Abstract
The utility model discloses a camera integrated with a loudspeaker. The loudspeaker and a visible image electric signal conversion circuit of the camera are arranged in the same shell. In places for shooting images and playing sounds, particularly in places for video monitoring and sound warning, the external loudspeaker is not needed any more, so that the problems that the installation cost of the loudspeaker is increased, the installation workload is increased and the appearance is influenced are solved.
Description
Technical field
The utility model relates to a kind of loud speaker one camera.
Background technology
Camera is widely used in field of video monitoring at present, though title is described but complete product with a word.Camera on the market is made up of video electrical signal conversion circuit, optical lens, support or shell and signal wire interface, and the minority camera integrates devices such as microphone or infrared induction, but does not integrate the camera of loud speaker.At present,, particularly need the place of sound caution simultaneously at video monitoring in some places that should make a video recording and play sound again, have to external installation loud speaker.The bad part of external installation loud speaker is to increase cost and increase installation workload, even influences attractive in appearance.Use loud speaker one camera to address these problems.
Goal of the invention
The utility model discloses a kind of technical scheme of loud speaker one camera.
The utility model content
For the camera that does not have shell, need add casing to camera.The video electrical signal conversion circuit of loud speaker and camera is installed in the same shell.For making the smooth and easy outside propagation of sound, near speaker openings place open pore, for water-proof CCD camera, pore is opened in the shell below on shell.
Power of loudspeaker is relevant with application places, is used for the video monitoring place, and audio power has 1W enough, so, selects for use 1 to 5W loud speaker to get final product.
Because the audio transmission of many application scenarios is bigger apart from difference; Use for adapting to more occasions; Can consider built-in audio frequency amplifier, behind the built-in audio frequency amplifier, audio frequency can adopt the transmission of high impedance transmission means; Adopt high impedance transmission means transmission of audio, the occasion that can adapt to various different transmission ranges is used.
To be applied to the networking field fashionable when this loud speaker one camera, also must consider audio frequency gating problem.This product of audio exchange machine is arranged on the market, can be used as the audio frequency gating.Also can be in camera built-in audio gate; Built-in audio gate recommends to use the FSK decoding circuit; Because fsk signal can transmit on tone frequency channel wire; Like this, gating signal can with the shared transmission line of audio signal, when reality is used, no longer need to lay in addition the gating signal transmission cable.
For the ease of installing, loud speaker one camera refills and establishes audio input interface on the basis of video output interface and power input interface, and loud speaker is by audio input interface incoming audio signal and sounding.

Embodiment
Introduce the way of above technical scheme in detail below in conjunction with Figure of description.As shown in Figure 1, loud speaker one camera is by optical lens 1, video electrical signal conversion circuit 2, and shell 3, loud speaker 4, audio input interface 6, power input interface 7, video output interface 8 constitutes.Loud speaker 4 is fixed within the same shell 3 with video electrical signal conversion circuit 2, and near loud speaker 4 opening part open pores 5, for water-proof CCD camera, pore 5 is opened in shell 3 belows on shell 3.Loud speaker one camera refills and establishes audio input interface 6 on the basis of video output interface 8 and power input interface 7, and loud speaker 4 is by audio input interface 6 incoming audio signals and sounding.Video electrical signal conversion circuit 2 is outwards carried vision signal through video output interface 8, and power input interface 7 provides whole camera power supply.
Claims (1)
1. loud speaker one camera; It is characterized in that: loud speaker (4) is installed in the same shell (3) with the video electrical signal conversion circuit (2) of camera; Go up near loud speaker (4) opening part open pore (5) at shell (3); Installing audio input interface (6), loud speaker (4) is by audio input interface (6) incoming audio signal and sounding.
