Embodiment Construction

[0017] figure 1 A perspective view of the electrodynamic acoustic transducer according to the first embodiment is shown. The dynamic acoustic transducer has a chassis 130 , a membrane 110 with two grooves 110 a , 110 b , an oscillating coil 120 and a magnet system 140 . The membrane 110 has a hole 150 in the middle. The membrane 110 has an outer membrane carrier 111 and an inner membrane carrier 112 as well as openings or holes 150 . A first groove 110 a is provided between the outer membrane carrier 111 and the coil base 122 , and a second groove 110 b is arranged between the coil base 122 and the inner membrane carrier 112 .

[0018] figure 2 A sectional view of a powered acoustic transducer according to a first embodiment is shown. The dynamic acoustic transducer has a chassis 130 , a membrane 110 with two grooves 110 a , 110 b , an oscillating coil 120 and a magnet system 140 . The membrane 110 here has two grooves, but no cap, ie a hole 150 is provided in the middle...

Abstract

The invention relates to an electrodynamic sound transducer comprising a chassis (130), a membrane (110) with a hole (150) in the center of the membrane (110), a moving coil (120), a magnetic system (140) and a resonator (200) which is placed in the hole (150) in the center of the membrane.

Description

technical field [0001] The invention relates to an electrodynamic acoustic transducer. Background technique [0002] US 8,731,231 B2 shows an electrodynamic acoustic transducer. The powered acoustic transducer has a chassis, a membrane with two grooves, an oscillating coil and a magnet system. The membrane has holes in the middle. [0003] When using headphones, a standing wave occurs between the electroacoustic reproduction transducer that emits sound waves and the head plane. The frequency of the standing wave is related to the distance between the electro-acoustic reproduction transducer and the head plane. The frequency of the standing wave is typically between 5kHz-8kHz in the case of circumaural headphones. Since these frequencies lie in the audible frequency range, distortion of the audio signal occurs here. [0004] In the German patent application claiming priority, the German Patent and Trademark Office searched the following documents: DE 10 2007005 620 A1, W...
