Abstract

The invention discloses a sound production device and electronic equipment. The sounding device comprises a magnetic circuit system; The first vibration system comprises a first vibrating diaphragm and a first voice coil arranged on the first vibrating diaphragm, and the first voice coil is located on one side of the magnetic circuit system in the vibration direction; The second vibration system comprises a second vibration film and a second voice coil arranged on the second vibration film, the second voice coil is located on the other side of the magnetic circuit system in the vibration direction, and the first vibration system and the second vibration system vibrate and produce sound at the same time and produce sound in a sound production hole of the electronic equipment provided with the sound production device; And the phase difference of sound signals generated by the first vibration system and the second vibration system in the frequency band before 3kHz of the sounding hole isbetween [0, / 2].

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a sound generating device and electronic equipment. Background technique [0002] In the existing double-sided sound emitting devices, usually the two sides each have independent functions. For example, one side is used as a speaker and the other side is used as a receiver, and each is connected to an electronic device through a sound pipe, such as a different sound output position of a mobile phone, so as to emit sound to the outside. [0003] In such double-sided generating devices, both sides have low acoustic performance and low loudness. Especially when used as an external loudspeaker, the loudness of the speaker can no longer meet the needs of current users. [0004] Therefore, a new technical solution needs to be provided to solve the above technical problems. Contents of the invention [0005] An object of the present invention is ...
