FAQ

 Q1. Is it a reliable company?

     Qinyi reply:  Weifang Qinyi Electronic Science and Technology Co.,Ltd is a high technology company which is professional in researching and manufacturing microphones. 
     Our Company has occupied an area of 40 acres and established in the year of 2000,We have got a professional team which possesses strong technical strength and rich practical experiences.

     In recent years,our company has introduced of a series of advanced production equipment.

Q2: What about the delivery?
    reply: we can offer the door to door services by air or by sea, just depend on your actual request. Such as DHL, UPS, TNT, FEDEX… by air; and the sea transportations.

Q3: What’s the delivery time?
    reply: 3 working  days. huge stock.

Q4 :How to choose the microphone?
Directional:  According to the sound receiving range, the microphone is divided into omnidirectional, unidirectional, and noise canceling. The noise canceling microphone is designed to decay the low frequency far. Most customers use omnidirectional microphone; the unidirectional is only used in some special occasions, therefore we should pay more attention to mechanical and circuit design.

Sensitivity: The sensitivity of the microphone affects the recorded volume. However, high sensitivity doesn’t mean a good microphone. The good circuit design is also necessary for getting better results. We suggest selecting a middle common sensitivity at beginning. Too high or too low might affect the lead time and the price.

Test condition: The test voltage and the impedance affect the sensitivity of the microphone. Generally speaking, the higher the voltage and the impedance is the better sensitivity we get. Therefore, the test condition is for reference and IQC only, which is usually different to the reality.

Dimension: Diameter is from 2mm to 14mm, height is from 1.1mm to 6.7mm. 4*1.5, 6*2.2, 6*2.7, 6*5.0, 9.7mm are common spec.

Connecting way: pin, solder pad, SMD. Due to the diaphragm is easily damaged by high temp. during soldering, therefore we suggest finishing the wires and test the microphone again by us to confirm the stability of quality.
