## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims priority under 35 U.S.C. § 119 from International Application Number PCT/IB02/01563 filed May 8, 2002.
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a component for generating vibration effects combined with light effects. In particular, the present invention relates to a mobile terminal, especially a mobile phone, containing a component for generating vibration effects combined with light effects for alerting a user of the mobile terminal. The invention also relates to vibrational lights effects used for gaming purposes or can be used during music listening. For example in games, when something special happens, this could be shown by both light and vibration.
2. Discussion of Related Art
The alerting of a user of a mobile terminal by acoustic signals can be inconvenient since such an acoustic signal may disturb himself or other persons in the environment of the phone but also during telephone conversation, gaming, music listening and the like. Therefore, today's mobile terminals, especially mobile phones, implement a vibration signaling function to offer a user the possibility to receive a silent signaling. Alternatively, today's mobile terminals, especially mobile phones, implement an optical signaling function e.g. emitting of flashing lights, to offer a user the possibility to receive a silent signaling.

FIG. 1 shows a schematic block diagram illustrating the principle setup of a component with respect to an embodiment of the invention,
FIG. 2a shows a block diagram illustrating a vibration generator including light elements in a first operational position according to an embodiment of the invention and

BEST MODE FOR CARRYING OUT THE INVENTION
The following description relates to a component according to embodiments of the invention. Same or equal parts shown in the figures will be referred by the same reference numerals.
FIG. 1 shows a schematic block diagram illustrating the principle setup of a component with respect to an embodiment of the invention. The principle setup comprises a mass 100 and a driver 110 which drives the mass, both the mass 100 and the driver 110 representing the active parts of a vibration generating setup, a light emitter 200 and a light path 300 to an observer 400.
The mass 100 is reciprocated by the driver 110. The driving directions upwards and downwards shown in FIG. 1 by indicating arrows 101 and 102 are an example, but not limiting. The movement of the mass 100 is performed in such a manner that the movement generates vibrations excited by the driver 110. Preferably, the generated vibrations are passed on to a housing of the component and further to an electronic device containing the component or its housing, respectively. The vibrating housing can be sensed by a user.
The moving mass 100 is used to penetrate the light path 300. The moving mass covers and uncovers the light path so that an observer 400 can view the light emitter 200 during an uncovered period of time and during the covered period of time no direct light may pass to the observer 400.
The aforementioned movement of the mass penetrating preferably periodically into the light path leads to a flashing or stroboscopic light impression of the observer 400.
A window 310 may be interposed in the light path 300. This window may be a blank of a housing or may be a window 310 made of glass or translucent polymeric material.
FIG. 2a and FIG. 2b show a block diagram illustrating a vibration generator including light emitters in a first and a second operational position according to an embodiment of the invention. The depicted embodiment comprises a driver 110, here an electric motor, and a mass 100 mounted eccentrically on the pivot 105 of the driver 100. The driver 100 drives the eccentrically mounted mass 100 into a rotational movement which causes vibrations. The strength of the generated vibrations can be controlled by the rotational speed of the driver 100 or the electric motor, respectively. Preferably different driving speeds can be adjusted. Further, the speed can preferably be increased gradually. For example speed can increase or decrease with time and this will generate different kind of light effects.
Preferably, the mass 100 can have a semi-cylindrical, hemispheric shape or may present any similar design. The effected vibrations are achieved by an eccentric rotational pivot on which the mass 100 is rotated, advantageously with an adequate fast rotational speed.
Further, the depicted embodiment comprises also two light emitters 200 and 201, here two light emitting diodes (LED). The light emitters 200 and 201 are covered alternately by the reciprocating mass 100. In order to illustrate the alternating coverage FIG. 2a and FIG. 2b depict the operational position of the mass 100 driven by the electric motor 110 scanning between about 180°.
In FIG. 2a the light emitter 201 is covered by the mass 100, that is the light path of the light emitter 201 is intercepted by the mass 100, whereas the light emitter 200 is unobstructed. Direct light can only be obtained from light emitter 200, whereas light of the light emitter 201 may only be obtained by reflection, diffraction and the like of the light on adjacent surfaces.
In FIG. 2b the light emitter 200 is covered by the mass 100, that is the light path of the light emitter 200 is intercepted by the mass 100, whereas the light emitter 201 is uncovered. Direct light can only be obtained from light emitter 201, whereas light of the light emitter 200 may only be obtained by reflection, diffraction and the like of the light on adjacent surfaces.
The alternative covering of the two light emitters 200 and 201 leads to a flashing or stroboscopic effect of the emitted light which advantageously is especially effective in combination with different colors of the light emitted by the light emitters 200 and 201. The two light emitters 200 and 201 emit different colored light.
Additionally, further light effects may be obtained by especially designing the surface of the mass or the shape of the mass. For example, the surface of the mass 100 or an area of the surface can be reflective (e.g. a surface coated by metallic material or a polished surface), and/or colored in order to generate further light effects in combination with the flashing or stroboscopic effect, respectively. The surface of the mass 100 or areas of its surface may be structured, e.g. offering different reflectivity, different color or even light diffraction. The mass 100 may have parts leaving a blank for generating additional effects. Furthermore, the mass can be refractive.
Preferably, the driver 110, the mass 100 and the two LEDs are contained in a common housing 500 or container 500, respectively. Preferably, the inside surface of the housing can have a reflective surface (e.g. a surface coated by metallic material or a polished surface) and/or a colored surface to enhance the generated light effects.
Such a housing 500 can have blanks to transmit the light path or the light of the light emitters 200 and 201. Advantageously, the housing 500 can have a window 310, e.g. a glass window or a window made of translucent polymeric material, to pass through the light of the light emitters 200 and 201. Preferably, the window 310 is translucent, more preferably, the window 310 is transparent. Further, also an opaque window 310 can be used to pass through emitted light. The window can have a rough or profiled surface for scattering incident light. Advantageously, the window can be additionally colored. Further, the window may have optical properties like filter properties, lattice properties or lens properties as known from typical optical means.
The depicted component exciting vibration effects combined with light effects may be built-in a mobile terminal, especially a mobile phone. Such a component implementing light emitters need no additional space or at most little more space. The combination offers several possibilities in application design and in general personalization of such a mobile terminal. The vibrational effects and the light effects can be set up individually by a user e.g. by offering a user interface for defining the effects. For example, the vibration effect can be personalized by switching on/off, by defining the strength of the vibration effect, by defining a periodic excitement of the driver 110 and the like. The light effect can be personalized by defining switching on/off, by defining a color in case of implementing multi-color light emitters, by defining a flashing period of time and the like.
The housing of the mobile terminal containing the component for generating vibration effects in combination with light effects has preferably a window implemented in its housing. The window may be a window having optical properties of the aforementioned window 310.
It will be evident to a person skilled in the art that as the technology advances, the inventive concept can be implemented in a number of ways. The invention and its embodiments are thus not limited to the examples described above but may vary within the scope of the claims.
