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

[0023] Such as figure 1 and figure 2 Shown, a kind of processing technology of the loudspeaker frame with the ear hole of different shapes, comprises the following steps:

[0024] Step 1: cutting, cutting out a piece of square raw material with a side length of 246 mm by a shearing machine;

[0025] Step 2: Punch a positioning hole, and punch out a positioning hole with a diameter of 20 mm in the center of the square raw material through the positioning hole die;

[0026] Step 3: Stretching. The square raw material is stamped into a bowl-shaped semi-finished product through the stretching die with the center of the positioning hole as the center. The inner diameter of the bowl-shaped semi-finished product increases sequentially from bottom to top. The bowl-shaped semi-finished product is composed of three steps from bottom to top. The three steps include a first step 1 with a height of 10.5-11.5 mm, a second step 2 with a height of 1.8-2.2 mm, A third step 3 with a height ...

Abstract

The invention discloses a processing technique for a speaker frame with different shapes of ear holes. The processing technique for the speaker frame with different shapes of ear holes includes steps of cutting, locating hole punching, stretching, punching, trimming, single pattern punching, ear pattern punching, square ear hole punching, flanging, ear hole pressing and round ear hole punching. The processing technique for the speaker frame with different shapes of ear holes punches ear holes in two times.

Description

technical field [0001] The invention relates to the field of manufacturing audio equipment, in particular to a processing technology for speaker basin frames with ear holes of different shapes. 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 ...
