Patent Application
20190069081
The present invention relates to media technologies and more particularly to a microphone technology applicable to a mobile phone technology.
The rapid development of the smart phones and their application software has demonstrated great market outlook and creative potential for mobile devices of the mobile phones to the inventor. Consequently, a diversity of peripheral products are born from such demonstration, with the microphones for mobile phones being one of them.
However, the common microphones for mobile phones mostly have a single directional microphone head provided at one single direction, or are excessively large in their sizes and involve complex production and assembly steps. For the microphone having a single directional head, it is necessary to adjust the direction of the microphone and aim the microphone at a person whose voice needs to be picked up to achieve a better effect for the voice translation when it is applied in the real-time voice translation of embodiments of the present invention, and the distance between the phone holder and the speaker cannot be too far, otherwise the surrounding noises are picked up instead and thus affecting the quality of the voice translation, but it would be impolite if the distance gets too close. Further, an excessively large microphone blocks off the earphone socket or the speaker in some of the phones, and thus affecting the normal use of their functions.
It is therefore obvious that the above-mentioned conventional microphone devices for mobile phones are disadvantageous and are inadequately designed, which urgently require an improvement.
In light of the aforesaid disadvantages, the problems of the prior art are resolved by the embodiments of the travel real-time voice translation microphone for a mobile phone.
An object of this disclosure is to provide a “travel real-time voice translation microphone for a mobile phone” comprising a pair of microphones, a base, a PCB (Printed Circuit Board) component and a pair of enclosing pieces of the PCB component.
Another object is to provide a microphone technology applicable to a mobile phone, and more particularly to a microphone having two different directional microphone heads that are respectively provided at one of two opposing directions, and used in combination with a real-time voice translation software installed in the mobile phone. When the translation software of the mobile phone has been configured to translate a language that requires translation, a user can perform a voice input into the microphone of the mobile phone, and then the voice input will be translated into a language an opposite party is familiar with in real time, so as to achieve a fluent conversation between the user and the opposite party.
In some embodiments, the head that is directed to face a speaker uses a “hypercardioid noise-filtering microphone” for audio pickup and can achieve clear audio pickup within a fixed distance, so as to maintain a socially polite distance from the speaker; the head that is directed to face a phone holder uses a “cardioid noise-filtering microphone” for audio pickup and can achieve a clear audio pickup regardless of how the phone is rotated at certain angles during use, so as to achieve an accurate real-time voice translation on a mobile phone during travelling.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of embodiments disclosed herein.
In order to facilitate better understanding of the aforesaid and other purposes, characteristics and advantages of the apparatus and applications disclosed herein, two embodiments are described and explained. These embodiments are exemplary.

Step 1: placing the PCB component 30 into the right enclosing piece 50 of the PCB component for positioning, and clipping the left enclosing piece 40 of the PCB component into the right enclosing piece 50 of the PCB component;
Step 2: sleeving the component completed in the previous step into the base 20 to fix the components by clipping;
Step 3: evenly applying a glue on the protruding step 22 of the base 20 and sleeving on the microphone cover 10 for adhering, so as to complete assembly of the product.
