Abstract
The invention relates to a mobile phone accessory, in particular to a novel mobile phone sounding device. The mobile phone comprises a mobile phone screen, a mobile phone frame and a linear vibration exciter, wherein the linear vibration exciter is arranged between the mobile phone screen and the mobile phone frame. When the linear vibration exciter is used for inputting an audio signal, the exciter vibrates and drives a mobile phone screen or the whole mobile phone to vibrate to generate sound, so that the visual sound production and conversation functions are realized.
Description
Technical Field
The invention relates to a mobile phone accessory, in particular to a novel mobile phone sounding device.
Background
Mobile phones and consumer electronics generally have two sound generating devices, one being a speaker and the other being a receiver. The loudspeaker has larger power, and can realize the functions of music playing and hands-free conversation. The receiver has smaller power and is used for the ear to answer the call close to the mobile phone. However, the conventional receiver relies on air to conduct sound outwards through diaphragm vibration, and requires that the upper surface (screen surface) of the handset must be provided with openings to facilitate sound transmission outwards through air.
For example, the Chinese patent authorization publication number: CN 104618840B authorizes a receiver with high sound pressure output in 2017, 12, 15: the microphone comprises a microphone upper shell and a vibrating membrane, wherein the vibrating membrane is arranged in the microphone upper shell to form a cavity for outputting microphone sound pressure, a sound outlet is formed in the microphone upper shell, the front end of the sound outlet arranged in the microphone upper shell is of a rectangular structure, and the front end of the vibrating membrane is of a convex arc-shaped structure and extends to the outside of the sound outlet. This solution enlarges the area of the diaphragm in the case of a telephone receiver case of a well-defined size, but still requires the output position to be exposed to the air.
Disclosure of Invention
The invention aims to provide a novel mobile phone sound production device which can avoid the hole forming on the screen surface of a mobile phone and meet the development requirement and trend of the whole screen of the mobile phone by driving the mobile phone screen or the whole mobile phone to vibrate to produce and conduct sound outwards by the vibration of a linear vibration exciter. When the linear vibration exciter is used for inputting an audio signal, the exciter vibrates and drives a mobile phone screen or the whole mobile phone to vibrate to generate sound, so that the visual sound production and conversation functions are realized.
Preferably, the linear vibration exciter comprises an upper casing, a mass block, a magnetic frame, magnetic steel, a spring, a coil, an FPC board and a lower casing, wherein the upper casing is matched with the lower casing, the mass block is arranged between the casing and the lower casing, the mass block is matched with the magnetic frame, the magnetic frame is matched with the magnetic steel, the magnetic steel is matched with the coil, the spring is matched with the mass block, the coil is matched with the FPC board, and the FPC board is arranged between the upper casing and the lower casing. External signals enter the coil through a circuit on the FPC board, the coil generates a magnetic field through current, the magnetic steel impacts the magnetic frame under the action of the magnetic field, and the magnetic frame drives the mass block to vibrate to generate sound so as to achieve a sound production function.
Preferably, the vibration direction of the linear vibration exciter is perpendicular to the plane of the mobile phone screen. The vibration direction is perpendicular to the plane of the mobile phone screen, so that the connection between the mobile phone screen and the mobile phone shell can be ensured to be only subjected to forces in two directions perpendicular to the plane of the mobile phone screen, and the mobile phone screen and the mobile phone shell cannot be dislocated due to vibration.
Preferably, the linear vibration exciter is driven by an alternating current signal.
Preferably, the spring is a planar spring.
Preferably, the spring may also be a disc spring.
In summary, the invention has the following advantages: the vibration of the linear vibration exciter drives the mobile phone screen or the whole mobile phone to vibrate to generate and conduct sound outwards, so that the opening of the mobile phone screen surface can be avoided, and the development requirement and trend of the whole mobile phone screen are met.

Illustration of the drawings: 1-mobile phone screen, 2-mobile phone frame, 3-linear vibration exciter, 4-upper case, 5-mass block, 6-magnetic frame, 7-magnetic steel, 8-spring, 9-coil, 10-FPC board, and 11-lower case.
Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Example 1: as shown in fig. 1 and 2, a novel mobile phone sound production device includes a mobile phone screen 1, a mobile phone frame 2 and a linear vibration exciter 3, wherein the linear vibration exciter is arranged between the mobile phone screen and the mobile phone frame. The linear vibration exciter comprises an upper shell 4, a mass block 5, a magnetic frame 6, magnetic steel 7, a spring 8, a coil 9, an FPC board 10 and a lower shell 11, wherein the upper shell is matched with the lower shell, the mass block is arranged between the shell and the lower shell, the mass block is matched with the magnetic frame, the magnetic frame is matched with the magnetic steel, the magnetic steel is matched with the coil, the spring is matched with the mass block, the coil is matched with the FPC board, and the FPC board is arranged between the upper shell and the lower shell. The vibration direction of the linear vibration exciter is vertical to the plane of the mobile phone screen. The linear vibration exciter is driven by an alternating current signal. The spring is a plane type spring or a disc type spring and the like. When the linear vibration exciter is used for inputting an audio signal, the exciter vibrates and drives a mobile phone screen or the whole mobile phone to vibrate to generate sound, so that the visual sound production and conversation functions are realized. External signals enter the coil through a circuit on the FPC board, the coil generates a magnetic field through current, the magnetic steel impacts the magnetic frame under the action of the magnetic field, and the magnetic frame drives the mass block to vibrate to generate sound so as to achieve a sound production function. The vibration direction is perpendicular to the plane of the mobile phone screen, so that the connection between the mobile phone screen and the mobile phone shell can be ensured to be only subjected to forces in two directions perpendicular to the plane of the mobile phone screen, and the mobile phone screen and the mobile phone shell cannot be dislocated due to vibration.
It should be understood that this example is only for illustrating the present invention and is not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
