Planar series magnetic circuit double sided sounder

Abstract

The invention discloses a plane series connected magnetic circuit double side sounder. It includes: box shell where the plane series connected magnetic circuit is located in; the first shaking section that forms the first sound by the magnetic field in the first working magnetic interstice when the component of the first shaking section is impressed the first external sonic signal; the second shaking section that forms the second sound by the magnetic field in the second working magnetic interstice when the component of the second shaking section is impressed the second external sonic signal; the first external sonic signal and the second external sonic signal is impressed by the connector themselves. The sounder includes receiver and loudspeaker. One side is the loudspeaker that can send out music, and the other side is receiver that can deliver speech sound. The invention can satisfy the rigor request of the microminiaturization and high efficiency and multi-function of the communication electro-acoustic component as well as other special request of dense structure, low flux leakage, high sensitivity of the electro-acoustic component.

Description

technical field [0001] The invention relates to a sounding device, in particular to a double-sided sounding device which adopts a planar series magnetic circuit, and is provided with working magnetic gaps and independent vibrating components on the front and back sides. Background technique [0002] Mobile phones, IP phones, miniature terminal equipment, palmtop computers, miniature transmitting and receiving devices, and small cordless telephones require both a receiver to restore voice and a sounding device to arouse the user-speaker or buzzer. [0003] Under normal circumstances, the receiver for transmitting voice and the buzzer for buzzing sound use two independent devices. But since creating the ringing tone of the mobile phone with loudspeaker replaying chord tone recently, the ringtone craze is out of control since then. In order to reproduce wonderful music, mobile communication product manufacturers immediately turned around. Most mobile phones no longer use buzze...

AI Technical Summary

Problems solved by technology

[0004] At present, some of the known multifunctional miniature electroacoustic devices use a group of vibrating parts to realize the functions of both a receiver and a speaker; The problem is: the receiver transmits voice, and the user listens to it close to the ear; while the speaker transmits ringing sound or music, which is far away from the human ear, and the acoustic performance requirements of the two are very different.

The internal disadvantages of the internal magnetic circuit, such as the low space utilization rate and insufficient sensitivity, and the large magnetic flux leakage of the external magnetic circuit, make its structural design and application subject to many restrictions.
