Problems solved by technology

This method is more convenient for users, but the disadvantage is that the navigation map development company and the car audio development company need to cooperate to complete the implementation, and the development cycle is long. If the map company does not cooperate, it cannot be realized; and users are also restricted in changing map software.

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0013] Such as figure 1 , the audio processing device includes a main control chip MCU, and the MCU is connected to an audio switch module control end to control the audio switch to realize the playback switching of various input audio signals; the input end of the audio switch receives the audio signals of various audio input modules The audio signal includes the GPS navigation voice signal; the audio switch output terminal is connected with the analog audio output module, that is, the playback device, and the audio signal is output to the playback device for playback.

[0014] The previous implementation method required the cooperation of the map company, and corresponding settings were made in the map software: every time before the GPS sends out the navigation voice, the map software must execute a specially set program segment, and issue an instruction in ad...

Abstract

The invention relates to an audio processing device. The audio processing device comprises a master control chip (MCU), an audio switch module connected to the MCU and controlled by the MCU, other audio input module connected to the input end of the audio switch module, an analog audio output module connected to the output end of the audio switch module, and a GPS navigation voice input module. The GPS navigation voice input module is provided with a digital audio interface, and the interface is connected to the MCU by a navigation voice detection circuit and is connected to an audio switch input end by a navigation voice time-delay circuit. Because of the circuit design, the audio processing device solves the problem that a vehicle-mounted multimedia signal and a GPS navigation voice signal only can be individually played or be freely switched only by a map software program, and is convenient for users. The audio processing device shortens a product development process, saves time and a cost and provides good economic benefits for enterprises.

Description

technical field [0001] The invention relates to an audio processing device, in particular to an audio processing device integrated with a GPS voice navigation function. Background technique [0002] With the rapid development of GPS navigation technology, GPS technology has been widely used in various industries, especially in vehicle electronic products, such as vehicle audio system. The existing car audio system includes rich multimedia functions, such as: DVD / VCD / CD / MP3, Bluetooth, radio, etc., when adding GPS navigation function, it is equivalent to car audio also includes GPS navigation voice system. The prior art has the following implementations in the car audio system to the GPS navigation voice signal: [0003] 1. Single voice playback mode means that only one voice in each media can be played independently in the car audio system. The systems are not connected to each other, and manual control is required to switch between various voices. This method is very trou...
