Improved speaker frame made of ultra-thin roll material

Abstract

The invention discloses an improved speaker frame made of an ultra-thin roll material. The improved speaker frame comprises a frame body. The frame body is of a bowl shape and is composed of a first-stage step, a second-stage step and a third-stage step from bottom to top, wherein the diameters of the first-stage step, the second-stage step and the third-stage step are gradually increased. A center hole is formed in the center of the bottom of the first-stage step, and a plurality of riveting holes are uniformly formed around the center hole. Two lugs and two single edges are symmetrically arranged on the inclined surface of the second-stage step, shock absorption grooves are formed between the lugs and the single edges, and a plurality of shock absorption holes are formed in the bottoms and the side walls of the shock absorption grooves. The improved speaker frame made of the ultra-thin roll material is made of ultra-thin cold rolling carbon steel sheets and can effectively reduce vibration.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to an improved speaker basin frame made of ultra-thin coil material. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. [0003] The structure of the loudspeaker generally includes a bracket, a magnet, a pot frame, a fixed core support piece, a cone-shaped paper cone, etc. Among them, the pot frame is generally made of steel or aluminum, and its requirements ar...

Problems solved by technology

[0003] The structure of the loudspeaker generally includes a bracket, a magnet, a pot frame, a fixed core support piece, a cone-shaped paper cone, etc. Among them, the pot frame is generally made of steel or aluminum, and its requirements are firm and does not resonate with the sound of the audio equipment. , at this stage, it is impossible to achieve accurate shaping of the basin frame by one-time stamping or casting for ultra-thin cold-rolled carbon steel sheets. The vibration itself has always been a problem that needs to be solved
