移动音频IC应用领域主要是手机和MP3 播放器，现在扩展到游戏机、手持导航、数码相机等领域。不过相对于手机和MP3播放器，这些应用所占的比例还是不大。手机用音频IC主要有3类，一是和弦IC，二是CODEC，三是音频放大IC。MP3播放器用音频IC主要是MP3解码IC和CODEC。
和弦IC市场前景暗淡，全球主要的手机厂家诺基亚、摩托罗拉、索尼爱立信、西门子都极少采用和弦IC 。尤其是2005年以后，这四大厂家一般采用应用处理器和定制模拟基频来完成和弦功能。早期采用和弦芯片的厂家主要是日本手机厂家、三星、LG和国产厂家。而现在只有日本厂家还坚持使用和弦IC，其余厂家全部放弃了和弦IC。
音频CODEC领域的厂家不多，主要有TI、AKM和欧胜微电子。音频CODEC的进入门槛颇高，精通DELTA-SIGMA变换的厂家才能在此领域具备一席之地。并且音频CODEC最多应用在压缩音乐播放器上，特别是MP3和数码相机上，用量巨大。对音频CODEC厂家来说，手机只是副业，即便失去也不会太在意。MP3播放器领域， WOLFSON一支独秀，几乎垄断了市场。而在非便携音乐播放器，如CD机和专业音响设备领域，ADI、AKM、Cirrus占据着主要市场，WOLFSON甚少插足高音质市场。这些厂家相对保守，对便携音乐播放器领域不太重视。不过Cirrus近来主动出击，据称打败WOLFSON进入苹果的下一代IPOD中。
随着高音质音乐手机的大量出现，手机用CODEC的比例越来越高，诺基亚因为一向和德州仪器合作，因此其音频CODEC都是德州仪器提供。AKM是日本化工巨子旭化成旗下一个很小的分公司，作风保守，很少主动出击，市场局限在日本和韩国。厂家通常只能选择WOLFSON。
音频放大IC单独出现的手机越来越多，此前音频放大都集成到模拟基频里。诺基亚2008年大约85%的手机都采用独立的音频放大IC，三星则大约70%的手机采用独立的音频放大IC。摩托罗拉和索尼爱立信则较少使用独立的音频放大IC。目前手机中的音频放大有朝两个发展的趋势，一是耳机驱动放大器，再一个是扬声器驱动放大器。诺基亚手机常见此类配置。
手机领域，D类放大的占有率超过了50%，D类音频放大器常见的有TPA2010D1、TPA2012D2、TPA2005D1、YDA144、YDA1454、TPA4411、TPA6310A2、SAPA1D2。新手机尤其是诺基亚大量采用D类音频放大，并且是双放大，一个是驱动耳机，一个驱动扬声器。
Mobile audio IC is mainly applied to mobile phone and MP3 players and now it is extended to game console, hand-held navigation, digital camera and other fields. However, application in these fields is still small, compared to that in mobile phone and MP3 players. Mobile phone audio IC is divided into three categories, namely melody IC, CODEC, and audio amplifier IC. The audio IC of MP3 players mainly adopts MP3 decoder IC and CODEC.
Melody IC market prospects are bleak. Key global mobile phone manufacturers, like Nokia, Motorola, Sony-Ericsson and Siemens, seldom adopt melody IC. Especially since 2005, the four big producers have generally used application processor and customized analog baseband to replace melody IC. In early stage, mainly Japanese mobile phone producers, Samsung, LG and Chinese handset producers adopted melody IC chips. Nowadays, only Japanese manufacturers still insist on adopting melody IC, and the rest all have given it up.
There are only a small number of audio CODEC manufacturers, mainly TI, AKM and Wolfson Microelectronics. Audio CODEC market entry threshold is very high, and only the manufacturers mastering DELTA-SIGMA conversion can win themselves a place in the field. What’s more, audio CODEC is mostly applied to compressed music players, and especially a huge amount is used in MP3 and digital camera. To CODEC producers, mobile phone is only their sideline business, about which they don’t care much, if they lose it. As for MP3 player, Wolfson is absolutely the market dominator, monopolizing the market. As for non-portable music players like CD player and professional acoustics equipment, ADI, AKM and Cirrus share the market. Wolfson is seldom involved in the high-quality audio market. These manufacturers are comparatively conservative, and they don’t pay much attention to portable music players. However, Cirrus has aggressively entered the field recently, claiming that it has beat Wolfson and would have its audio CODEC applied in the next generation of Apple iPods.
With a large amount of high-quality audio mobile phones put into the market, more and more mobile phones have started adopting CODEC. Nokia has cooperated with TI all the time, so all of its audio CODEC is provided by TI. AKM, a small subsidiary of Asahi Kasei Corp., a Japanese chemical giant, has behaved conservatively, so its market is only restricted in Japan and South Korea. Normally, Wolfson is the only choice to producers.
Nowadays, independent audio amplifier IC is more and more used in mobile phones, while it used to be entirely integrated into analog baseband in the past.
About 85% of Nokia’s mobile phones use independent audio amplifier IC in 2008, while about 70% of Samsung handsets also do so. Motorola and Sony Ericsson seldom adopt independent audio amplifier IC. At present, audio amplifier applied in mobile phone has two development trends: headphone driver amplifier and loudspeaker driver amplifier, which are common configurations to Nokia handsets.
Class-D audio amplifier applied in handsets accounts for more than 50% of the market share, and it mainly has the following types, TPA2010D1, TPA2012D2, TPA2005D1, YDA144, YDA1454, TPA4411, TPA6310A2, and SAPA1D2. New mobile phones, especially Nokia’s new handsets, apply a large amount of Class-D audio amplifiers, and use a pair of amplifiers, one is headphone driver and the other is loudspeaker driver.
