Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0047] At the same time,...

Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a magnetic circuit system and a vibration system, the magnetic circuit system is provided with a magnetic gap, the magnetic circuit system is hollow to define an accommodating space, the vibration system comprises a diaphragm assembly, a voice coil and a framework, the diaphragm assembly is located in the accommodating space, and the voice coil is located in the framework. The diaphragm assembly is provided with a magnetic gap, the voice coil is inserted in the magnetic gap, one end of the skeleton is connected with the diaphragm assembly, the other end of the skeleton extends into the magnetic gap and is connected with the voice coil, and the voice coil drives the diaphragm assembly to vibrate through the skeleton. According to the sound production device provided by the invention, the vibration radiation surface is placed in the middle of the magnetic circuit system, and the voice coil and the vibration radiation surface are connected through the framework to transmit the motion load, so that the thickness size of the sound production device is greatly reduced, the high-frequency resonance is effectively reduced, the acoustic performance is improved, and the sound production device is convenient to process and assemble.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device and electronic equipment using the sound generating device. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for the sound quality of electronic equipment, and the volume of sound-generating devices in electronic equipment is affected by the appearance and structure of electronic equipment, and its volume is also getting smaller and smaller. As an important and indispensable functional component of electronic equipment, the sound-generating device is an important part of the thin and light design of electronic equipment, so it is extremely important for the thin and light design of the sound-generating device. [0003] In the related art, in order to reduce the volume of electronic equipment, a sound-generating device is proposed. The sound-generating device ...
