Vibrator alert device for a communication receiver
First Claim
1. An alert device for vibrating a portable communication receiver being enclosed in a housing, the communication receiver having a decoding means for generating an alert signal in response to detecting received information, said alerting device comprising:
- a rotational motive means for rotating a shaft about a first axis of rotation, the motive means being responsive to the alerting signal for converting electrical energy to mechanical energy to drive the shaft;
an eccentric weight capable of being rotated about a second axis of rotation to generate tactile vibration in the housing;
support means coupled to the housing for fixing said eccentric weight onto the housing during rotation of said eccentric weight and transmitting vibrating motion generated by the eccentric weight to the housing; and
linking means coupling the shaft to said eccentric weight for transmitting rotational movement from the shaft to the eccentric weight while preventing translational movement from being transmitted between the eccentric weight and shaft, the linking means further providing for the transmission of rotational movement when the first axis of rotation is offset from the second axis of rotation.

Abstract
An alerting device for a paging receiver for generating vibration motion in the paging receiver housing. The alerting means comprises an electric motor, an eccentric weight, and a linking means. The electric motor is activated in response to an alert signal for rotating a driving shaft. The driving shaft is coupled to the eccentric weight by the linking means for rotating the eccentric weight. The linking means includes a driving means and a receiving means such that rotary motion is transmitted from the shaft to the eccentric weight while preventing transmission of vibration motion from the eccentric weight to the shaft. The eccentric weight is mechanically attached to the housing for transmitting the vibration motion directly to the housing without passing the vibration motion through the electric motor.
