一个游戏，声音也是非常的重要，其实cocos2dx里面的简单音效引擎的使用是非常简单的。我这里只不过是用一个类对所有的音效进行管理罢了。

Audio.h

#ifndef _AUdio_H_
#define _AUdio_H_
class Audio{
public:
	static Audio* getInstance();
	void playBGM();
	void playReadyGo();
	void playPop();
	void prepare();
	void playCombo(int size);
private:
	static Audio* m_instance;
};
#endif

#include "Audio.h"
#include "SimpleAudioEngine.h"
Audio* Audio::m_instance = nullptr;
Audio* Audio::getInstance(){
	if(m_instance == nullptr){
		m_instance = new Audio();
	}
	return m_instance;
}

void Audio::playBGM(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic("Music/music.ogg",true);
}

void Audio::playReadyGo(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/readygo.ogg",false);
}

void Audio::playPop(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/pop.ogg",false);
}

void Audio::playCombo(int size){
	if(size < 5)
		return;
	if(size >= 10){
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_3.ogg",false);
	}else if(size >= 7){
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_2.ogg",false);
	}else {
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_1.ogg",false);
	}
}
void Audio::prepare(){
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadBackgroundMusic("Music/music.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/readygo.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/pop.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_1.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_2.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_3.ogg");
}
