Embodiment Construction

[0010] The present invention has two embodiments, figure 1 is an example, figure 2 and image 3 is another embodiment.

[0011] Such as figure 1 As shown: the piezoelectric ceramic vibrator 1 is flatly attached to the inner side of the Bluetooth earphone box cover 2, and the outer surface of the box cover 2 is closely attached to the human skull. The position of the piezoelectric ceramic vibrator 1 can be pasted on the box cover 2, and the hollow slits 6 on three sides can be designed to allow the piezoelectric ceramic vibrator 1 to swing more. This structure is easy to install, takes up little space, can increase the vibration sensitivity of the vibrator, and improve the low-frequency effect.

[0012] Such as figure 2 , image 3 Shown: On the inside of the Bluetooth earphone box cover 2, one side of the piezoelectric ceramic vibrator 1 is fixed on the Bluetooth earphone battery 4 or the PCB board, the other side is covered with a layer of soft rubber pad 5, and a laye...

Abstract

The invention provides a piezoceramic bone-conduction oscillator mounting structure in a bone-conduction Bluetooth headset. One side of a piezoceramic oscillator is fixed on a battery or PCB printed circuit board of the Bluetooth headset, the other side is covered with a soft cushion layer, a soft rubber mat layer is added in the middle, a rectangular hole is designed in the headset case cover, and the soft cushion protrudes out of the headset case cover through the rectangular hole and contacts directly with a human skull. The piezoceramic bone-conduction oscillator mounting structure is convenient to mount, small in occupied area and good in oscillation transmission effect, and can improve the oscillation sensitivity of the oscillator, reduce sound leakage of the bone-conduction oscillator and improve the low frequency effect.

Description

technical field [0001] The invention belongs to the application of piezoelectric ceramic bone conduction technology in bluetooth earphones, and in particular relates to an installation structure of piezoelectric ceramic bone conduction oscillators in bone conduction bluetooth earphones. Background technique [0002] Bone conduction technology is being widely used in Bluetooth headsets. Using piezoelectric ceramic vibrators as bone conduction speakers for bone conduction Bluetooth headsets has more advantages than using traditional electromagnetic vibrators. Such as simple structure, thin thickness, light weight, etc., so far no relevant literature reports have been found. Contents of the invention [0003] The purpose of the present invention is to provide an installation structure of a piezoelectric ceramic bone conduction vibrator in a bone conduction Bluetooth headset, which has the advantages of convenient installation, small space occupation, increased vibration sens...
