Abstract

A sound pick-up device comprises a sound pick-up and a lead wire thereof, wherein the lead wire is composed of a multi-core wire harness, and is characterized in that the lead wire is connected with a butt joint interface, and the corresponding relation between a contact in the butt joint interface and each contact of the sound pick-up is set according to the specific requirements of a customer, so that the later-period wire harness is used for butt joint connection. The utility model has the advantages that: in normal use, the power supply and the signal transmission of the whole equipment can be completed by using the universal multi-strand wire harness. The general terminal equipment has a power supply and signal acquisition port, and can provide power supply and transmit signals by only connecting a wire harness. Simultaneously, every pickup apparatus contains two ports, when many pickups use, can adopt general strand to establish ties, alright supply power and signal acquisition to many pickups, realize that a pickups supplies power, and the pickups in the whole link all can obtain the application of power supply work.

Description

Sound pick-up device

Technical Field

The utility model relates to a pickup device.

Background

With the popularity of video networks nowadays, video surveillance is involved in a wider and wider range, almost in every corner where it is needed. With the improvement of the monitoring requirement, the image definition of the monitoring video is greatly improved, and the requirement on the tone quality is higher and higher. Audio and video synchronization will become a necessary requirement for future monitoring systems.

A large number of microphone arrangements for audio acquisition are now emerging on the market. Typically the device is of a three-wire or four-wire system; including the positive and negative poles of the power supply and the positive and negative poles of the audio output. In normal use, the sound pick-up needs to be powered, and the audio signal output is connected to the input end of the transmission or recording equipment. Therefore, conventional microphone products generally require a small section of bare wire to be reserved for power connection and signal extraction in a specific use scenario.

The pick-up with the structure needs to separately manufacture a power line and an audio connecting line when in normal use, and needs to peel off the wire end and then adopts a tool to connect. The connection mode is that the work amount is relatively large, and the processing and manufacturing of the wire (stripping of the wire skin) are required on a construction site; secondly, the reliability is poor, a special tool is needed for protection after the wire rod is connected, meanwhile, the butt joint of the line definition information cannot be wrong, and otherwise, the equipment cannot be used normally.

Meanwhile, if a plurality of sound pick-up devices are needed in a certain area for sound pick-up, power supply and signal output are required to be carried out on each sound pick-up device, a large amount of wires, manpower and equipment are consumed for the use of each sound pick-up device, and complicated work and financial consumption are caused for construction.

Disclosure of Invention

The utility model aims at providing a sound pick-up device to solve the problem that prior art exists. The problem to be solved by the invention is to provide a sound pick-up device, which adopts standard butt joints (such as a network cable crystal head, which is not limited to the connecting device, but is only described and used by the general device) to define contact points (positive and negative poles of a power supply and positive and negative poles of a signal) in each joint; each sound pick-up is provided with two short wires, and the ports of the short wires are embedded into a standard universal butt joint interface.

The technical scheme of the utility model is that: a sound pick-up device comprises a sound pick-up and an outgoing line thereof, wherein the outgoing line is composed of 3-4 core wire harnesses, and is characterized in that the number of the outgoing lines is two, core wires at one end of each outgoing line are respectively and correspondingly connected with the leads of the sound pick-up, and core wires at the other end of each outgoing line are respectively and correspondingly connected with wiring ends of a butt joint. The corresponding relation between the contact points in the butt joint interface and the contact points of the sound pickup is set according to the specific requirements of customers, so that the later wiring harness can be used for butt joint.

And a serial line is arranged between two butt joint interfaces connected with each sound pick-up.

The utility model has the advantages that: in normal use, the power supply and the signal transmission of the whole equipment can be completed by using the universal multi-strand wire harness. The general terminal equipment has a power supply and signal acquisition port, and can provide power supply and transmit signals by only connecting a wire harness. Simultaneously, every pickup apparatus contains two ports, when many pickups use, can adopt general strand to establish ties, alright supply power and signal acquisition to many pickups, realize that a pickups supplies power, and the pickups in the whole link all can obtain the application of power supply work.

Detailed Description

Referring to fig. 1-3, the utility model relates to a sound pickup device, including sound pickup 1, lead-out wire 2, butt joint interface 3, can carry out the contact point according to the concrete demand of customer in the butt joint interface 3 and define (for example positive negative pole of power, signal positive negative pole, see in detail fig. 3) for the butt joint of later stage pencil is used. Each sound pick-up 1 is connected with more than two outgoing lines 2, and each outgoing line 2 can be connected with a butt joint interface 3. When the microphone is used, a plurality of strands of wiring harnesses (such as network cables) can be adopted to connect the outgoing line 2 and the butt joint interface 3, and then the link connection of a single microphone can be completed. The sound pick-up with the device design can be used independently, and can also adopt the serial connection mode shown in figure 2, a plurality of sound pick-up 1 are connected by the serial connection wire 4, thereby saving the long-distance connection wires for power supply and signal output of each sound pick-up, and saving the sound mixing equipment of the terminal.

As shown in fig. 3, the three-wire system connection method is adopted, in which one ends of three wire harnesses of the lead-out wire 2 are connected to the signal positive electrode a, the power supply positive electrode b, and the common end c of the signal negative electrode and the power supply negative electrode of the sound pickup 1, respectively, and the other ends of the lead-out wire 2 are connected to three plugs in the docking interface 3 in a corresponding manner (the corresponding relationship between each plug and each end of the sound pickup 1 is determined). If the four-wire system is adopted, the outgoing line 2 adopts four wire harnesses, and the signal positive pole and the signal negative pole of the sound pick-up 1, and the power supply positive pole and the power supply negative pole are respectively and independently led out and connected with the interface 3 (not shown).
