Problems solved by technology

At present, there is a converter for earphones and speakers on the market. The plugs of the earphones and speakers are plugged into the converter, and the switch between the earphones and the speakers can be realized by operating the switch. In the case of these two devices, speakers and speakers, it still cannot meet people's needs.
[0004] Chinese patent 200620137507.2, a stereo earphone that can be used as a speaker, and 200620157870.0, an external loudspeaker earphone all disclose a headset with the functions of an earphone and a speaker, but all are by setting two sets of speakers on the earphone, namely a One set realizes the headphone function and the other one realizes the speaker function. In this way, the weight of the headphone will inevitably be increased, which will increase the burden on the head when people use it, and lack comfort.

Embodiment 1

[0026] Such as figure 1 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 USB audio conversion interface 7, switch 8 and audio power amplifier 6 are provided, USB plug, USB audio conversion interface 7, switch 8, audio power amplifier 6 and loudspeaker 3 form working circuit part of the present invention, and this working circuit principle is as follows Figure 2a and Figure 2b shown. The principle of switching between the functions of the earphone and the sound box in the present invention will be described below through the principle of the circuit...

Embodiment 2

[0032] Such as Figure 4a , Figure 4b , Figure 4c and Figure 4d 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.

[0033] 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

[0035] Such as Figure 5 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 an RCA audio plug, and a package box 5 is arranged on the wire body, and the package box Inside, switch 8 and audio power amplifier 6 are arranged successively, and RCA 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 6a and Figure 6b 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 present invention wil...

Abstract

The invention relates to an earphone, particularly to an earphone with the sound box function. The earphone at least comprises two earflaps, an audio-frequency power amplifier and a selector switch, wherein each earflap has a built-in loudspeaker and a lead wire with a plug; the lead wire is connected with the loudspeaker in the earflap electrically; the audio-frequency power amplifier is installed on the lead wire and electrically connected between the plug and the two loudspeakers; and the selector switch is used for switching signals with different audio output power to the two loudspeakers. Through the adoption of the above structure, one earphone can realize the immediate switch between the function of the general earphone and the function of the sound box. Furthermore, the earphone has the advantages of simple and light structure, concise design, easy operation, convenient carrying, and saved purchase cost for customers.

Description

technical field [0001] The invention relates to an earphone, in particular to an earphone with the function of a sound box. Background technique [0002] Both earphone speakers and speakers contain speakers, which are sound-generating devices that convert audio signals into sound. The earphones are small and exquisite, have low power and low sound, and are often hung on the ear or worn on the head to stick to the ear hole during use. The speaker is large in size, high in power, loud in sound, and can produce very contagious stereo sound, etc. [0003] With the diversification and improvisation of people's taste needs, the enjoyment of music and other sounds may have different situational requirements according to the improvisational needs, such as listening to headphones for a while, and immediately want to listen to speakers for a while; even the same song, this I want to listen to the first paragraph with headphones, and I want to listen to the next paragraph with speake...
