Mobile Creative Mutual Inductance Speaker with USB, 3.5mm Jack and 3W Output

This mobile creative mutual inductance speaker is a compact audio unit that connects through USB or a 3.5mm audio jack and runs from a built-in 750 lithium battery. It delivers 3W output power with a 40Hz-20KHz frequency response and a 2.1 vocal tract. The signal-to-noise ratio is at least 70dB, and Bluetooth protocol 2.1 is supported for wireless pairing. The shell is made from plastic in black, and the appearance size is 122 x 100 x 100 mm. There is no display screen. This description covers only the details provided in the source information, so no further performance claims are made.

Features and Construction

The speaker combines wired and wireless connection options in a simple plastic housing. The available data focuses on connection type, battery, output power, frequency range, signal-to-noise ratio, vocal tract, Bluetooth protocol, shell material, dimensions, and colour. No additional construction details are supplied.

Material and Build

The shell material is plastic, finished in black. Plastic is a common choice for portable audio devices because it keeps the overall weight down, which is useful when the speaker is moved between rooms or taken on short trips. The source text does not state any impact resistance, waterproof rating, or recycled content, so those claims are not made here. The black colour gives the speaker a neutral appearance that can sit on a desk, shelf, or counter without drawing attention. The 2.1 vocal tract is listed as part of the audio design, and the unit has no display screen. All construction details in this section come directly from the provided specifications.

Size and Practical Fit

The appearance size is 122 x 100 x 100 mm. That footprint is small enough for a desk, bedside table, or kitchen shelf, but the source does not give a weight, so portability is described only in terms of dimensions. The 122mm width, 100mm depth, and 100mm height suggest a roughly block-shaped unit that does not need much surface area. No carry case, strap, or mounting bracket is mentioned, so placement is limited to flat surfaces. The absence of a display screen means there is no screen area to protect or clean beyond the main plastic shell. These measurements are the only dimensions provided, and no other size variants are stated.

Uses and Placement

This speaker is designed for listening to audio from devices that support USB, a 3.5mm audio jack, or Bluetooth protocol 2.1. It can be used at home or in a small workspace where a compact unit is preferred. The source data does not describe outdoor use, water resistance, or party-level volume, so those scenarios are not suggested.

Event or Professional Use

With a 3W output and a 2.1 vocal tract, the speaker can handle speech and background music in a small room or booth. The signal-to-noise ratio of at least 70dB helps keep hiss and hum low when the volume is turned down, which is useful for presentations or video calls where clear speech matters. The 40Hz-20KHz frequency response covers the range needed for voice and most music. The built-in 750 lithium battery allows the unit to run without being plugged into a wall outlet, but the source does not state battery life in hours, so no runtime estimate is given. Bluetooth protocol 2.1 provides a wireless option for compatible devices.

Everyday Home Use

At home, the speaker can be placed on a desk, shelf, or counter and connected by USB or the 3.5mm audio jack. The plastic shell can be wiped with a soft dry cloth, and the lack of a display screen keeps the front simple. The 122 x 100 x 100 mm size means it does not take up much room next to a laptop or monitor. The 3W output is suited to personal listening rather than filling a large room, based on the stated power figure. No remote control, app, or voice assistant is mentioned in the source text. The black finish is the only colour listed.

Benefits and Buying Value

The main practical benefit is the combination of wired and wireless connection types, backed by a built-in rechargeable battery and a compact plastic body. The source text does not provide price, warranty, or long-term reliability data, so value is described through the stated features only.

Reuse and Low Maintenance

The built-in 750 lithium battery can be recharged through the USB connection, which reduces the need for disposable batteries. The plastic shell can be cleaned with a soft dry cloth, and there are no separate grille or fabric parts mentioned that would need special care. Because the source does not list a battery lifespan or replacement procedure, no claims are made about how many charge cycles the battery will last. The lack of a display screen means there is no screen to scratch or replace. These points are limited to the information provided and do not imply any specific maintenance schedule.

Why Choose This Product

This speaker is a reasonable choice if you need a small black unit that accepts USB, a 3.5mm audio jack, and Bluetooth protocol 2.1, and that runs from a built-in 750 lithium battery with 3W output. The 40Hz-20KHz frequency response, signal-to-noise ratio of at least 70dB, and 2.1 vocal tract are all stated specifications, not subjective claims. The 122 x 100 x 100 mm size makes it easy to fit on a desk or shelf. No comparisons to other brands are made because the source does not support them. The product is defined by the measurements and features listed in the source text.
