Tonewinner manufactures car speakers 4 inch with bluetooth usb

1. Appearance characteristics

• The TY-B04-shaped water cup adopts an all-aluminum alloy body, and the surface is brushed and anodized, which can effectively prevent fingerprints from being retained. The front is a steel mask, which protects the speaker unit from damage and effectively softens the high-frequency burr. The back is a neatly arranged control panel with delicate, sensitive and tactile keys. The edges are carefully rounded, which can greatly reduce the diffraction caused by the treble on the front panel. The whole box is small and exquisite, elegant and stable, and full of technology.

2. Circuit and material design

• TY-B04 adopts the most advanced mid-to-high-end flagship Bluetooth audio chip ATS2825. ATS2825 is a high-performance Bluetooth V4.2 dual-mode Bluetooth audio solution Soc designed for the mid-to-high-end Bluetooth market. It highly integrates MCU, DSP and RF in a single chip. Large-capacity built-in RAM can meet the needs of different Bluetooth application solutions. The built-in DSP supports a variety of sound effects, while maintaining low power consumption and low-cost control during music playback.

• The power amplifier uses the AD82589 integrated digital/analog audio system solution produced by ESMT Jinghao in Taiwan. The chip integrates the digital/analog audio decoding system and the 24-segment audio EQ equalization circuit and embeds it to form a powerful audio processing power amplifier. Can provide 16bit to 24bit digital quantization, 44.1kHz to 192kHz multiple sampling frequency decoding.

• Tianyi's unique DSP audio correction algorithm makes up for the congenital deficiencies of the frequency response of speakers and physical crossovers, reduces the sense of musical burr, improves the balance of the sound, and enriches the details and lack of layers in the sound quality of the speaker.
