehäuse aufweist, in dem die Akkumulatoreinheit untergebracht ist, das Gehäuse eine im wesentlichen ebene Seitenfläche aufweist, die als Biegewellenlautsprecher ausgebildet ist, und in dem Gehäuse ein Aktuator zur Anregung der Seitenfläche mit Biegeschwingungen, eine mittels der Akkumulatoreinheit mit Energie versorgte Steuerungselektronik für den Aktuator und eine Kontaktiereinrichtung für die Steuerungselektronik untergebracht sind.Proceeding from this, the present invention seeks to provide mobile terminals with the possibility of retrofitting to improve acoustic reproduction quality. This object is achieved in the device mentioned at the outset in that the device has a housing in which the accumulator unit is accommodated, the housing has an essentially flat side surface which is designed as a flexible shaft loudspeaker, and an actuator in the housing for exciting the side surface with bending vibrations, a control electronics supplied with energy by means of the accumulator unit for the actuator and a contacting device for the control electronics.
Die Erfindung geht somit davon aus, dass die neue Vorrichtung zum Einbau in ein mobiles Endgerät zum Ersetzen eines bei handelsüblichen mobilen Endgeräten bereits vorhandenen Einbaumoduls ausgebildet ist. Dazu kommt insbesondere der für die Stromversorgung maßgebliche Akkumulatorblock eines mobilen Endgeräts in Frage, der durch die neue Vorrichtung ersetzt werden kann. Auf diese Weise lässt sich durch Austausch des Akkumulatorblocks eine verbesserte Schallwiedergabequalität des mobilen Endgeräts erzielen, sofern das mobile Endgerät über erforderlicheThe invention is therefore based on the fact that the new device is designed for installation in a mobile terminal for replacing an installation module already present in commercially available mobile terminals. In addition, the battery block of a mobile terminal device, which is decisive for the power supply, can be used, which can be replaced by the new device. In this way, an improved sound reproduction quality of the mobile terminal can be achieved by exchanging the accumulator block, provided that the mobile terminal has more than required
Kontaktelemente, die mit der Kontaktiereinrichtung im Gehäuse zusammen wirken, verfügt.Contact elements that interact with the contacting device in the housing has.
Aus Platzgründen wird die Vorrichtung ähnlich einem handelsüblichen Akkumulatorblock im wesentlichen blockförmig sein, wobei dann die eine Außenfläche des mobilen Endgeräts bildende Seitenfläche des Gehäuses der Vorrichtung als Biegwellenlautsprecher betrieben wird.For reasons of space, the device will be essentially block-shaped, similar to a commercially available accumulator block, the side surface of the housing of the device forming an outer surface of the mobile terminal then being operated as a flexible-wave loudspeaker.
Bevorzugt kann die als Biegewellenlautsprecher wirkende Seitenfläche des Gehäuses als einrastbarer Deckel ausgeführt sein, wobei der übrige Teil des Gehäuses im wesentlichen die Form einer Schale aufweist, in der die Akkumulatoreinheit, die Kontaktiereinrichtung und die Steuerungselektronik untergebracht sind. Der einrastbare Deckel wird bei diesem Ausführungsbeispiel als Biegewellenlautsprecher betrieben, wobei der Aktuator auf einer in bezug auf das mobile Endgerät innen liegenden Deckelseite angebracht ist.The side surface of the housing acting as a flexible shaft loudspeaker can preferably be designed as a snap-on cover, the remaining part of the housing essentially having the shape of a shell in which the battery unit, the contacting device and the control electronics are accommodated. In this embodiment, the snap-on cover is operated as a flexible shaft loudspeaker, wherein the actuator is mounted on a cover side located inside with respect to the mobile terminal.
Bei einem bevorzugten Ausführungsbeispiel ist der Aktuator im Bereich eines Zentrums der als Biegewellenlautsprecher wirkenden Seitenfläche des Gehäuses angeordnet, wobei die Akkumulatoreinheit an die Anordnung des Aktuators angepasst ist . In dieser Weise ist der Aktuator für eine Schallabstrahlung über die zu Biegeschwingungen angeregte Seitenfläche des Gehäuses besonders günstig angeordnet. Dabei kann die Akkumulatoreinheit von ihrer Form und Anordnung her an die Anordnung des Aktuators angepasst sein, so dass diesem genügend Raum zur Verfügung steht . Bei besonders platzsparenden Bauweisen kann der Aktuator seitlich von der Akkumulatoreinheit positioniert sein.In a preferred exemplary embodiment, the actuator is arranged in the region of a center of the side face of the housing acting as a flexible shaft loudspeaker, the accumulator unit being adapted to the arrangement of the actuator. In this way, the actuator for sound radiation via the side surface of the housing excited to bending vibrations is arranged particularly favorably. The shape and arrangement of the accumulator unit can be adapted to the arrangement of the actuator, so that it has enough space available. In the case of particularly space-saving designs, the actuator can be positioned on the side of the accumulator unit.
Das Material für die als Biegewellenlautsprecher wirkende Seitenfläche des Gehäuses kann von dem restlichen Gehäusematerial abweichen, insbesondere für eine Wiedergabe akustischer Signale optimiert sein. Da die Akkumulatoreinheit durch das gemeinsame Gehäuse der Vorrichtung ausreichend mechanisch geschützt ist, kann insbesondere bei der Ausführungsform, bei dem die als Biegewellenlautsprecher wirkende Seitenfläche als einrastbarer Deckel ausgeführt ist, ein weniger steifes Material für den Deckel eingesetzt werden, dass für eine Anregung mit Biegeschwingungen optimiert ist .The material for the side surface of the housing acting as a flexible shaft loudspeaker can deviate from the rest of the housing material, in particular it can be optimized for the reproduction of acoustic signals. Since the accumulator unit is adequately mechanically protected by the common housing of the device, a less rigid material can be used for the cover, in particular in the embodiment in which the side surface acting as a flexible shaft loudspeaker is designed as a snap-in cover, which material is optimized for excitation with bending vibrations is.
Die oben genannte Aufgabe wird hinsichtlich des mobilen Endgerätes gelöst durch die Merkmale des Anspruchs 5.The above-mentioned object is achieved with regard to the mobile terminal by the features of claim 5.
Die Erfindung wird nachfolgend beispielshalber anhand einer Zeichnung noch näher erläutert. Die einzige Figur zeigt eine Vorrichtung zum Einbau in ein mobiles Endgerät, mit einem Gehäuse, dessen eine Seitenfläche als Biegewellenlautsprecher betrieben wird. Die in der Figur gezeigte Vorrichtung zum Einbau in ein mobiles Endgerät weist ein im wesentlichen schalenförmiges Gehäuseteil 1 auf. In dem Gehäuseteil 1 ist eine Akkumulatoreinheit 2, eine Kontaktiereinrichtung 3 und eine Steuerungselektronik 4 untergebracht . Dabei dient dieThe invention is explained in more detail below by way of example with reference to a drawing. The single figure shows a device for installation in a mobile terminal, with a housing, one side surface of which is operated as a flexible shaft loudspeaker. The device shown in the figure for installation in a mobile terminal has an essentially shell-shaped housing part 1. Accumulator unit 2, contacting device 3 and control electronics 4 are accommodated in housing part 1. The serves
Akkumulatoreinheit 2, die hier blockförmig ausgebildet ist, zur Stromversorgung des mobilen Endgerätes, insbesondere auch der Steuerungselektronik 4.Accumulator unit 2, which is block-shaped here, for supplying power to the mobile terminal, in particular also to the control electronics 4.
Die Kontaktiereinrichtung 3 steht im eingebauten Zustand der Vorrichtung in Verbindung mit zugehörigen Kontaktelementen des mobilen Endgerätes, an denen in Schallsignale umzusetzende elektrische Signale anliegen.In the installed state of the device, the contacting device 3 is connected to associated contact elements of the mobile terminal, against which electrical signals to be converted into sound signals are present.
Die Steuerungselektronik 4 bereitet die von derThe control electronics 4 prepares the
Kontaktiereinrichtung 3 kommenden elektrischen Signale derart auf, dass sie über einen Piezo-Aktuator 5, der von der Steuerungselektronik 4 gesteuert wird, zur Anregung eines im wesentlichen ebenen Gehäusedeckels 6 mit Biegeschwingungen umgesetzt werden.Contacting device 3 arrives electrical signals in such a way that they are implemented with bending vibrations via a piezo actuator 5, which is controlled by the control electronics 4, to excite an essentially flat housing cover 6.
Der Gehäusedeckel 6 wird somit als Biegewellenlautsprecher betrieben, wobei sein Material für diesen Zweck optimiert sein kann, insbesondere von dem Material für die Gehäuseschale 1 abweichen kann. Die Gehäuseschale 1 und der Gehäusedeckel 6 bilden somit ein geschlossenes Gehäuse, in dem die Akkumulatoreinheit 2, die Kontaktiereinrichtung 3, die Steuerungselektronik 4 und der Piezo-Aktuator 5 aufgenommen sind. Dieses Gehäuse kann bei geeigneter Wahl seiner Abmessungen ohne weiteres als Einbaumodul anstelle eines Standard-Akkumulatorblocks eines betreffenden mobilen Endgerätes verwendet werden.The housing cover 6 is thus operated as a flexible shaft loudspeaker, and its material can be optimized for this purpose, in particular can differ from the material for the housing shell 1. The housing shell 1 and the housing cover 6 thus form a closed housing in which the accumulator unit 2, the contacting device 3, the control electronics 4 and the piezo actuator 5 are accommodated. With a suitable choice of its dimensions, this housing can easily be used as a built-in module instead of a standard accumulator block of a relevant mobile terminal.
Der Gehäusedeckel 6 steht seitlich über Ränder der Gehäuseschale 1 vor und ist möglichst groß bemessen, um eine günstige Schallwiedergabequalität zu ermöglichen. Der Gehäusedeckel 6 kann entweder mit der Gehäuseschale 1 oder mit einem Gehäuse eines mobilen Endgerätes verrastet sein, in das die Vorrichtung eingebaut wird.The housing cover 6 protrudes laterally over the edges of the housing shell 1 and is dimensioned as large as possible in order to enable a favorable sound reproduction quality. The housing cover 6 can either be locked to the housing shell 1 or to a housing of a mobile terminal in which the device is installed.
Abweichend von dem dargestellten Ausführungsbeispiel kann der Piezo-Aktuator 5 auch im Bereich eines Zentrums des Gehäusedeckels 6 angeordnet sein, sofern die besonders viel Platz beanspruchende Akkumulatoreinheit entsprechend ausgebildet ist. Besteht die Akkumulatoreinheit 2 beispielsweise aus zwei Akkuzellen kann der freie Bereich zwischen diesen Akkuzellen zur Anordnung des Piezo-Aktuators benutzt werden.In a departure from the exemplary embodiment shown, the piezo actuator 5 can also be arranged in the region of a center of the housing cover 6, provided the accumulator unit, which takes up a particularly large amount of space, is designed accordingly. If the accumulator unit 2 consists, for example, of two accumulator cells, the free area between these accumulator cells can be used to arrange the piezo actuator.

Kontaktelemente, über die die elektrischen Signale zu der Kontaktiereinrichtung 3 und von da aus zur Steuerungselektronik 4 übertragen werden.Contact elements via which the electrical signals are transmitted to the contacting device 3 and from there to the control electronics 4.
Die eng benachbarte Anordnung der Steuerungselektronik 4 und des Piezo-Aktuators 5 ermöglicht eine besonders günstige Anpassung, wobei insbesondere ein Inertialbetrieb des Piezo- Aktuators möglich ist. The closely adjacent arrangement of the control electronics 4 and the piezo actuator 5 enables a particularly favorable adaptation, in particular an inertial operation of the piezo actuator is possible.
