Title:
ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
Japanese Patent JP3194664
Kind Code:
B2
Abstract:
PURPOSE: To simplify the structure and also to improve the reproducibility of acoustic characteristic for an electroacoustic transducer having a partition wall and a mask by forming the mask with the flange of a magnet system.
CONSTITUTION: This transducer 1 includes a diaphragm 5, a partition wall 24 that is located at the back of the diaphragm 5 and has openings 25 to 28 and 29 to 32, a mask 37 having its openings 38 to 40, etc. The coincidence is secured between the openings 38 to 40 and the different partition wall openings via various relative positions set between the wall 24 and the mask 37. When the mask 37 is formed with the flange of a magnet system 16 of the transducer 1, the structure of the mask 37 is simplified. Furthermore, the influence of additional allowance due to the mask 37 is never caused and the reproducibility of acoustic characteristic is improved.
