It is existing.
For example, often occur that people line is more the situation of congestion occurs in city, such as checked out in supermarket shopping
Queuing, the queuing of airport personnel safety check, visitor enter the queuing in garden etc..In such a scenario, general staff can have special messenger's progress
Dredge, the current of different queue is arranged one by one, so as to the appearance for avoiding the occurrence of confusion or trampling.
It is general when there is such case all to be propagandaed directed to communicate from dredging the hand-held loudspeaker of personnel to different queues in reality, it is desirable to
The personnel of a certain queue take action according to instruction.But due to conventional horn be typically it is open amplify, after action order is barked out
It can be heard by other personnel at scene, so as to allow other personnel to be mistakenly considered the instruction assigned to it, cause more queues same
When there is the situation taken action, and then there is the chaotic situation of action.
Therefore, the utility model needs to solve the problems, such as be how to provide a kind of new device can accurately guide correlation
Personnel take action, while avoid the occurrence of other personnel's mistakes and hear that instruction carries out the situation of maloperation.
Utility model content

Preferably, switch is installed, the switch connects the battery module, controls the orientation loudspeaker on the handle
Opening and closing.
The utility model has advantages below：It is defeated that the orientation loudspeaker that the application provides can carry out audio towards assigned direction
Go out, so as to accurately export sound to specified target, while avoid other personnel's misconnections from instructing, it is achieved thereby that to personnel's
Accurate guiding.
Brief description of the drawings
Fig. 1 is a kind of structure chart for orienting loudspeaker first embodiment provided by the utility model.
Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail, and makes above and other purpose of the present utility model, feature and advantage will
Become apparent from.The identical reference instruction identical part in whole accompanying drawings.Not deliberately accompanying drawing drawn to scale, emphasis
It is purport of the present utility model is shown.
Referring to Fig. 1, the figure is a kind of structure chart for orienting loudspeaker first embodiment provided by the utility model.
In the present embodiment, including：Housing 10, handle 20, directional sound cover 30, power amplifier module 101, ultrasonic wave audio emission
Device 102, sound pick-up 103 and generating laser 104；
Preferably, the housing is tubular construction.Opening is left in one end of the housing, and the opening is provided with orientation
Sound cover, housing and directional sound cover can be fixed using snap fit.The other end of housing leaves small breach, and sound pick-up is direct
Gap position is connected to, such sound pick-up can directly receive the sound that external user is sent.Pacify in the side wall of the housing
Equipped with handle.
The power amplifier module and the ultrasonic wave audio emitter are arranged in the housing, the ultrasonic wave audio emission
The surface of emission of device is outside along directional sound cover direction.Preferably, ultrasonic wave audio emitter is connected to the opening, work(
Amplification module is connected and fixed to the bottom of ultrasonic wave audio emitter with ultrasonic wave audio emitter.The sound pick-up passes through circuit
The power amplifier module is connected to, the power amplifier module is connected to the ultrasonic wave audio emitter.User is received in sound pick-up
After the sound sent, electric signal is converted the audio into by sound pick-up, and power amplification is carried out by power amplifier module, finally by super
Sound wave audio emitter carries out audio output.Here ultrasonic wave audio emitter is ultrasonic wave audio emitter, and ultrasonic wave
Audio emitter can also be ultrasonic wave audio emitter array, can so ensure the intensity of ultrasonic wave audio sent.
In addition, being also equipped with handle in the side wall of housing, orientation loudspeaker are gripped for user.Meanwhile in institute
State and be also equipped with switching on handle, the switch connects the battery module, controls the opening and closing of the orientation loudspeaker.
Because ultrasonic wave audio has the characteristics of directionality, if direction, not to if, related personnel can not receive audio, therefore
Generating laser is also equipped with the utility model.The generating laser is arranged on the hair of the ultrasonic wave audio emitter
Penetrate the middle part in face.Voice directions transmitting visible rays of the generating laser along the ultrasonic wave audio emitter.So may be used
To be oriented to the direction of the launch for being accurately positioned ultrasonic wave audio by the light of generating laser.
