Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically providing a headphone with balanced ear pressure. Background Technology

[0002] Atmospheric pressure in high-altitude areas is much lower than in plains. To prevent the health of people living and working in high-altitude areas from being affected by low air pressure, pressurized buildings have been developed. The air pressure in the transition chamber of a pressurized building is close to the plains level and higher than the outdoor air pressure. According to relevant research, considering individual health status, age, and individual differences, the normal range of ear pressure that the human body can tolerate is 0.8~4 kPa. When people enter or exit the transition chamber, the ear pressure exceeds the normal tolerance range, which can cause ear discomfort. Current methods for equalizing ear pressure in environments with changing pressure involve actively or passively opening the Eustachian tube through specific actions such as swallowing to balance the pressure between the external environment and the middle ear cavity, thus relieving ear discomfort. However, for people with impaired Eustachian tube function and in situations where the change in environmental air pressure is not sudden, the body needs too long to adapt, which can cause ear discomfort and, in severe cases, may even lead to barotrauma of the middle ear.

[0003] In summary, this utility model provides a headphone with balanced ear pressure to solve the problem of ear discomfort caused by entering and exiting environments with changing pressure. Utility Model Content

[0004] The purpose of this invention is to provide a headphone with equalized ear pressure that can automatically adjust the ear pressure balance according to changes in ambient air pressure, alleviating ear discomfort when entering or leaving environments with changing pressure and preventing barotrauma to the middle ear.

The headband of the headphones is provided with in-ear earplugs at both ends, and the earplugs are covered by the headphone cover. The ear pressure equalization device includes a vent tube and a ball valve. The vent tube connects the outdoor vent on the outside of the headphone cover to the in-ear earbud. The ball valve is movably disposed inside the vent tube.

[0005] Furthermore, the in-ear earplug is provided with a vent hole, which is connected to a vent tube.

[0006] Furthermore, the vent pipe includes a main pipe and a bypass pipe. The main pipe includes a straight pipe section and a U-shaped pipe section arranged in series, and the U-shaped pipe section is arranged in parallel with the bypass pipe.

[0007] Furthermore, the U-shaped pipe segment includes an inlet section A, an intermediate section C, and an outlet section B connected in sequence, wherein the diameters of the inlet section A and the outlet section B are smaller than the diameter of the intermediate section C.

[0008] Furthermore, the ball valve is located in the middle section C of the U-shaped pipe section; the ratio of the diameter of the ball valve to the diameter of the U-shaped pipe section is in the range of 1:1.2-1:1.5.

[0009] Furthermore, a manual vent valve switch is provided on the outside of the earphone cover, and the manual vent valve switch is connected to a bypass pipe.

[0021] Example See Figure 1 and Figure 2This embodiment provides a headphone with balanced ear pressure, including a headband 1, in-ear earplugs 2, a headphone cover 3, and an ear pressure equalization device 4; the headband 1 has in-ear earplugs 2 at both ends, and the headphone cover 3 covers the outer periphery of the in-ear earplugs 2; the headphone cover 3 includes a shell 3.2, and an outdoor vent 3.1 is provided on the outer side of the shell 3.2; The ear pressure equalization device 4 includes a vent tube 4.1 and a ball valve 4.2. The vent tube 4.1 is connected to an outdoor vent 3.1 and an in-ear earplug 2. The ball valve 4.2 is movably disposed inside the vent tube 4.1.

[0022] The in-ear earplug 2 is provided with a vent hole, which is connected to the vent tube 4.1. External airflow can enter the external auditory canal through the outdoor vent 3.1, the vent tube 4.1 and the vent hole in sequence.

[0023] See Figure 2 The vent pipe 4.1 includes a main pipe 4.1.1 and a bypass pipe 4.1.2. The main pipe 4.1.1 includes a straight pipe section and a U-shaped pipe section arranged in series. In this embodiment, the straight pipe section is connected to both ends of the U-shaped pipe section to connect the outdoor vent 3.1 with the U-shaped pipe section and the U-shaped pipe section with the vent hole. The U-shaped pipe section and the bypass pipe 4.1.2 are arranged in parallel.

[0024] In this embodiment, the U-shaped tube segment includes an inlet segment A, a middle segment C, and an outlet segment B connected in sequence. Preferably, the diameters of the inlet segment A and the outlet segment B of the U-shaped tube segment are smaller than the diameter of the middle segment C, so as to reduce the airflow from the room into the ventilation tube 4.1 and from the ventilation tube 4.1 into the external auditory canal, and avoid causing ear discomfort.

[0025] In this embodiment, the ball valve 4.2 is located in the middle section C of the U-shaped pipe segment. Under normal conditions, the internal and external pressures are balanced, and the ball valve 4.2 is located at the lowest point of the middle section C. When the external pressure gradually increases, the ball valve 4.2 floats to the left (based on...). Figure 2 External airflow enters the external auditory canal through the outdoor vent 3.1, vent pipe 4.1, and vent hole, thereby releasing ear pressure. Changes in airflow cause the ball valve 4.2 to float up and down inside the pipe. The presence of the ball valve 4.2 not only increases the airflow resistance loss, but its up-and-down movement also causes the cross-sectional area to change continuously, increasing the airflow velocity difference and resulting in the slow release of ear pressure.

[0026] Preferably, the ratio of the diameter of the ball valve 4.2 to the diameter of the U-shaped pipe section is in the range of 1:1.2-1:1.5, so as to satisfy the vertical floating of the ball valve 4.2 in the pipe.

[0027] The earphone cover 3 is provided with a manual vent valve switch 4.3 on the outside. The manual vent valve switch 4.3 is connected to the bypass pipe 4.1.2. By pressing the manual vent valve switch 4.3, the valve is opened to quickly release the ear pressure and achieve ear pressure balance quickly.

[0028] In this embodiment, the over-ear pressure balanced headphones further include a control box 5 and a bone conduction microphone 6. The control box 5 is disposed on the headphone cover 3, and the bone conduction microphone 6 is disposed inside the headphone cover 3. The control box 5 is electrically connected to the bone conduction microphone 6.

[0029] Preferably, there are two control boxes 5 and two bone conduction microphones 6. The two bone conduction microphones 6 are symmetrically arranged inside the two headphone covers 3, and the control box 5 and the bone conduction microphones 6 are arranged in a one-to-one correspondence.

[0030] In this embodiment, the control box 5 integrates a signal amplifier, a Bluetooth communication module, a storage chip, and a button group. The signal amplifier, storage chip, and button group are respectively connected to the Bluetooth communication module. The button group includes at least volume adjustment buttons and mode switching buttons.

[0031] The control box 5 and the bone conduction microphone 6 work together to enable the reception of external sounds and the playback of internal music or music from Bluetooth devices via bone conduction.

[0032] Taking the pressurization process of personnel entering the transition room of a pressurized building as an example, during pressurization, the air pressure in the transition room gradually increases. Therefore, under the action of the positive pressure gradient between the inside and outside of the tympanic membrane, the gas flows from the transition room through the external auditory canal to the outside of the tympanic membrane, and from the transition room through the Eustachian tube to the inside of the tympanic membrane. During the flow, the airflow is lifted by the ball valve 4.2 under the action of the positive pressure gradient on the outside of the tympanic membrane in the transition room, and the airflow enters the external auditory canal, releasing ear pressure; when the ear pressure reaches equilibrium, the ball valve 4.2 falls back under the action of gravity.

[0033] The over-ear pressure-balanced headphones provided by this utility model can automatically adjust the ear pressure balance through the ear pressure equalization device 4 when the ambient pressure increases or decreases, reducing the impact of outdoor pressure changes on the eardrum. Users can also adjust the external auditory canal pressure value through the manual ventilation valve switch 4.3, allowing the eardrum to gradually adapt to the outdoor pressure and avoiding middle ear barotrauma. At the same time, the use of the over-ear pressure-balanced headphones does not affect the user's ability to receive external sounds, and music can still be played through the headphones.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
