Abstract

Una capsula detectora (100) para detectar la polarización de las ondas que se propagan en las cuerdas (40) de instrumentos musicales de cuerdas, que comprende: para cada cuerda (10) del instrumento musical de cuerdas (40), la capsula detectora (100) está constituido por un disco piezoeléctrico (10) dividido en cuatro cuadrantes (20), que sostiene la respectiva cuerda (40) como puente del instrumento musical de cuerdas (40); al vibrar la cuerda (40) el disco piezoeléctrico (10) se deforma, produciéndose cuatro señales eléctricas provenientes de cada una de los cuadrantes (20), en donde las señales eléctricas provenientes de cada una de los cuadrantes (20) opuestos, son restadas mediante dos amplificadores diferenciales (50) y (60), con lo cual se obtienen dos señales de salida proporcionales al plano de polarización de la cuerda (40); para cada cuerda (40) del instrumento musical de cuerdas (40), la capsula detectora (100), está constituido por un cilindro (90) que sostiene el disco piezoeléctrico (10) dividido en cuatro cuadrante (20), el cual tiene adosado en su superficie una base o muela (30) la cual actúa como puente de la respectiva cuerda (40); las salidas de las señales eléctricas provenientes de cada una de los cuadrantes del piezoeléctrico (10) están conectadas a los amplificadores diferenciales (50) y (60) junto a su punto de tierra común (70).
