AI Technical Summary

Problems solved by technology

Because the diaphragm is not absolutely rigid, this pressure causes the diaphragm to deform, potentially degrading the sound quality of the speaker

Abstract

The invention discloses a membrane plate made of ceramic material. A dynamic loudspeaker driver, comprising a magnet system; a membrane which comprises a diaphragm (43) and a flexible annulus surrounding the diaphragm (43), the diaphragm (43) being movably mounted with respect to the magnet system by means of the annulus; a voice coil attached to the diaphragm and operatively coupled with the magnet system; a diaphragm plate (61) attached to the diaphragm, the diaphragm plate being made of or comprising a ceramic material.

Description

technical field [0001] The present invention relates to a dynamic speaker driver, a speaker comprising the dynamic speaker driver, and a mobile device such as a mobile phone comprising the speaker. Background technique [0002] A dynamic loudspeaker driver generally includes a magnetic circuit, a diaphragm movably mounted relative to the magnetic circuit, and a voice coil engaged with the diaphragm. The magnetic circuit system includes a magnet, and the voice coil is operatively coupled to the magnet. Generally speaking, a loudspeaker includes an enclosure and at least one dynamic speaker driver mounted in the enclosure. [0003] In operation, an electrical signal is applied to the voice coil, for example through an amplifier. The diaphragm then moves relative to the magnetic circuit system and relative to the housing in response to the electrical signal, thereby moving the air. The sound pressure level of the loudspeaker is based on the air moved by the diaphragm. [00...
