This mobile creative mutual inductance speaker is a compact audio device for wired listening. It connects through a 3.5mm audio jack or a USB interface, covering common wired connection options.

Its 2.1 vocal tract is designed to deliver a stereo-style sound experience. The shell is made from plastic and measures 122 x 100 x 100mm. It is available in black and does not have a display screen. This description is based on the available source details; charging time, playtime, and water resistance are not stated.

Features and Construction

The speaker combines wired connection options with a built-in rechargeable battery. Its construction focuses on portable audio playback for personal use, with a plastic shell that keeps the overall unit manageable to carry and place.

Material and Build

The outer shell is made of plastic in a black finish. This material forms the housing for the speaker components and the internal battery. The plastic construction contributes to a lighter unit, which can be easier to move between locations than a heavier alternative. No additional materials are specified in the source text.

Size and Practical Fit

The appearance size is 122 x 100 x 100mm. These dimensions describe the physical footprint of the speaker and help you judge whether it will fit on a desk, shelf, or table. The compact shape is suited to spaces where a larger sound system would take up too much room. The source does not provide the weight.

Uses and Placement

This speaker is intended for mobile and creative audio use. It can be placed in a home, office, or similar indoor setting where wired playback is required. The connection methods and built-in battery support use with a range of devices that have a 3.5mm output or USB audio capability.

Event or Professional Use

For small events, presentations, or creative projects, the speaker can be connected via the 3.5mm audio jack or USB. The 3W output is suited to personal listening rather than large-room sound reinforcement. Its 2.1 vocal tract aims to provide a stereo-style experience for the listener. The source does not indicate suitability for outdoor public address use.

Everyday Home Use

At home, the speaker can be used for music, podcasts, or audio from a computer or phone with a compatible output. The built-in lithium battery allows it to be placed away from a power socket for a period, although the source does not state the battery life. The compact size makes it easy to position on a bedside table or desk.

Benefits and Buying Value

The main practical value comes from its wired connection options, built-in battery, and compact dimensions. These features support flexible placement and straightforward use without the need for a separate amplifier or permanent installation.

Reuse and Low Maintenance

The built-in lithium battery can be recharged, which reduces the need for disposable batteries. The plastic shell can be cleaned with a soft dry cloth. No specific maintenance schedule or battery lifespan is provided in the source text, so care should be kept simple and based on the stated materials.

Why Choose This Product

It offers a 3W output, a 40Hz-20KHz frequency range, and a 2.1 vocal tract in a black plastic enclosure. The stated 750 battery capacity figure is present, but the source does not specify the unit, so it is quoted as given. Charging time remains unspecified.
