ACOUSTIC ENGINEERING

 

Thirty years of intensive research into the micro acoustic properties of metals, plastics, ceramics and the combination of these materials place Sonitron ahead of the competition in terms of sound presentation for a given volume and power consumption.  This research has resulted in several patents and the specialised knowledge utilised in the development and manufacture of all our buzzers.

PLASTIC INJECTION

Sonitron studied the use of numerous plastic materials for buzzer housings, resulting in the use of the highest quality materials.  Sonitron has a fully automated plastic injection department, which guarantees full of all the dimensions and acoustic properties of the housings of our products.

 

MOULD DEVELOPMENT AND CONSTRUCTION

 

Sonitron develops and produces himself the mouldings for the plastic housings and pin terminals used in their buzzers.  This in-house knowledge and expertise in moulding technology enables Sonitron to manufacture customized products.

CNC MILLING MACHINE

 

The fully automatic Milling Station with 5 axis is used to create new prototypes and plastic injection moulds.  A continuous milling productivity is guaranteed due to the 16 load tool exchanger.

 

 

PRESSING AND CUTTING METAL PARTS

 

Sonitron develops specially shaped and formed membranes for use in their products.  These membranes are produces in-house, enabling to maintain the high quality in large quantities, required for mass production of membranes with specific resonant frequencies.

PICK AND PLACE MACHINE

 

The electronic circuits produced and incorporated in Sonitron's acoustic components are designed in-house and are fully automatically realised with the latest surface mount and soldering equipment.

 

 

AUTOMATIC GLUING

 

As the process of gluing the ceramic onto the membrane is of essential importance for the reproduction of the requested frequency, Sonitron developed special gluing equipment.  This equipment enables full control of perfect adhesion between the piezo disc and the membrane.

CAD/CAM EQUIPMENT

 

The latest software programmes and computing technologies are used for the in-house 3D design of PC-boards, metal parts, moulds and in-house made automation equipment.

 

 

ELECTRONIC DISCHARGE MACHINE (EDM)

 

Sonitron develops specially shaped and formed membranes for use in their products.  These membranes are produces in-house, enabling to maintain the high quality in large quantities, required for mass production of membranes with specific resonant frequencies.

TEST AND MEASUREMENT EQUIPMENT

 

The anechoic room provides acoustic isolation from all background noises.  The real time audio analyser can measure each type individually for frequency response, harmonic distortion and phase shift.  All parameters such as dB(A), frequency, supply voltage are programmable.  A printed copy of specific measurement reports is obtainable upon request.

 

 

FINAL QUALITY CONTROL

 

Final testing of Sonitron's products is done in a special pyramid shaped sound absorption environment, avoiding reflection and standing wave patterns.  This method guarantees very accurate SPL measurements.
