2pcs Speaker 5W 4Ω Cavity Loudspeaker for Arduino Black 5cm

Description

Product Overview

The MakerHawk 2pcs Speaker 5W 4Ω Mini Cavity Loudspeaker is engineered for makers, hobbyists, and professionals who demand high‑quality audio in a compact form factor. Constructed from durable injection‑molded plastic, each speaker features a rectangular prism shape that maximizes internal volume while keeping the external dimensions minimal—measuring just 5 cm across. The dynamic driver utilizes a non‑paper diaphragm and an internal magnetic circuit, delivering a full‑range frequency response from 500 Hz to 20 kHz. Rated at 5 W power and 4 Ω impedance, the speakers can handle the output of most Arduino, Raspberry Pi, and small microcontroller audio amplifiers without distortion. The JST‑PH2.54‑2Pin interface provides a secure, solder‑free connection, simplifying integration into prototypes and final products alike. With a lightweight design of 55 grams per unit and a package size of 5.91 × 2.76 × 0.79 inches, the set is ideal for space‑constrained applications such as wearable devices, miniature robots, and compact advertising displays.

Usage

These speakers excel in a wide variety of electronic projects. In educational settings, they enable students to explore sound synthesis, voice prompts, and interactive audio feedback on Arduino‑based kits. For hobbyist robotics, the compact size allows integration into autonomous drones, line‑following robots, and obstacle‑avoidance platforms, providing audible alerts and status indicators. The robust plastic housing ensures reliable operation in indoor advertising machines, LCD‑TV monitor add‑ons, and game console peripherals where vibration resistance is essential. Additionally, the speakers are well‑suited for Raspberry Pi media centers, enabling clear playback of music, podcasts, and system notifications without the need for external amplification. Their waterproof rating is false, so they are best used in dry environments, but the sealed design protects against dust and minor impacts, making them a dependable choice for prototype enclosures and hobbyist labs.

FAQ

What voltage range can these speakers safely operate within?

The speakers are rated for a nominal 5 W power at 4 Ω, which typically corresponds to a voltage range of 4.5 V to 7 V when driven by common Arduino or Raspberry Pi audio amplifiers. Exceeding this range may cause distortion or overheating.

Can I use these speakers in a waterproof enclosure?

While the speakers themselves are not waterproof, they can be installed inside a sealed enclosure that protects them from moisture. Ensure the enclosure has proper ventilation to avoid heat buildup.

Do the speakers require a separate amplifier?

Yes, to achieve optimal sound quality and volume, it is recommended to pair the speakers with a small audio amplifier module compatible with 4 Ω loads, such as the PAM8403 or similar.

Is the JST‑PH2.54 connector compatible with other wire gauges?

The JST‑PH2.54 connector is designed for 22‑28 AWG stranded wire. Using wire within this gauge range ensures a secure fit and reliable electrical contact.

What is the warranty period for these speakers?

MakerHawk offers a limited one‑year warranty covering manufacturing defects. Customers can contact support for replacement or repair within this period.
