[0001] The utility model relates to the technical field of helmet earphones, in particular to a helmet earphone sound generating unit. Background Art
[0002] In the field of audio equipment, helmet headphones, as a special type of headphones, play an important role in many application scenarios, such as motorcycle riding, e-sports games, aviation communications, etc.
[0003] Traditional helmet earphone generators have the following disadvantages:
[0004] (1) The existing sound unit generates airflow directly through the back vents during operation, while the helmet earphone unit is attached to the human ear inside the helmet through ear pads and Velcro snaps with adhesive backing, which causes the airflow holes of the sound unit to be blocked and the airflow to be blocked, resulting in dry sound quality, unclear timbre, poor sound separation, and limited dynamic range.
[0005] (2) The existing helmet earphone sound unit does not have an earphone wire fixing groove, and the glue fixation is not strong enough, which may easily cause the earphone wire to separate from the sound unit or break, resulting in silence. Alternatively, additional fixing holes are added outside the diameter of the helmet earphone sound unit to buckle rivets on the earphone wire to force it into place. The disadvantage is that the material cost and labor cost are increased. Utility Model Content
[0006] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a helmet earphone sound unit with smooth airflow and low labor cost.

[0010] Furthermore, the PCB is respectively connected to the voice coil and the magnet through lines.
[0011] Furthermore, the air guide groove cover is snap-connected to the basin frame.
[0012] The advantages of the present utility model compared with the existing technology are as follows:
[0013] (1) In the present utility model, a groove is designed on the back of the speaker unit chassis, and the air vent holes on the side are combined with the air guide groove cover to form an air guide groove. Then, the air flows through the air vent holes on the side, so that after the assembled product of the speaker unit and the ear pad with the back glue magic tape mother and son buckles is attached to the human ear position inside the helmet, the air flows through the air vent holes on the side of the air guide groove, improving the poor state of sound quality, timbre, etc. caused by the blockage of the air vent holes on the back of the original speaker unit, making the sound quality of the helmet earphone no longer dry, with full timbre, good sound separation, balanced timbre and high reduction degree, truly and effectively improving and enhancing the pleasant listening experience of users.
[0014] (2) In the present utility model, a headphone wire card slot is designed at the port of the PCB board. After the headphone wire is clamped, it is directly fixed by gluing. After the glue is fixed, it effectively improves the adverse factors of easy detachment and disconnection of the headphone wire and the speaker unit caused by the absence of a card slot, or fixed holes are added outside the diameter of the speaker unit and rivets are used to forcibly clamp. The design of the card slot of the present speaker unit effectively increases the service life of the helmet earphone product, achieving the effect of cost reduction and efficiency improvement.

[0019] The following further illustrates the detailed embodiments of the present utility model with reference to the drawings. The same components are denoted by the same reference numerals.
[0020] It should be noted that the terms "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component.
[0021] In order to make the content of the present utility model easier to be clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.
[0022] As Figures 1 to 3 shown, a helmet headphone sound generating unit includes a front cover 1. One side of the front cover 1 is connected with a speaker frame 2. The inner side of the speaker frame 2 is connected with a voice coil 3. The outer side of the voice coil 3 is connected with a diaphragm 4. One side of the speaker frame 2 away from the diaphragm 4 is connected with a tuning mesh cloth 5. A PCB 6 is connected to the speaker frame 2. A headphone wire card slot 11 is provided at the port of the PCB 6. The headphone wire card slot 11 designed at the port of the PCB 6 directly fixes the headphone wire by dispensing glue after the headphone wire is stuck. After the glue is fixed, it effectively improves the adverse factors such as the easy detachment and disconnection of the headphone wire from the sound generating unit caused by the absence of a card slot, or adding fixing holes outside the diameter of the sound generating unit and forcibly clamping with rivets. The design of the card slot of this sound generating unit effectively increases the service life of the helmet headphone product and achieves the effect of cost reduction and efficiency improvement.
[0023] A gas guide groove cover 9 is provided on the outer side of the speaker frame 2. The gas guide groove cover 9 is snap-connected to the speaker frame 2. The groove designed on the back of the speaker frame of the sound generating unit and the side ventilation holes form a gas guide groove after being combined with the gas guide groove cover 9, and then the air flows through the side ventilation holes, so that after the sound generating unit is assembled with the ear pad and the back glue magic tape mother and son buckle and attached to the human ear position inside the helmet, the air flows through the side ventilation holes of the gas guide groove, improving the poor state of sound quality, timbre, etc. caused by the blockage of the ventilation holes on the back of the original sound generating unit, making the sound quality of the helmet headphone no longer dry, the timbre full, the sound separation good, the timbre balanced and the reduction degree high, and truly and effectively improving and enhancing the pleasant listening experience of the user.
[0024] A pole piece 7 is provided on the inner side of the speaker frame 2. A magnet 8 is provided on one side of the pole piece 7. The magnet 8 is located outside the pole piece 7. A yoke 10 is connected to one side of the magnet 8. The yoke 10 is connected to the inner side of the speaker frame 2.

The PCB 6 is connected to the voice coil and other electronic components through a cable, while the pole piece 7 and the magnet 8 are precisely installed on the yoke 10 to jointly provide a stable magnetic field environment for the voice coil 3.
[0025] Working principle: The headphone wire clamping groove 11 designed at the PCB6 port directly fixes the headphone wire by dispensing glue after clamping the headphone wire. After the glue is fixed, it effectively improves the adverse factors such as the easy detachment and disconnection of the headphone wire and the sound generating unit due to the absence of a clamping groove, or adds fixing holes outside the diameter of the sound generating unit and forcibly clamps them with rivets. The design of the clamping groove of this sound generating unit effectively increases the service life of the helmet headphone product, achieving the effect of cost reduction and efficiency increase. The groove designed on the back of the sound generating unit basin frame and the side ventilation holes and air guide groove cover 9 form an air guide groove after combination, and then the air flows through the side ventilation holes, so that the assembled finished product of the sound generating unit and the ear pad with back glue magic tape is attached to the human ear inside the helmet. By flowing the air through the side ventilation holes of the air guide groove, it improves the poor state of sound quality, timbre, etc. caused by the blockage of the ventilation holes on the back of the original sound generating unit, making the sound quality of the helmet headphone no longer dry, the timbre full, the sound separation good, the timbre balanced and the reduction degree high, and truly and effectively improving and enhancing the pleasant listening experience of the user.
