Description

Technical Field

[0001] This utility model relates to the field of electroacoustic transducer technology, and in particular to a speaker unit and electronic device with a camera. Background Technology

[0002] In existing electronic devices, speakers and cameras are typically separate components, handling audio output and image capture respectively. However, with continuous technological advancements and increasing demands for portability, versatility, and user experience, this separate design has gradually revealed some problems. One obvious issue is that the separate speakers and cameras occupy space within the electronic device, increasing its overall size and thickness. This hinders the development of thinner and smaller electronic devices, especially in mobile devices such as smartphones and tablets, where limited internal space needs to be utilized more efficiently to meet users' demands for portability.

[0003] Based on this, some speaker units integrate cameras, making the speaker unit and camera a single device. However, in this single device, the bottom of the yoke and central magnetic structure of the speaker unit is provided with a mounting slot for mounting the camera. The setting of the mounting slot will undoubtedly lead to a significant weakening of the magnetic field strength of the speaker unit, which will seriously affect the sound performance of the speaker unit.
