Reverse Horn Voice - Prompting IC - KT148A Broadcasting Chip, Building a Solid Safety Line

When vehicles and mechanical equipment are reversing, the driver's line of sight is often blocked by the vehicle body, cargo, or environmental factors, creating a large blind spot. For large - scale equipment such as forklifts, excavators, and heavy - duty trucks, due to their large size and limited visibility, the accident risk is even higher. Moreover, traditional reverse alarm sounds are mostly monotonous beeps, which have low recognition in noisy industrial environments or traffic roads and are difficult to attract the sufficient attention of people around.

To address this safety pain point, reverse horns are evolving from simple buzzers to intelligent devices with voice - prompting functions. Voice prompts can convey reversing information clearly and explicitly in words. Compared with a single beep, they can more effectively attract the attention of people around, enhance the warning effect, and reduce the probability of reversing accidents.

Demand Design for Reverse Horn Voice Solutions：

• Without the warning of a reverse horn, people around may not be able to detect the vehicle's reversing in time. When the line of sight is blocked or attention is distracted, accidents such as vehicles colliding with pedestrians or running over objects are likely to occur.

• Without a reverse horn, the driver can only use methods such as waving hands or shouting to remind people around to give way. However, these methods are limited by factors such as environmental noise and distance, and cannot ensure the effective transmission of information. This leads to low reversing operation efficiency and may also cause misunderstandings and conflicts due to poor communication.

• In case of a reversing accident, if there is no effective warning device such as a reverse horn, it is difficult to prove whether the driver has fulfilled the necessary safety - prompting obligation during the accident liability determination, increasing the complexity of liability division and the risk of disputes.

KT148A Voice Chip Solution for Reverse Horn：
Adding the KT148A voice - broadcasting chip to the reverse horn can achieve functions such as "reverse reminder, left - turn reminder, right - turn reminder". When reversing, through this alarm chip, passers - by can know the vehicle's driving direction in time, playing a reminder role. It not only makes the driver actively aware of safety but also reminds passers - by to pay attention to passing pedestrians and vehicles.

The KT148A voice chip, with its numerous outstanding features, is often selected by manufacturers of alarm - type products. It is an industrial - grade voice chip suitable for mass production by voice horn manufacturers and an excellent option for the voice chip of reverse horns.

• Ultra - simple Peripheral Circuit：The peripheral circuit is ultra - simple. It interfaces with the main control system of the reverse horn conveniently and efficiently, greatly reducing the product research and development cost and development cycle. Enterprises can quickly complete the chip's program burning and function debugging according to their own needs, realizing the intelligent upgrade of the reverse horn.

• Ultra - low Cost：It has an ultra - low cost, providing strong support for enterprises to reduce production costs.

• Powerful Voice Functionality：It has a built - in 420K Byte voice storage space, supports 224 segment addresses and can be expanded to meet more needs. It supports up to 200 seconds of voice playback at 16KHz and up to 400 seconds at 8KHz. Tools are provided for users to convert audio formats themselves, which is very simple for all users. Users can also replace the voice content directly via the serial port on a computer without the need for other expensive tools.

• High - fidelity Voice Output：As a 32 - bit DSP voice chip, it uses 16 - bit PWM output and can directly drive an 8 - ohm / 0.5W speaker to achieve clear, loud, and distortion - free voice playback. It has an 8 - level volume adjustment function, allowing for flexible adjustment of the voice playback volume according to different scenarios to achieve the best warning effect.

• Stable and Reliable Operating Performance：The chip adopts a highly integrated design, with a 5MHz internal oscillator and PLL up to 120MHz. It has excellent anti - interference capabilities, an operating voltage range of 2.0 - 5.5V (note that there are detailed hardware differences when supplying below 3.3V), and can work stably in complex environments such as high - temperature, humid, and electromagnetic - interference conditions.

• Flexible Development and Control：It supports one - wire serial port control and can customize various protocols according to needs. It has hardware IIC and UART interfaces, enabling customization of various functions for customers. The chip also has the ability to be reprogrammed, eliminating concerns about batch issues caused by incomplete testing.
