Problems solved by technology

[0006] The problem brought about by the above situation is that when the speaker is replaced, the acoustic parameters will change accordingly. Therefore, it is necessary to modify or even redesign the mechanical structure of the phone.
However, this complex installation method is not suitable for conventional loudspeaker
That is to say, this installation method is not suitable for existing handsets

Abstract

The invention relates to the field of communication, particularly a method for producing and detecting an earphone. The earphone, which is made by using the method for producing and detecting an earphone applicable to multiple types of wide-band loudspeakers, can adapt to multiple types of loudspeakers. The method comprises the following steps: arranging a plurality of die layouts for making multiple types of earphones according to acoustic characteristics of the multiple types of loudspeakers; respectively detecting the die layouts; determining the die layouts, so that the die layouts are respectively corresponding to the multiple types of earphones; extracting a loudspeaker, and determining the specific type of the extracted loudspeaker; selecting the die layout corresponding to the specific type according to the specific type of the extracted loudspeaker; producing the specific type of earphone by using the selected die layout; and assembling the extracted loudspeaker into the specific type of earphone.

Description

【Technical field】 [0001] The invention relates to the communication field, in particular to a production detection method of a receiver, which can realize the self-adaptation of the receiver taking into account multiple types of loudspeakers. 【Background technique】 [0002] Telecommunications networks have been able to provide audio communications over a wider frequency band than the standard 300-3400 Hz band. [0003] By adopting an appropriate multimedia digital signal codec, it is possible to transmit and receive wideband audio signals and full-band signals, thereby greatly improving communication quality. [0004] Even though some handsets integrate this technology to enable wideband communication, only a small percentage of phones are able to acoustically reproduce wideband electrical signals and the overall richness of the full-band signal. [0005] The following situation is often encountered in the production process of the existing handheld receivers: once the loud...
