An improved loudspeaker basin made of ultra-thin cold-rolled carbon steel sheet

Abstract

The invention discloses an improved loudspeaker pot frame made of ultra-thin coil material, which includes a pot frame body, the pot frame body is bowl-shaped, and the diameter of the bowl-shaped pot frame body increases gradually from bottom to top The first level of steps, the second level of steps and the third level of steps are formed, the center of the bottom of the first level of steps is provided with a middle hole, and a number of riveting holes are uniformly arranged around the middle hole, so that The inclined surface of the second level of steps is symmetrically provided with two ear flowers and two single flowers, and a shock absorbing groove is arranged between the ear flowers and the single flowers, and the bottom and side walls of the shock absorbing groove There are several damping holes. The invention aims to provide a loudspeaker basin frame made of ultra-thin coil material, which is made of ultra-thin cold-rolled carbon steel sheet and is beneficial to reduce vibration.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to an improved loudspeaker frame made of ultra-thin cold-rolled carbon steel sheets. 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...

AI Technical Summary

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 pot frame by one-time stamping or casting for ultra-thin and ultra-thin cold-rolled carbon steel sheets. At the same time, how to overcome the impact of the paper cone and speaker box vibration on the pot frame, reduce The vibration of the pot frame itself has always been a problem that needs to be solved
