Method used

[0017] During use, a wireless transmitter is set at the entrance or appropriate location of each scenic spot in the scenic spot, and the wireless transmitter emits a wireless signal with coded information corresponding to the scenic spot. When there is no wireless signal, the user can use the second voice processing unit 15 to play various background sounds stored in the storage unit 13, such as music. When the wireless receiving unit 12 receives the wireless signal transmitted by the wireless transmitter, the wireless signal is identified through the central processing unit 11, and the commentary corresponding to the coded information is read from the storage unit 13, and the first voice processing unit is started 14 decodes the digitally coded commentary, A/D converts it, and outputs it through the voice output unit (earphone or loudspeaker) 16 . The central processing unit 11 can choose to close or reduce the output volume of the second speech ...

Abstract

The present invention relates to a wireless guide, which comprises a central processing unit, a wireless receiving/sending unit to receive external wireless trigger signals, a memory unit to memorize commendatory and background sound data, at least two voice processing units to respectively process the commendatory and the background sound data and a voice output unit connected with the voice processing unit. Based on the structure above, it is necessary to select and control the voice processing unit to respectively or jointly play the commendatory and background sound according to actual situations, thus enabling users to listen to various sounds during listening to the commendatory or at free time relying on the wireless guide and increasing practicality of the wireless guide.

Example Embodiment

[0015] The present invention will be described in detail below with reference to the drawings and embodiments.
[0016] As shown in Figure 1, the wireless guide device 1 of the present invention includes: a central processing unit 11; a wireless receiving unit 12 for receiving external wireless trigger signals; a storage unit 13 for storing commentary and background sound; The first voice processing unit 14 and the second voice processing unit 15 that process the background sound; and the voice output unit 16 connected to the first voice processing unit 14 and the second voice processing unit 15.
[0017] When in use, a wireless transmitter is set at the entrance or appropriate location of each scenic spot in the scenic spot, and the wireless transmitter transmits a wireless signal with coded information corresponding to the scenic spot. When there is no wireless signal, the user can use the second voice processing unit 15 to play various background sounds stored in the storage unit 13, such as music. When the wireless receiving unit 12 receives the wireless signal transmitted by the wireless transmitter, the wireless signal is recognized by the central processing unit 11, and the commentary corresponding to the encoded information is read from the storage unit 13, and the first voice processing unit is activated 14 Decode the digitally encoded commentary, A/D conversion and output through the voice output unit (headphone or speaker) 16. The central processing unit 11 may choose to turn off or reduce the output volume of the second voice processing unit 15 in response to the wireless signal, so as to prevent background sounds from interfering with the user listening to the commentary. In addition, wireless transmitters can be set at the exits of various scenic spots or other suitable locations. When the user leaves the scenic spots, the wireless receiving unit 12 will also receive wireless signals, and the central processing unit 11 will turn off the first voice processing unit 14 in response to the wireless signals. , Stop the commentary, and at the same time start or increase the output volume of the second voice processing unit 15 that plays the background sound, the user can continue to listen to the background music. In this embodiment, the first and second speech processing units 14 and 15 preferably adopt MP3 players to improve the sound playback quality. The storage unit 13 preferably adopts a flash memory or a micro hard disk to facilitate the updating of stored data.
[0018] The wireless guide device 1 further includes a display unit 17 connected to the central processing unit 11. The storage unit 13 stores a scenic spot map, and the scenic spot map is displayed by the display unit 17. The central processing unit 11 responds to wireless trigger signals at the entrance and exit to display identification marks at appropriate locations on the scenic spot map displayed by the display unit 17, so that the user can understand the current location. At the same time, the central processing unit 11 displays information corresponding to the scenic spot on the display unit 16 in response to the wireless trigger signal, so as to facilitate the user to further understand the scenic spot.
[0019] In the foregoing embodiments, the present invention is only exemplarily described, but those skilled in the art can design various implementations according to different actual needs without departing from the scope and spirit of the protection of the present invention.
