Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be noted that the following examples are only for illustrating the present invention, but do not limit the scope of the present invention. As such, the following embodiments are only some embodiments, not all embodiments, and all other embodiments obtained by those skilled in the art without making any creative effort belong to the protection scope of the present invention.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a public-switched telephone network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

For a whole machine with a layout of a linear plate (the control main plate is arranged on the long side of the whole machine and is of a linear strip structure), the conventional design scheme is the structure using a plug-in wire connector. The patch cord connector is often arranged above the control mainboard in the dismounting direction due to the thickness problem (namely, the control mainboard is exposed on the upper surface after being arranged on the whole shell), and the reliability of the connector is also poor, so that frequent plugging and unplugging are not facilitated.

The conventional design has two major drawbacks, the first being poor commonality. The left side speaker is not easy to be shared, namely the left side speaker is not easy to be replaced on the right side, and because the distances from the left side speaker and the right side speaker to the control main board are different in the layout of the I-shaped board, the lengths of the patch cords are also different, and the sharing is difficult. The second is poor maintenance. Because the connector is located the control mainboard top, need frequent cartridge connector when the maintenance speaker, in addition, if the maintenance control mainboard, also need take the connector apart, just can tear the control mainboard down the maintenance. The speakers and the control board are interconnected and it is inconvenient to maintain either.

In view of the above problems, and based on the above control main board structure, the present application provides the following solutions.
