Electric heater to maintain operating temperature of stringed music instruments - has heat transferred from electric bulbs to application sites and uses fibre=optic guides to illuminate controls

摘要

The heat source is mounted in an insulated box fitted into the instrument and heated by electric connections to the outside. The light sources are electric lamps mounted on a heat sink. The heat is conducted to different sites on the instrument by metal cables, while fibre optics transfer light to the instrument controls. The heat output can be regulated electrically and/or by sliders (2) covering the box. Halogen lamps can be used for larger instruments e.g. pianos. The electric supply can be taken from the integral amplifier e.g. electric guitars. ADVANTAGE - Ensures instruments stay in tune e.g. for outside performances.
