How to distinguish between high-frequency and low-frequency car horns?

The unit responsible for reproducing high-frequency sounds, due to the higher frequencies, has a relatively thinner diaphragm to adapt to high-frequency vibrations. Responsible for reproducing low-frequency sounds, with larger and relatively slower vibration amplitudes, hence equipped with thicker paper cones and voice coils. The characteristic of high-frequency horns is the ability to vibrate quickly to produce sound, but their vibration amplitude is usually smaller. Their feature is having sufficiently large vibration amplitudes to push air and create high sound pressure (also known as sound pressure waves).

What to Do If Failing the Vision Test for Driver's License Physical Examination?

Applying for large passenger vehicles, tractors, city buses, or tram driving license categories. For other driving license categories, the naked or corrected vision of both eyes must reach above 4.9 on the logarithmic visual acuity chart. For monocular vision impairment, the vision must reach above 5.0 on the visual acuity chart, and the horizontal field of vision must reach 150 degrees. As long as you can pass the vision test.

Is the CHR from GAC or FAW?

C-HR is the name used by GAC, while FAW calls it the IZOA; they are the same vehicle. Below is relevant information about the Toyota C-HR: Exterior: The Toyota C-HR made its debut at the 2016 Geneva Motor Show, positioned as a compact SUV. The overseas version features Toyota's latest 'X'-shaped front grille design. The new car adopts taillights resembling the Civic Coupe's boomerang style, with black mirror caps/body panels/spoilers and a floating C-pillar, giving it a crossover sporty appeal. Interior: The overseas version is equipped with an 8-inch multimedia touchscreen, and the extremely minimalist center console button layout ensures a clean visual effect. Additionally, the new car comes with an upgraded Toyota HMI human-machine interaction system as the onboard multimedia information system. Powertrain: The overseas 1.2T model delivers a maximum output of 85kW with a peak torque of 200N·m, paired with a simulated 7-speed CVT automatic transmission. The hybrid version is powered by a 1.8L Atkinson-cycle four-cylinder engine + two electric motors, with an output of up to 90kW and thermal efficiency exceeding 40%. The hybrid version has a fuel consumption of 3.3L/100km, while the 1.2T model consumes 6.4L/100km.

How to Remove the Steering Wheel of a Kia K2?

For safety reasons, disconnect the battery cables before removal. It's best to have two people working together. Use a hex wrench to remove the two screws under the steering wheel. After removal, pull out the airbag. Then, after loosening the screws, gently wiggle and use a puller to slowly extract it. Once removed, also take off the two reserved plastic shells. Another method is forceful removal: loosen the height and front-back adjustment of the steering wheel, slightly lift the steering wheel upwards, and then hammer the central shaft.

How to Distinguish Positive and Negative Terminals of Car Horn Wires?

Select the range and setting of the polarity tester based on the horn's power and voltage. Connect the test leads, power up the polarity tester, and turn on the polarity tester switch. Touch the test leads to the two input terminals of the horn (speaker). The horn will emit intermittent beeping sounds. Align the horn towards the microphone of the polarity tester. The indicator lights will illuminate: green indicates positive, and red indicates negative. If the result is positive, the terminal touched by the positive test lead is the positive terminal, and vice versa for the negative terminal. If a single horn is used for listening to music, the polarity of the horn has no effect.

How to Turn On Active Noise Cancellation in the Tenth-Generation Accord?

The button for active noise cancellation in the tenth-generation Accord is located above the driver's head, where you'll find a small circle indicating the active noise cancellation button. Additionally, active noise cancellation can be turned off at any time. Active noise cancellation works by generating reverse sound waves equal to external noise through the noise-canceling system, thereby neutralizing the noise and achieving the noise reduction effect. All sounds are composed of certain frequency spectra. If a sound can be found with a spectrum identical to the noise to be eliminated but in opposite phase, the noise can be canceled out.
