In the acoustic design of electronic devices, the performance of voice chips plays a decisive role in the sound performance of products. From the reverse prompts of cars, the fault alarms of industrial equipment to the interactive sound effects of children's toys, for engineers to select the right voice chip, they must clearly understand the matching logic between core sound - quality parameters and application scenarios. This article will systematically analyze the key parameters of voice chips, and taking KT148A and KT142C voice chips as examples, provide detailed selection guidance based on their specific characteristics. Detailed Explanation of Core Sound - quality Parameters of Voice Chips The sound quality of voice chips is determined by a series of technical parameters, which are directly related to the reduction, clarity, and applicability of sound. 1.Sampling Rate (Hz) The number of times the sound signal is collected per second, which determines the accuracy of restoring...

  Bluetooth technology has been deeply integrated into our lives. Most devices such as smartphones, tablets, and smart home devices are closely related to it, and the Bluetooth chip is the core component of these devices. Today, we are going to discuss the KT1025A dual - mode Bluetooth chip, which integrates classic Bluetooth and low - power Bluetooth modes and is widely used in fields such as the Internet of Things and wearable devices. When using the KT1025A chip, some users have encountered the problem that after setting the parameters of the chip, the Bluetooth signal cannot be searched by mobile phones or other devices. This problem is rather tricky because only by searching for the signal can a connection be established for data interaction. Possible Reasons Improper Chip Parameter Settings : The KT1025A is a chip with rich functions. Incorrect settings of parameters such as its working mode, transmission power, and broadcast interval may lead to search failures, similar to a...
