Specific embodiment
The present invention will be further described in detail in the following with reference to the drawings and specific embodiments.
It is as shown in Figure 1 a kind of systematic schematic diagram of automotive entertainment system of the present invention, comprising: Vehicle Controller, Yi Jiduo
The sound wave directional loudspeaker 5,6,7,8 that a loudspeaking region does not overlap, the loudspeaking region of the sound wave directional loudspeaker 5,6,7,8
For interior seat 9,10,11,12, the controller is communicated to connect with the sound wave directional loudspeaker 5,6,7,8 respectively, described
Controller controls the operation of the sound wave directional loudspeaker 5,6,7,8.
Specifically, controller can be vehicle-mounted electronic control unit (Electronic Control Unit, ECU), lead to
Controller is crossed to control sound wave directional loudspeaker.It is that 360 degree of spherical shapes are radiate compared to conventional loudspeakers 21, such as schemes
Shown in 2, the maximum bright spot of sound wave directional loudspeaker 22 is exactly that the whereabouts of sound can be specified in open environment, only sound
The user of wave directional loudspeaker alignment can just hear clearly sound.Its working method is similar to flashlight, passes through ultrasound
Sound is focused in short distance by wave technology as light, even if orienting loudspeaking using more sound waves in the same space
Device plays different music, as long as the direction of alignment is not overlapped, music would not be bothered mutually, the user being only aligned
It can just hear.
Sound wave directional loudspeaker preferably uses ultrasonic wave to realize.The loudspeaker of this ultrasonic wave generally only has half inch thick,
Driven by amplifier, amplifier sends voltage on the metallized polymer film of acoustical generator, allow film with 60,000 hertz or
The higher frequency vibration of person, generates ultrasonic wave.In air, the density of uniform ultrasonic wave generates fluctuation, and ultrasonic wave is sent out immediately
It is raw to change, it is transformed into the sound that human ear can be heard.
Fig. 1 is the arrangement schematic diagram in automotive entertainment system of the present invention space 100 in the car.It can be seen that since sound wave orients loudspeaking
The loudspeaking region of device 5,6,7,8 does not overlap, and therefore, the audio that each sound wave directional loudspeaker 5,6,7,8 is broadcasted only can quilt
Passenger in its loudspeaking region hears, without will affect other passengers.
The present invention passes through controller control by the way that the sound wave directional loudspeaker that multiple loudspeaking regions do not overlap is arranged in the car
Different sound wave directional loudspeakers is made, so that sound is not interfere with each other, completely self-contained information joy is may be implemented in passenger inside the vehicle
