Embodiment 1
[0028] Such as figure 1 and figure 2 As shown, the earphone with speaker function according to the present invention is mainly composed of a headband 4, two earmuffs 2 and a lead wire 1 with a plug 11: each earmuff 2 is connected to the headband 4 through a connecting piece 41. Both ends, and each earmuff 2 has a built-in speaker 3; the lead wire 1 is electrically connected to the speaker 3, the plug 11 on one end is a USB plug, and a package box 5 is arranged on the line body, and the package box is sequentially A USB audio conversion interface 7, a switch 8, a BASS (bass output) jack 9 (BASS output connector) and an audio power amplifier 6 are provided.
[0029] Such as figure 2 and image 3 As shown, each earmuff includes a horn unit 3 and a shell 2 with a curved inner surface, and the horn unit 3 is placed at the front opening of the shell 2 . The rear end of the speaker unit 3 and the casing 2 form a chamber 22 with a large accommodation space. The housing 2 also i...
Embodiment 2
[0036] Such as Figure 6a , Figure 6b , Figure 6c and Figure 6d As shown, the difference between this embodiment and Embodiment 1 is that the connecting piece 41 between the earmuff 2 and the headband 4 is specifically a two-cylinder joint connection structure, through which the earmuff can be moved relative to the headband. The two-dimensional and three-dimensional rotation can meet different usage requirements, and the space size of the present invention can be further reduced when not in use, so as to achieve the purpose of being convenient for storage and carrying.
[0037] In addition, the connecting member may also be a combined connecting structure of a cylindrical joint and a spherical joint, and these connecting mechanisms are known technologies, and will not be described in detail here.
Embodiment 3
[0039] Such as Figure 7 As shown, the earphone with speaker function described in this embodiment is mainly composed of a headband 4, two earmuffs 2 and a lead wire 1 with a plug 11: each earmuff 2 is connected to the headband 4 through a connecting piece 41 and each earmuff 2 has a built-in speaker 3; the lead wire 1 is electrically connected to the speaker 3, and the plug 11 on one end is a 3.5mm audio plug, and a wrapping box 5 is arranged on the line body, wrapping In the box, switch 8, BASS (bass output) jack and audio power amplifier 6 are arranged successively, and 3.5mm plug, switch 8, audio power amplifier 6 and loudspeaker 3 form the working circuit part of the present invention, and this working circuit principle is as follows Figure 8a and Figure 8b As shown, the audio power amplifier 6 in the figure needs to be powered by a power supply circuit (not shown in the figure). The principle of switching between the functions of the earphone and the sound box in the...
