Electret type: Back electret type provides better low frequency response, but it costs higher.
Dimension: It is difficult to make high sensitivity with the small size. The thinner of the dimension is the higher it costs.
Directivity: Omni-directional type microphone meets most kinds of consuming products, our R&D team will support your special requirement.
Connection: Soldering type, DIP type, and Spring contact type.
Rubber holder: Rubber holder can reduce the interference from the inner machine or from hands touch.

駐極方式 背極式的低頻響應較好,但成本較高.
尺寸大小 尺寸小的靈敏度不易做高.愈薄的會愈貴.
指向性 消費性產品用全指向即可,有特殊需求需與工程人員討論設計上的問題.
接觸方式 分為焊線,DIP,接觸式(彈簧,彈PIN)三種.
Rubber Holder 可以擋掉機器內部,或是人手接觸的磨擦聲音

Echo/ howling: This situation usually happens when a microphone is too close to the speaker or face to the speaker in wrong angle.

Noise signal: The microphone should stay away from any components which might send signal such as antenna and speaker. The cleaner the power source is, the fewer the noise signal is.

Pipe vs. resonance chamber: Limited by the industrial design, it is hard to set microphone near the surface of the case. Therefore we use a pipe to lead the sound, but the frequency response might loss if the length of pipe is too long or the volume is too big.

The directivity: Considering the ventilation of air holes in the back, the closer of the distance between the air holes and the sound hole is, and the straighter the angle is, the better result of directivity is.

Static electricity: FET is very easy to be punctured by static electricity; therefore we need to take measure to prevent it in processing or in transit.

The temp. of ferrochrome: The too high temp. or the too long welding might do damage to the microphone.

Echo/囂叫 當麥克風離喇叭太近,或是角度相對容發生迴授的問題
雜訊 麥克風應遠離天線,喇叭..等會發送信號的零件,電源愈乾淨,雜訊愈小.
導音管vs.音腔大小 因為ID的問題,麥克風的安裝位置往往不能貼近機殼的表面,會以導音管的方式導入聲音,但太長或是容積太大的導音管會使頻響不平(失真).
指向性需知 需注意到背部氣孔透氣的問題,與前音孔愈近,角度愈直,指向性的效果會愈好.
靜電 FET很容易被靜電擊穿,故在加工,運送時,都應有靜電防範的措施.
鉻鐵溫度 鉻鐵的溫度過高,焊接間接太長,都有可能會使麥克風損壞.
