Overview

The main advantage of using electroacPy is its loudspeakerSystem class. It provides multiple tools such as:

• lumped element calculator for loudspeakers and enclosures, this includes basic alignment tools and Thiele/Small parameter loaders,

• bempp-cl wrapper to easily setup acoustic studies,

• tools to work with vibrometry data,

• automated evaluation setup for polar and spherical radiation, pressure fields and more,

• save/load functions to easily back-up and share projects.

A loudspeakerSystem object manages sub-objects through dictionaries. Each drive unit, enclosure, study and evaluation added to the system can be accessed through the corresponding dictionary:

• .driver[],

• .enclosure[],

• .crossover[],

• .vibrometry[],

• .acoustic_study[],

• .evaluation[],

• .results[].

A loudspeakerSystem object is defined as simply as:

import electroacPy as ep

#%% Create system object - with pre-defined frequency axis
system = ep.loudspeakerSystem()

The default frequency axis is defined from 20 Hz to 2500 Hz with 50 points. Alternatively, you can specify custom frequency axis, which must be a numpy array.

import electroacPy as ep
from electroacPy import gtb

#%% Create a system object with a custom frequency axis
frequency = gtb.freqop.freq_log10(10, 5000, 75)
system = ep.loudspeakerSystem(frequency)
