In view of the above, in order to solve the above-mentioned deficiencies, the object of the present invention is to provide a head-mounted audio-visual device, which includes a projection lens and an earphone, which can project a larger image. Users can effectively reduce the burden on the eyes while enjoying high-quality audio and video effects.

In order to achieve the above object, the present invention provides a head-mounted projection earphone structure, comprising a headphone set, a control module, a projection module and an audio module; the earphone set is hung by the earphone shell, the earmuff and the earphone head The control module is electrically connected to the projection module and the audio module, and is controlled by the control module; the projection module includes a projection lens, and the projection lens is disposed directly above the earphone head; The audio module includes a speaker disposed in the earmuff; when the image is played, the sound is generated from the speaker, and the projection lens can project the image on the wall.

The improvement of the structure of the head-mounted projection earphone, wherein the control module comprises a processing unit and is electrically connected with a storage unit, a memory card reading slot, and a USB interface; the processing unit integrates functional operation and control of the entire electrical system; The unit and the memory card reading slot provide access to digital data, and the data can be transmitted in both directions through the USB interface.

The improvement of the structure of the head-mounted projection earphone, wherein the control module further comprises a battery unit coupled and provided The processing unit can be charged via the USB port.

The improvement of the structure of the head-mounted projection earphone, wherein the control module further comprises a Bluetooth module.

The improvement of the structure of the head-mounted projection earphone, wherein the control module further comprises an operation interface disposed on the outer surface of the earphone set.

The advantage of the novel head-mounted projection earphone structure is that the integrated earphone and the projection lens have an integrated structure, which is convenient for the user to project the image into a larger picture, in addition to facilitating the opening of the video conference and watching the video, in addition to allowing the user to obtain Better comfort and avoid eye damage caused by small screens.

Figure 3 is a functional block diagram of a preferred embodiment of the present invention.

Figure 4 is a schematic view showing the use of the preferred embodiment of the present invention.

In order to further clarify the technical means and other features of the present invention, the following description of the preferred embodiments and the accompanying drawings is to be understood by the accompanying drawings. Implementation.

First, please refer to FIG. 1 and cooperate with FIG. 2 to show the better structure of the head-mounted projection earphone of the present invention. The embodiment mainly includes an earphone set 10, a projection module 20, an audio module 30, and a control module 40. The earphone set 10 is composed of an earphone shell 11, an earmuff 12 and an earphone head 13 connected to the two earphone shells 11. The main structure of the novel appearance is hangable to the user's head.

As shown in FIG. 1 , in the structural improvement of the above-mentioned head-mounted projection earphone, the control module 40 is disposed in the inner space of each of the earphone shells 11 , and the projection module 20 and the audio module 30 are connected to each other. The control module 40 is electrically connected and operated by its control. The projection module 20 includes a projection lens 21 disposed at a position directly above the headphone jack 13; the audio module 30 includes a speaker 31 disposed in the ear cup 12; when performing a video playback function In addition to being generated from the speaker 31, the projection lens 21 can simultaneously project an image and display it on a simple wall.

Please refer to FIG. 3 , which is a functional block diagram of the present invention. The control module 40 includes a processing unit 41 and is electrically connected to the storage unit 42 , the memory card reading slot 43 , and the USB interface 44 . The processing unit 41 integrates the functional operation and control of the entire electrical system; the storage unit 42 and the memory card reading slot 43 provide access to digital data, and the bidirectional transmission of data can be performed through the USB interface 44. Accordingly, the audio and video data in the storage unit 42 or the memory card 431 can be provided to the projection module 20 and the audio module 30 for playback. Of course, connecting the mobile phone or the computer via the USB interface 44 with the data line 45 can also be used to instantly play the audio and video data with the mobile phone or the computer.

The control module 40 can further include a battery unit 50, a Bluetooth module 60, and an operation interface 70; The battery unit 50 is electrically coupled to the processing unit 41 and provides an operating voltage required for offline operation, and can be charged via the USB interface 44. The Bluetooth module 60 has a wireless data transmission function, so that the earphone can be used in a wireless mode. The operation interface 70 is disposed on the exterior of the earphone set 10, and provides an operation mode of the user other than being controlled by a mobile phone or a computer.
