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

[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...

Abstract

The invention discloses a headset with the function of the loudspeaker box, at least comprising two earmuffs, a lead, an audio-frequency power amplifier, a shift switch and transmission lines. Each of the two earmuffs is internally provided with a loudspeaker; the lead is provided with a plug and is electrically connected with the two loudspeakers; the audio-frequency power amplifier is arranged on the lead and is electrically connected between the plug of the lead and the two loudspeakers; the shift switch is used for shifting different audio-frequency output power signals to the two loudspeakers so as to shift the function of headset or the function of the loudspeaker box; the inner cavity of each of the two earmuffs is provided with one transmission line for generating the helmholtz resonance; and the outlet holes of the transmission lines are arranged on the shells of the two earmuffs so as to effectively strength the low-frequency response of the loudspeaker box and the headset. Adopting the structure, the headset with the function of the loudspeaker box has simple structural design and light weight and is easy to operate and convenient to carry. The function of the headset and the function of the loudspeaker box can be shifted immediately, thus the cost spent in buying the loudspeaker box by the consumer is saved. The low-frequency response of the headset with the function of the loudspeaker box can be effectively strengthened.

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 headphones 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 speakers. At...
