Problems solved by technology

[0003] The structure of the loudspeaker generally includes a bracket, a magnet, a basin frame, a fixed core support piece, a cone-shaped paper cone, etc. Among them, the basin 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, the processing technology of the pot frame is mainly obtained by forming and stamping a single piece of raw material at one time. This processing technology has the problems of low dimensional control accuracy and high defective rate, especially in the pot frame. For more delicate components such as ear flowers and ear holes, traditional craftsmanship cannot be achieved

Embodiment 1

[0019] Such as Figure 1 to Figure 2 Shown, a kind of processing technology of the loudspeaker basin frame of binaural hole, comprises the following steps:

[0020] Step 1: blanking, punching positioning holes; cutting out a piece of circular material with a diameter of 250 mm by blanking die, said circular material is a steel plate of 0.8 mm, and punching at the center of said circular material by positioning hole die Make a positioning hole with a diameter of 20 mm, and perform preliminary shaping to remove the round material and burrs with a height greater than 0.2 mm around the positioning hole. Wherein, the blanking die is a 40T punch press, and the positioning hole die is installed on a 16T punch press.

[0021] Step 2: stretching and pressing the reinforcing rib; stretching the round material obtained in step 1 through the stretching die, and punching the reinforcing rib 1 to obtain the pot frame blank; the depth of the pot frame blank is 59 mm, and the The diameter o...

Abstract

The invention discloses a processing technology of a speaker frame with double ear holes. The processing technology of the speaker frame with the double ear holes includes a series of steps of rough shape cutting, location hole punching and extension, reinforcing rib pressing and shape punching, riveting hole punching, mounting hole punching, center hole punching and ear flower punching, and ear hole punching, simple flower punching and reverse edge punching. The processing technology of the speaker frame with the double ear holes can perform continuous processing and repeated punching, and is high in precision.

Description

technical field [0001] The invention relates to the field of loudspeaker manufacturing, in particular to a processing technology of a binaural loudspeaker basin frame. 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 requirem...
