Murata launches ultra low-profile surface mount 2.4 kHz piezo sounders

Murata today announced the expansion of its PKLCS family with two new 2.4 kHz SMD piezoelectric sounders aimed at white goods, portable, industrial, and automotive applications. Both the consumer part PKLCS1212E2400-R1 and the automotive/industrial part PKLCS1212E24A0-R1 are available in low profile surface mount packages. They have a 5dB increase in sound pressure level compared to previous Murata devices, and are fully reflow solder compatible. They are ideally suited for applications that need to minimize the use of leaded components or have all components be low profile.

Murata announces mass production of world’s thinnest waterproof piezoelectric speaker

Murata today announced it has commenced mass production of the ultra thin VSLBG2216E waterproof piezoelectric speaker. With a thickness of just 0.9 mm it is believed to be the world’s thinnest IPX7 speaker. Designed for consumer electronics applications, it is unlike other similar devices in that it does not require any additional waterproof membrane to be applied during end-product manufacture. Such additional membranes increase product time, costs and impacts the audio output quality of the speaker. The VSLBG2216E series offers a flexible, space saving and cost effective design together with a higher quality of music reproduction.

World’s smallest and low-profile high pressure air pump with piezoelectric technology

Murata today announced the MZB1001 microblower, a miniature piezoelectric air pump designed for a wide range of household consumer products. Measuring just 20 x 20 x 1.85 mm (excluding nozzle), the MZB1001 microblower is believed to be the smallest air pump in the market. Using a piezoelectric diaphragm, which vibrates up and down when a sine wave voltage is applied, the vibrations force air into the microblower and out through a nozzle on the top of the device. The microblower can produce typical airflow rates of up to 0.8 litres per minute and typical air pressure up to 1.5 kPa when driven by a 15 Vp-p 25 kHz signal. The piezoelectric diaphragm has been optimized for operation above the normal audible range and is typically driven by a 24 – 25 kHz signal.

Murata improves acoustic characteristics of world’s thinnest piezoelectric speaker

Murata today announced it has enhanced the audio characteristics of its ultra thin piezoelectric speaker. Measuring just 0.5 mm in thickness, the VSLBP2115E1100 series is believed to be the world’s smallest piezoelectric speaker. By optimizing the product’s structure and the use of new materials it has been possible to reduce distortion and increase sound pressure level without any change in the speaker’s size. Distortion has been reduced by 50 % in the voice frequency region of 2 to 4 kHz. Sound pressure improvements have been made in the low frequency regions of 1 kHz and below.

Murata Introduces World's First Ultra-Thin Waterproof Piezoelectric Speaker

Hoofddorp, Netherlands: Featuring a thickness of only 0.9mm, Murata has launched the world’s first ultra-thin waterproof piezoelectric speaker. Based on Murata’s proprietary piezoelectric technology, the speaker is waterproof to IPX5/IPX7. The speaker measures 19.5 by 14.1 by 0.9mm; its rectangular shape reduces dead-space from designs while its ultra-thin dimensions contribute to greater freedom in equipment design.

Piezo sound components offer low profile, low current solution for automotive and consumer applications

Fleet, UK: Murata's piezo sound components are available in low-profile SMD packaging for automotive and consumer electronics. Compared to magnetic/dynamic sound components, piezo sounders and buzzers consume very little current, are lightweight and reduce the amount of components needed in the drive circuit as they can be driven directly from an IC. There is no magnetic noise interference from piezo parts as the sound component is based on a piezoelectric ceramic diaphragm. The RoHS compliant parts are high impedance (1 to 5kOhm) and are available in SMD packages to help keep assembly costs low.

Murata's ultra-thin rectangular piezo speakers replay music and voice with flat frequency response

Hoofddorp, Netherlands: The latest addition to Murata's family of piezoelectric ceramic speakers is ultra-thin, just 1.2mm in thickness, with side ventilation in its sturdy metal housing helping to keep the thickness down. The VSLBP1913E series' unique rectangular shape improves its frequency response and minimises 'dead-space' in handheld devices. The series' flat frequency response makes it suitable for the replay of voice and music in today's thin and stylish mobile phone handsets.
