Hypochondriasis (2014)

Hypochondriasis is for chin (guqin) and live electronics. Chin is an ancient Chinese 7-string zither normally played by plucking with fingers. This piece is my first work to use electronics. For the first experiment on electronics, I choose the chin as the instrument since it’s one of the instruments I’m familiar with. However, the chin is a very personal instrument due to its soft volume and subtle timbral changes, so amplification becomes an important element and thus creates a new kind of environment, an augmented chin.

…sicut aurora procedit (2015)

…sicut aurora procedit is the composition created by Maija Hynninen for a multidisciplinary work Pix grace – Rosin. The work was conceived by violinist Mirka Malmi, composer Maija Hynninen and aerialist Ilona Jäntti during 2013–15. Interaction between the group members was tight, each producing demo material for the rest of the group to see and discuss. The name Rosin came from the idea of rosin combining the two, violinist and aerialist. By friction rosin creates a contact surface between the bow and strings, the hands of the aerialist and the trapeze.

Multi-Channel Paper Speaker

This is a 4-channel paper speaker. Note that the geometry of the electromagnetic field production, and the 4-channel system has been intentionally obscured by artistic concerns. With these 2-d speaker arrays, artistic and design possibilities open up for sound art, sound installation, patterning and graphic design, which are not part of standard sound reproduction aesthetics.

Screen Printed Speaker

Here's two different conductive inks. The black bare conductive ink has better printing properties - it can pass easily through a 130 mesh screen and won't dry up. However, it's resistivity is higher than the copper paint on the left. The copper paint, from less EMF, is problematic for basic screen printing.

Large Multi-Hexagram Speaker

The same parallel/serial structure used to produce the smaller hexagram speaker at the top of this page can also be multiplied to make larger speakers. The more hexagram parallel structures (with magnets attached), the greater the potential volume output. This sheet (12" x 17" approx) is enough to drive a very robust signal.

computer keyboard Audio Speaker

One way to quickly and easily make an flat audio speaker is to re-appropriate already printed electronics. This is a speaker which uses the innards of a computer keyboard. A small grid-like layer of silver ink has been applied to a thin plastic surface, which is used to read keystrokes.

Topologies for Paper Speakers

This figure shows the three basic topologies of circuit design for paper speakers which I have explored. All three designs can generate a magnetic field capable of driving audio.
