Headset with function of loudspeaker box

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.

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.
