Abstract

The utility model relates to a paraboloid focusing acoustic wave signal pick-up which belongs to the technical field of the structures of pick-ups. The parabolic focusing acoustic wave signal pick-up is provided with a paraboloid reflecting and focusing hood (2), and a bracket (3) is arranged on the inner side of the paraboloid reflecting and focusing hood. A microphone (1) is arranged on the bracket (3). A receiver (4) of the microphone, which faces the paraboloid reflecting and focusing hood (2) is positioned at the focused point which is reflected by a paraboloid. In the utility model, the microphone integrally combined with the technology of a paraboloid satellite signal receiving antenna. The utility model has the advantages of simple structure and good sound taking effect, and is convenient for people to use for conferences, shoot, interviews, live recording, etc. on various occasions.

Description

Parabolic focused sound waves signal pick-up

Technical field

The utility model belongs to the pick-up technical field of structures.

Background technology

Traditional pick-up does not have the ability of focused sound waves signal, can only the acoustic signals on the receiver blaze abroad in the pick-up with being directly delivered to, thereby it is relatively poor to adopt the audio fruit, using also has inconvenience.For example, in a lot of occasions, pick-up be aimed at and sound effectively could be spread out of near mouth, the pick-up part has been blocked people's face usually; Taking occasions such as documentary film or documentary film, also take into for fear of the personnel that will interview, often pick-up to be tied up the overhead that on long pole, reaches reference object and remove to adopt sound, very painstaking; For scenes such as wide-long shot such as explosion, blast, operation, sports, if a plurality of pick-ups are not set in forward position, then be difficult to gather the sound of scene on the spot, and also pick-up can't forwardly in these cases be set usually.

Summary of the invention

The purpose of this utility model provides in order to overcome above-mentioned the deficiencies in the prior art just a kind ofly can effectively gather the acoustic signals of longer-distance target and it is focused on the receiver, easily truly to obtain the parabolic focused sound waves signal pick-up of sound effect on the spot.

The purpose of this utility model is achieved by the following technical solution.

This parabolic focused sound waves signal pick-up is provided with a parabolic reflective focusing cover, and parabolic reflective focusing cover inboard is provided with support, and microphone is arranged on the support, and the receiver of microphone is towards the parabolic reflective focusing cover and be positioned at the focus point of parabolic reflector.

Be arranged at the support of the support of parabolic focus mask inboard at least three legs, microphone is installed on the leg crosspoint; The parabolic reflective focusing cover is umbrella-shaped structure cover fixing or can be folded.

The utility model is accepted antenna technology with microphone and paraboloid satellite signal and is combined as a whole, utilize the parabolic reflective focusing cover acoustic signals is collected and reflect focalization on the receiver of microphone, its advantage one is that the pickup distance is big, as long as do not have interruption between pick-up and the source of sound, just can effectively adopt sound; The 2nd, directionality is strong, can effectively get rid of the sound interference of other direction.The parabolic reflective focusing cover adopts the umbrella-shaped structure of collapsible folding and unfolding, can be convenient to the carrying of larger-size pick-up.

Further set forth the utility model below in conjunction with Figure of description.

Description of drawings

Fig. 1 is a front view of the present utility model,

Fig. 2 is a left view of the present utility model,

Fig. 3 is that acoustic reflection of the present utility model is assembled schematic diagram,

Fig. 4 is that the utility model is installed on the schematic diagram in the triangle body seat board.

Embodiment

At first, as shown in Figure 1 and Figure 2 with reflecting effect preferably material such as aluminium alloy make parabolic reflective focusing cover 2, and, adopt the microphone 1 of prior art and it be arranged at the crosspoint 5 of support at focus mask installed inside three-legged support 3.With receiver 4 one end faces of microphone 1 towards the parabolic reflective focusing cover and be located at paraboloidal focus place.As shown in Figure 3, sound wave 6 propagates on the receiver 4 that focuses on microphone 1 that is reflected behind the parabolic reflective focusing cover 2, and receiver can collect the sound wave that is focused preferably, thereby obtains the stronger audio fruit of adopting.

The utility model can be made into hand-held interview, pick-up for shooting, also can make the pick-up that is hidden in some implements.As shown in Figure 4, the utility model is made into the smaller volume size to be placed in the triangle body seat board that often is placed in the meeting on the conference table, triangle body is offered an opening 7 towards talker's one side, be the utility model in the opening, its parabolic reflector is towards the talker, and triangle body still can stick talker's name towards spectators' one side.The utility model can also be hidden and be installed in some ornaments such as the fresh flower.When needs are adopted sound at a distance, parabolic reflective focusing cover of the present utility model can be made into big specification and with the pick-up overall fixed on can the bearing of universal rotation, so that manipulate.

The utility model is simple in structure, and it is effective to adopt sound, has solved the deficiency of existing pick-up, is convenient to meeting, shooting, interview and live recording etc. that people are used for various occasions.
