Embodiment Construction

[0051] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application.

[0052] Embodiments of the present application provide a speaker, a speaker module and electronic equipment including the speaker. Loudspeakers are used to convert electrical signals into sound signals. The speaker forms a double-diaphragm structure by coupling the piezoelectric speaker core and the dynamic speaker core, and the diaphragm of the piezoelectric speaker core is set opposite to the diaphragm of the dynamic speaker core, sharing the front cavity, thereby complementing the mid-high frequency of the speaker. louder to increase the overall loudness of the speakers.

[0053] Wherein, the speaker can be independently installed on the electronic device, or can be used as the core of the speaker module, and installed on the electronic device as a whole along with the speaker module. The electronic device may be an electronic pr...

Abstract

The embodiment of the invention discloses a loudspeaker, a loudspeaker module and electronic equipment. The loudspeaker comprises a support, a first vibrating diaphragm, a first piezoelectric plate and a moving-coil loudspeaker core. The periphery of the first vibrating diaphragm is fixed to the support, and the first piezoelectric plate is fixed to the middle of the first vibrating diaphragm. The moving-coil loudspeaker inner core is fixed on the support, the moving-coil loudspeaker inner core and the first vibrating diaphragm are arranged in a spaced mode, the moving-coil loudspeaker inner core comprises a second vibrating diaphragm, the second vibrating diaphragm faces the first vibrating diaphragm, the second vibrating diaphragm, the support and the first vibrating diaphragm jointly define a front cavity, the support is provided with a sound outlet hole, and the sound outlet hole is communicated with the front cavity and the external space of the loudspeaker. The first vibrating diaphragm and the second vibrating diaphragm of the loudspeaker are oppositely arranged and share the front cavity, so that the medium-high frequency response of the loudspeaker is complemented, and the overall loudness of the loudspeaker is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of audio technology, and in particular to a speaker, a speaker module and electronic equipment. Background technique [0002] A dynamic speaker is a speaker that is widely used today, and is usually used in speaker modules and earpiece modules of electronic devices such as mobile phones and tablets. However, due to the small size of the dynamic speaker, its loudness is not enough; and because the dome of the dynamic speaker is thin and the material strength is not enough, the frequency response of the middle frequency is not enough. Contents of the invention [0003] The purpose of the present application is to provide a speaker, a speaker module and electronic equipment. The speaker combines the piezoelectric speaker core and the dynamic speaker core. The diaphragm of the piezoelectric speaker core and the diaphragm of the dynamic speaker core are set opposite to each other and share th...
