处于关机状态时，右耳罩与头梁是垂直的。
将右边耳罩旋转九十度，与头梁平行，就能打开耳机了。
打开后，白色LED指示灯会闪烁。
另外，最左边的是降噪开关（红圈），接着从左往右依次是音效切换按钮（蓝圈），LED指示灯（橙圈），USB接口（绿圈），2.5mm耳机线接口（黄圈）。
红圈这里是蓝牙开关，非常小。
默认是打开的，毕竟无线耳机，还是不用线最省事。
这个是语音麦克风，通话的时候，通过这个麦克风采集说话的声音。
两侧耳罩的上下部分，都分别开有一排整齐的小孔，这个就是降噪麦克风，通过它来采集外界的噪音。
说到这里，琛哥来简单科普一下主动降噪耳机的工作原理：原理其实很容易理解，看上面这张图就能明白：降噪耳机内部设置了专门的降噪电路。
通过音频接收器（大多是麦克风）和抗噪芯片来接收和分析外界噪音的频率，并产生与其相反的频率，从而相互减弱或抵消外界噪音。

森海塞尔EW中文使用说明书
森海塞尔E W中文使用说明书Revised final draft November 26, 2020森海塞尔EW100中文使用说明书森海塞尔EW-100系列无线话筒使用方法：发射器使用方法：发射器开关按钮：转动手持话筒底部之保护盖（ON/OFF）位置按（ON/OFF）开关只按钮，直至LED红灯亮（开）。
若要关话筒，程序也是一样。
LED灯亮表示电池量充足，如电池量不足，LED红灯会出现闪烁。
哑音控制（MUTE），使用哑音控制只是将话筒头输出讯号哑音，对接收器并无影响。
方便使用者在调校收发时不会对扩声器材造成破坏。
按（SET）设置按钮。
可选择项目，转换下一项目，按↑是增加数值和选项，按↓是衰减数值和选项.无线话筒（SEnSit）灵敏度调整：演出—30dB/—20dB；一般讲话—20dB/10dB；访问—10dB。
建议演出当中使用（—20dB)。
接收器使用方法：按（POWER）红色按钮开关制。

Sound inlet basket2. XLR-3 connector3. Adjusting the sensitivity4. Adjusting the bass filterInstallationInstallationAttaching the microphoneScrew the microphone clamp to a stand.Place the microphone with its back end into the microphone clamp.Orient the microphone together with the microphone clamp.Connecting the microphoneConnect the XLR-3 socket of the microphone cable (optional accessories) to the XLR-3 socket of the microphone.Using the windshieldPlace the MZW 64 (optional accessories) windshield over the microphone head.OperationPositioning the microphone: Drums / PercussionsAttention: When closing the hi-hat, a strong air current is created on the edge. If the microphone is positioned too close to the edge, interfering noise due to the air current can occur.It is vital to observe the following notes:mentaryA Position the microphone a few centimetres above the outer edge of the hi-hataiming down. If necessary, remove unwanted low-frequency signal portions by highpass filtering.B Good starting position for live miking applications. If the overhead microphones areonly used for picking up the cymbals, unwanted signal portions can be attenuatedby high pass filtering.In order to prevent interference due to crosstalk between adjacent sound sources, try to position the microphone so that the interfering sound source is located in the angle area of the highest can-cellation of the microphone (approx. 180°, see polar diagram).Positioning the monitor loudspeakersTo prevent feedback and crosstalk, postion your monitor loudspeakers in the angle area of the highest cancellation of the microphone (approx. 180°).Sensitivity and bass filterThe e 914 is equipped with a three-position sensitivity switch and a bass filter switch.Adjusting the sensitivityThe microphone sensitvity can remain unchanged (0) or be reduced by 10 dB or 20 dB. The latter is recommended when there is a risk that the microphone or subsequent microphone input is overmo-dulated, e.g. due to high sound pressure levels from drums, brass instruments, etc.We recommend that you mute the corresponding microphone channel on the mixing consolebefore connecting and disconnecting the microphone cable, switching on and off the phantom powering or setting the switches (see figure above).Adjusting the bass filterThe e 914 has been designed for an extended low-frequency bass response. With certain live or close instrument miking applications, an over-emphasis of the low frequencies can occur. This can be compensated for by the 6 dB/octave roll-off filter. The cut-off filter reduces low-frequency wind noise by 18 dB/octave.Cleaning and maintaining the e 914Cleaning and maintaining the e 914CAUTIONLIQUIDS CAN DAMAGE THE ELECTRONICS OF THE PRODUCT!Liquids entering the housing of the product can cause a short-circuit and damage the electronics.Keep all liquids away from the product.Do not use any solvents or cleansing agents.Disconnect the products from the power supply system and remove rechargeable batteries and batteries before you begin cleaning.Clean all products only with a soft, dry cloth.SpecificationsSpecificationsTransducer principle pre-polarised condenser microphone Frequency response 20 - 20,000 Hz Pick-up patterncardioidSensitivity (free field, no load) with pre-attenuation 7 mV/Pa2.3 mV/Pa / 0.7 mV/Pa Nominal impedance (at 1 kHz)100 ΩMin. terminating impedance 1 kΩMax. sound pressure level (at 1 kHz)137/147/157 dB SPL (depending on pre-attenua-tion)Equivalent noise levelA-weighted (DIN IEC 651) CCIR-weighted (CCIR 468-3)19 dB 30 dBPre-attenuation 0 dB, -10 dB, -20 dB Bass filterlinearroll-off 130 Hz, 6 dB/oct.cut-off 85 Hz, 18 dB/oct.Phantom powering 48 V / 2.2 mA Connector XLR-3Dimensions ⌀ 24 x 157 mm Weight198 gPolar pattern30°0°180°150°120°60°90°0510152025dB30°0°180°150°120°60°90°125 Hz 250 Hz 500 Hz 1,000 Hz 2,000 Hz 4,000 Hz8,000 Hz 16,000 HzFrequency responseflat roll offcut off501002005001,0002,0005,00010,00020,000H z0- 10- 20dBOverview of applications Connector assignmentBALANCEDOverview of applicationsPrimary applicationSecondary application。

森海塞尔话筒调节方法
森海塞尔话筒调节方法森海塞尔（Sennheiser）是德国一家世界著名的音频设备制造商，其专业的麦克风产品在音频领域享有很高的声誉。
调节森海塞尔话筒需要细致的操作和理解其性能指标，下面将详细介绍森海塞尔话筒的调节方法。
一、了解森海塞尔话筒的性能指标在调节森海塞尔话筒之前，首先需要了解其性能指标，包括极限声压级、灵敏度、频率响应、指向特性等。
1、极限声压级（Maximum Sound Pressure Level，简称SPL）：指话筒能够承受的最大声压级，过大的声压可能会导致失真。
通常以dB SPL表示。
2、灵敏度（Sensitivity）：指话筒输出信号级别与输入声压级之间的关系。
通常以dBV或mV/Pa表示。
3、频率响应（Frequency Response）：指话筒在不同频率下的输出级别。
通常以特性曲线图的形式表现。
4、指向特性（Polar Pattern）：指话筒在不同方向上的接受声音的能力，常见的有全指向性、心形指向性、超心形指向性等。
二、选择合适的话筒类型1、动圈型话筒：适用于大声音源和高SPL的场景，如乐器放大、现场表演等。
2、静电型话筒：适用于录音室和广播等专业应用场景，具有高灵敏度和平坦的频率响应。
3、电容型话筒：适用于录音室、音乐制作和表演等专业领域，具有高灵敏度和广泛的频率响应。
三、调节森海塞尔话筒的方法在选定合适的话筒后，接下来是需要进行一系列的调节操作，以确保话筒的工作状态和效果。
1、极限声压级的调节：通过控制输入声压级，避免话筒受到过大的声压而发生失真。
首先可以以较低的声压水平进行测试，逐步增加声压，直到感觉到有失真发生即可停止。
2、灵敏度的调节：调节话筒的灵敏度可以通过声卡或混音台的增益调节。
根据实际需求和回放效果，在不引起失真的前提下，适当调节灵敏度，使得声音在回放时能够达到理想的水平。
3、频率响应的调节：根据实际需求和应用场景，可以通过均衡器调节话筒的频率响应。
例如，在录音室中，可以使用均衡器增强低音或高音，以达到更好的效果。
森海塞尔EM-XSW1-35无线话筒说明书
森海塞尔EM-XSW1-35无线话筒说明书森海塞尔EM-XSW1-35无线话筒说明书：森海塞尔EM-XSW1-35无线话筒，由发射和接收两部分组成。
其中，发射部分由电池供电，咪头将声音转换为音频信号，经过内部电路处理，可将音频信息的无线电波发射到周围空间。
接收部分一般是通过电源供电的，首先由接收天线接收到发射部分所发出的无线电波，然后经过内部电路处理，提取音频信号，再通过输出信号线传送到扩音系统中，完成音频信号的无线传输。
了解了无线森海塞尔EM-XSW1-35无线话筒的工作原理，下面再说说在使用无线森海塞尔EM-XSW1-35无线话筒时需要注意哪些问题。
一、注意阻抗匹配无线森海塞尔EM-XSW1-35无线话筒的输出阻抗，与放大器的输入阻抗相同，这就是最佳匹配了。
如果失配比例超过3：1，就会对音频传输效果产生影响，虽然也能用，但高低频的声音都会有明显损失。
二、注意工作距离与近讲效应在手持无线森海塞尔EM-XSW1-35无线话筒讲话或唱歌时，森海塞尔EM-XSW1-35无线话筒与嘴巴之间的工作距离一般在750px-1000px比较合适，距离太远会增加回响，距离太近则会因信号过强导致音频失真，影响清晰度，这就是“近讲效应”，近距离播讲时，低频声会得到明显提高。
当然，近讲效应对声音的影响也不是完全不可取，经验丰富且功底深厚的专业歌唱人士，有时也会专门利用这种效应来改变声音效果。
三、注意声源麦之间的角度无线森海塞尔EM-XSW1-35无线话筒都有一定的有效角度，通常情况下，声源应该尽量对准森海塞尔EM-XSW1-35无线话筒的中心线，因为偏离的角度越大，效果损失就会越大。
四、注意无线麦的摆放位置和高度有时我们开启森海塞尔EM-XSW1-35无线话筒后，会听到尖锐刺耳的声音，这是由于将森海塞尔EM-XSW1-35无线话筒与扬声器放的过近而产生的，拿远一点就没事了。
在使用森海塞尔EM-XSW1-35无线话筒架时，无线森海塞尔EM-XSW1-35无线话筒的高度应该与表演者的嘴巴高度一致，避免过高或过低影响收音效果。

麦克风是谁发明的
麦克风是谁发明的查尔斯斯通(Sir Charles Wheatstone)是"麦克风"这词的始创人，为时 1827年，但即使如此，柏林人埃米贝勒拉(Emile Berliner)在1876年发明了第一个麦克风。
贝勒拉在1951年出生于德国汉诺威。
他19岁到了美国华盛顿。
当时他在库珀学院（现在称为库柏联盟）兼读物理学。
当贝尔在美国百年博览会上推出了首个电话，许多发明家都想改良这一堑新的革命性发明。
贝勒拉尝试找出一种办法可以把声音记录和重复。
最终在1876年，发明了留声机的贝勒拉成功地把麦克风作为电话的话音传送部份。
美国贝尔电话公司后来以50000美元购入贝勒拉了麦克风。
1878年，大卫爱德华休斯(David Edward Hughes)发明了第一支碳麦克风。
1964年，贝尔实验室的韦斯特和西撒拿(James West and Gerhard Sessler)发明了的驻极体传声器(electretmicrophone)。
驻极体传声器体积较小、成本低、精确度及可靠性高。
这发明大大影响今天我们至在用的麦克风。
二1877年3月4日，埃米尔·柏林内尔发明了麦克风。
麦克风是由Microphone音译而来，它是一种能够将声音信号转换为电信号的能量转换器件，也称为话筒、微音器。
麦克风的历史可以追溯到19世纪末，包括贝尔在内的几位科学家致力于寻找更好的拾取声音的办法，用来改进当时的最新发明——电话。
期间，他们发明了液体麦克风和碳粒麦克风。
20世纪，麦克风由最初通过电阻转换声电逐渐发展为电感、电容式转换，新的麦克风技术层出不穷，这其中包括铝带、动圈等麦克风，以及当前广泛使用的电容麦克风和驻极体麦克风。
麦克风的历史可以追溯到19世纪末，贝尔等科学家致力于寻找更好地拾取声音的办法，以用于改进当时的最新发明电话。
期间他们发明了液体麦克风和碳粒麦克风，这些麦克风效果并不理想，只是勉强能够使用。
1949年，威尼伯斯特实验室研制出MD4型麦克风，它能够在嘈杂环境中有效抑制声音回授，降低背景噪音。

当驻极体膜片本身带有电荷，表面电荷地电量为Q，板极间地电容量为C，则在极头上产生地电压U=Q/C，当受到振动或受到气流地摩擦时，由于振动使两极板间的距离改变，即电容C改变，而电量Q 不变，就会引起电压的变化，电压变化的大小，反映了外界声压的强弱，这种电压变化频率反映了外界声音的频率，这就是驻极体传声器地工作原理。
电容式麦克风的膜片多采用聚全氟乙丙烯，其湿度性能好，产生的表面电荷多，受湿度影响小。
