麦克风
麦克风麦克风是我们生活中常见但又极为重要的一种设备。
它能够将声音转化为电信号，并通过电缆或无线传输给其他设备进行录制、放大或传输。
麦克风广泛应用于语音通信、音频录制、音乐演奏等领域，并且在现代科技的发展中扮演着重要的角色。
麦克风的原理是利用声音振动产生的声波，通过振动膜片使磁场发生变化，进而通过线圈感应出电信号。
这个过程涉及到声音的变换、振动的传递和电信号的转换。
麦克风的种类很多，常见的有电容式麦克风、动圈式麦克风、指向性麦克风等。
电容式麦克风是一种常见的麦克风类型。
它利用了振动膜片与固定电极之间的电容变化来接收声音。
当声音通过麦克风时，膜片会受到声波的振动，从而使得电容的大小发生变化。
这种变化会被电路转化为电信号并输出。
电容式麦克风具有高灵敏度、广泛的频率响应和较低的失真程度的特点，使其在音频录制和演唱会等场合中得到广泛应用。
动圈式麦克风是另一种常见的麦克风类型。
它利用了线圈在磁场中运动产生的感应电流来接收声音。
在动圈式麦克风中，声音传递到膜片时，膜片与线圈连接在一起并固定于磁场中。
当声音通过麦克风时，膜片会受到声波的振动，从而使得线圈在磁场中运动。
运动的线圈会产生感应电流，并通过电路输出。
动圈式麦克风具有坚固耐用、抗冲击和高音质的特点，广泛应用于舞台演出和录制音乐等领域。
除了常见的电容式和动圈式麦克风，还有一些其他类型的麦克风，如指向性麦克风。
指向性麦克风能够根据声音传播的方向性选择感应声音，并屏蔽其他方向的声音。
这使得指向性麦克风在会议记录和新闻采访等场合中非常有用。
麦克风在不同领域有着广泛的应用。
在通讯领域，麦克风用于电话、无线电和对讲机等设备中，为人们提供清晰的语音传输。
在音频录制领域，麦克风是录音棚和现场音乐演出的必备工具，通过精确捕捉声音来创作和演绎音乐。
在语音识别技术中，麦克风广泛用于将人类的语音信号转化为计算机可以理解的数据，推动了人机交互和智能助手的发展。
随着科技的不断进步，麦克风的发展也在不断演进。

The frequency response is tailored for wide-range sound reproduction with very natural sound pickup for either distant or close-up use. The PC Desktop can be used on lecterns, podiums, desks, table-tops, or other applications. To maximize gain-before-feedback, the PolarChoice’s three directional polar patterns allow the user to pick the directional polar pattern for optimum effect. For those applications where gain-before feedback is not a problem, anomnidirectional pattern is included. Applications requiring speaking close to the microphone at podiums, lecterns, or pulpits normally require a windscreen (included) to control breath noise and P-popping or, in some cases, wind noise from circulating air.Microphone Setup:Refer to Figure 1 for the following switch function descriptions-Switch “A”:Select High-Pass switch position. Start with this switch set to the left (flat response). If the mic is in a location where low frequency rumble or wind noise is a encountered, moving this switch to the right will help by reducing low frequency sensitivity. Flat ( ): Normal response.High Pass ( ): minimum 5 dB reduction in sensitivity at 100 Hz.Switch “B”:Select preferred polar pattern. The cardioid polar pattern works well for most installations. If feedback from a sound system occurs, switching to the supercardioid or hypercardioid pattern will usually allow increased mic gain before feedback. The omnidirectionalpattern is best suited for situations where there is no sound reinforcement system present, such as for recording.Switch “C” and “D”:Controls action of push-button switch on the top of the PC Desktop microphone.Momentary Modes:When switch “C” is set to the left, the push-button (mute) switch action is momentary.In addition, If switch “D” is in the left hand position, the mic willbe in push-to-mute mode.Alternately, If switch “D” is in the right hand position, the mic will be in push-to-talk mode.Toggle Modes:When switch “C” is in the right hand position, the push-button (mute) switch will be in toggle (push-on/push-off) mode.With switch “C” in the right hand position, the setting of switch “D” determines if the mic audio should be muted when power is first applied.If switch “D” is in the left hand position, the mic audio will be on when power is first applied.If switch “D” is in the right hand position, mic audio will be muted when power is first applied.Switch “E” (Logic Mode Select):When switch “E” is set in the left hand position, the PC Desktopoperates as a normal desk microphone. Mic muting and operation of the LED is controlled by the push-button on the top of the mic. With switch “E” in the right hand position, the mic will be in automatic mixer mode, and the following will apply:1.) Mic audio is always on.2.) The automatic mixer controls LED operation and micmuting.Wiring:For non-automatic mixer applications, the PC Desktop comes equipped with a standard XLR style 3-pin male connector. Forautomatic mixer applications, remove the XLR connector and service the cable as needed.Cable Connections:Red – Balanced Audio High Black – Balanced Audio Low Shield – Audio GroundGreen – Logic Ground (Common to shield unless R45 is removed. See Figure 3.)White – Switch Logic Orange – LED ControlLogic Signals:If the PC desktop mic is in momentary mode (see above section on the mute switch), the logic level on the white wire will normally be “high”, and go “low” when the push-button is pressed. If the mute switch is set for toggle mode, the logic will toggle from high to low, or from low to high, each time the button is pressed. (If desired, a pc board change can be done to force the logic to always be momentary, regardless of switch settings. See Figure 3).LED Control:When the mic is in automatic mixer mode, a low logic signal on the orange LED control wire will cause the LED to light.Logic Ground Lift:If necessary, the logic and audio grounds can be separated. This requires removing a resistor from the pc board.

麦克风种类及运作原理
麦克风种类及运作原理麦克风种类及运作原理麦克风是一种将声音信号转换成电信号的设备，它是现代通信技术中不可缺少的一部分。
麦克风的种类很多，并且可以根据不同的应用需求进行选择。
下面将介绍几种常见的麦克风类型及其运作原理。
1. 电容式麦克风电容式麦克风是一种需要外部电源供电的麦克风。
它利用电容的原理将声音信号转换成电信号。
当声波进入麦克风时，声波会引起麦克风内部的电容板振动，从而改变电容器的电容量，进而改变电路中的电荷量。
这些电荷量的变化反映了声音信号的变化，最终被放大和处理。
电容式麦克风通常用于录音和广播应用中，由于其高质量的输出和灵敏度，是专业录音棚和工作室中常见的类型。
2. 动圈式麦克风动圈式麦克风是一种常用的麦克风类型，广泛用于演唱、话筒和音频记录应用。
它的原理是利用感应原理，通过沿着磁场振动的金属线圈来转换声音信号。
金属线圈固定在主体底部的磁铁周围，并且当声波进入麦克风时产生的振动引起金属线圈的运动。
这些运动产生一个微弱的电流，通过线圈和磁铁之间的感应产生电信号。
动圈式麦克风因为其坚固和可靠性而广泛应用于音频行业，因为它们可以承受很高的噪声水平和振动。
3. 现场反射型麦克风现场反射型麦克风是一种利用声波反射原理的麦克风。
这种麦克风可以安装在表面上，例如墙壁、天花板和地板等。
当人们说话或演唱时，声源的声音将反射进麦克风，然后被转换成电信号。
现场反射型麦克风在会议室、教室、演播室和音乐厅等场合广泛应用，可以提供优质的声音采集和传输效果。
4. 阵列麦克风阵列麦克风是一种多元素麦克风，具有精确的方向性功能。
它们提供全向性、双向性、心形和超心形模式，在不同的应用场合下可以选择不同的模式，以改善音频质量。
阵列麦克风使用多个小型麦克风的阵列排列来改变声源的反射角度，进而扭曲声音和减少噪音。
阵列麦克风在会议、讲座和语音识别系统中广泛应用。
总结麦克风是音频行业中必不可少的组件，不同的麦克风类型适合不同的应用需求。
关于麦克风的参数介绍-驻极体麦克风（ECM）和硅麦（MEMS）
关于麦克风的参数介绍-驻极体麦克风（ECM）和硅麦（MEMS）1、麦克风的分类1.1、动圈式麦克风（Dynamic Micphone）原理：基本构造包含线圈、振膜、永久磁铁三部分。
当声波进⼊麦克风，振膜受到声波的压⼒⽽产⽣振动，与振膜在⼀起的线圈则开始在磁场中移动，根据法拉第的楞次定律，线圈会产⽣感应电流。
特性：动圈式麦克风因含有磁铁和线圈，不够轻便、灵敏度较低、⾼低频响应表现较差；优点是声⾳较柔润，适合⽤来收录⼈声。
应⽤：KTV场所。
1.2、电容式麦克风（Condenser Micphone）原理：根据电容两⽚隔板间距离的改变来产⽣电压变化。
当声波进⼊麦克风，振膜产⽣振动，使得振动膜和基板之间的距离会随着振动⽽改变，于是基板间的电容会变，根据Q=C*V（电容式麦克风中电容极板的电压会维持⼀个定值）得到变化的电荷量Q。
特性：灵敏度⾼，常⽤于⾼质量的录⾳。
应⽤：消费电⼦、录⾳室。
1.3、铝带式麦克风（Ribbon Micphone）原理：在磁铁两极间放⼊通常是铝制的波浪状⾦属箔带，⾦属薄膜受声⾳震动时，因电磁感应⽽产⽣信号。
1.4、碳精麦克风（Carbon Micphone）2、两种常⽤电容式麦克风的对⽐：驻极体电容麦克风（ECM）和微机电麦克风（MEMS Micphone）2.1、驻极体电容麦克风（Electret Condenser Micphone）原理：驻极体麦克风使⽤了可保有永久电荷的驻极体物质，不需要再对电容供电。
（若驻极体麦克风中内置放⼤电路，则需要供电）优点：技术成熟、价格便宜缺点：体积⼤，不⽅便SMT、引线长，造成信号衰减、⽣产⼯序多，⼀致性差、灵敏度不稳定2.2、微机电麦克风（MEMS Micphone）原理：微机电麦克风也称麦克风芯⽚或硅麦克风，硅麦⼀般都集成了前置放⼤器，甚⾄有些硅麦会集成模拟数字转换器，直接输出数字信号，成为数字麦克风。
优点：体积⼩，可SMT、产品稳定性好缺点：价格较⾼备注：⼀般情况下，我们把集成了前置放⼤器或者模拟数字转换器的麦克风称为拾⾳器（pickup）。
