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
The present invention relates to a kind of recording, and device that can measuring microphone, specifically a kind of device with recording, measuring microphone function that coordinates intelligent terminal platform to use.
Background technology
In the time carrying out live recording, reporter need carry special interview microphone and supporting power supply and recording equipment, and these equipment prices are expensive and use inconvenience, are not suitable for accident to interview; When acoustic field at the scene, tester often needs to use and is equipped with supporting measuring and analysing meter with measuring microphone simultaneously and carries out, and measuring and analysing meter volume large, carry inconvenience, be also not suitable for carrying out the test checking and accepting of sound field whenever and wherever possible.
Summary of the invention
Problem to be solved by this invention provides a set of portable can use by the TRRS interface of intelligent terminal platform, can record at the scene and the system of measuring microphone.
Technical scheme of the present invention is: a kind of device with recording and microphone test function that coordinates intelligent terminal to use, it is characterized in that, comprise recording or measuring microphone, preamplifier, connector, TRRS plug and TRS socket, recording and the rear end of measuring microphone and the front end of preamplifier are connected, and the rear end of preamplifier is connected with TRRS plug and TRS socket by connector.
The input of described recording or the output of measuring microphone and preamplifier is electrically connected, the output of preamplifier is connected with IR end with the S end of TRRS plug by two wires, and the T/R/S end of TRS socket is connected with the T/OR/IR end of TRRS plug respectively.
Advantage of the present invention is: by audio frequency input/output interface---the TRRS interface of intelligent terminal platform (as smart mobile phone, Intelligent flat computer etc.), external high-grade condenser microphone system.External high-grade condenser microphone system has strong, highly sensitive, the convenient, flexible characteristic of directive property compared with the pick-up of terminal itself.External microphone system also can be used for measuring microphone, coordinates the acoustic measurement software of terminal, can carry out on-the-spot acoustic field, convenient, flexible.
On intelligent terminal platform, use this present invention and coordinate software, the audio sound-recording that carries out high-quality that can be at any time and the acoustical testing of degree of precision.Small and exquisite being easy to carry, except intelligent terminal platform, no longer needs other peripheral equipment, simple and practical.

Embodiment
Referring to Fig. 1 and Fig. 2, the present invention includes recording and measuring microphone 1, preamplifier 2, connector 3, TRRS plug 4 and TRS socket 5.The rear end of recording and measuring microphone 1 is connected with the front end of preamplifier 2, and the rear end of preamplifier 2 is connected with TRRS plug 4 and TRS socket 5 by connector 3.Junctor 3 is as being connected of the output of preamplifier 2 and TRRS plug 4 and TRS socket 5, protection and supporting construction repeatedly.
Referring to Fig. 3, the input of the output of described recording or measuring microphone 1 and preamplifier 2 is electrically connected, the output of preamplifier 2 is connected with IR end with the S end of TRRS plug 4 by two wires, and the T/R/S end of TRS socket 5 is connected with the T/OR/IR end of TRRS plug 4 respectively.
The present invention is in the time of work, and acoustical signal is converted into the signal of telecommunication by recording and measuring microphone 1, by preamplifier 2, signal transferred to TRRS plug 4 by connector 3, and export intelligent terminal platform to by TRRS plug 4; The output signal of intelligent terminal platform transfers to connector 3 through TRRS plug 4 simultaneously, finally exports outside sound amplifier to by TRS socket 5.
Innovative point of the present invention is that the microphone system being connected with intelligent terminal platform by TRRS interface can provide high-quality recording or acoustic measurement function; And all right integrated stereo output interface of TRS of this microphone system, exports the audio output signal of intelligent terminal platform to outside sound amplifier by the stereo output interface of TRS of microphone system.
