1245 results about "Flanging" patented technology

Flanging /ˈflændʒɪŋ/ is an audio effect produced by mixing two identical signals together, one signal delayed by a small and gradually changing period, usually smaller than 20 milliseconds. This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series. Varying the time delay causes these to sweep up and down the frequency spectrum. A flanger is an effects unit that creates this effect.

Bent contact member, jack module and electrical connector

The invention relates to the field of electrical connectors, and especially relates to a bent contact member, a jack module and an electrical connector. The front end of the bent contact member is used as a plugging end. The bent contact member comprises a plugging part and a horizontal mounting part disposed behind the plugging part. The front end of the plugging part is provided with a flanging formed through upward bending. The lower side of the bend of the flanging forms a front contact part used for contacting a matching contact member. A concave part which is concave downward relative to the plugging part is arranged between the plugging part and the mounting part. The concave part forms a rear contact part of the contact member. The plugging part gradually slopes downward from back to front from the joint of the plugging part and the concave part. Before use, the front and rear contact parts can be respectively in contact with the root and the end of the matching contact member, so that the formation of a cantilever structure on the matching contact member is avoided or the length of the cantilever of the matching contact member is shortened at least, thereby reducing the insertion loss of a differential connector. In conclusion, the bent contact member can reduce the insertion loss between a plug and a socket of a differential connector.
