Description
Technical Field
[0001] The utility model relates to the technical field of decoding headphone amplifiers, in particular to a decoding headphone amplifier with light display. Background Art
[0002] Due to their limited size and form factor, headphone amplifiers (mini-tails) often lack the space for aesthetically pleasing lighting effects that integrate seamlessly with the overall design. Existing headphone amplifiers typically utilize separate light guides within the circuit board for light transmission. Furthermore, with the increasing functionality of current headphone amplifiers, requiring more electronic components, conserving the limited space within the amplifier's PCBA becomes a crucial technical challenge. In light of this, those skilled in the art have designed a headphone amplifier with a light display. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a decoding headphone amplifier with light display, thereby improving the utilization rate of the internal space of the decoding headphone amplifier.
[0004] The technical solution of the present utility model is: a decoding headphone amplifier with light display, comprising an headphone amplifier module, a connector and an headphone amplifier transmission line arranged between the headphone amplifier module and the connector, the headphone amplifier module comprising an external shell, a control panel, an indicator light and a tail plug, the indicator light being connected to both end faces of the control panel, the control panel being arranged in the external shell, the tail plug being covered at the connection between the headphone amplifier transmission line and the control panel, the tail plug comprising a sleeve portion and an installation portion, the installation portion being covered and arranged on the headphone amplifier transmission line, the sleeve portion being covered outside the control panel and arranged in the external shell, the sleeve portion being made of transparent material, and the end face of the sleeve portion being exposed to the external shell.
[0005] It can be seen from the above scheme that the indicator light is connected to the front and back sides of the control board. When the indicator light is on, the ring light display effect of the decoding headphone amplifier is realized through the light-transmitting shape of the end face of the sleeve part. The mounting part is used to protect the connection between the headphone amplifier transmission line and the headphone amplifier module. The utility model realizes the protection and light transmission functions through the tail plug, effectively saving the use of space inside the decoding headphone amplifier. More functional components can be added in the saved space, thereby improving the utilization rate of the internal space of the decoding headphone amplifier and contributing to adding more functions to the decoding headphone amplifier in a limited space.
[0006] The control board includes a connecting portion and a circuit board mounted on the end face of the connecting portion. The connecting portion is coaxial with the outer housing, the width of the circuit board matches the diameter of the connecting portion, and the connecting portion is provided with a retaining ring groove that matches the sleeve portion. Thus, the connecting portion facilitates the assembly of the circuit board within the outer housing, and the retaining ring groove is used to limit the position of the end of the tail plug wrapped on the control board.
[0007] The outer shell is cylindrical and contains a first cavity adapted to the connecting portion and a second cavity adapted to the sleeve portion. The diameter of the first cavity is smaller than the diameter of the second cavity. Therefore, the diameter of the first cavity is adapted to the diameter of the connecting portion, and the second cavity is used to limit the sleeve portion.
[0008] The connector is a Type-C interface. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0015] like Figures 1 to 5As shown, the utility model is a decoding headphone amplifier with light display, comprising an headphone amplifier module, a connector 10 and an headphone amplifier transmission line 20 arranged between the headphone amplifier module and the connector 10, the connector 10 is a Type-C interface, the headphone amplifier module comprises an external shell 1, a control board 2, an indicator light 3 and a tail plug 4, the material of the external shell 1 is not limited to metal or plastic (it can be a hard material with protective properties), the indicator light 3 is connected to the two end faces of the control board 2, the control board 2 is arranged in the external shell 1, the tail plug 4 is covered at the connection between the headphone amplifier transmission line 20 and the control board 2, the tail plug 4 includes a sleeve portion 41 and an installation portion 42, the installation portion 42 is covered and arranged on the headphone amplifier transmission line 20, the sleeve portion 41 is covered on the outside of the control board 2 and is arranged in the external shell 1, the sleeve portion 41 is made of transparent material, and the end face of the sleeve portion 41 is exposed to the external shell 1.
[0016] In this embodiment, the tail plug 4 is a cylindrical, two-color piece. The diameter of the sleeve portion 41 is larger than that of the mounting portion 42. The sleeve portion 41 is made of a transparent, light-transmitting material. The headphone amplifier transmission cable 20 is arranged as a braided rope with a braided outer sheath, which is less prone to damage and has a longer service life. The indicator light 3 is electrically connected to the circuit board 22. When the decoder headphone amplifier is in use, the indicator light 3 illuminates, and light is transmitted through the transparent sleeve portion 41, thereby displaying a ring-shaped light ring effect when in use.
[0017] In another embodiment, the display light 3 further includes a control circuit including a light emitting diode. When processing sound sources with different sound sampling rates, the display light 3 will emit light of different colors, thereby making it easier for the user to identify the sampling rate of the sound source being played.
[0018] The control board 2 includes a connecting portion 21 and a circuit board 22 disposed on the end face of the connecting portion 21. The connecting portion 21 is coaxially disposed with the external housing 1. The width of the circuit board 22 matches the diameter of the connecting portion 21. The connecting portion 21 is provided with a retaining ring groove 23 that matches the sleeve portion 41. The indicator light 5 is connected to the end of the surface of the circuit board 22, and the indicator light 5 is close to the end face of the sleeve portion 41. In this embodiment, the indicator lights 3 are arranged in diagonal pairs or multiple lights, connected to the end of the surface of the circuit board 22, and the indicator lights 3 are disposed close to the end face of the sleeve portion 41. This saves space for a separate light-guiding component inside the circuit board 22 for light transmission. The display light 3 is placed at the end of the circuit board 22, close to the position where the wire is soldered to the circuit board 22, reducing the corresponding need to reserve a separate light-transmitting component on the circuit board 22 for the avoidance space.
[0019] The outer shell 1 is cylindrical and is provided with a first cavity 11 adapted to the connecting portion 21 and a second cavity 12 adapted to the sleeve portion 41 . The diameter of the first cavity 11 is smaller than that of the second cavity 12 .
[0020] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
