Embodiment Construction

[0011] see figure 1 and figure 2 , the present invention includes a recording and measuring microphone 1, a preamplifier 2, a connecting body 3, a TRRS plug 4 and a TRS socket 5. The back end of the recording and measurement microphone 1 is connected to the front end of the preamplifier 2 , and the back end of the preamplifier 2 is connected to the TRRS plug 4 and the TRS socket 5 through the connecting body 3 . The connecting body 3 is used as the connection, protection and supporting structure between the output end of the preamplifier 2 and the TRRS plug 4 and the TRS socket 5 .

[0012] see image 3 , the output end of the recording or measurement microphone 1 is electrically connected to the input end of the preamplifier 2, the output end of the preamplifier 2 is connected to the S end and the IR end of the TRRS plug 4 through two wires, and the TRS socket 5 The T / R / S ends of the TRRS plug 4 are connected to the T / OR / IR ends of the TRRS plug 4 respectively.

Abstract

A device having recording and microphone test functions and matched with an intelligent terminal for usage comprises a recording or measuring microphone, a preamplifier, a connector, a TRRS plug and a TRS plug port; a rear end of the recording and measuring microphone is connected with a front end of the preamplifier; a rear end of the preamplifier is connected with the TRRS plug and the TRS plug port through the connector; the advantages are that a high end capacitance microphone system is externally connected with the TRRS interface- an audio frequency input / output interface (smart phone, smart flat computer) of an intelligent terminal platform; compared with a pickup of the terminal, the external high end capacitance microphone system is strong in directive property, high in sensitivity, convenient and flexible; the external microphone system can also measure the microphone and cooperate with an acoustics measure software of the terminal so as to carry out field sound field measurement, and is convenient and flexible; the device is small and portable, needs no other periphery equipment besides the intelligent terminal platform, and is 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...
