Description
Technical field
The present invention program relates to a kind of manufacture field of sound transmission device.
Background technology
In the prior art, sound transmission device generally has microphone and transmission line to form, microphone is in order to collect sound and to convert thereof into electric signal, and transmission line is in order to transmit this electric signal, but these technology have a common shortcoming, in the time of the uncomfortable generation cough of announcer phenomenon, easily bring two problems, one: synchronous s cough typing program, affect program quality, two: cause announcer's self anxiety, particularly evident when the impact of these two problems is live at the scene.
Summary of the invention
The technical matters that the present invention program will solve is the present situation for prior art, provides a kind of simple and reasonable, manufacture easy for installation, a kind of sound transmission device that can automatic shield s cough.
The technical scheme that the present invention program addresses the above problem is: a kind of sound transmission device, comprise a Basic Transmission Unit, this Basic Transmission Unit is made up of microphone and transmission line, microphone is in order to collect sound and to convert thereof into electric signal, transmission line is in order to transmission of electric signals, also comprise a recognition unit, a control module; Whether recognition unit covers mouth state in order to identification, covers mouth state and refers to the state of covering the bar of shutting up with hand; Control module is according to the recognition result control Basic Transmission Unit of recognition unit, be specially when recognition unit unidentified when covering mouth state, control module control Basic Transmission Unit is in running order, when recognition unit recognizes while covering mouth state, control module control Basic Transmission Unit interruption of work state.Basic Transmission Unit is in running order under normal conditions for a kind of sound transmission device of the present invention program, be that microphone and transmission line are all in running order, the process that now broadcasts is by synchronous transmission, as once announcer is about to cough, announcer can subconsciously remove to cover with hand the bar of shutting up, recognition unit recognizes this state and informs control module, control module control Basic Transmission Unit interruption of work state, thereafter the s cough occurring is not by synchronous transmission, s cough is effectively shielded, until cough finishes, announcer's hand leaves face, recognition unit is unidentified to covering mouth state, control module control Basic Transmission Unit resumption of service, continue normal work.
Whether recognition unit covers mouth state in order to identification, particularly important concerning the present invention program.
Preferably, recognition unit comprises a sticking tablet, the sticking tablet back side has glued construction with so that sticking tablet is bonded in chin place, and sticking tablet front is provided with right conducting strip, and right conducting strip is connection the first power supply successively, the first resistance, left conducting strip, left conducting strip is arranged on hand, when hand is covered when bar of shutting up, right conducting strip and left conducting strip are in contact with one another, and a line connection control unit is respectively drawn in order to control module input voltage signal in the first resistance two ends.In the time covering mouth state, right conducting strip and left conducting strip are in contact with one another, whole circuit is switched on, the first resistance two ends produce voltage, this voltage signal is transfused to control module, otherwise in the time covering mouth state, whole circuit disconnects, the first resistance two ends no-voltage is poor, and the voltage signal that control module is received is zero.
In such scheme, announcer's face has been worn sticking tablet, very not attractive in appearance, so this scheme is only applicable to radio programmes, for being applicable to TV programme, is necessary to be improved.
Preferably, recognition unit comprises a circuit fracture, conductive paper, circuit fracture is in series with second source between two ends, the second resistance, and circuit fracture is arranged on hand, conductive paper is bonded in lip place, cover when hand when bar of shutting up, conductive paper is connected circuit fracture two ends just, and a line connection control unit is respectively drawn in order to control module input voltage signal in the second resistance two ends.When hand is covered when bar of shutting up, conductive paper is connected circuit fracture two ends, whole circuit is switched on, the second resistance two ends produce voltage, this voltage signal is transfused to control module, otherwise in the time that hand leaves face, whole circuit disconnects, the second resistance two ends no-voltage is poor, and the voltage signal that control module is received is zero.For more attractive in appearance, the color of conductive paper is pink, is consistent with lip.
Obviously, recognition unit also has more technical scheme, and all features of covering face action and cause that are accompanied by all can be used for reference the technical program.
Control module is according to the recognition result control Basic Transmission Unit of recognition unit, particularly important concerning scheme of the invention.
Preferably, control module comprises one first single-chip microcomputer, the first switch; The first switch is arranged on transmission line in order to control transmission line break-make, the first single-chip microcomputer input end linkage identification unit, and the first single-chip microcomputer output terminal is by one first executive circuit control the first switch.The first single-chip microcomputer input end linkage identification unit makes the first monolithic function obtain the recognition result of recognition unit, the first single-chip microcomputer output terminal is by one first executive circuit control the first switch, and the first monolithic function is by the state of the first switch control transmission line in on-off.When transmission line is connected, Basic Transmission Unit is in running order, and transmission line connects Basic Transmission Unit interruption of work state while disconnection.
