NO. XDEC-57Y04T21ND26
Speaker Driver Product Introduction
This 57.3×21.2mm round mid-range alarm speaker, featuring a blue zinc-plated metal frame and a neodymium magnet, delivers prominent mid-frequency performance optimized for voice and alert tones. It has a rated power of 5W (7W max) and 4Ω impedance. The high-energy neodymium magnet system ensures excellent sensitivity and dynamic response across its operating band. Designed with a one-piece PET plastic diaphragm and a black plastic dome, sealed using waterproof adhesive, the speaker offers front-facing water resistance. This driver is specifically tuned for enhanced mid-to-high-frequency output, with a fundamental resonance frequency (Fo) as high as 565Hz.
Key Features & Benefits:
Neodymium Magnet: Provides a strong magnetic force in a compact, lightweight package, resulting in high efficiency and fast transient response.
Plastic Diaphragm & Dome Design: The hard and relatively heavy one-piece PET diaphragm and plastic dome are engineered to prioritize clear, sharp mid and high-frequency reproduction, making it ideal for generating attention-grabbing alarm sounds.
High Fo (565Hz): The high fundamental resonance frequency specifies its optimized bandwidth for mid-range applications, with an effective frequency response extending up to 10kHz.
Measured Performance: Average sensitivity is 85dB SPL at 0.5m with 1W input.
Ideal Applications:
Perfectly suited for audio alerts and voice announcements in devices such as:
Audio-Visual Alarms
Dumping Truck Backup Alarms
Voice Alarm Systems
Voice Announcement Systems
Doorbells
Surveillance Equipment
Outdoor Alerters

Speaker Frequency Response Curve
The frequency response curve helps us understand the speaker's performance across different frequencies, in cluding treble,midrange, and bass. Fluctuations on the curve indicate sound quality in specific ranges. A flatter curve suggests a more balanced output, while larger fluctuations indicate volume changes at certain frequencies.
