Problems solved by technology

[0002] As the most important part of a smartphone, the screen has undergone earth-shaking changes in just a few years, and the screen-to-body ratio of mobile phone screens has also increased. In recent years, with the development of full-screen technology, higher The screen-to-body ratio has become the goal pursued by major mobile phone manufacturers, but because the traditional mobile phone must transmit the sound through the front opening, it has hindered the further development and improvement of the screen-to-body ratio. Non-porous requirements, so screen sound technology came into being

Embodiment 1

[0031] see Figure 1-5 , the present invention provides the following technical solutions: a novel screen sound exciter, including a vibrating assembly 8 and a stator assembly 9, the vibrating assembly 8 includes a magnetic conductive plate 1 and a magnetic steel group 2, wherein one side of the magnetic conductive plate 1 is connected with The magnetic steel group 2, the stator assembly 9 includes a coil 4, a flexible circuit board 5 and a lower bracket 6, wherein a flexible circuit board 5 is connected to the inside of the lower bracket 6, and a coil 4 is connected to the top of the flexible circuit board 5, and the flexible circuit board 5 is flexible. The circuit board 5 is electrically connected to the coil 4 , and the vibration component 8 is located above the stator component 9 .

[0032] Further, the magnet group 2 includes three magnets, and the three magnets are arranged side by side.

[0033] By adopting the above technical scheme, the S-level of the middle magneti...

Embodiment 2

[0046] This embodiment differs from Embodiment 1 in that further, the iron core group 3 includes three iron cores, one iron core is located inside the coil 4 , and the other two iron cores are respectively located on both sides of the coil 4 .

[0047] By adopting the above technical solution, the magnetic field lines around the coil 4 are concentrated by the iron core, and the intensity of the magnetic field is enhanced.

[0048] To sum up, the present invention connects the vibrating component to the screen, connects the stator component to the middle frame, and through the interaction between the stator component and the vibrating component, drives the screen to vibrate along the Z axis to achieve the effect of sounding, with a simple structure , easy to manufacture, good sounding effect, and high energy utilization rate; the invention connects three magnetic steels arranged side by side on the magnetic permeable plate, thereby increasing the magnetic field intensity generat...

The vibrationassembly is connected to the screen, the stator assembly is connected to the middle frame, the screen is driven to vibrate along the Z axis through interaction of the stator assembly and the vibrationassembly, the sound production effect is achieved, and the novel screen sounding exciter has the advantages of being simple in structure, convenient to manufacture, good in sound production effect and high in energy utilization rate.

Description

technical field [0001] The invention belongs to the technical field of sound exciters, and in particular relates to a novel screen sound exciter and a realization method thereof. Background technique [0002] As the most important part of a smartphone, the screen has undergone earth-shaking changes in just a few years, and the screen-to-body ratio of mobile phone screens has also increased. In recent years, with the development of full-screen technology, higher The screen-to-body ratio has become the goal pursued by major mobile phone manufacturers, but because the traditional mobile phone must transmit the sound through the front opening, it has hindered the further development and improvement of the screen-to-body ratio. Non-porous requirements, so screen sound technology came into being. Contents of the invention [0003] The purpose of the present invention is to provide a novel screen sound exciter to solve the problems raised in the above-mentioned background techno...
