Abstract
Abstract In a buzzer assembly having an electromagnet having a core and a coil, a driving electronic circuit unit for the latter, a mechanical vibrator unit for being driven periodically by said electromagnet for performing a vibratory movement, and a mechanical resonator unit for receiving vibratory movement from the vibrator unit, all the foregoing units being mounted on a stationary base plate, the improvement resides in that the core and at least a pillar-like supporting member are fixedly mounted at a predetermined and precise mutual relationship for serving as guide means for successive assembly of all the said units excepting the core, and said vibrator and resonator units are fixedly mounted on said pillar-like supporting member or members.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
120 words
A contactless buzzer comprising a base, a plurality of spaced apart pillars secured to said based perpendicular thereto, vibrator arm means having a free end extending in parallel spaced relation to said base and including supporting means mounted on the tops of said pillars, resonator means disposed parallel to said base in contiguous relation to the upper surface of said supporting means and including a resonator disc and a pair of annular supporting rings disposed on opposite sides of said disc adjacent the circumference thereof and electro magnet means mounted on said base and including a coil and a core with said core being disposed perpendicular to said base in alignment with the free end of said vibrator arm means.
Claim 2
Dependent Claim
120 words
A contactless buzzer comprising a base, a plurality of spaced apart pillars secured to said based perpendicular thereto, vibrator arm means having a free end extending in parallel spaced relation to said base and including supporting means mounted on the tops of said pillars, resonator means disposed parallel to said base in contiguous relation to the upper surface of said supporting means and including a resonator disc and a pair of annular supporting rings disposed on opposite sides of said disc adjacent the circumference thereof and electro magnet means mounted on said base and including a coil and a core with said core being disposed perpendicular to said base in alignment with the free end of said vibrator arm means.
Claim 3
Dependent Claim
120 words
A contactless buzzer comprising a base, a plurality of spaced apart pillars secured to said based perpendicular thereto, vibrator arm means having a free end extending in parallel spaced relation to said base and including supporting means mounted on the tops of said pillars, resonator means disposed parallel to said base in contiguous relation to the upper surface of said supporting means and including a resonator disc and a pair of annular supporting rings disposed on opposite sides of said disc adjacent the circumference thereof and electro magnet means mounted on said base and including a coil and a core with said core being disposed perpendicular to said base in alignment with the free end of said vibrator arm means.
Claim 4
Dependent Claim
120 words
A contactless buzzer comprising a base, a plurality of spaced apart pillars secured to said based perpendicular thereto, vibrator arm means having a free end extending in parallel spaced relation to said base and including supporting means mounted on the tops of said pillars, resonator means disposed parallel to said base in contiguous relation to the upper surface of said supporting means and including a resonator disc and a pair of annular supporting rings disposed on opposite sides of said disc adjacent the circumference thereof and electro magnet means mounted on said base and including a coil and a core with said core being disposed perpendicular to said base in alignment with the free end of said vibrator arm means.
Claim 5
Dependent Claim
89 words
A contactless buzzer as set forth in claim 1 wherein said pillars are disposed along the arc of a circle, said supporting means for said vibrator arm means is comprised of an arcuate member having the same radius as said circle, and said annular supporting rings have the same radius as said circle; said supporting means and said annular supporting rings having aligned apertures disposed in alignment with said pillars and means extending through said apertures to secure said vibrator arm means and said resonator means to said pillars.
Claim 6
Dependent Claim
57 words
A contactless buzzer as set forth in claim 2 further comprising a circular circuit board having a plurality of peripheral notches corresponding to and cooperating with said pillars and having an aperture through which said core extends whereby said circuit board is supported by said coil and located relative to said piLlars by means of said notches.
Claim 7
Dependent Claim
24 words
A contactless buzzer as set forth in claim 1 further comprising ring-shaped adhesive members disposed between said annular supporting rings and said resonator disc.
