Hand-held sound digitizer system

Claim 2

A hand-held sound digitizer system for recording sound in a personal computer, comprising: an enclosure capable of being held in one hand; a microphone built into said enclosure for providing an analog sound signal output; means within said enclosure for digitizing said analog signal output; means for providing the digitized output to a parallel printer port of the computer and controller means resident within the computer enabling said means for digitizing to allow transfer of said digitized output to said parallel printer port by way of said means for providing to store said digitized output in the computer.

Claim 3

The sound digitizer system of claim 1 in which said means for digitizing includes an A/D converter.

Claim 4

The sound digitizer system of claim 2 in which said A/D converter provides serial data output.

Claim 5

The sound digitizer system of claim 3 in which said means for providing includes means for reading the serial data output into the computer.

Claim 6

The sound digitizer system of claim 4 in which said means for reading includes means for assembling a plurality of data bits.

Claim 7

The sound digitizer system of claim 5 in which said means for reading includes means for transferring said assembled data bits as a group to the parallel printer port.

Claim 8

The sound digitizer system of claim 5 in which said means for assembling includes a shift register.

Claim 9

The sound digitizer system of claim 5 in which said plurality of bits is four bits.

Claim 10

The sound digitizer system of claim 4 in which said means for reading includes means for serially transferring data bits to the parallel printer port.

Claim 11

The sound digitizer system of claim 4 in which said means for digitizing includes pulse generator means for providing a pulse to said A/D converter for generating a data bit from the microphone output.

Claim 12

The sound digitizer system of claim 10 in which the pulse leading edge enables said A/D converter.

Claim 13

The sound digitizer system of claim 5 in which said means for digitizing includes pulse generator means for providing a pulse to said means for assembling for generating a data bit from the microphone output.

Claim 14

The sound digitizer system of claim 12 in which the pulse trailing edge enables said means for assembling.

Claim 15

The sound digitizer system of claim 1 further including means within said enclosure for amplifying the microphone output before digitization.

Claim 16

The sound digitizer system of claim 1 further including input means within said enclosure for accepting an analog sound signal and providing an analog sound signal output, distinct from said microphone analog sound signal output, for said means for digitizing.

Claim 17

A hand-held sound digitizer system for recording sound in a personal computer, comprising: an enclosure capable of being held in one hand; a microphone built into said enclosure for providing analog sound signal output; means for amplifying said microphone output; a serial A/D converter for digitizing said amplified analog sound signal output; controller means resident within the computer for enabling said serial A/D converter to provide a digitized output; and means for reading the digitized output through a parallel printer port of the computer into the computer memory.

Claim 18

A hand-held sound digitizer system for recording sound in a personal computer, comprising: an enclosure capable of being held in one hand; a microphone built into said enclosure for providing analog sound signal output; means for amplifying said microphone output; a serial A/D converter for digitizing said amplified analog sound signal output; controller means resident within the computer for enabling said serial A/D converter to provide a digitized output; and means for reading the digitized output through a parallel printer port of the computer into the computer memory.

Claim 19

A hand-held sound digitizer system for recording sound in a personal computer; comprising: an enclosure capable of being held in one hand; a microphone built into said enclosure for providing an analog sound signal output; means for amplifying said microphone output; a serial A/D converter for digitizing said amplifier analog sound signal output; means for assembling a plurality of sound signal bits into a group of bits; and controller means resident within the computer for generating a pulse for enabling both said serial A/D converter and said means for assembling to both digitize said analog signal and transfer into the computer said group of bits through a parallel printer port of said computer.

Claim 20

A hand-held sound digitizer system for recording sound in a personal computer; comprising: an enclosure capable of being held in one hand; a microphone built into said enclosure for providing an analog sound signal output; means for amplifying said microphone output; a serial A/D converter for digitizing said amplifier analog sound signal output; means for assembling a plurality of sound signal bits into a group of bits; and controller means resident within the computer for generating a pulse for enabling both said serial A/D converter and said means for assembling to both digitize said analog signal and transfer into the computer said group of bits through a parallel printer port of said computer.
