扬声器组件和电子设备Speaker Components and Electronics

技术领域technical field

本申请涉及发声装置技术领域,尤其涉及一种扬声器组件和一种电子设备。The present application relates to the technical field of sound generating devices, and in particular, to a speaker assembly and an electronic device.

背景技术Background technique

随着移动终端的迅猛发展,手机的各项性能都在不断提升,声音作为手机最基本的功能之一,也不断面临新的挑战和机遇,大音量、立体声的需求不绝于耳。但受制于手机空间的限制,多摄像头、大电池、轻薄化等趋势,扬声器可利用的空间越来越小,导致手机音效较差。With the rapid development of mobile terminals, the performance of mobile phones is constantly improving. As one of the most basic functions of mobile phones, sound is constantly facing new challenges and opportunities, and the demand for high volume and stereo is endless. However, due to the limitation of mobile phone space, multi-camera, large battery, thin and light and other trends, the space available for speakers is getting smaller and smaller, resulting in poor mobile phone sound.

相关技术中为实现双声道立体声的方案采用的是在手机顶部听筒部分设置一个扬声器,在手机底部设置一个扬声器,并使手机顶部的扬声器共用听筒的出声结构。具体地,手机顶部的扬声器在手柄通话模式时作为受话器使用,输入功率小,声音比较小,外放模式时,输入功率大,声音可以比较大。但手机顶部的扬声器是以整个手机的内部缝隙空间作为后腔,性能上相比手机底部的第二腔体会有所损失,再加上手机顶部的扬声器共用听筒的微缝出声通道,外放的效果相比手机底部的扬声器差很多,这样在声场调试的时候对手机底部的扬声器会有所压制,立体声效果差。In the related art, the solution for realizing two-channel stereo adopts a speaker at the top of the mobile phone and a speaker at the bottom of the mobile phone, so that the speakers on the top of the mobile phone share the sound output structure of the earpiece. Specifically, the speaker on the top of the mobile phone is used as a receiver in the handle call mode, and the input power is small, and the sound is relatively small. In the external playback mode, the input power is large, and the sound can be relatively loud. However, the speaker on the top of the mobile phone uses the internal gap space of the entire mobile phone as the back cavity, and the performance will be lost compared to the second cavity at the bottom of the mobile phone. In addition, the speaker on the top of the mobile phone shares the micro-slit sound channel of the earpiece, and the external sound is released. The effect is much worse than that of the speakers at the bottom of the mobile phone, so that the speakers at the bottom of the mobile phone will be suppressed during the sound field debugging, and the stereo effect will be poor.

因此,如何提出一种音效好的扬声器组件,以适用于手机等电子设备成为目前亟需解决的问题。Therefore, how to propose a speaker assembly with good sound effects to be suitable for electronic devices such as mobile phones has become an urgent problem to be solved at present.
