Product details

1. Product Introduction

The MLT-1230 is a high-performance SMD Piezo Buzzer, belonging to the classic categories of Passive Buzzer andPiezoelectric Buzzer. It is specially developed for engineering scenarios where designers need to build independent external drive circuits. Different from Piezoelectric Buzzer For Driver Circuit Built-in models with integrated drive modules, this passive component operates purely with external AC voltage drive, making it an optimal sound component for automated SMD assembly and space-saving PCB electronic devices.

In the industrial buzzer product ecosystem, thispiezo buzzer features differentiated advantages compared with Electromagnetic Buzzer and Mechanical Buzzer. It abandons the structural defects of electromagnetic and mechanical buzzers and adopts a piezoelectric ceramic deformation vibration sound generation principle. Equipped with a high-quality diaphragm structure consistent withMylar Speaker, it delivers clear, stable and pure warning sound without noise, ensuring excellent sound consistency for precision electronic equipment. Supporting a wide operating voltage range of 1V to 25Vp-p, it achieves a sound pressure level of ≥80dB at 10cm, perfectly balancing low power consumption and high loudness performance.

2. Product Features

1. Powerful Customization with Passive Design: As a professional Passive Buzzer without a built-in drive circuit, it provides higher design flexibility than conventional Piezoelectric Buzzer For Driver Circuit Built-in. Engineers can freely customize the drive frequency, sounding duration and sound characteristics to match personalized circuit solutions, offering superior system integration compatibility compared with ordinary electromagnetic and mechanical buzzers.

2. Stable Performance with Piezoelectric Core: Adopting exclusive piezoelectric ceramic materials for Piezoelectric Buzzer, the product generates sound through precise material deformation and diaphragm high-frequency vibration. It delivers uniform and clear sound quality, effectively avoiding common defects of Electromagnetic Buzzer (magnetic interference) and Mechanical Buzzer (mechanical abrasion and abnormal noise), thus realizing longer service life and higher operational stability.

3. Ultra-thin SMD Design for Automated Production: As a standardized SMD Piezo Buzzer, it features a compact footprint of 12mm × 12mm and an ultra-low height of only 3.0mm, which greatly saves PCB board layout space. It is fully compatible with reflow soldering processes, adapting to automated SMD production lines with high assembly efficiency and stable yield rates for mass production.

4. Premium Material with Excellent Weather Resistance: The housing is made of high-grade black LCP engineering material, featuring outstanding heat resistance, deformation resistance and aging resistance. It maintains stable mechanical performance in complex working environments and is not easily affected by ambient temperature and slight vibration, ensuring long-term stable sound output of equipment.

5. Wide Voltage Range and High Sound Pressure: Covering an ultra-wide operating voltage range of 1V-25Vp-p, it is compatible with most civil and industrial low-voltage circuits. Optimized with the Mylar Speaker diaphragm sound structure, it reaches ≥80dB sound pressure at 10cm, delivering loud and penetrating sound to meet various equipment audible and light warning requirements.

3. Product Application Scenarios

Relying on the core advantages of compact size, stable performance and customizable features, this piezo buzzer with passive SMD structure is widely applied in miniaturized, precise and automatically produced electronic devices, serving as an ideal replacement for traditional Electromagnetic Buzzer and Mechanical Buzzer. The main application scenarios are as follows:

1. Smart Home Devices: Smart sockets, thermostats, door and window sensors, smart lights and other small smart home products for equipment status indication, abnormal alarm and touch feedback sound.

2. Wearable and Portable Electronics: Smart bracelets, Bluetooth earphone charging cases, portable detectors, handheld temperature measuring devices and other space-constrained portable products.

3. Industrial Control Accessories: Small industrial control modules, sensor equipment, low-voltage control circuit boards and automated auxiliary equipment for operation reminder and fault early warning.

4. Automotive Mini Electronics: Automotive ambient lights, car chargers, small vehicle monitoring devices for status prompt and abnormal warning.

5. Medical and Consumer Electronics: Household medical detectors, beauty small appliances, remote controls and mini digital products for operation feedback and alarm prompting.

4. User Pain Point Solutions

1. Solve the poor customization problem of active buzzers: Mainstream Piezoelectric Buzzer For Driver Circuit Built-in on the market has fixed parameters with no adjustable sound frequency and tone, failing to meet personalized product design needs. As a flexible Passive Buzzer, it supports matching with external drive circuits to adjust sound parameters freely, perfectly adapting to customized R&D requirements.

2. Eliminate performance defects of electromagnetic and mechanical buzzers: Traditional Electromagnetic Buzzer suffers from electromagnetic interference and high power consumption, while Mechanical Buzzer has inherent problems of mechanical noise, abrasion and short service life. Adopting the piezoelectric sounding principle, this Piezoelectric Buzzer has no electromagnetic interference or mechanical wear, providing pure sound quality and longer service life to upgrade overall equipment quality.

3. Resolve PCB layout space shortage issues: Traditional pin-type buzzers are bulky, require manual welding and cannot adapt to automated production. This SMD Piezo Buzzer features an ultra-compact and thin design that fits miniaturized equipment layouts. Its reflow soldering compatibility greatly reduces labor costs and improves mass production efficiency.

4. Fix insufficient loudness and unstable operation of small buzzers: Ordinary mini buzzers often have low sound volume, uneven sound output and failure risks under high-temperature conditions. Equipped with the Mylar Speaker diaphragm structure and high-temperature resistant LCP housing, this product ensures sufficient and uniform sound output and stable operation in complex environments, avoiding weak sound and frequent equipment failures.

5. Improve poor voltage adaptability and low universality: Most conventional piezo buzzer has a narrow operating voltage range with limited device compatibility. With an ultra-wide 1V-25Vp-p voltage adaptation, this product is compatible with most low-voltage electronic devices, reducing procurement and inventory costs by supporting multi-category product R&D with a single component.
