Abstract

A device with recording and microphone testing functions used with an intelligent terminal, including a recording or measuring microphone, a preamplifier, a connector, a TRRS plug and a TRS socket, the back end of the recording and measuring microphone is connected to the front end of the preamplifier, The rear end of the preamplifier is connected with the TRRS plug and the TRS socket through the connecting body. The advantage of the present invention is: through the TRRS interface of the audio input and output interface of the intelligent terminal platform (such as a smart phone, a smart tablet computer, etc.), an external high-grade condenser microphone system is connected. Compared with the terminal's own pickup, the external high-grade condenser microphone system has the characteristics of strong directivity, high sensitivity, convenience and flexibility. The external microphone system can also be used to measure the microphone. With the acoustic measurement software of the terminal, it can conduct on-site sound field measurement, which is convenient and flexible. Small and easy to carry, except for the smart terminal platform, no other peripheral equipment is needed, simple and practical.

Description

technical field

[0001] The invention relates to a device capable of recording and testing a microphone, in particular to a device with the functions of recording and testing a microphone used in conjunction with an intelligent terminal platform. Background technique

[0002] When conducting on-site recording, the reporter needs to carry a dedicated interview microphone and supporting power supply and recording equipment. These equipment are expensive and inconvenient to use, and are not suitable for interviewing emergencies; Use the test analyzer equipped with the measurement microphone at the same time, but the test analyzer is bulky and inconvenient to carry, and it is not suitable for the test and acceptance of the sound field anytime and anywhere. Contents of the invention

[0003] The problem to be solved by the present invention is to provide a portable system that can be used through the TRRS interface of the intelligent terminal platform and can record and test the...
