Abstract
The utility model discloses a kind of campus broadcasting orientation stereomicrophone systems, including campus network, campus network be connected with the network paging microphone of headmaster's office, the network paging microphone of entrance guard room, central control room network adopt the central host for broadcasting host, the network paging microphone of central control room, central control room, the network of central control room, which is adopted, to be broadcast host and is connected with CD player and tape deck.It has the advantage that using transaudient sound equipment is oriented, only can hear broadcast in the transaudient 30 ° of angular regions of sound equipment of orientation, reduce influence of the campus broadcasting sound equipment to the noise of school's nearby residents.
Description
Technical field
The utility model relates to a kind of campus broadcasting orientation stereomicrophone systems, belong to ultrasonic directional sound technique field.
Background technique
Broadcast is known very early as a kind of information spreading medium, and is widely applied in daily life.School
The important tool propagated as school information is broadcasted in garden, is just developed towards " digitlization, networking, intelligence " direction, realization and
Therefore the combination of cable television and computer network builds an automation, intelligentized Campus Public Address Systerm just seems ten
Divide necessity.
At present in national urban planning, about the regulation of Layout of Primary & Middle Schools, school is to merge each other with residential block itself
Composition, the phenomenon that this results in campus broadcasting noise disturbs residents frequent occurrence, influence the quality of life of nearby residents, cause resident
Contradiction between school.
Utility model content
Problem to be solved in the utility model is against the above deficiency, to provide a kind of campus broadcasting orientation stereomicrophone system,
Using transaudient sound equipment is oriented, broadcast only can be heard in the transaudient 30 ° of angular regions of sound equipment of orientation, reduce campus broadcasting sound equipment to school's week
The influence of the noise of side resident.
To solve the above-mentioned problems, the utility model uses following technical scheme:
A kind of campus broadcasting use orientation stereomicrophone system, including campus network, the network that campus network is connected with headmaster's office are sought
The network of microphone, the network paging microphone of entrance guard room, central control room is exhaled to adopt the network paging microphone for broadcasting host, central control room
With the central host of central control room, the network of central control room, which is adopted, to be broadcast host and is connected with CD player and tape deck.
Further, the campus network is also connected with the orientation sound equipment power amplifier outside the orientation sound equipment power amplifier and classroom on playground,
The orientation sound equipment power amplifier on playground is connected with the ultrasonic directional Waterproof sound on playground, and the orientation sound equipment power amplifier outside classroom is connected with religion
Outdoor ultrasonic directional Waterproof sound.
Further, the campus network be also connected with playground network it is preposition, the network on playground is preposition to be connected with playground
Pure rear class power amplifier, the pure rear class power amplifier on playground are connected with the waterproof sound column on several playgrounds.
Further, the campus network is also connected with IP network sound column, several indoor IP network sounds outside several classrooms
Case, indoor IP seek help terminal and indoor orientation sound equipment power amplifier, and indoor orientation sound equipment power amplifier is connected with indoor ultrasonic wave
Orient Waterproof sound.
The utility model is had the following technical effect that compared with prior art using above technical scheme
Using transaudient sound equipment is oriented, broadcast only can be heard in the transaudient 30 ° of angular regions of sound equipment of orientation, reduces campus broadcasting sound equipment
Influence to the noise of school's nearby residents.
Technical solutions of the utility model are described further with reference to the accompanying drawings and examples.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of campus broadcasting orientation stereomicrophone system in the utility model embodiment.
Specific embodiment
Embodiment 1, as shown in Figure 1, a kind of campus broadcasting is connected with orientation stereomicrophone system, including campus network, campus network
The network paging microphone of headmaster's office, the network paging microphone of entrance guard room, central control room network adopt broadcast host, center control
The network paging microphone of room processed and the central host of central control room, the network of central control room adopt broadcast host be connected with CD player and
Tape deck.
The campus network is also connected with the orientation sound equipment power amplifier outside the orientation sound equipment power amplifier and classroom on playground, the orientation on playground
Sound equipment power amplifier is connected with the ultrasonic directional Waterproof sound on playground, and the orientation sound equipment power amplifier outside classroom is connected with the ultrasound outside classroom
Wave orients Waterproof sound.
The network that the campus network is also connected with playground is preposition, the preposition pure rear class function for being connected with playground of the network on playground
It puts, the pure rear class power amplifier on playground is connected with the waterproof sound column on several playgrounds.
The campus network is also connected with IP network sound column outside several classrooms, several indoor IP network speakers, indoor
IP seeks help terminal and indoor orientation sound equipment power amplifier, and indoor orientation sound equipment power amplifier is connected with the anti-hygrechema of indoor ultrasonic directional
It rings.
The ultrasonic signal multiplying power amplification that the orientation sound equipment power amplifier is used to convert digital signals into.
The ultrasonic directional Waterproof sound launches ultrasonic signal, and the direct sound for generating certain angle is concurrent
It send to specified region.
The network paging of the network paging microphone of headmaster's office, the network paging microphone of entrance guard room and central control room is talked about
Cylinder sound is transferred on playground, outdoor, indoor sound column and ultrasonic directional Waterproof sound by campus network, and sound passes through sound column
It is broadcasted with ultrasonic directional Waterproof sound.
Common acoustic signal can be converted to direction by campus broadcasting described in the utility model with orientation stereomicrophone system
Property voice signal transmit transmitting, launch angle be 30 °, can keep hearing sound in a certain range angle, not interfere other areas
The people in domain.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field
The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality
The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
