Signal-sensing device for a cellular phone
First Claim
1. A signal-sensing device for a cellular phone comprising a fixing wrist strap and respective pivoting members for extending around the wrist or hanging in front of the chest whereby the electromagnetic action is utilized to generate attracting and repelling effect in such a way that a vibration generator creates a reciprocating movement for a slight impact such that the skin of the user in contact with the cellphone feels the vibration alert effect, thereby allowing the user to be notified of an incoming call.

Abstract
The present invention relates to a signal-sensing device for a cellular phone having a fixing wrist strap and respective pivoting members. The cellphone is worn on the wrist or the chest so as to eliminate the trouble to take out and return the cellphone and to allow a rapid and easy operation thereof. In addition, the electromagnetic action instead of the complicated and unbalanced vibration produced by the prior art motor type vibrator is utilized to generate attracting and repelling effect. Accordingly, the production cost can be effectively reduced. Meanwhile, an exact vibration signal can be given out as well. Moreover, the noise can be eliminated. Besides, when the cellphone is removed for charging in the charger, a normal ringing sound can be produced due to the electric connection between the cellphone and the charger.

2. A signal-sensing device for a cellular phone further comprising a vibration generator which includes:
-
a) a coil disposed on a coil rack and fixed at the inner side of the contact surface of the cellphone with the wrist;
b) a small hole disposed at the center of the coil and mounted on the coil rack;
c) a shaft-shaped iron rod or a magnet being inserted into the small hole;
d) a metal disc and a spring coil fixed at one side of the iron rod or the magnet which is kept by the spring coil at the center of the small hole of the coil rack, the iron rod or the magnet being located within the small hole for smooth movement;
whereby, when the incoming signal touches the coil, the coil generates magnetic field to attract the iron rod or the magnet and the metal disc such that the front end of the iron rod or magnet penetrates into the small hole and gives impact on the a small hole of the cellphone and when the incoming signal stops, the magnetic field of the coil disappears such that the spring coil brings the iron rod or magnet back to its original position to give impact on the ceiling of the cellphone, and whereby, when the signal comes again, the iron rod or the magnet are attracted by means of the magnetic field to penetrate through the small hole, thereby giving impact on the small hole such that the user feels impact on his wrist and in case of signal stop the impact is created as well such that this so slight vibration can exactly produce vibration alert effect. - View Dependent Claims (3)
