Microphone used for mobile phone instant speech translation
[0001]

As a result, many peripheral products have been produced, and a microphone external to a
mobile terminal is one of them. However, a typical external microphone for a portable terminal is
often assembled using a plurality of screw fixings in a production assembly process, and the
assembly is complicated and time-consuming. In addition, since each member has a screw fixing
structure, the number of "assembly lines" is relatively large, which affects the appearance of the
product.
[0003]
Furthermore, the microphones of the conventional portable terminal are uni-directional
microphones, many of which are installed in a single direction, and the volume is too large and
the assembly is complicated. Microphones employing a unidirectional microphone unit adjust the
direction of the microphone to achieve the best effect of speech translation when applied to
instant speech translation, and adjust the microphone position to the person recording the
speech The distance between the person who has the need and the person who holds the
portable terminal and the other party of the conversation should not be too far, otherwise the
surrounding noises will easily get in, which affects the quality of the speech translation. However,
even if the distance between the two is too close, it becomes rude to the other party. The
microphone whose volume is too large may block the earphone hole or the speaker hole of the
portable terminal in the process of use, which affects the normal use of the function.
[0004]
The problem to be solved by the present invention is to solve the above-mentioned problems and
reduce the "assembly line" that appears by assembling many members by screw fixing,
beautifying the product appearance and simplifying the production processing process It is an
object of the present invention to provide a microphone used for portable terminal immediate
speech translation, which can achieve clear sound collection.

present invention is a pair of two directional electret condenser microphones, a pair of
microphone covers, an air core tube, a seat body, and an electret condenser PCB assembly. A
plurality of vent holes, a plurality of vent holes, the air core tube, and a plurality of air vents each
including the PCB assembly holding plate, the one set of microphone covers being respectively
