Description

Bone conduction earphone

Technical Field

The invention relates to the technical field of earphones, in particular to a bone conduction earphone.

Background

The air conduction speaker is used for transmitting sound waves (vibration signals) converted from the electric signals to the acoustic nerve. While bone conduction speakers are acoustic waves (vibration signals) converted from electrical signals, which are transmitted directly through bone to the acoustic nerve. The transmission medium of sound waves (vibration signals) is different. Headphones manufactured using these bone conduction techniques are referred to as bone conduction headphones. When the bone conduction earphone is worn and used, the ears are opened, the ears are not blocked, and the uncomfortable feeling of wearing the in-ear earphone is solved. Simultaneously, a series of health and health problems caused by sweat in ears during the movement of the earphone are avoided. Therefore, bone conduction speaker headphones are well suited for sports use. The open ears also guarantee the possibility of using headphones in dangerous situations. The ears are opened, and the change of the surrounding environment can be noticed when the earphone is used, so that the use is safer. Can hear environmental sound under driving, sports and other environments.

The prior professional sports teaching has the defects that the sports equipment comprises:

1. swimming teaching: there is a problem in that a coach cannot immediately correct or guide sports when teaching a school student to a crowd student. The original teaching method is that when a coach does not have auxiliary instruments, the coach stands in water or uses the swimming pool to make shouting teaching or to make shouting all pause, after guiding individual teams, the coach can continue training, and after teaching for one day, the coach has hoarse voice and serious voice. Some coaches are suitable for teaching with loudspeaker equipment, and have a certain effect, but have great influence on other people in the natatorium.

2. Track and field teaching: there is a problem in that a coach cannot immediately correct or guide sports when teaching a school student to a crowd student. The original teaching method is that when a coach does not have auxiliary instruments, the coach stands in the middle of a sports ground or on a track to make shouting teaching, and after one day of teaching, the hoarseness is serious. Some coaches use loudspeaker equipment for teaching, and although the coaches have a certain effect, the coaches have great influence on other people in the sports field.

3. Ice and snow movement teaching: there is a problem in that a coach cannot immediately correct or guide sports when teaching a school student to a crowd student. The original teaching method is that when a coach does not have auxiliary instruments, the coach stands in the middle of a sports ground or on a track to make shouting teaching or to make shouting all pause, after guiding individual teams, the teams can continue training, and after teaching for one day, the hoarseness is serious. Some coaches use loudspeaker equipment for teaching, but have a little effect, but have a great influence on other people in the sports field.

4. Ball game teaching: there is a problem in that a coach cannot immediately correct or guide sports when teaching a school student to a crowd student. The original teaching method is that when a coach does not have auxiliary instruments, the coach stands in the middle of a sports ground or on a track to make shouting teaching or to make shouting all pause, after guiding individual teams, the teams can continue training, and after teaching for one day, the hoarseness is serious. Some coaches use loudspeaker equipment for teaching, but have a little effect, but have a great influence on other people in the sports field.

5. Diving and pattern swimming teaching: there is a problem in that a coach cannot immediately correct or guide sports when teaching a school student to a crowd student. The original teaching method is that when a coach does not have auxiliary instruments, the coach stands on the side of a training field to carry out megaphone teaching or the whistle is greatly suspended, after the coach guides individual teams, the teams can continue training, and the teaching has great influence on the training effect.

6. Training of army and police: regardless of the species of the military such as sea, land, air, police, etc., there is a problem that a trainer cannot immediately correct or guide the movement when teaching class to a group learner.

The invention can achieve good effect as long as one-to-many teaching and training exists.

The current sports fan sports equipment has the defects that:

1. bicycle motion field: there is the problem of wearing in-ear earphone, when playing music, can't hear external sound, can't ensure riding safety. When many people in the open air ride training, if change such as route, speed etc. of riding takes place, team leader or coach can't inform other team member's problem in real time. The problem is solved by wearing the radio frequency machine by everyone originally, but the equipment is too heavy and too much, so that the exercise effect and the fun of sports can be greatly influenced.

2. Running motion: there is the problem that wearing in-ear earphone, when playing music, can't hear external sound, can't ensure safety. And the mobile phone is required to be worn, so that the problem of excessive equipment on the body is caused.

3. Outdoor hiking or climbing sports: in the field traveling process, the situation that the mobile phone signal is weak or no signal is frequently encountered, the leader cannot immediately inform the team member of some problems encountered in traveling, and the team member cannot hear the song from the Bluetooth of the mobile phone. The original radio frequency machine is worn by a plurality of people, the problems of too much equipment and overweight can be solved, the fun of sports can be influenced, and a plurality of potential safety hazards can be caused.

As shown in fig. 1, in order to prevent water from entering between the earphone body 1 and the bone vibrator 2, the earphone body 1 may be connected with the bone vibrator 2 through a glue overflow groove 13, and the glue overflow groove 13 is filled with silica gel.

Since the bone vibrator earphone is an external ear earphone, the bone vibrator is pressed on the periphery of the ear, and when the earphone is worn for a long time, blood stasis is easily generated, and in order to prevent a part of skin from being pressed for a long time, the blood stasis is generated. As shown in fig. 1, in one specific embodiment, the earphone body 1 is connected with the bone vibrator 2 through a rubber section 10, a micro-motor 11 is disposed in the earphone body 1, an eccentric wheel 12 is disposed in the rubber section 10, the micro-motor 11 is in transmission connection with the eccentric wheel 12 to control the eccentric wheel 12 to press the inner wall of the rubber section 10 so as to enable the bone vibrator to periodically contact and leave the ear, the micro-motor 11 is electrically connected with the lithium battery 4, and the micro-motor 11 is in signal connection with the main board 3. The micro motor can be started and shut down at intervals by the main board 3, and the motor can be started by a key.

As shown in fig. 1, in order to prevent water from entering the bone oscillator, the periphery of the bone oscillator 2 is wrapped with an eardrum silica gel sheet 21, and the eardrum silica gel sheet 21 is waterproof by dispensing (i.e. partially coating), so that the bone oscillator is well known to those skilled in the art, and the present invention will not be repeated. In addition, the screw in the earphone adopts stainless steel material plus waterproof silica gel circle to fix and waterproof, and the liquid crystal display can adopt 3M waterproof powerful gum to waterproof, and inner structure crosses line department and adopts waterproof glue to fix and waterproof.

While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
