Loudspeaker unit and electronic device

Abstract

The invention provides a loudspeaker single body and electronic equipment. The loudspeaker single body comprises a basin stand, a magnetic circuit assembly and a vibration assembly. The magnetic circuit assembly is fixed in the basin stand and is provided with a magnetic gap; the vibration assembly comprises a voice coil, a first vibrating diaphragm and a dome; the first vibrating diaphragm is connected to the basin frame and the dome; one end of the voice coil is connected to the dome and at least partially suspended in the magnetic gap, so that the internal space of the basin frame is divided into an inner cavity located on the inner side of the voice coil and an outer cavity located on the outer side of the voice coil; the magnetic circuit assembly is used for driving the voice coil tomove to make the first diaphragm produce sound; and connecting grooves which are respectively communicated with the inner cavity and the outer cavity are formed in the globe roof. In the use process of the loudspeaker monomer provided by the embodiment of the utility model, the air flow in the inner cavity can exchange air with the outer cavity and / or the external space through the connecting groove, the structure is simple, and the high-frequency sensitivity of the loudspeaker monomer 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...
