Mobilfunkgerätmobile device

Die vorliegende Erfindung betrifft ein Mobilfunkgerät mitThe present invention relates to a mobile radio device

Tastatur, Display, Mikrofon, Lautsprecher und einer im Mobil- funkgerätegehäuse angeordneten Leiterplatte, auf der elektronische Bauelemente des Mobilfunkgerätes angeordnet sind.Keyboard, display, microphone, loudspeaker and a circuit board arranged in the mobile radio device housing, on which electronic components of the mobile radio device are arranged.

Bei den bekannten Mobilfunkgeräten ist der Lautsprecher auf der oberen Seite des Mobilfunkgerätegehäuses zwischen dem Display und dem hinteren Rand des Mobilfunkgerätegehäuses angeordnet. Damit geht in die Gesamtlänge des Mobilfunkgerätes mindestens der Durchmesser des Lautsprechers ein.In the known mobile radio devices, the loudspeaker is arranged on the upper side of the mobile radio device housing between the display and the rear edge of the mobile radio device housing. This means that at least the diameter of the loudspeaker is included in the overall length of the mobile radio device.

Die Anforderungen des Marktes an Mobilfunkgeräte sind in der heutigen Zeit aber dadurch gekennzeichnet, dass eine fortschreitende Miniaturisierung des Mobilfunkgerätes bei gleichbleibender bzw. verbesserter Leistung gefordert wird. Spe- ziell bei den akustischen Komponenten ist die Miniaturisierung aufgrund der Funktionalität und der physikalischen Gesetzmäßigkeiten häufig nicht ohne Leistungseinbußen möglich.However, the requirements of the market for mobile radio devices are characterized today by the fact that progressive miniaturization of the mobile radio device is required with the same or improved performance. In the case of acoustic components in particular, miniaturization is often not possible without sacrificing performance due to the functionality and the physical laws.

Aufgabe der vorliegenden Erfindung ist es nun, ein Mobilfunk- gerät der eingangs genannten Art anzugeben, bei welchem die Länge deutlich verringert ist, aber gleichzeitig keine Leistungseinbuße bei dem eingebauten Lautsprecher gegeben ist.The object of the present invention is now to provide a mobile radio device of the type mentioned at the beginning, in which the length is significantly reduced, but at the same time there is no loss of performance in the built-in loudspeaker.

Diese Aufgabe wird für das eingangs genannte Mobilfunkgerät erfindungsgemäß dadurch gelöst, dass der Lautsprecher teilweise unterhalb des Displays angeordnet ist. Dadurch ergibt sich eine deutliche Langenreduzierung des Mobilfunkgerates, ohne dass die Leistungsfähigkeit des Lautsprechers negativ beeinflusst wird.This object is achieved according to the invention for the mobile radio device mentioned at the outset in that the loudspeaker is arranged partially below the display. This results in a significant reduction in the length of the mobile radio device, without having a negative impact on the performance of the loudspeaker.

Eine zweckmäßige Ausgestaltung des erfindungsgemaßen Mobilfunkger tes ist dadurch gekennzeichnet, dass die Leiterplatte an ihrem hinteren Ende, an dem das Display angeordnet ist, eine Ausnehmung aufweist, in welche der Lautsprecher einschiebbar ist. Auf diese Weise ergibt sich eine einfache Be- festigung des Lautsprechers auf der Leiterplatte des Mobilfunkgerates .An expedient embodiment of the mobile radio device according to the invention is characterized in that the circuit board has at its rear end, on which the display is arranged, a recess into which the loudspeaker can be inserted. In this way, the loudspeaker is simply attached to the circuit board of the mobile radio device.

Weitere zweckmäßige Ausgestaltungen des erfindungsgemaßen Mobilfunkgerates ergeben sich aus den weiteren Unteranspruchen sowie aus der nachfolgenden Beschreibung eines Ausfuhrungsbeispiels anhand der Zeichnung.Further expedient refinements of the mobile radio device according to the invention result from the further subclaims and from the following description of an exemplary embodiment with reference to the drawing.

Es zeigenShow it

Figur 1 eine teilweise Seitenansicht der bestuckten Leiterplatte eines Mobilfunkgerates gemäß der vorliegenden Erfindung, und1 shows a partial side view of the printed circuit board of a mobile radio device according to the present invention, and

Figur 2 eine teilweise perspektivische Ansicht von unten auf die in Figur 1 dargestellte Leiterplatte.Figure 2 is a partial perspective view from below of the circuit board shown in Figure 1.

Die Zeichnung zeigt die Leiterplatte L mit dem Display D, welches in einem auf der Leiterplatte L befestigten Blechrahmen eingerastet ist.The drawing shows the circuit board L with the display D, which is locked in a sheet metal frame attached to the circuit board L.

Die Leiterplatte L weist an ihrem hinteren Ende, an welchem auch das Display D angeordnet ist, eine Ausnehmung auf, in welche der Lautsprecher R einschiebbar ist. Zur besseren Fuhrung besitzt der eigentliche Lautsprecher eine Halterung, welche an zwei gegenüberliegenden Seiten U- formige Schienen S aufweist. Mittels dieser Schienen S wird der Lautsprecher in der Ausnehmung der Leiterplatte L gefuhrt und gehalten.At its rear end, on which the display D is also arranged, the printed circuit board L has a recess into which the loudspeaker R can be inserted. For better guidance, the actual loudspeaker has a holder which has U-shaped rails S on two opposite sides. The loudspeaker is guided and held in the recess of the printed circuit board L by means of these rails S.

Dadurch, dass der Lautsprecher zum Teil unterhalb des Displays D angeordnet ist, ergibt sich eine Langenreduzierung d die bis zur Hälfte des Lautsprecherdurchmessers betragen kann, wobei die Leistungsfähigkeit des Lautsprechers nicht negativ beeinflusst wird.The fact that the loudspeaker is partially arranged below the display D results in a length reduction d which can be up to half the loudspeaker diameter, the performance of the loudspeaker not being negatively influenced.

Dadurch kann entweder die gesamte Lange des Mobilfunkgerates verkürzt werden oder es können bei konstanten Außenabmessungen des Mobilfunkgerates andere Komponenten, wie z. B. das Display D, verlängert werden.As a result, either the entire length of the mobile device can be shortened, or other components, such as, for. B. the display D, can be extended.

Durch die Ausnehmung in der Leiterplatte L und die Nutzung des dadurch frei gewordenen Bauraums kann zusatzlich die Gesamtdicke des Mobilfunkgerates gering gehalten werden.Due to the recess in the printed circuit board L and the use of the installation space thus freed up, the overall thickness of the mobile radio device can additionally be kept low.

Zwischen dem eigentlichen Lautsprecher und den Schallaus- trittsoffnungen in der Gehausewand kann in geeigneter Weise ein Schallkanal vorgesehen werden. A sound channel can be provided in a suitable manner between the actual loudspeaker and the sound outlet openings in the wall of the housing.
