Title: Electroacoustic transducer
Inventor: UENO YOSHIAKI
IPC: H04R3/00
Filed: 1990-07-14
Abstract: PURPOSE:To obtain a strong directivity regardless of miniaturization by bending an inner space of a cylinder from a sound source to an opening and forming a reflecting face to a bent part. CONSTITUTION:A secondary sound wave is generated in each cylinder 2 from a primary sound wave sent from each sound source 1 and the primary sound wave is eliminated by an acoustic filter 4 and only the secondary sound wave is sent. Moreover, since a reflecting face 5 is formed in the cylinder 2, a side lobe due to a reflection wave is liable to be generated in the vicinity of an end of the reflecting face 5, but since a sound absorbing member 6 is arranged to an inner circumferential face of the cylinder 2 between the reflecting face 5 and the opening 3, the side lobe is eliminated and the directivity of the secondary sound wave is intensified. Furthermore, since the two opening sections 3 are arranged side by side, a desired directivity is realized.
