[0033] like Figures 1 to 5 As shown, this embodiment provides a hybrid dual-unit earphone, comprising:

[0034] An earphone housing 100, wherein a built-in cavity 120 is disposed in the earphone housing 100, a sound outlet 110 communicating with the built-in cavity 120 is opened on the earphone housing 100, an independent sound guide cavity 131 is disposed in the built-in cavity 120, and the opening of the sound guide cavity 131 faces the sound outlet 110;

[0035] The dynamic unit assembly includes a dynamic speaker 200 disposed in the internal cavity 120, and the sound output direction of the dynamic speaker 200 is arranged toward the sound outlet 110;

[0036] The high-frequency unit component includes a high-frequency speaker 300 disposed in the sound guide cavity 131 , and the sound output direction of the high-frequency speaker 300 is disposed toward the sound outlet 110 .

[0037] In this embodiment, a built-in cavity 120 and a separate sound guide cavity 131 are provided in the earphone shell 100, and the dynamic speaker 200 is provided in the built-in cavity 120 and its sound output direction is arranged toward the sound outlet 110, and is responsible for the audio output of the open mid- and low-frequency parts. The high-frequency speaker 300 is provided in the sound guide cavity 131 and its sound output direction is arranged toward the sound outlet 110, and is responsible for the output of the high-frequency and ultra-high-frequency parts, so that the sound quality output from the earphone sound outlet 110 can take into account the output of the high-frequency and low-frequency bands, thereby effectively improving the performance and quality of the output audio and improving the user experience.

[0038] Furthermore, the dynamic speaker 200 and the high-frequency speaker 300 are respectively arranged in two chambers, which can avoid mutual interference between the output high-frequency audio and the low-frequency audio to a certain extent, which is beneficial to improving sound separation, ensuring the output sound quality performance and quality, and improving the user experience.

[0039] In actual operation, the high-frequency speaker 300 uses a MEMS speaker. The MEMS speaker is small in size and thin in thickness. It can be easily set in the sound guide cavity 131 of directional sound transmission to output audio toward the sound outlet 110, which is beneficial to reduce the overall size, height and thickness of the headset, and avoid problems such as affecting the appearance of the headset or affecting wearing.

[0040] In actual applications, open-back headphones using only dynamic units begin to attenuate at 6-7kHz. This embodiment greatly expands the bandwidth by combining the dynamic speaker 200 with the MEMS speaker on open-back headphones. The high-frequency verification can reach 30kHz, and the high-frequency details are rich and delicate.

[0041] In one embodiment, a partition 130 is provided in the earphone housing 100, and the partition 130 is bent on one side away from the built-in cavity 120 to form a sound guide cavity 131. The partition 130 is provided with a through hole 132 connecting the built-in cavity 120 and the sound outlet 110, so that the dynamic speaker 200 arranged in the built-in cavity 120 can output audio through the through hole 132.

[0042] In one of the embodiments, the dynamic speaker 200 and the high-frequency speaker 300 are non-coaxially arranged, and the sound guide cavity 131 and the through hole 132 are arranged side by side on the partition 130, that is, the direction of audio output of the dynamic speaker 200 through the through hole 132 and the direction of audio output of the high-frequency speaker 300 in the sound guide cavity 131 are not on the same axis, so that the mid- and low-frequency parts output by the dynamic speaker 200 and the high-frequency part output by the high-frequency speaker 300 do not interfere with each other, which can effectively improve the sound separation, help to ensure the output sound quality performance and quality, and improve the user experience.

[0043] In one embodiment, a sound outlet 110 is provided with a sound outlet tuning net 111 at one end away from the partition 130, and the sound outlet direction of the dynamic speaker 200 is arranged toward the sound outlet tuning net 111. The audio output of the dynamic speaker 200 is adjusted by the sound outlet tuning net 111 to avoid turbidity of the output audio. Specifically, according to different processing and user needs, by adjusting the mesh size and shape of the sound outlet tuning net 111, the frequency of the audio can be changed to a certain extent, thereby achieving the purpose of enhancing certain frequency bands or reducing other frequency bands, and improving the pertinence and adaptability of the overall device.

[0044] In one embodiment, a front tuning net 310 is provided at one end of the high frequency speaker 300 facing the sound outlet 110, and a rear tuning net 320 is provided at one end of the high frequency speaker 300 facing the internal cavity 120. In this embodiment, since the high frequency speaker 300 and the dynamic speaker 200 are separately provided, the high frequency speaker 300 can be adjusted separately, such as adjusting the polarity of the high frequency speaker 300, the damping of the front tuning net 310 and the rear tuning net 320, and the amplification factor of the power amplifier, without the need for a frequency division circuit, and can be well connected with the dynamic speaker 200, thereby obtaining balanced and extended high frequency sound quality, and the operation is simple and convenient.

[0045] In one of the embodiments, the sound outlet 110 is further provided with a protective net 140, which is arranged on the side of the sound outlet tuning net 111 and the front tuning net 310 away from the built-in cavity 120, and is used to separate the sound outlet tuning net 111 from the outside world, so as to protect the sound outlet tuning net 111. At the same time, through the protective net 140, the protection of the sound guide cavity 131 and the high-frequency speaker 300 arranged in the sound guide cavity 131 can also be effectively achieved. In actual operation, the protective net 140 is made of metal material. In this embodiment, a steel net is used, which has the advantages of sufficient strength, easy processing, good stability, etc. Of course, in addition to this embodiment, other metal materials such as copper, copper alloy, aluminum alloy and the like can also be used, and such designs all belong to the protection scope of the present utility model.

[0046] In one of the embodiments, a face cover 150 is provided on one end of the built-in cavity 120 away from the sound outlet 110, and the face cover 150 is detachably connected to the earphone housing 100. By removing the face cover 150, the internal components of the earphone housing 100 can be easily isolated from the outside world, and maintenance and other operations on the internal components of the earphone housing 100 can be performed conveniently.

[0047] In one embodiment, the earphone housing 100 is further provided with a plurality of leakage holes 160 connected to the built-in cavity 120, for maintaining the air pressure balance of the built-in cavity 120. When the dynamic speaker 200 plays sound, sound waves are generated, and these sound waves form pressure in the built-in cavity 120, allowing part of the air to flow out through the leakage holes 160, thereby maintaining the air pressure in the built-in cavity 120 stable, avoiding the sound quality being affected by excessive pressure, and also helping to improve the bass effect of the dynamic speaker 200.

[0048] In one embodiment, a plurality of leakage holes 160 are respectively provided with a leakage hole tuning net 170 to more accurately adjust the audio and prevent the audio from becoming turbid. The leakage holes 160 include side leakage holes 161, which are arranged on the side wall of the earphone housing 100. There are two side leakage holes 161, which are respectively arranged on two opposite side walls of the earphone housing 100. The plurality of leakage holes 160 is conducive to ensuring the stability of the air pressure of the built-in cavity 120, thereby improving the sound quality.

[0049] Furthermore, the leakage hole 160 further includes a top leakage hole 162, which is disposed on the face cover 150. Since the face cover 150 faces the side away from the human ear, there is no shielding on the side of the top leakage hole 162 facing the outside world, which facilitates the discharge of the airflow of the built-in cavity 120. In addition, the top leakage hole 162 is away from the human body, and the air temperature on one side of the top leakage hole 162 is relatively low, which facilitates the discharge of the airflow of the built-in cavity 120 through the top leakage hole 162.

[0050] In actual operation, protective nets 140 are set at several leakage holes 160 to protect the leakage hole tuning net 170 and effectively isolate the inside and outside of the earphone shell 100, prevent dust and debris from entering the inside of the earphone shell 100, and protect the components in the earphone shell 100 from damage.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
