Abstract
The utility model provides a sound field changeable earphone, comprising an earphone and a sound signal input end which are connected though a conducting wire, which is characterized in that at least one converting switch capable of being used for exchanging the polarities of the sound channel is arranged on the sound field changeable earphone. The sound field changeable earphone has scientific design and reasonable and simple structure, which skillfully applies the converting switch to the existing earphone and makes use of the converting switch arranged on the connecting conducting wire of the earphone to realize the exchange of the polarities of the sound channels of two loudspeakers or microphones and realize that two loudspeakers or microphones output the simultaneous and same-direction sound signal; thereby, the utility model eliminates the pain probably caused by the existing public earphone which outputs the sound signal to different directions and simultaneously attacks eardrums inward or pulls the eardrums outward when being used so as to raise the listening comfort, and the sound field changeable earphone simultaneously raises the resolution of the loudspeakers through changing a sound field.
Description
Technical field
The utility model relates to earphone, especially a kind of sound field convertible earphone.
Technical background
Chinese patent application number is: 01278410.9 discloses a kind of " earphone ", this earphone exists at existing known earphone: during use, two loudspeaker or the loud speaker that constitute earphone have output or opposing output dual mode in opposite directions usually, that is: export inwardly and export outwardly from ear from the ear outside.Because the middle inner ear and the oral cavity of ears are to communicate, form confined space.Therefore, when the earphone message of two ears is exported inwardly, directly during the forward impact ear-drum, the confined space in the left and right sides pressure inner ear and oral cavity and reaching in through the ear-drum start, eardrum is difficult, and sound is unclear and can make people's feels pain.Equally, when the earphone of two ears is outside, then outwards pull, can stimulate ear-drum equally, produce pain because of ear-drum.It is to be equidirectional earphone that a kind of message output of two bodies is provided.Yet the concrete structure of this application and this equidirectional earphone of unexposed formation, and this earphone that is single direction output can not satisfy the needs of being accustomed to existing structure earphone user.
Summary of the invention
The purpose of this utility model be at above-mentioned message with the deficiency that output earphone in side exists, provide a kind of and can satisfy message and export in the same way, can satisfy the sound field convertible earphone of message subtend output again.
The utility model sound field convertible earphone comprises: earphone and message input by lead connects is characterized in that: be provided with one on it at least and can be used for the diverter switch that sound channel polarity is exchanged.
Described message input is the shaft-like plug that is connected conductor wire end.
Described message input is the wireless receiver that is connected conductor wire end.
The utility model sound field convertible earphone design science, rational in infrastructure, simply, it is applied to diverter switch existing earphone dexterously, utilization is arranged on earphone and connects the exchange that diverter switch on the lead realizes two loudspeaker or loudspeaker channel polarity, realize two loudspeaker or loud speaker output message in the same way synchronously, during use, be worn on a message seismic wave of loudspeaker output on picking up the ears piece and can pick up the ears to be passed to ear-drum via this, open in one ear-drum, another ear-drum is opened outward, oral cavity space can not change, thereby eliminate the existing known non-output of message in the same way earphone use in to ear-drum inwardly pincer attack or outwards pull issuable pain simultaneously, the comfort level of listening to raising.Simultaneously by changing the definition that sound field improves loudspeaker.
The concrete structure of the utility model sound field convertible earphone is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is sound field convertible head circuit figure;
Fig. 2 is the structural representation of sound field convertible earphone shown in Figure 1;
Fig. 3 is the another kind of structural representation of sound field convertible earphone shown in Figure 1;
Fig. 4 is another structural representation of sound field convertible earphone shown in Figure 1;
Fig. 5 is another structural representation of sound field convertible earphone shown in Figure 1.
Embodiment
Embodiment 1; Can be clear that from Fig. 1 and Fig. 2 sound field convertible earphone is made up of earphone 1, lead 2, message input 3 and diverter switch 4, described earphone 1 comprises: left horn 11 and right horn 12, left and right sides loudspeaker 11,12 connect message inputs 3 by lead 2, and what diverter switch 4 was arranged on earphone 1 and message input 3 is connected 2 in lead.Described message input 3 is the shaft-like plugs that can be connected with the audio device inserting.
Stir dialling of diverter switch 4 and turn round 41 or dial and turn round the 42 circuit switchings that can realize message input 3 and 1 lead 2 of earphone.When dialling of diverter switch 4 turned round 41, to dial and turn round 42 when being allocated to the right, the message of two loudspeaker 11,12 is exported relatively, and its message effect is identical with known earphone, is allocated to the left side if will dial of turning round in 41,42, can change loudspeaker+,-polarity, realize the output in the same way of two loudspeaker, 11,12 message.
Embodiment 2: can be clear that from Fig. 3 this is another kind of sound field convertible earphone, and its structure and 2 substantially the same manner as Example 1, difference is: diverter switch 4 is installed on the connection lead 21 of side loudspeaker 11.
Embodiment 3: can be clear that from Fig. 4 this is another sound field convertible earphone, its structure and embodiment 2 are also basic identical, and difference is: diverter switch 4 is arranged on the side loudspeaker 11.
Embodiment 4: can be clear that from Fig. 5 this is another sound field convertible earphone, its structure is substantially the same manner as Example 1, and difference is: described message input 3 is wireless receivers, and described diverter switch 4 is arranged on the wireless receiver 32.
