Description

Bone conduction earphone

[ technical field ] A method for producing a semiconductor device

The utility model relates to a bone conduction earphone technical field particularly, relates to a bone conduction earphone.

[ background of the invention ]

The bone conduction earphone converts an electric signal into mechanical vibration, and the mechanical vibration is transmitted to human ears through human tissues to generate auditory sense; bone conduction sound consumes more energy through human tissue than through air, as opposed to the classical way of sound conduction, where sound waves are generated by a diaphragm.

At present, the power of the bone conduction earphone is more than one time larger than that of the common earphone. The audio output of such devices as mobile phones, MP3, computers, etc. is almost incapable of driving bone conduction speakers to emit sound with normal volume. In order to meet the requirement that the bone conduction headset can normally work for more than 5 hours, at present, the lithium battery used by the binaural bone conduction headset at least needs to be more than 100mAh, and based on the requirement, the battery of the headset is usually large in size and needs to be balanced. There are 4 solutions for the binaural bone conduction headset currently on the market.

The first scheme is as follows: as shown in fig. 1, the battery main boards are respectively arranged at the left and right sides of the earphone; one side is provided with a battery, and the other side is provided with a mainboard. 11. 12 is a bone conduction speaker; 13 is a battery compartment, and 14 is a main board compartment; 15 is a head beam of the earphone; for the sake of beauty, the battery bins on the left and right sides are designed to be as large as the main board bin. The balance weight has the defects of needing balance weight, balancing left and right, large volume, certain weight and no portability.

Scheme II: as shown in fig. 2, the battery and one bone conduction speaker are combined into one module 21, and the main board and the other bone conduction speaker are combined into a module 22, and the two side modules are connected by a head beam 23. The disadvantage is that a weight is required to balance left and right, and the speaker part is too heavy to slip easily.

The third scheme is as follows: as shown in fig. 3, the battery and the main board are put together to form a control box, and the control box is arranged in the middle of the head beam. 31. 32 is a bone conduction speaker; 33 is an earphone head beam; and 34 is a control box. The appearance is not attractive, the head beam is too heavy, and the wearing experience is not good.

And the scheme is as follows: as shown in fig. 4, the battery and the main board are put together to form a control box, and the two bone conduction speakers on the head beam are connected through the connecting wires. 41. 42 is a bone conduction speaker; 43 is a rear earphone hanger; 44 is a wire; and 45 is a control box. The control box is required to be arranged outside, and the operation is very inconvenient.

Therefore, there is a need for a bone conduction headset that is lightweight, small, and comfortable to wear.
