Speaker unit and electronic equipment

Abstract

The invention provides a loudspeaker unit and electronic equipment. The loudspeaker unit includes a basin frame, a magnetic circuit assembly and a vibration assembly; the magnetic circuit assembly is fixed in the basin frame, and the magnetic circuit assembly has a magnetic gap; the vibration assembly includes a voice coil, a second A diaphragm and a dome, the first diaphragm is respectively connected to the basin frame and the dome, and one end of the voice coil is connected to the dome and at least partially suspended in the magnetic gap, so as to separate the inner space of the basin frame into the voice coil The inner inner cavity and the outer cavity located outside the voice coil, the magnetic circuit assembly is used to drive the voice coil to move to make the first diaphragm sound; wherein, the dome is provided with holes connected to the inner cavity and the outer cavity respectively. connection slot. During the use of the speaker unit provided by this embodiment, the airflow in the inner cavity can exchange gas with the outer cavity and / or the external space through the connecting groove, the structure is simple, and the high-frequency sensitivity of the speaker unit is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of loudspeakers, in particular to a single loudspeaker and electronic equipment. 【Background technique】 [0002] Speakers, as an important component, are widely used in various portable electronic devices such as mobile phones, tablet computers, and portable game consoles. In a traditional loudspeaker, the voice coil drives the diaphragm to produce sound by driving the dome to move, and the voice coil also separates the internal space of the speaker into two parts. During the sound production process, the airflow inside the cavity of the voice coil cannot communicate with the outside world. The high-frequency sensitivity of the loudspeaker is somewhat affected. Therefore be necessary to design a kind of novel loudspeaker, to change the status quo. 【Content of invention】 [0003] In view of this, the present invention provides a loudspeaker unit and electronic equipment, compared with traditional loudsp...
