Non-contact electronic horn using pure aluminum wire drive coil

Abstract

Provided is a contactless electronic loudspeaker with a pure aluminum wire driving coil. A copper wire is used for wire wrapping of a driving coil of a traditional electronic loudspeaker. The shortcomings that self weight is large, and cost is high exist. The contactless electronic loudspeaker comprises a main control circuit (1) which is connected with a power module (2). The power module comprises the pure aluminum wire driving coil (4) connected with a car power supply (3). The pure aluminum wire driving coil is connected with a switch MOS transistor (5) in series. The main control circuit is connected with the switch MOS transistor (5). The contactless electronic loudspeaker with the pure aluminum wire driving coil is good in use.

Description

Technical field: [0001] The invention relates to a contactless electronic horn using a pure aluminum wire drive coil. Background technique: [0002] The drive coil of the traditional electronic horn uses copper wire, which has the disadvantages of heavy weight and high cost. People once thought of using aluminum coil as an alternative product, but because aluminum wire is not easy to weld and the resistance generates large heat, the resistivity of aluminum wire is greatly affected by temperature, which makes the current through the coil unstable, so it is abandoned. In the existing market, there has never been an aluminum coil as the driving coil of an electronic horn. Summary of the invention: [0003] The purpose of the present invention is to provide a contactless electronic horn using a pure aluminum wire drive coil. [0004] The above objectives are achieved through the following technical solutions: [0005] A non-contact electronic horn using a pure aluminum wire driving coi...
