Abstract

A microphone for a vehicle includes an opening configured to disperse wind pressure and a filter configured to prevent vibration due to the wind pressure introduced through the opening. A holder is fixed onto a printed circuit board (PCB) to thereby prevent resonance due to the pressure of the wind passing through the filter, and the PCB is configured to convert a sound wave into an electrical signal.

Claims

1. A microphone for a vehicle, comprising:

an opening configured to disperse wind pressure;

a filter configured to prevent vibration due to the wind pressure introduced through the opening;

a holder fixed onto a printed circuit board (PCB) to thereby prevent resonance due to the wind pressure passing through the filter, wherein

the PCB is configured to convert a sound wave into an electrical signal.

2. The microphone for the vehicle according to claim 1, wherein the opening has a comb shape, the comb shape having a densely arranged plurality of holes.

3. The microphone for the vehicle according to claim 1, wherein the filter is a mesh-shaped filter.

4. The microphone for the vehicle according to claim 1, wherein the holder is a tapered holder, the tapered holder having a hole gradually tapered from one surface to an opposite surface.

5. A microphone for a vehicle, comprising:

an opening configured to disperse wind pressure;

a filter configured to prevent vibration due to the wind pressure introduced through the opening;

a holder fixed onto a printed circuit board (PCB), wherein

the PCB is configured to convert a sound wave into an electrical signal.

6. The microphone for the vehicle according to claim 5, wherein the opening has a comb shape, the comb shape having a densely arranged plurality of holes.

7. The microphone for the vehicle according to claim 5, wherein the filter is a mesh-shaped filter.
