发明名称 METHOD AND STRUCTURE FOR PORTABLE PIANO SOUND REFLECTOR
摘要 A portable sound reflector designed to be placed under the soundboard of a piano in order to reflect sound laterally. The preferred embodiment includes a main panel which is held in the proper reflecting orientation by a pair of lateral wings. The lateral wings are preferably hinged to the main panel so that the entire assembly may be folded flat for transportation and storage. A pair of automatically-deploying stays are preferably included. These fold outward and downward to latch the lateral wings in the deployed state when the device is to be used. The hinges are preferably spring-biased toward the open position. This allows the device to assist the user in the unfolding process.
