<c.captionstyle>下面，我们有请Tokui先生为我们讲解。</c>

00:01:16.020 --> 00:01:21.017 align:middle line:100%
<c.captionstyle>接下来由我为大家介绍TDK的新型无线充电印刷线圈。</c>

00:01:21.033 --> 00:01:26.000 align:middle line:100%
<c.captionstyle>细说之前，我们先来了解它的3大特点。</c>

00:01:26.013 --> 00:01:32.000 align:middle line:100%
<c.captionstyle>其一是纤薄外形设计；其二降低了辐射噪音；其三增加了NFC技术。</c>

00:01:32.037 --> 00:01:34.013 align:middle line:100%
<c.captionstyle>接下来让我们深入了解产品细节。</c>

00:01:37.073 --> 00:01:42.073 align:middle line:100%
<c.captionstyle>目前TDK为各种产品开发无线充电线圈。</c>

00:01:43.027 --> 00:01:49.053 align:middle line:100%
<c.captionstyle>在这里，我们将以车载手机充电线圈为例，为各位展开阐述。</c>

00:01:52.067 --> 00:01:56.000 align:middle line:100%
<c.captionstyle>近年来，越来越多用户选择车载“无线充电”。</c>

00:01:56.093 --> 00:01:59.030 align:middle line:100%
<c.captionstyle>请各位看这里，这是智能手机充电器的示意图。</c>

00:01:59.090 --> 00:02:03.070 align:middle line:100%
<c.captionstyle>里面包含了线圈和控制电路板。</c>

00:02:06.017 --> 00:02:10.097 align:middle line:100%
<c.captionstyle>TDK生产的就是这些线圈元件。</c>

00:02:13.097 --> 00:02:19.007 align:middle line:100%
<c.captionstyle>这次TDK开发的线圈和传统产品不同，是一款纤薄型印刷线圈。</c>

00:02:19.077 --> 00:02:24.073 align:middle line:100%
<c.captionstyle>新型印刷线圈的厚度约为传统产品的五分之一。</c>

00:02:27.020 --> 00:02:31.050 align:middle line:100%
<c.captionstyle>另外，过去必须将3个传统绕组线圈整合在一起才能填充所需充电区域，</c>

00:02:31.090 --> 00:02:34.087 align:middle line:100%
<c.captionstyle>而新型印刷线圈采用独特的形状设计，</c>

00:02:34.087 --> 00:02:38.000 align:middle line:100%
<c.captionstyle>只需单个线圈即可覆盖整个充电区域。</c>

00:02:42.043 --> 00:02:47.057 align:middle line:100%
<c.captionstyle>更少的控制线圈，意味着能显著缩小电路板的尺寸。</c>

00:02:52.037 --> 00:02:58.070 align:middle line:100%
<c.captionstyle>我们演播室特意准备了实物样品，请您介绍一下。</c>

00:02:58.070 --> 00:03:03.023 align:middle line:100%
<c.captionstyle>这个是传统绕组线圈，厚度为3.8mm。</c>

00:03:03.097 --> 00:03:10.010 align:middle line:100%
<c.captionstyle>相比之下，新型印刷线圈的厚度是传统线圈的五分之一。</c>

00:03:12.083 --> 00:03:14.023 align:middle line:100%
<c.captionstyle>现在让我们拿起来对比看一下。</c>

00:03:15.027 --> 00:03:21.090 align:middle line:100%
<c.captionstyle>新型线圈厚度0.73mm，看起来比信用卡还要薄。</c>

00:03:21.090 --> 00:03:26.003 align:middle line:100%
<c.captionstyle>透过直播画面，大家是否能感受到它的纤薄？</c>

00:03:26.003 --> 00:03:28.093 align:middle line:100%
<c.captionstyle>真的，薄如蝉翼。</c>

00:03:28.093 --> 00:03:31.007 align:middle line:100%
<c.captionstyle>Tokui先生，</c>

00:03:31.007 --> 00:03:33.053 align:middle line:100%
<c.captionstyle>它的厚度差不多就跟纸张一样，对么？</c>

00:03:35.037 --> 00:03:41.037 align:middle line:100%
<c.captionstyle>但这么薄的线圈能用来充电吗？</c>

00:03:41.057 --> 00:03:44.017 align:middle line:100%
<c.captionstyle>您能为我们演示一下吗？</c>

00:03:46.040 --> 00:03:50.010 align:middle line:100%
<c.captionstyle>这个充电器，里面用的就是这种印刷线圈。</c>

00:03:50.017 --> 00:03:54.070 align:middle line:100%
<c.captionstyle>现在让我们用这个充电器演示一番。</c>

00:03:55.097 --> 00:04:01.017 align:middle line:100%
<c.captionstyle>好的，我们看到Tokui先生从口袋里拿出了手机。</c>

00:04:02.003 --> 00:04:07.093 align:middle line:100%
<c.captionstyle>好的，我们看到Tokui先生从口袋里拿出了手机。</c>

00:04:08.020 --> 00:04:12.047 align:middle line:100%
<c.captionstyle>充电开始时，它会变成绿色。</c>

00:04:12.047 --> 00:04:14.010 align:middle line:100%
<c.captionstyle>现在让我们把手机放到充电器上，看看效果。</c>

00:04:14.053 --> 00:04:16.000 align:middle line:100%
<c.captionstyle>直播画面。</c>

00:04:16.000 --> 00:04:18.053 align:middle line:100%
<c.captionstyle>请各位仔细看。</c>

00:04:19.053 --> 00:04:25.030 align:middle line:100%
<c.captionstyle>像这样，屏幕的颜色变为绿色的时候，说明充电已经开始了。</c>

00:04:26.053 --> 00:04:30.093 align:middle line:100%
<c.captionstyle>是的，现在手机屏幕一直保持绿色，说明正在充电，对吧？</c>

00:04:31.057 --> 00:04:37.087 align:middle line:100%
<c.captionstyle>但是Tokui先生，用无线充电的时候很难固定手机位置，</c>

00:04:37.087 --> 00:04:41.080 align:middle line:100%
<c.captionstyle>通常手机位置会发生偏位，对吧？尤其在车载使用的时候。</c>

00:04:41.080 --> 00:04:44.013 align:middle line:100%
<c.captionstyle>确实存在这个可能。</c>

00:04:45.003 --> 00:04:49.083 align:middle line:100%
<c.captionstyle>偏位的话是不是就不能充电了？</c>

00:04:49.083 --> 00:04:50.043 align:middle line:100%
<c.captionstyle>可以么？</c>

00:04:50.070 --> 00:04:54.020 align:middle line:100%
<c.captionstyle>关于这一点，大可放心！我们的印刷线圈采用了独特形状设计，</c>

00:04:54.020 --> 00:04:57.083 align:middle line:100%
<c.captionstyle>即使发生偏位也能继续充电。</c>

00:04:57.083 --> 00:05:03.070 align:middle line:100%
<c.captionstyle>那我们偏移一下手机，看看实际情况如何？</c>

00:05:03.087 --> 00:05:14.093 align:middle line:100%
<c.captionstyle>你看，就算手机像这样偏离线圈中心位置，充电也不会受到影响的。</c>

00:05:16.077 --> 00:05:24.040 align:middle line:100%
<c.captionstyle>大家请看，即使偏位，手机充电仍然不受影响，屏幕一直保持绿色。</c>

00:05:24.087 --> 00:05:26.023 align:middle line:100%
<c.captionstyle>Tokui先生，谢谢您。</c>

00:05:26.077 --> 00:05:32.093 align:middle line:100%
<c.captionstyle>接下来您能结合实际案例，为我们详细阐述技术方面的内容吗。</c>

00:05:33.050 --> 00:05:36.040 align:middle line:100%
<c.captionstyle>好的，我们继续。</c>

00:05:37.030 --> 00:05:39.033 align:middle line:100%
<c.captionstyle>接下来我们来介绍车载方面的实际应用案例。</c>

00:05:39.077 --> 00:05:44.077 align:middle line:100%
<c.captionstyle>充电区域能覆盖大尺寸手机。</c>

00:05:46.007 --> 00:05:50.053 align:middle line:100%
<c.captionstyle>当然也能同时满足小尺寸手机的充电需求，</c>

00:05:51.013 --> 00:05:54.073 align:middle line:100%
<c.captionstyle>但是小尺寸手机充电的时候，位置有可能会偏离线圈中心。</c>

00:05:55.020 --> 00:05:57.037 align:middle line:100%
<c.captionstyle>不过，这并不妨碍其正常充电。</c>

00:05:57.070 --> 00:06:02.030 align:middle line:100%
<c.captionstyle>另外，新型印刷线圈即使在最恶劣的条件下，</c>

00:06:02.073 --> 00:06:06.047 align:middle line:100%
<c.captionstyle>线圈元件温升也不会超过20℃。</c>

00:06:10.063 --> 00:06:13.043 align:middle line:100%
<c.captionstyle>接下来是和传统绕组线圈的充电效率的比较。</c>

00:06:13.050 --> 00:06:16.097 align:middle line:100%
<c.captionstyle>对于传统绕组线圈，手机位置不佳会导致充电效率降低，</c>

00:06:16.097 --> 00:06:18.097 align:middle line:100%
<c.captionstyle>可能降低至正常充电水平的65%。</c>

00:06:18.097 --> 00:06:26.037 align:middle line:100%
<c.captionstyle>相比而言，新型印刷线圈的充电效率最多降至71%，提高了6%。</c>

00:06:26.067 --> 00:06:31.003 align:middle line:100%
<c.captionstyle>这有助于客户较少充电模块中冷却系统的尺寸。</c>

00:06:32.087 --> 00:06:35.037 align:middle line:100%
<c.captionstyle>另外说一下，无线充电系统中还存在一个难题，</c>

00:06:35.037 --> 00:06:39.003 align:middle line:100%
<c.captionstyle>即无意发射的电磁噪音辐射。</c>

00:06:43.007 --> 00:06:46.090 align:middle line:100%
<c.captionstyle>这个是传统绕组线圈的辐射噪音测量结果。</c>

00:06:46.090 --> 00:06:50.087 align:middle line:100%
<c.captionstyle>可以看到，辐射噪音频率范围很广。</c>

00:06:52.090 --> 00:06:59.077 align:middle line:100%
<c.captionstyle>因此，TDK专门开发了一种能贴在印刷线圈表面的EMC屏蔽罩（电磁屏蔽罩）。</c>

00:06:59.090 --> 00:07:03.090 align:middle line:100%
<c.captionstyle>这能有效抑制辐射噪音。</c>

00:07:07.027 --> 00:07:13.007 align:middle line:100%
<c.captionstyle>近年来，智能手机和汽车之间的通信需求不断增加。</c>

00:07:17.020 --> 00:07:23.070 align:middle line:100%
<c.captionstyle>为了实现NFC功能，充电线圈上面需要放置一个NFC芯片。</c>

00:07:23.070 --> 00:07:29.083 align:middle line:100%
<c.captionstyle>但如果线圈和NFC芯片重叠放的话，则会增加厚度。</c>

00:07:31.003 --> 00:07:37.000 align:middle line:100%
<c.captionstyle>因此，TDK采用了充电线圈和NFC天线并排放置的形式，</c>

00:07:37.020 --> 00:07:39.077 align:middle line:100%
<c.captionstyle>实现了更纤薄的外形。</c>

00:07:41.080 --> 00:07:46.000 align:middle line:100%
<c.captionstyle>最后，我们回顾总结上面介绍的新型印刷线圈的特点。</c>

00:07:46.040 --> 00:07:49.000 align:middle line:100%
<c.captionstyle>主要有3个特点。</c>

00:07:49.000 --> 00:07:51.013 align:middle line:100%
<c.captionstyle>第一，极为纤薄。</c>

00:07:51.063 --> 00:07:54.010 align:middle line:100%
<c.captionstyle>第二，能减少噪音辐射。</c>

00:07:54.020 --> 00:07:59.053 align:middle line:100%
<c.captionstyle>第三，NFC芯片和线圈并排放置。</c>

00:07:59.067 --> 00:08:02.000 align:middle line:100%
<c.captionstyle>以上就是新产品的说明。</c>

00:08:02.090 --> 00:08:03.083 align:middle line:100%
<c.captionstyle>谢谢。</c>

00:08:04.040 --> 00:08:08.000 align:middle line:100%
<c.captionstyle>不仅外形纤薄，而且实实在在地融入了各项技术，</c>

00:08:08.027 --> 00:08:12.030 align:middle line:100%
<c.captionstyle>是真真切切地取得了发展进步。</c>

00:08:13.023 --> 00:08:14.003 align:middle line:100%
<c.captionstyle>谢谢。</c>

00:08:14.043 --> 00:08:19.093 align:middle line:100%
<c.captionstyle>那么接下来请允许我问您几个问题。</c>

00:08:20.080 --> 00:08:22.060 align:middle line:50%
<c.captionstyle>是从观众那里收集来的，</c>

00:08:23.000 --> 00:08:24.010 align:middle line:50%
<c.captionstyle>具有代表性的问题。</c>

00:08:25.000 --> 00:08:27.020 align:middle line:50%
<c.captionstyle>第一个问题，</c>

00:08:27.043 --> 00:08:35.007 align:middle line:50%
<c.captionstyle>线圈变薄后，是否会导致发热增加或效率降低呢？</c>

00:08:35.013 --> 00:08:36.043 align:middle line:50%
<c.captionstyle>我也很好奇，</c>

00:08:36.057 --> 00:08:37.073 align:middle line:50%
<c.captionstyle>究竟会不会？</c>

00:08:38.003 --> 00:08:42.037 align:middle line:50%
<c.captionstyle>关于这个问题，大家大可放心。</c>

00:08:42.067 --> 00:08:46.003 align:middle line:50%
<c.captionstyle>我们的印刷线圈采用了独特的形状设计，即使电流很小也能支持充电。</c>

00:08:46.003 --> 00:08:52.033 align:middle line:50%
<c.captionstyle>也就是说因为效率得到提升，所以没有方面的担心，对吧。</c>

00:08:52.053 --> 00:08:56.067 align:middle line:100%
<c.captionstyle>如果是以前的线圈，即我们所说的传统绕组线圈，</c>

00:08:56.067 --> 00:09:04.090 align:middle line:100%
<c.captionstyle>是很难做出这种形状的，这也是印刷线圈的独特之处。</c>

00:09:05.093 --> 00:09:06.087 align:middle line:100%
<c.captionstyle>谢谢。</c>

00:09:06.087 --> 00:09:09.013 align:middle line:100%
<c.captionstyle>大可放心！</c>

00:09:09.023 --> 00:09:10.027 align:middle line:61%
<c.captionstyle>好的，我们继续。</c>

00:09:10.063 --> 00:09:14.050 align:middle line:61%
<c.captionstyle>请问产品的应用仅限于车载领域吗？</c>

00:09:14.070 --> 00:09:16.067 align:middle line:61%
<c.captionstyle>虽然我们刚刚介绍的都是关于车载智能手机充电方面的应用，</c>

00:09:16.067 --> 00:09:17.090 align:middle line:61%
<c.captionstyle>但其实无线充电线圈并不仅限于车载应用，</c>

00:09:17.090 --> 00:09:33.017 align:middle line:61%
<c.captionstyle>在我们身边也有很多地方能用到。</c>

00:09:33.030 --> 00:09:39.020 align:middle line:61%
<c.captionstyle>我们能将其扩展到其他领域，这里演示的只是其中一个代表实例。</c>

00:09:40.013 --> 00:09:41.090 align:middle line:61%
<c.captionstyle>我很期待。</c>

00:09:42.043 --> 00:09:45.023 align:middle line:100%
<c.captionstyle>接下来是最后一个问题了。</c>

00:09:47.033 --> 00:09:50.073 align:middle line:61%
<c.captionstyle>请问充电区域具体是多大呢？</c>

00:09:52.003 --> 00:09:55.090 align:middle line:61%
<c.captionstyle>正如我们前面的演示中说到的，通常线圈大小基于一台手机尺寸来设定的。</c>

00:09:55.090 --> 00:09:57.040 align:middle line:61%
<c.captionstyle>但我们能通过增加线圈数量、改变印刷图案形状等方式来扩大充电区域，</c>

00:09:58.033 --> 00:10:08.077 align:middle line:61%
<c.captionstyle>所以对于大范围的充电区域要求，我们同样能满足。</c>

00:10:08.087 --> 00:10:16.087 align:middle line:100%
<c.captionstyle>正如我前面提到的，因为新型线圈是印刷制作的，这很容易实现。</c>

00:10:17.030 --> 00:10:20.097 align:middle line:100%
<c.captionstyle>好的，谢谢Tokui先生。</c>

00:10:21.020 --> 00:10:27.047 align:middle line:100%
<c.captionstyle>可能有一些观众希望能向主讲人单独提问。</c>

00:10:27.047 --> 00:10:32.057 align:middle line:100%
<c.captionstyle>这次我们设置了一个能向主讲人单独提问的聊天功能。</c>

00:10:33.077 --> 00:10:35.007 align:middle line:100%
<c.captionstyle>通过这个按键就能实现。</c>

<c.captionstyle>好的，首先如之前演示中介绍的，</c>

00:11:30.063 --> 00:11:31.087 align:middle line:100%
<c.captionstyle>我们之前主要是面向车载方面开发了这款元件，</c>

00:11:31.087 --> 00:11:36.043 align:middle line:100%
<c.captionstyle>但我们TDK接下来也希望进一步拓展其应用范围，</c>

00:11:36.043 --> 00:11:50.007 align:middle line:100%
<c.captionstyle>因此未来我们将推进其他领域的开发应用。</c>

00:11:51.033 --> 00:11:52.057 align:middle line:100%
<c.captionstyle>谢谢Tokui先生。</c>

00:11:52.080 --> 00:11:56.023 align:middle line:100%
<c.captionstyle>时间过得很快，本次直播很快就接近尾声了。</c>

00:11:56.030 --> 00:11:59.007 align:middle line:100%
<c.captionstyle>不过从3点开始，大家还能利用聊天功能和Tokui先生交流。</c>

00:11:59.007 --> 00:12:08.023 align:middle line:100%
<c.captionstyle>Tokui先生，节目最后您再和观众说几句，可以吗？</c>

00:12:11.027 --> 00:12:16.050 align:middle line:100%
<c.captionstyle>通过演示等方式介绍线圈，可能有些部分比较容易理解，</c>

00:12:16.050 --> 00:12:20.073 align:middle line:100%
<c.captionstyle>也可能有些部分不好理解，时间比较短暂，</c>

00:12:20.073 --> 00:12:29.017 align:middle line:100%
<c.captionstyle>所以如果各位对这些部分有任何疑问，欢迎积极提问。</c>

00:12:29.017 --> 00:12:30.003 align:middle line:100%
<c.captionstyle>谢谢您。</c>

00:12:30.030 --> 00:12:31.030 align:middle line:100%
<c.captionstyle>谢谢。</c>

00:12:32.033 --> 00:12:42.017 align:middle line:100%
<c.captionstyle>超薄厚度，仅为0.73毫米，并且充电范围更广。您心动了吗？</c>

00:12:42.037 --> 00:12:45.033 align:middle line:100%
<c.captionstyle>敬请期待我们后续的开发成果。</c>

00:12:45.073 --> 00:12:47.023 align:middle line:100%
<c.captionstyle>谢谢各位，我是Tokui。</c>

00:12:47.027 --> 00:12:48.097 align:middle line:100%
<c.captionstyle>非常感谢。</c>

00:12:51.077 --> 00:13:01.023 align:middle line:45%
<c.captionstyle>之后从15：25开始，我们将直播介绍µPOL电源模块。</c>

00:13:01.023 --> 00:13:06.060 align:middle line:45%
<c.captionstyle>我们同样设置了问答环节，欢迎各位积极提问。</c>

00:13:06.067 --> 00:13:11.077 align:middle line:100%
<c.captionstyle>接下来，大家有时间也可关注TDK网站上的资讯。</c>

00:13:11.077 --> 00:13:14.050 align:middle line:100%
<c.captionstyle>非常感谢。</c>
