Abstract

Purpose

A balanced armature receiver (BAR) as a special type of electromagnetic acoustic transducers plays a significant role in reproduction of music and speech, active noise control in modern hearing aid and in contemporary in-ear monitors. This paper aims to present a static analysis of the balanced armature receiver based on the lumped network approach (LNA) and the finite element method (FEM).

Design/methodology/approach

In this paper, the LNA and two-dimensional FEM are applied to model deflections of the BAR’s armature from the equilibrium position. Results of calculations are compared with measurements.

Findings

The derived analytical formulas and developed procedure allow for calculation of the armature deflection.

Originality/value

Comparing to the previous papers, the reluctance’s nonlinearity of the armature has been considered.

Abstract

This chapter thoroughly explores the intersection of family entrepreneurship, cultural dynamics, and emerging markets, with a specific focus on the United Arab Emirates (UAE). Examining the entrepreneurial behaviour of family firms, it delves into how these enterprises navigate cultural intricacies, seize emerging market opportunities, and contribute to local and global entrepreneurship ecosystems. The dynamic interplay between family dynamics and entrepreneurial pursuits is scrutinized, unravelling influences on resource allocation, succession planning, risk-taking, and innovation within UAE family firms. This exploration contributes valuable insights into the evolving landscape of family entrepreneurship, serving as a resource for researchers, policymakers, and practitioners. The research employs a comprehensive methodology involving case studies, shedding light on how these enterprises adapt, pivot, and exhibit resilience in response to the challenges and opportunities presented by emerging markets. Case studies provide valuable insights into the strategies employed by UAE family firms, contributing to a nuanced understanding of the evolving landscape of family entrepreneurship. This chapter serves as a valuable resource for researchers, policymakers, and practitioners seeking insights into the intricate interplay of family entrepreneurship, cultural dynamics, and emerging markets.
