Abstract

Un dispositivo de soporte de micrófonos incluye una llama (2) en forma de anillo, una pluralidad de brazos (4) fijos que se proyectan hacia un lado interior de la llama (2), una pluralidad de brazos (8) móviles que son más largos que los brazos (4) fijos y son desmontables, y múltiples micrófonos (14). Un arreglo de micrófonos de tamaño pequeño se construye acomodando la pluralidad de brazos (8) móviles dentro de la llama (2) en un estado radiante como se muestra en la FIGURA 8 (A). Por otra parte, un arreglo de micrófonos de tamaño grande se construye desplegando radialmente la pluralidad de brazos (8) móviles fuera de la llama (2) como se muestra en la FIGURA 8(B). Al construir un arreglo de micrófonos bidimensional circular, un tamaño del arreglo de micrófonos bidimensional circular se puede cambiar fácilmente de esta manera. Por lo tanto, la localización del sonido puede ser manejada sobre un amplio rango de frecuencias.
