Xiaomi Unveils Pocket Guitar: A Magnetic Musical Accessory for the 18 Pro Series

Following the unveiling of its flagship Xiaomi 18 Pro series, Xiaomi has introduced an unexpected hardware companion: the Xiaomi Pocket Guitar. Designed to make creative use of the secondary rear display featured on the Xiaomi 18 Pro and 18 Pro Max, the magnetic fold-out gadget transforms the smartphone into a functional, pocket-sized musical instrument.

Available in sleek Black and Red color options, the Pocket Guitar magnetically snaps onto the back of the phone, aligning directly with the rear sub-screen when folded. When unfolded along its central hinge, it unfolds into a two-part physical controller featuring tactile chord buttons on one side and a textured strumming zone on the other.

Hardware Design: Dual-Sided Controller and Magnetic Stand

The Pocket Guitar is engineered with a multi-purpose folding architecture that blends gaming-controller tactile feedback with lifestyle utility:

• Split-Section Hinge: Opening the device reveals two distinct performance zones. The left section houses seven tactile chord buttons labeled with Roman numerals (I through VII), while the right wing features raised, micro-textured ridges that simulate guitar strings for rhythmic strumming.
• Dual-Direction Kickstand: Beyond its musical application, the accessory folds in the reverse direction to serve as an adjustable magnetic desktop stand. It supports both portrait and landscape viewing orientations for hands-free video streaming or video calls.
• Rear Screen Integration: When mounted over the Xiaomi 18 Pro’s rear AMOLED sub-screen, the phone displays real-time musical notations, chord progression charts, and interactive rhythm cues synced with the accessory.

Interactive Play Modes Powered by Changba

The musical experience is driven through Changba, a widely popular karaoke and social singing platform in China. After pairing the gadget via Bluetooth, users can access a dedicated performance dashboard featuring two primary playback styles:

• Chord Mode: Geared toward players with a basic understanding of chord charts. The left hand holds down the Roman-numeral chord keys (I–VII) to define harmonic roots, while the right hand strums across the textured ridges to trigger corresponding acoustic or electric guitar tones.
• Rhythm Mode: Designed for casual users and beginners. The software automatically handles chord progression changes in sync with the selected backing track, requiring the user only to maintain steady rhythmic strumming on the ridges to keep the song playing seamlessly.
• Pitch & Audio Customization: The companion software offers pitch shifting, tone presets (clean acoustic, overdrive, classical nylon), and access to a growing cloud library of licensed backing tracks.

Battery Endurance, Power Management, and Cross-Platform Parity

Despite its slim footprint, the Pocket Guitar carries dedicated internal electronics rather than relying on inductive power draw from the phone:

• 630mAh Internal Cell: The accessory houses a 630mAh lithium-ion polymer battery rechargeable via a standard USB Type-C port. Xiaomi rates the device for up to 30 days of battery life based on an average of one hour of daily playing time.
• Automated Power-Saving: To preserve charge, the unit enters low-power sleep mode after one minute of inactivity and automatically powers down completely after three minutes of idle time. Closing the folding cover triggers an automatic shutdown after 60 seconds.
• iOS Compatibility: While customized around Xiaomi’s secondary rear displays, the Pocket Guitar is not locked to Android hardware. Users on iPhones running iOS 14 or later can pair the accessory over Bluetooth through the Changba app to access full chord libraries, strumming modes, and pitch tuning tools.

Pricing and Availability

The Xiaomi Pocket Guitar is available for purchase in mainland China through Xiaomi’s official online store and Youpin lifestyle platform:

• Standalone Retail Price: CNY 599 (approximately $84 / ₹7,000).
• Promotional Bundle Price: Customers purchasing the accessory alongside a Xiaomi 18 Pro or 18 Pro Max can add the Pocket Guitar for a discounted price of CNY 499 (approximately ₹5,800).

By combining casual music gamification, physical kickstand ergonomics, and secondary-display hardware integration, the Pocket Guitar highlights Xiaomi’s continuing appetite for experimental smartphone accessories that extend beyond standard phone cases and charging bricks.
