Electrodynamic speaker

Back in the early part of the 20th century, people were still exploring the basic knowledge of math and frequencies. While the electromagnet part of the speaker originates from the s, it took 40 more years to develop a knowledge of acoustics and materials. Rice and E. Kellogg finally invented it by solving the final part of the puzzle.

Ads are not permitted. When I got it, the speaker cone was in bad shape. I attempted to repair it, but I think it would sound better if I just replaced it. I have not had any success finding an electrodynamic replacement speaker for it. Is it necessary to replace it with an electrodynamic speaker, or would a permanent magnet speaker work? If the radio hasn't had the capacitors replaced your audio problem might be electrical. You can buy electro dynamic speakers at a number of places this place is great. When I re-coned it I didn't get a good seal around the voice coil and now it has a horrible buzzing sound and and cuts out most of the low frequencies. I looked into having it professionally re-coned, but that would cost more than the radio is worth.

The coil, which is positioned in the air gap of the magnet, a diaphragm that is rigidly attached to the coil, and the magnetic system constitute the speaker unit see Figure 1. The interaction of the current and the magnetic field produces mechanical vibrations of the diaphragm that are accompanied by the radiation of sound waves either directly, as in a direct-radiator loudspeaker, or through a horn, as in a horn loudspeaker. To ensure operational reliability and high-quality sound, the speaker unit is housed in a wooden, plastic, or metal cabinet. Figure 1.

May 1; F. This invention relates to an electrical apparatus and particularly to a permanent magnet type of loud speaker. The invention has particular application to dynamic speakers employing permanent magnets of such materials as Alnico 5 or 6 or similar anisotropic material having a preferred axis of a magnetization. Permanent magnet types of dynamic speakers have generally provided a length of permanent magnet cooperating with a pot of the open or closed type.

Due to its versatile mechanical and electrical properties, silicon has taken over the microelectronic and micromechanical worlds. This combination has created product categories such as smartphones and wearables, which would have belonged to science-fiction thirty years ago. Originally patented in , the electrodynamic speaker is a holdover from the 19th century still surviving in our 21st-century products. As one of the only two smartphone functions not having transitioned to solid-state technology, it is responsible for the lacklustre audio performance ubiquitously decried by users. USound has developed its MEMS products such as Ganymede to address that issue and bring a superior audio experience to the mobile world.

A speaker driver is an individual loudspeaker transducer that converts an electrical audio signal to sound waves. While the term is sometimes used interchangeably with the term loudspeaker speaker , it is usually applied to specialized transducers which reproduce only a portion of the audible frequency range.
