国产蓝牙芯片公司深圳海陵威，做蓝牙芯片;台湾的松翰科技，做PCBA.他们在小家电，医疗领域的芯片都有不错的市场占有率。

早在2005年的时候就介入电子秤行业，当初的电子秤的控制板去到10元左右，芯片大概5元左右，等我离开电子秤领域的时候是2013年，控制板价格降到了2.5元左右，芯片已经跌倒了1.2元，今天和松翰代理聊天才知道，最新的价格已经跌倒了0.3元

原来最早用的是韩国三星的芯片，到台湾富精，松翰为主要供应商，到宏康，再到中国的芯海，芯易德。

价格从15年时间，价格从5元多跌倒0.3元，跌幅高达94%，比一般的传统产品惨烈得多。

中国芯片和其他产品也一样，先从价格入手，抢占市场份额，电子秤芯片在于不仅在打退国外芯片外，还要进行中国内部企业的竞争，而且好像还更残酷，把高端技术产业硬生生的做到一个传统行业的利润。占领市场的同时，也没有太多利润空间去拓展其他领域的市场。

另外一个是蓝牙芯片杰里，在广东珠海。开始一样的，国产芯片不敢用，但价格便宜，做手表手环的时候用进口蓝牙芯片比如Nodic,Ti的，现在也开始试用国产杰里。对比一下，Nodic现在的价格在7块多，而杰里的才2元左右。

最近杰里和小米共同合作开发蓝牙芯片+音频芯片双模芯片，主控芯片+通讯芯片。2019年杰里出货量接近10亿颗。

同样打价格战，杰里开始跨越单一蓝牙搞双模芯片，既能够低价格快速扩展，也能够跨界进入新的市场。

双模芯片，就是把两种芯片结合在一起，竞争最为高端的就是5G双模芯片，华为是佼佼者。
