Problems solved by technology

[0009] However, this technical solution also has the problem of taking up a large space, which is not conducive to the thinner and lighter structural design of mobile phones.
On the premise that the screen 01 of the mobile phone can produce a sufficiently large amplitude, there needs to be enough space between the two magnets, otherwise it will cause a collision between the magnet and the electromagnet 02, which will seriously affect the acoustic performance of the screen sound
For this reason, it will inevitably take up more space in the thickness direction of the mobile phone
[0010] In addition, the magnet is usually a whole piece of magnet, the magnetic field density of this kind of magnet is low, the utilization rate of the magnetic field is low, and the driving force of electronic products is small

Abstract

Disclosed in the present invention are a vibrating sound production apparatus and an electronic product. The apparatus comprises a housing, a fixed piece, and a driving assembly. At least a portion of the housing is configured to vibrate relative to the fixed piece. The driving assembly comprises at least one wire coil and a Halbach magnet, the wire coil being fixedly connected to the fixed piece and the Halbach magnet being fixedly connected to the housing, or the Halbach magnet being fixedly connected to the fixed piece and the wire coil being fixedly connected to the housing. The plane on which the wire coil is located is perpendicular to the portion of the housing used for vibration, the wire coil is positioned at a side portion of the Halbach magnet, an annular end surface of the wire coil faces the Halbach magnet, and the wire coil passes through the strengthened region of the magnetic field of the Halbach magnet.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a vibration and sound generating device and electronic products. Background technique [0002] The sound generating device is an important electro-acoustic transducer element in electronic products, which is used to convert the current signal into sound. With the rapid development of electronic products in recent years, the sound generating devices applied to electronic products have also been improved accordingly. [0003] The principle adopted by the traditional sound generating device for the handset of the mobile phone is that the diaphragm pushes the air to vibrate to produce sound. Recently, as the full screen has become the main development direction of mobile phones, how to realize the handset function without the design of the screen opening, and at the same time have a better listening experience, is currently facing a technical prob...
