Problems solved by technology

[0003] The miniature sounder of the related art includes a pot frame and a magnetic frame fixed on the pot frame. The fixing method of the magnetic frame of the sounder and the pot frame is to inject the magnetic frame into the pot frame. When this method fixes the magnetic frame, the magnetic The outside of the frame needs to be wrapped with plastic, and then injected, which is not conducive to the improvement of production efficiency; or the magnetic frame and the basin frame are fixed with glue, and this glue bonding method requires a glue tank on the basin frame , thus occupying the use space of the pot frame and limiting the customer's demand for related products

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as Figure 1-2 As shown, a method for fixing a magnetic frame and a basin frame, the method includes the following steps:

[0018] A pot frame 2 is provided, and a plurality of positioning columns 4 are arranged on the pot frame 2;

[0019] A magnetic frame 3 is provided, and the magnetic frame 3 is provided with a plurality of positioning holes 5 which are connected with the positioning column 4;

[0020] Assemble the magnetic frame 3 to the basin frame 2, make the positioning hole 5 and the positioning column 4 fit and connect, then heat the positioning column 4 to partially melt and deform it, and press the melted and deformed part of the positioning column 4 against the positioning hole of the magnetic frame 3 5 and make the outer diameter of the melted and deformed part of the positioning post 4 larger than the diameter of the positio...

Abstract

The invention provides a fixing method of a magnet frame and a basin bracket, which comprises the following steps of providing the basin bracket, wherein a plurality of positioning columns are arranged on the basin bracket; providing the magnet frame, wherein a plurality of positioning holes coordinately connected with the positioning columns are arranged on the magnet frame; assembling the magnet frame on the basin bracket so that the positioning holes and the positioning columns are coordinately connected; heating the positioning columns so that a part of each positioning column is melted and deformed; pressing the melting parts of the positioning columns to the positioning holes of the magnet frame so that the external diameter of the melting part of each positioning column is larger than the diameter of each positioning hole; and cooling the positioning columns so that the magnet frame is fixed to the basin bracket. The method for fixing the magnet frame and the basin bracket has the advantages that the external side of the magnet frame does not require plastic hems when the magnet frame is fixed to the basin bracket, which facilitates to enhance the productivity; a glue slot is not required to be arranged on the basin bracket so as to save the use space of the basin bracket and meet the miniaturization requirements of clients on the relative products.

Description

【Technical field】 [0001] The invention relates to a method for fixing a magnetic frame and a basin frame, in particular to a method for fixing a magnetic frame and a basin frame of a miniature sounder. 【Background technique】 [0002] Miniature sound generators are widely used in portable electronic devices such as mobile phones, notebook computers, and hearing aids. With the rapid development of these portable electronic devices, people's functional requirements are getting stronger and stronger, and the miniature sound-generating devices applied to them are also developing correspondingly and rapidly. [0003] The miniature sounder of the related art includes a pot frame and a magnetic frame fixed on the pot frame. The fixing method of the magnetic frame of the sounder and the pot frame is to inject the magnetic frame into the pot frame. When this method fixes the magnetic frame, the magnetic The outside of the frame needs to be wrapped with plastic, and then injected, whi...
