Abstract
Description
Die Erfindung bezieht sich auf eine Uhr, insbesondere eine Armbanduhr, mit einem Gehäuse, dessen Gehäuseinnenraum beobachterseitig eine durch ein Deckglas verschlossene Öffnung und bodenseitig eine Schallöffnung besitzt, die durch eine Membran verschlossen ist, welche mit ihrem radial umlaufenden Randbereich dicht an einer entsprechenden Ringfläche des Gehäuses in Anlage ist, mit einem in dem Gehäuseinnenraum angeordneten Schwingungserzeuger, durch den Tonschwingungen erzeugbar sind.The invention relates to a clock, in particular a wristwatch, with a housing whose housing interior observer has an opening closed by a cover glass and the bottom side has a sound opening which is closed by a membrane, which with its radially peripheral edge region close to a corresponding annular surface of the Housing is in Appendix, with a arranged in the housing interior vibrator, can be generated by the sound vibrations.
Bei derartigen Uhren sorgt die Membran dafür, daß der Gehäuseinnenraum, in dem sich das Uhrwerk und der Schwingungserzeuger befinden, nach außen verschlossen ist, um ein Eindringen von Schmutz und Feuchtigkeit zu verhindern.In such watches, the membrane ensures that the housing interior, in which the movement and the vibrator are located, is closed to the outside to prevent ingress of dirt and moisture.
Gleichzeitig soll durch die Schwingungsfähigkeit der Membran eine gute Übertragung der von dem Schwingungserzeuger erzeugten Tonschwingungen nach außen gewährleistet werden.At the same time a good transmission of the sound vibrations generated by the vibrator to be ensured by the vibration of the membrane to the outside.
Diese Übertragung der Tonschwingungen nach außen erfolgt aber nur dann optimal, wenn die Frequenz der von dem Schwingungserzeuger erzeugten Tonschwingungen und die Eigenfrequenz der Membran gleich sind.However, this transmission of the sound vibrations to the outside is optimal only if the frequency of the sound vibrations generated by the vibration generator and the natural frequency of the membrane are the same.
Aufgabe der Erfindung ist es daher eine Uhr der eingangs genannten Art zu schaffen, bei der eine optimierte Übertragung der Tonschwingungen des Schwingungserzeugers nach außen erfolgt.The object of the invention is therefore to provide a clock of the type mentioned, in which there is an optimized transmission of the sound vibrations of the vibrator to the outside.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der radial umlaufende Rand der Membran von einer Zugeinrichtung radial nach außen zugbelastbar ist.This object is achieved in that the radially encircling edge of the membrane of a pulling device is radially outwardly zugbelastbar.
Durch diese Ausbildung ist es möglich die Spannung der Membran zu verändern und damit die Eigenfrequenz der Membran auf die Frequenz der von dem Schwingungserzeuger erzeugten Tonschwingungen einzustellen. Damit können diese Tonschwingungen optimiert aus dem Gehäuseinnenraum nach außen übertragen werden, so daß eine Brillianz der erzeugten Tonschwingungen weitesgehend keine Beeinträchtigung bei der Übertragung nach außen erleidet.By this design, it is possible to change the voltage of the membrane and thus adjust the natural frequency of the membrane to the frequency of the sound vibrations generated by the vibrator. Thus, these sound vibrations can be optimally transmitted out of the housing interior to the outside, so that a brilliance of the generated sound vibrations largely suffers no impairment in the transmission to the outside.
Toleranzbedingte Schwankungen der Tonschwingungen des Schwingungserzeugers sind ebenfalls ausgleichbar.Tolerance-related fluctuations in the sound vibrations of the vibrator are also compensated.
Eine Zugbelastung ist auf einfache Weise möglich, wenn der radial umlaufende Rand der Membran dicht mit einem Spannring verbunden ist, der durch die Zugeinrichtung radial nach außen zugbelastbar ist, wobei vorzugsweise der radial umlaufende Rand der Membran durch eine nichtlösbare Verbindung mit dem Spannring verbunden ist..A tensile load is possible in a simple manner when the radially encircling edge of the membrane is tightly connected to a clamping ring, which can be tensioned radially outwardly by the pulling device, wherein preferably the radially encircling edge of the membrane is connected by a non-detachable connection with the clamping ring. ,
Ist die Membran unter einer bestimmten radialen Vorspannung mit dem Spannring verbunden, so kann zunächst die Membran einfach mit einer bestimmten Grundspannung und somit einer bestimmten Eigenfrequenz mit dem Spannring verbunden werden, ehe dann durch die Zugeinrichtung eine Feineinstellung erfolgt.If the membrane is connected to the clamping ring under a certain radial pretension, the membrane can first be connected to the clamping ring with a certain basic tension and thus a certain natural frequency, before a fine adjustment is then made by the pulling device.
Eine dichte und feste Verbindung der Membran mit dem Spannring ist dadurch möglich, daß die Membran durch Löten oder Schweißen, insbesondere durch Laserschweißen mit dem Spannring verbunden ist.A tight and firm connection of the membrane with the clamping ring is possible in that the membrane is connected by soldering or welding, in particular by laser welding with the clamping ring.
Dabei besitzt das Laserschweißen den zusätzlichen Vorteil, daß eine Wärmebelastung nur im unmittelbaren Schweißbereich nicht aber in dem die Eigenfrequenz bestimmenden frei gespannten Bereich der Membran erfolgt. Eine wärmebedingte Veränderung der Eigenfrequenz der Membran wird so vermieden.In this case, the laser welding has the additional advantage that a heat load only in the immediate welding area but not in the natural frequency-determining free-stretched area of the membrane he follows. A heat-related change in the natural frequency of the membrane is thus avoided.
Eine andere dichte und feste Verbindung der Membran mit dem Spannring unter Vermeidung einer Wärmebeeinflußung der Membran besteht darin, daß die Membran durch Kleben mit dem Spannring verbunden ist.Another dense and firm connection of the membrane with the clamping ring while avoiding heat influence of the membrane is that the membrane is adhesively bonded to the clamping ring.
Die Membran kann aber auch zwischen zwei miteinander verbindbaren Spannringteilen eingeklemmt sein, die vorzugsweise durch Schrauben axial gegeneinander spannbar sind.However, the membrane can also be clamped between two clamping ring parts which can be connected to one another, which are preferably axially tensioned against one another by means of screws.
Zur Abdichtung des Verbindungsbereichs der Membran oder des Spannrings mit dem Gehäuse kann in einer in der Ringfläche radial umlaufend ausgebildeten Nut ein Dichtring angeordnet sein, an dem die Membran oder der Spannring axial in Anlage ist.To seal the connecting region of the membrane or the clamping ring with the housing, a sealing ring may be arranged in a radially circumferentially formed groove in the annular surface, on which the membrane or the clamping ring is axially in abutment.
Zum festen Beaufschlagen der Ringfläche durch den Spannring und zu dessen Fixierung kann der Spannring mittels Spannschrauben gegen die Ringfläche spannbar sein, die in axiale Gewindebohrungen des Gehäuses einschraubbar sind und mit ihrem Schraubenkopf auf dem Spannring in Auflage sind.For tight loading of the annular surface by the clamping ring and its fixation of the clamping ring can be tensioned by means of clamping screws against the annular surface, which are screwed into axial threaded holes of the housing and with her screw head on the clamping ring in circulation.
Dabei sind zur gleichmäßigen Anlage vorzugsweise die Spannschrauben um den Spannring herum gleichmäßig verteilt angeordnet.In this case, the clamping screws are preferably evenly distributed around the clamping ring for even investment.
Die Zugeinrichtung kann darin bestehen, daß in dem Spannring radial gerichtete und radial nach außen mündende Gewindebohrungen ausgebildet sind, in die Zugschrauben einschraubbar sind, die an dem Gehäuse gegen radiale Einwärtsbewegung abstützbar sind.The pulling device may consist in that in the clamping ring radially directed and radially outwardly opening threaded bores are formed, can be screwed into the lag screws, which are supported on the housing against radial inward movement.
Damit kann eine Einstellung der Eigenfrequenz der Membran im in das Gehäuse eingebauten Zustand erfolgen, so daß einbaubedingte Veränderungen der Eigenfrequenz der Membran nicht entstehen können.Thus, an adjustment of the natural frequency of the membrane can be carried out in the built-in housing state, so that installation-related changes in the natural frequency of the membrane can not arise.
In einfacher Ausbildung sind dabei die Zugschrauben in zu den Gewindebohrungen koaxialen Stufenbohrungen angeordnet, deren große Stufe radial nach außen mündet und an deren Übergang von der großen Stufe zur kleinen Stufe die Zugschraube mit ihrem Schraubenkopf abgestützt ist.In a simple training while the lag screws are arranged in the threaded holes coaxial stepped holes, the large stage opens radially outward and at the transition from the large step to the small stage, the lag screw is supported with its screw head.
Eine weitere Möglichkeit zur Ausbildung der Zugeinrichtung besteht darin, daß die Membran in ihrem radial äußeren Randbereich durch ein Spannelement axial verstellbar beaufschlagbar ist, wobei das Spannelement ein die Membran in ihrem radial äußeren umlaufenden Randbereich axial beaufschlagender Spannring, was eine gleichmäßige radial umlaufende Beaufschlagung der Membran ermöglicht.Another possibility for forming the traction device is that the membrane in its radially outer edge region by a clamping element axially acted upon, wherein the clamping element acts on the membrane in its radially outer peripheral edge region axially Clamping ring, which allows a uniform radial circumferential loading of the membrane.
Zum einfachen Einstellen des Spannrings kann das Spannelement mittels Stellschrauben axial verstellbar sein.For easy adjustment of the clamping ring, the clamping element can be axially adjustable by means of adjusting screws.
Zum Schutz der Membran gegen Beschädigungen und gleichzeitig gutem Austreten der Tonschwingungen nach außen ist vorzugsweise die Membran von einem an dem Gehäuse befestigbaren Gehäuseboden abgedeckt, wobei zwischen Membran und Gehäuseboden ein Raum gebildet ist, von dem Schallaustrittsöffungen insbesondere radial nach außen führen.To protect the membrane against damage and at the same time good exit of the sound vibrations to the outside, the membrane is preferably covered by a housing bottom fastened to the housing, between the membrane and the housing bottom a space is formed, lead from the sound outlet openings in particular radially outward.
Zu einer deutlichen Verstärkung des nach außen abgegebenen Tons der Tonschwingungen führt es, wenn der Raum und die Schallaustrittsöffnungen einen Helmholtz-Resonator bilden.It leads to a significant amplification of the sound emitted to the outside of the sound vibrations, when the space and the sound outlet openings form a Helmholtz resonator.
Vorzugsweise ist die Membran eine Metallmembran, wobei diese möglichst aus einem korrosionsbeständigen Material, insbesondere aus Gold oder einer Goldlegierung bestehen kann.Preferably, the membrane is a metal membrane, which may possibly consist of a corrosion-resistant material, in particular of gold or a gold alloy.
Ein gutes Spektrum an Tonschwingungen ist dadurch erzielbar, daß der Schwingungserzeuger eine von einem Anschlaghammer anschlagbare Glocke oder eine Tonfeder ist, die vorzugsweise aus einem Metall besteht.A good range of sound vibrations can be achieved by virtue of the fact that the oscillator is a bell which can be hit by a stop hammer or a gong which preferably consists of a metal.
Besonders gute Klangeigenschaften sind dabei dann erreichbar, wenn der Schwingungserzeuger aus Niobium (Nb) oder einer Niobium (Nb) enthaltenen Legierung besteht.Particularly good sound properties can be achieved if the vibration generator consists of niobium (Nb) or a niobium (Nb) -containing alloy.
