Processing technology of headset minitype tone tuning hole and headset

Abstract

The invention relates to the field of electronic equipment, in particular to a processing technology of a headset minitype tone tuning hole. The processing technology comprises the steps that a shell fixture is machined according to the shape of a headset shell; a processing instrument is determined according to the materials of the shell and comprises a laser instrument or an engraving instrument; the selected processing instrument is debugged, and processing parameters for processing the minitype tone tuning hole in the shell are obtained; the shell is fixed to the shell fixture, and the minitype tone tuning hole is processed through the processing instrument according to the processing parameters. The embodiment of the invention further discloses a headset. The processing technology is used for the headset. The minitype tone tuning hole is processed by adopting the laser or engraving technology, the size of the minitype tone adjusting hole can be smaller, and the precision of the minitype tone adjusting hole is better, so that the tone quality effect of the headset is better, the user sensory effect is better, and meanwhile the product percent of pass is higher.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a processing technology of a miniature tuning hole of an earphone and the earphone. Background technique [0002] In the prior art, there has been an earphone technology that does not require a tuning medium, and the required sound quality effect is achieved by controlling the tuning hole aperture. Therefore, the earphone tuning hole plays an important role in debugging the sound quality effect of the earphone. In processing and production, the aperture accuracy of the tuning hole is an important factor affecting the consistency of the objective sound quality curve of the earphone. For the processing of the earphone tuning hole, there are following two methods in the prior art: [0003] First, for the tuning hole whose headphone cavity is a plastic shell, it is directly injected and molded by adding a thimble of the corresponding size in the mold. The diameter of the tuning h...

Problems solved by technology

[0003] First, for the tuning hole whose headphone cavity is a plastic shell, it is directly injected and molded by adding a thimble of the corresponding size in the mold. The diameter of the tuning hole processed by this method is generally φ0.8~1.0mm; for Miniature tuning holes (such as φ0.15mm) are required. If injection molding is still required through a φ0.15mm mold ejector pin, the ejector pin is easily broken during mold assembly and injection molding processing, resulting in low product yield and high processing costs.

[0004] Second, the earphone cavity is the tuning hole of the hardware, which is formed by lathe CNC (Computernumerical control, computer numerical control); similarly, the micro-tuning hole is processed by the lathe CNC, and the corresponding micro-tool is extremely difficult to sink, and The tool is easy to break, wear and tear, and the precision is poor, and CNC machining is basically impossible to achieve effectively

[0005] In summary, the existing technology has shortcomings such as poor precision, difficult processing, low efficiency, and high cost for the processing of micro-tuning holes, and there is no good solution for this
