Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The earphone in the prior art has three standards, wherein one standard is a common three-section type, namely a left sound channel pin, a right sound channel pin and a grounding pin; one is four-section type of OMPT standard, namely left channel pin, right channel pin, microphone pin and grounding pin; one is four-segment type of CTIA standard, namely left channel pin, right channel pin, ground pin and microphone pin. However, the existing terminals such as televisions and set-top boxes can only be compatible with one of three-section earphones and four-section earphones of common standards, and cannot be compatible with earphones of three standards at the same time.

Based on this, the present invention is intended to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.

As shown in fig. 1 and 2, the present invention provides an earphone adapter fitting including a plug portion 10, a socket portion 20, and a cable 30 disposed between the plug portion 10 and the socket portion 20 for connection. The plug portion 10 is used for inserting a terminal device, and the plug portion is defined as a first pin 11, a second pin 12 and a third pin 13 from inside to outside in sequence; the socket part 20 is used for plugging an earphone, and is defined as a first section 21, a second section 22, a third section 23 and a fourth section 24 from inside to outside in sequence; the third section 23 is short-circuited with the fourth section 24; the cable 30 includes a first signal line for connecting the first pin 11 and the first segment 21, a second signal line for connecting the second pin 12 and the second segment 22, and a third signal line for connecting the third pin 13 and the third segment 23 or the fourth segment 24; the first signal line, the second signal line and the third signal line are insulated from each other. The terminal can be a television, a set-top box or a sound box.

Further, the cable 30 further includes an insulating layer, the insulating layer wraps the outer surfaces of the three signal lines, it is easy to understand that at this time, the three signal lines may be twisted together to form a wire core, the outer surface of the wire core wraps a plastic insulating layer, and certainly, the outer surface of each signal line wraps a plastic insulating layer independently.
