The vivo Y300 is equipped with vivo’s loudest speaker to date, boasting a maximum volume increase of up to 600%, a peak sound pressure level of 91.7dB, and a sound transmission distance of up to 100 meters at maximum volume. Its shocking and loud external sound allows users to hear clearly and enjoyably in various scenarios. Based on the large sound-generating unit, vivo has also designed a 4cc professional acoustic cavity – the large cavity enables more sufficient air vibration, endowing the Y300’s external sound with super "explosive power". Meanwhile, the peak power of the speaker array reaches 4.5W, approximately 3 times that of the previous-generation Y200.

Since its launch, the vivo Y300 has been widely favored by major tech bloggers and consumers, especially for its outstanding external audio performance – it not only delivers loud volume but also excellent sound quality. We compared the external audio performance of the vivo Y300 and iPhone 15 Pro Max from both subjective and objective perspectives, and the results show that the vivo Y300 has a clear advantage in both aspects.

The vivo Y300’s stunning external audio performance would not be possible without the support of Awinic’s "Divine Combination" solution.
To achieve three-dimensional sound quality and sound effects, the vivo Y300 adopts Awinic’s audio solution – a "Divine Combination" of dual Smart K chips paired with Awinic’s "Divine Algorithm", awinic SKTune®. Based on Awinic’s unique analysis and understanding of the sound effects of electronic devices and the characteristics of speakers, the Smart K series audio power amplifier chips can be combined with awinic SKTune, Awinic’s fully independently developed "Divine Algorithm". This comprehensive "end-to-end audio hardware-software solution" effectively enhances sound quality; the integration of hardware and software makes the world of sound more vivid.
The latest Awinic Smart K series audio power amplifier equipped in the vivo Y300 incorporates Awinic’s proprietary Multi-Level AGC audio algorithm. This algorithm automatically adjusts the output power according to the intensity of the input signal, ensuring pure and lossless sound quality at any volume. In addition, its I2C control offers broad compatibility and flexible configuration options, enabling it to easily adapt to various speaker load environments and seamlessly integrate into various consumer electronic devices, demonstrating strong adaptability and convenience. Most notably, the latest Smart K series features Awinic’s new-generation patented technology – Smart Adaption, which delivers ultra-high working efficiency and extremely low standby power consumption, contributing to the ultra-long battery life of the vivo Y300.
Batteries in portable products have also undergone new changes – silicon-anode batteries have begun to be widely used in portable devices. Compared with traditional lithium-ion batteries, silicon-anode batteries have higher energy density and a wider power supply voltage range, which brings certain challenges and new requirements for audio power amplifiers. The latest Awinic Smart K series audio power amplifier is specifically designed for the low-voltage application of silicon-anode batteries, supporting lower operating voltages to extend the product’s battery life.
