Technical field
The utility model relates to the automobile servicing unit, relates in particular to a kind of apparatus for automatically regulating sound volume for automobile audio.
Background technology
In the Vehicle Driving Cycle process, the increase of the speed of a motor vehicle causes that wind noise increases, when especially running at high speed with motor instant raising rotating speed, wind noise increases simultaneously, and vehicle body mechanical shock noise, engine noise also increase thereupon, the occupant can feel that the volume of sound system diminishes, affect the result of broadcast of car audio system, need driver and crew oneself manually to carry out volume adjusting, low when high when the speed of a motor vehicle is understood when complex road condition, need to ceaselessly regulate the volume of sound system, satisfy the auditory effect under the different noise circumstances.
Open day is on November 30th, 2011, publication number is that the patent documentation of CN202059557U discloses the technical scheme that name is called a kind of automobile sound equipment volume dynamic regulator, it comprises shell, be positioned at the resistor rod of shell, be socketed on the resistor rod and reciprocating metal weight, be used for to support resistor rod and be arranged at least one pair of conduction load-bearing pillar on the outer casing inner wall, and guarantee the reciprocating actuating member of metal weight, wherein metal weight reciprocating motion under the active force of pickup and actuating member, make the volume of two different sound channels of sound system increase a mode that subtracts with one and change thereupon, increased auditory effect.Because this technical scheme is connected in series the variable resistor with acceleration change in the loud speaker loop, a channel sound is diminished, it is large that another channel sound becomes relatively, thereby make sound field with the vehicle acceleration and deceleration, about the change of turning round, but exporting total volume noise such as can not make an uproar with the wind changes and changes, therefore, can not satisfy noise and increase auditory effect under the environment.
Summary of the invention
The utility model mainly provides a kind of automobile audio volume adjustment device that comes automatic regulating volume that changes with engine behavior and the speed of a motor vehicle.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of automobile audio apparatus for automatically regulating sound volume, comprise sound system central processing unit, throttle position sensor, volume control potentiometer and audio-frequency power amplifier, the sound system central processing unit is connecting joint valve position sensor, volume control potentiometer and audio-frequency power amplifier respectively, volume control potentiometer also connects audio-frequency power amplifier, volume control potentiometer is to have the potentiometer that motor is regulated resistance, motor connecting sound equipment system central processor.
Throttle position is actual to be accelerator open degree, and control unit of engine is controlled distributive value according to throttle position, and therefore, what throttle position reflected is the aperture of gas pedal.The sound system central processing unit detects throttle position and the amplitude of variation in the unit interval by throttle position sensor, judge the automobile acceleration, deceleration, and control accordingly the output volume of audio-frequency power amplifier, the volume control mode is to increase volume or reduce volume on current volume gain basis.The sound system central processing unit is regulated the volume of sound system automatically according to the situation of change of throttle signal.The sound system central processing unit rotates to regulate the volume control potentiometer resistance by the control motor, and this potentiometer is the potentiometer that translator drives, and is matured product, but gets final product also motorized adjustment of manual adjustments.
As preferably, the sound system central processing unit also connects the vehicle-mounted CAN bus, receives the vehicle speed signal on the CAN bus, compares with the speed of a motor vehicle threshold value of setting, when the vehicle speed value that receives was less than or equal to speed of a motor vehicle threshold value, the sound system output volume was the volume that the manual adjustments potentiometer is set; When the vehicle speed value that receives〉during speed of a motor vehicle threshold value, the sound system output volume is to increase volume on the manual adjustments potentiometer is set the basis of volume again.
As preferably, the sound system central processing unit also connects a speed of a motor vehicle threshold settings key.In the sound system central processing unit, set four speed of a motor vehicle threshold values, be respectively 70Km/H, 80Km/H, 90Km/H and 100Km/H, the driver can use the selection that circulates of speed of a motor vehicle thresholding setting key in advance, travel middle sound system central processing unit with the speed of a motor vehicle threshold value of selection and the real-time speed of a motor vehicle contrast of reception, to determine the sound system volume.
As preferably, the sound system central processing unit also connects a volume gain setting key.Suppose under specified initial conditions, undistorted (distortion does not surpass 1%), omnidistance volume was the 0-100% volume, when carrying out volume gain control, recruitment is divided into three amount of gain: be respectively the variation demand that 4%, 8%, 16% omnidistance volume can satisfy when driving volume, the driver can use the volume gain setting key to the selection that circulates of three amount of gain setting in advance.
As preferably, volume control potentiometer is to have the exponential type potentiometer that motor is regulated resistance.Exponential type potentiometer characteristic show as first slow after fast attenuation characteristic because it has offset non-linear on people's ear sense of hearing, make and feel on the sense of hearing that the volume adjustment is even adjustment, has enlarged adjusting range.
The beneficial effect that the utility model brings is, by in sound system, increasing the volume auto-adjustment control, when driving, needing to avoid the volume of manual adjustments sound system ceaselessly to satisfy auditory effect under the different noise conditions, increased comfortableness and the fail safe of driving.Apparatus structure is simple, detection is accurate, easy to use.
Description of drawings
Fig. 1 is a kind of theory diagram of the present utility model.
Among the figure: the 1st, sound system central processing unit, the 2nd, throttle position sensor, the 3rd, volume control potentiometer, the 4th, audio-frequency power amplifier, the 5th, loud speaker, the 6th, vehicle-mounted CAN bus, the 7th, speed of a motor vehicle threshold settings key, the 8th, volume gain setting key.
