Abstract

An earphone assembly includes a reader module and an audio interface unit. The reader module is in communication with a plurality of radio frequency identification (RFID) tags located at preselected locations. The reader module reads site identification number of the preselected locations from the plurality of RFID tags. The audio interface unit sends the site identification number of the preselected locations to the mobile terminal to control the mobile terminal to play locations introduction information of the preselected locations corresponding to the site identification number.

First claim

What is claimed is:

1 . An earphone assembly comprising:
a reader module in signal communication with a plurality of radio frequency identification (RFID) tags located at preselected locations, the reader module configured to read site identification number of the preselected locations from the plurality of RFID tags; and an audio interface unit configured to send the site identification number of the preselected locations to the mobile terminal to control the mobile terminal to play locations introduction information of the preselected locations corresponding to the site identification number.

2 . The earphone assembly of claim 1 , wherein the audio interface unit is a wire-control audio transmission module and comprises a left channel port, a right channel port, and a microphone port; the earphone assembly obtains power from the mobile terminal through one of the left channel port and the right channel port, receives an audio signal for locations introduction from the mobile terminal through the other one of the left channel port and the right channel port, and sends the site identification number of the preselected locations to the mobile terminal through the microphone port.

3 . The earphone assembly of claim 1 , further comprising an audio processing module, wherein the audio processing module converts an analog audio signal received by the audio interface unit from the mobile terminal into a binary digital signal and sends the binary digital signal to the reader module, the audio processing module further converts a binary digital signal from the reader module into an analog audio signal and sends the analog audio signal to the mobile terminal through the audio interface unit.

4 . The earphone assembly of claim 3 , wherein the audio interface unit is a BLUETOOTH® unit, and the audio processing module is in communication with the mobile terminal through the BLUETOOTH® unit.

5 . The earphone assembly of claim 4 , further comprising a power supply for powering the audio interface unit, the reader module, and the audio processing module.

6 . The earphone assembly of claim 1 , further comprising a storage unit for storing the site identification number of the preselected locations from the plurality of RFID tags and identification number information of the earphone assembly.

7 . The earphone assembly of claim 1 , further comprising an audio playing unit for playing the locations introduction information of the preselected locations from the mobile terminal.

8 . A tour guide system comprising:
a plurality of radio frequency identification (RFID) tags located at preselected locations, each RFID tag pre-storing a site identification number of the preselected locations; a mobile terminal storing and output locations introduction information correlated with the site identification numbers from the RFID tags; and an earphone assembly comprising:
a reader module in communication with the plurality of radio frequency identification (RFID) tags and reading the site identification number of the preselected locations from the plurality of RFID tags; and
an audio interface unit sending the site identification number of the preselected locations to the mobile terminal to direct the mobile terminal to output locations introduction information of the preselected locations corresponding to the site identification number.

9 . The tour guide system of claim 8 , wherein the audio interface unit is a wire-control audio transmission module and comprises a left channel port, a right channel port, and a microphone port; the earphone assembly obtains power from the mobile terminal through one of the left channel port and the right channel port, receives an audio signal for locations introduction from the mobile terminal through the other one of the left channel port and the right channel port, and sends the site identification number of the preselected locations to the mobile terminal through the microphone port.

10 . The tour guide system of claim 8 , further comprising an audio processing module, wherein the audio processing module converts an analog audio signal received by the audio interface unit from the mobile terminal into a binary digital signal and sends the binary digital signal to the reader module, the audio processing module further converts a binary digital signal from the reader module into an analog audio signal and sends the analog audio signal to the mobile terminal through the audio interface unit.

11 . The tour guide system of claim 10 , wherein the audio interface unit is a BLUETOOTH® unit, and the audio processing module is in communication with the mobile terminal through the BLUETOOTH® unit.

12 . The tour guide system of claim 11 , further comprising a power supply for powering the audio interface unit, the reader module, and the audio processing module.

13 . The tour guide system of claim 8 , further comprising a storage unit for storing the site identification number of the preselected locations from the plurality of RFID tags and identification number information of the earphone assembly.

14 . The tour guide system of claim 8 , further comprising an audio playing unit for playing or displaying the locations introduction information of the preselected locations from the mobile terminal.

15 . The tour guide system of claim 8 , further comprising a server, wherein the server stores site identification number of the preselected locations and locations introduction information, the mobile terminal downloads and stores the site identification number of the preselected locations and the locations introduction information from the sever.

16 . The tour guide system of claim 15 , further comprising a plurality of RFID readers, wherein the RFID readers are dispersedly located at the preselected locations and are in communication with the server, the RFID reader obtains the identification number information of each earphone assembly which is in the radiation radius of the RFID reader and outputs the identification number information of the earphone assembly to the server; the server records a total amount of the tourists at the preselected locations according to the received identification number information of the earphone assembly and feedbacks the total amount of the tourists to the mobile terminal.

17 . The tour guide system of claim 15 , further comprising a plurality of two-dimension code tags located at the preselected locations, wherein each two-dimension code tag stores two-dimension code information indicating a location of the two-dimension code tag; the mobile terminal obtains the two-dimension code information and sends the two-dimension code information to the server, and the server records a total amount of the tourists at the preselected locations and sends a feedback signal indicating the total amount of the tourists at the preselected locations to the mobile terminal.

18 . The tour guide system of claim 15 , further comprising a plurality of inquiring terminals, wherein the inquiring terminals are positioned at preselected locations and are electrically connected to the server, the inquiring terminals are configured to inquire locations introduction information according to the site identification number information input by the tourists.
