Problems solved by technology

This degrades the sound output of the speaker / receiver and introduces distortion since the EMF motors of the speaker / receiver don't have the resources to move the added mass properly; as they are designed to work only with their own mass

Abstract

An apparatus including a housing (12) having a sound hole (32); a sound transducer (36) in the housing (12); and a dust barrier (46) in the housing (12) between the sound hole (32) and the sound transducer (36). The dust barrier (46) has a deck (58) located in a path between the sound hole (32) and the sound transducer (36). The deck (58) comprises a dust collection pocket (60) configured to accumulate dust therein and prevent dust from passing through the deck (58) at the dust collection pocket (60). A sound aperture (A) is provided between the sound hole (32) and the sound transducer (36) such that sound passes by the dust collection pocket (60) between the sound hole (32) and the sound transducer (36).

Description

technical field [0001] The exemplary and non-limiting embodiments relate generally to protecting acoustic transducers and, more particularly, to protecting acoustic transducers from particulates. Background technique [0002] Devices such as, for example, mobile phones use dynamic speakers and / or receivers (microphones) to receive and reproduce audio signals such as speech, music and warning tones to the user. Such speaker / receivers are widely used in telecommunications as well as in automotive, military, medical and consumer appliances. Dynamic speaker / receivers have internal membrane and magnetic systems that are susceptible to external particles such as dust, metal particles, sand, etc.; collectively referred to herein as dust. The magnetic system attracts metal particles that can penetrate the speaker / receiver. Metal particles are very common in many workplaces, especially in developing countries. Metal particles are also commonly found in trouser pockets where keys r...
