Embodiment Construction

[0010] A vibration speaker with double voice coils and double magnetic fields for mobile communication, comprising at least a base 10, a magnetic steel 5, a voice coil 6, a magnetic cover 7, a spring plate 8, a splint 4, a sound film 3, a lead wire 9 and a terminal board 1 thereof, It is characterized by:

[0011] The magnetic steel 5, splint 4, and magnetic cover 7 are coaxially fixed on the spring plate 8, and the edge of the spring plate 8 is concentrically fixed on the shoulder of the inner wall of the base 10;

[0012] Below the magnetic cover 7, the coaxial line is fixed with an annular magnetic steel 14 clamped and fixed by the annular splint 12, and the outer periphery of the annular splint 12 is fixed with a mass ring 11;

[0013] The vibration coil 13 fixed on the bottom surface of the base 10 is coaxially located in the magnetic circuit formed by the ring magnet 14 and the magnetic cover 7 .

[0014] Wiring board 1 has contacts, is connected with voice coil 6, the ...

Abstract

The invention relates to a dual voice coil and dual magnetic field vibration loudspeaker and application thereof in a mobile phone. The loudspeaker is provided with a structure of a loudspeaker, and a structure of a vibrator on the other side, wherein the vibrator and the loudspeaker are integrated to replace the loudspeaker and a vibrating motor of the mobile phone simultaneously. The loudspeaker uses the same signal as a drive so that the designing and manufacturing difficulties are lightened and the cost is reduced simultaneously. Because the same signal drive is adopted, a vibration system can generate vibrations to be transmitted to the mobile phone in match with the sounding of the loudspeaker, and then the mobile phone transmits the vibrations to a hand of a user so that the user feels a bass vibration when the user hears an undertone.

Description

technical field [0001] In the International Patent Classification, the present invention belongs to other subclasses of acoustic-electromechanical sensors, that is, H04R, and particularly relates to vibrators and loudspeaker components for mobile phones. Background technique [0002] Mobile phones are rapidly gaining widespread use as a modern communication technology. Its vibrator usually uses an eccentric motor to generate vibration, driven by a dedicated signal. Its loudspeaker usually adopts a moving coil loudspeaker, so the two parts of the vibrator and the loudspeaker occupy two spaces respectively and require two different driving signals. This increases the design and manufacturing difficulty of the signal source main board. [0003] Mobile phones are not only used for communication, but also as music and video players. Its speakers usually use dynamic speakers, which have a narrow frequency range and lack bass due to volume and power limitations. Due to the mult...
