Abstract:
(EN) An acoustic waveguide (100) includes a body (101) defining a resonance chamber (102). The body (101) has a tubular section defining a cylindrical central portion (104) of the chamber (102) along a longitudinal axis (108). First and second end sections (110) extend from opposite ends of the tubular section (104). Each end section (110) includes an end wall tapering away from the tubular section and towards the longitudinal axis (108), thus defining a conoidal end portion of the chamber (102).
(FR) L'invention concerne un guide d'ondes acoustiques (100) comprenant un corps (101) délimitant une chambre de résonance (102). Le corps (101) comprend une section tubulaire délimitant une partie centrale cylindrique (104) de la chambre (102) le long d'un axe longitudinal (108). Des première et seconde sections d'extrémité (110) s'étendent à partir d'extrémités opposées de la section tubulaire (104). Chaque section d'extrémité (110) comprend une paroi d'extrémité conique s'éloignant de la section tubulaire et allant vers l'axe longitudinal (108), ce qui délimite ainsi une partie d'extrémité conoïde de la chambre (102).
