Problems solved by technology

Although the USB interface can be used to complete data interaction, the USB of most portable terminals currently only supports the Slaver mode. These portable terminals cannot be used as masters to control peripherals through the USB. Therefore, when using the USB interface of a portable terminal, its versatility is limited. Although some existing portable terminals (such as mobile phones) support SD and SIM interfaces, at present most of the terminals have built-in SD interfaces, which cannot be ea

Embodiment 1

[0100] The audio communication system disclosed in this embodiment includes audio equipment and a signal processing device. See figure 1 , the audio equipment includes an audio interface 20, a first audio signal sending module 21, a first audio signal receiving module 22, a digital-to-analog conversion module 23 and a first processing module 24, and the audio interface 20 includes a channel pole, a microphone pole (ie MIC pole) and ground pole; the first processing module 24 is connected with the digital-to-analog mutual conversion module 23, and the digital-to-analog mutual conversion module 23 is connected with the first audio signal sending module 21 and the first audio signal receiving module 22, and the first audio signal sending module 21 is connected to the channel pole of the audio interface 10, and the first audio signal receiving module 22 is connected to the MIC pole of the audio interface. The first processing module 24 is used to send the data to be sent by the a...

Embodiment 2

[0107] In the first embodiment, the audio equipment and the signal processing device realize data interaction through the audio interface of the audio equipment to complete the data communication, but for different audio equipment, usually the position of the microphone (MIC) pole and the ground (GND) pole in the audio interface Not uniform, such as Samsung mobile phones and Apple mobile phones, the positions of the MIC pole and the GND pole in the audio interface are opposite. When the same plug is inserted into the audio interface of the two mobile phones, the middle ring 2 of the plug and the electrical signal connected to the end is not fixed, and its corresponding relationship is shown in Table 1.

Abstract

The invention discloses an audio frequency communication system. A signal processing device is in communication connection with an audio frequency device through an audio frequency interface to achieve the effect that the audio frequency interface of the audio frequency device and the signal processing device conduct data interaction with each other to finish data communication. According to the technical scheme, most of existing portable terminals are respectively provided with an audio frequency interface, the standards of channels of the audio frequency interfaces are basically uniform, therefore, the audio frequency communication system is more convenient to use and better in universality compared with data communication through a USB interface or an SD interface or an SIM interface on the audio frequency device, and can improve the satisfaction of user experience; meanwhile, the signal processing device not only can conduct data interaction with the audio frequency device through the audio frequency interface, but also can transmit data transmitted by the audio frequency device through a corresponding data interface to other communication terminals in communication with the audio frequency device after converting the data, the signal processing device can serve as an interface conversion device between the audio frequency device and the other communication terminals in communication with the audio frequency device, and therefore the communication mode between the audio frequency device and the other communication terminals is further enriched.

Description

technical field [0001] The invention relates to the communication field, in particular to an audio communication system. Background technique [0002] At present, with the development of network technology and telephone technology, Internet banking and telephone banking based on personal computers (PCs) have become quite popular. However, with the continuous changes of various transaction needs, occasions, time, and objects, traditional telephone banking transactions and PC Internet banking transactions can no longer meet the needs of users. With the popularization of portable terminals, especially handheld devices with audio interfaces represented by mobile terminals, it will undoubtedly greatly improve user experience and increase flexibility if transaction payments can be made to portable terminals such as mobile phones and IPADs like PCs. [0003] However, the portable terminal is in the consideration of portability, and the peripheral data interfaces on the portable te...
