The “Voice Brain” for Home Appliances and Toys: The KT148A Series of Programmable Voice Chips Are Here!

In the era when electronic products are increasingly pursuing intelligence and human - orientation, voice interaction has become a key factor in enhancing the user experience.

The KT148A series of programmable voice chips launched by Qingyue Electronics, with its excellent performance and wide applicability, is bringing a new revolution to the home appliance and toy industries, making it an ideal choice for many manufacturers.

The KT148A Series Chips Make Home Appliances Understand Users Better

1. Stability in Complex Environments

Home appliances often face challenges such as voltage fluctuations, sudden changes in temperature and humidity. The KT148A series chips have a wide voltage range of 2.0V - 5.5V, enabling them to operate stably in extreme environments such as the high - temperature and high - humidity kitchen and the low - temperature freezer of the refrigerator, perfectly solving the problem of poor anti - interference of ordinary chips.

2. Space - saving and Cost - effective Design

The internal space of home appliances is precious. The KT148A series chips can work with only 1 power - coupling capacitor, eliminating the need for complex peripheral circuits. With a large internal storage space of 420KByte, it can store up to 420s of voice, saving additional components, simplifying wiring, and reducing material costs.

3. Flexible Control to Suit All Kinds of Home Appliances

  • Basic Home Appliances (such as electric kettles, fans): The button - control mode can be used to achieve voice prompts such as "Water boiled reminder" and "Wind speed adjustment".
  • Smart Home Appliances (such as refrigerators, washing machines): Through a one - line serial port connection with the MCU, it can achieve complex interactions such as food expiration warnings and washing progress announcements.

The KT148A Series Voice Chips Enhance the Competitiveness of Toy Products

1. High Cost - performance and Flexible Voice Update

  • Low - cost and Reprogrammable: Different from traditional OTP chips, the KT148A supports multiple burn - in. No additional expensive tools are required. Users can directly update the voice content through the computer serial port, greatly reducing development and production costs.
  • Customizable Voice Content: Toy manufacturers can quickly change the voice content according to market demands without replacing the chip. It supports flexible switching of multiple languages and versions, improving product adaptability and market response speed.

2. Excellent Sound Quality and Driving Ability

  • 420 - second Built - in Voice Space with High - quality Sound: It supports a maximum sampling rate of 16KHz, providing clear and natural sound quality, which is suitable for scenarios with certain sound - quality requirements such as children's toys and educational products.
  • Directly Drive a 0.5W Speaker: With built - in PWM output, it can directly drive an 8Ω/0.5W speaker without an external power amplifier, simplifying the circuit design and reducing costs.

3. Rich Control Functions and Low - power Design

  • One - line Serial Port Control, Support for Combined and Loop Playback: Through simple commands, functions such as combined playback of multiple voice segments, loop playback, and volume adjustment can be achieved, enhancing the interactivity and playability of toys.
  • Ultra - low Power Design for Longer Battery Life: The standby power consumption is less than 25μA, and the ultra - low power mode can reach 1.7μA. It is especially suitable for battery - powered toy products, extending the usage time.

The KT148A series of chips, with its advantages of low cost, high performance, high sound quality, and easy integration, has great application value in products such as smart toys, educational robots, interactive dolls, and children's early - education machines, significantly improving the market competitiveness and user experience of products.

Why choose the KT148A series? ✅ Low cost | ✅ Stable performance | ✅ High sound quality | ✅ Easy integration

KT148A Voice Chip Issue: Difficult to Play with Code Sending - Normal Playback After Grounding Pin 4, What’s the Reason?

图片
Problem Description: Hello, we’ve encountered an issue and would appreciate your support: With the KT148A chip, after powering on, sending the code rarely triggers playback. However, if we use tweezers to briefly short Pin 4 (PB0) to ground and then send the code again, playback works normally. What could be causing this? Based on the observed behavior, it’s highly likely an issue with the timing of one-wire communication,  particularly with the start signal, which may be too short.  Let’s analyze this in detail and review the KT148A schematic as follows: 1. Pin 4 (PB0) of the Chip: PB0 is a test pin with the default factory function of triggering wake-up and playback when grounded. 2. Customer Description: When the customer uses tweezers to short PB0 (Pin 4) to ground, it follows this principle. The shorting action actually performs two operations: Action 1: The KT148A detects a falling edge signal, wakes up, exits low-power mode, and enters full-speed operation. Action 2: Th...

KT1025A Dual-Mode Bluetooth Audio Chip Layout Description and Design Precautions

图片
  1. Brief Overview 1. First, please refer to the provided BT201 test DEMO module as the standard. 2. If using the chip independently without testing the BT201 module and directly proceeding to layout, background noise is highly likely if experience is limited. Therefore, always compare with the manufacturer’s test board first. 3. The BT201 solution does not include FM functionality. Please note this. The FM circuit should be left floating without hesitation 2. Precautions 1. Background noise or interference is common in Bluetooth audio products. Do not be careless during layout. 2. If you have not worked on audio products before, study online resources thoroughly. Assuming things casually will naturally lead to noise issues. 3. The core principle is to separate analog ground and digital ground. If unclear, consult an experienced engineer. 4. Ensure a clean power supply. Use an LDO whenever possible instead of a DC-DC converter. 5. Bluetooth operates at high-frequency RF and radiat...
