Abstract

The utility model relates to a new-type earplug type loudspeaker which can be normally used by at least one person simultaneously. On the basis that the earplug type loudspeaker is composed of a conducting wire (2) whose two ends are respectively electrically connected with a stereophonic plug (1) and an earplug type loudspeaker (5), more than one pair of earplug type loudspeakers (12, 13), (14, 15), (16, 17), etc. are also electrically connected. The earplug type loudspeakers with the same sound channel are connected in parallel, wherein, when one pair of earplug type loudspeaker is electrically connected, the new-type earplug type loudspeaker can be used by two persons at most; when two pairs are connected, the new-type earplug type loudspeaker can be used by three persons at most; when three pairs are electrically connected, the new-type earplug type loudspeaker can be used by four persons at most, etc.

Description

New earplug formula loud speaker

The utility model relates to a kind of in-ear loudspeaker, especially can not only normally use for a people, and can be for the above normal simultaneously in-ear loudspeaker of using of two people.

At present, known in-ear loudspeaker is to be electrically connected with the in-ear loudspeaker of left and right acoustic channels respectively by lead by stereo plug, stereo plug is inserted the message output stereo jack of eight playback systems, the left and right acoustic channels in-ear loudspeaker is filled in eight respectively surely puts in the auricle of the left and right sides, allow playback system normally export message, just can hear the stereo sound of output, but, in real life, lovers, friend, often run in living or studying between the classmates etc. and all think normally to hear the message of certain playback system output more than two people and do not wish other people therefore affected situation, common in-ear loudspeaker can not satisfy this common demand because only contain a pair of earplug loud speaker.

The purpose of this utility model provides a kind of in-ear loudspeaker, and it can not only normally use for a people, and can be for above normal simultaneously use of two people.

The purpose of this utility model is achieved in that stereo plug is electrically connected with in-ear loudspeaker more than two pairs by lead, and, by the in-ear loudspeaker parallel connection of lead or stereo plug stereo jack or other arrangements of electric connections with sound channel.Because new earplug formula loud speaker is made of the in-ear loudspeaker more than two pairs, the audio signals of playback system output can be simultaneously equably defeated eight each to in-ear loudspeaker and convert sound to, so can be for above normal simultaneously use of two people, and when only using wherein a pair of in-ear loudspeaker, certainly also can normally use, thereby realize the purpose of this utility model for a people.

Owing to the employing such scheme, can be for above normal use of a people, simple in structure, production and use are easily.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, Fig. 2, Fig. 3 are respectively to being the outside drawing that circuit theory diagrams of the present utility model and first and second embodiment supply to use below two people somatotype.

Among the figure, 1,9 is stereo plug, and 8 is stereo jack, and 2,7,10 are lead, and 3,4,11 are the reinforcing cushion rubber, 5,6,12,13,14,15, and 16,17 are in-ear loudspeaker.

In Fig. 1, an end of lead (2) is electrically connected with stereo plug (1), the other end and many to in-ear loudspeaker (5,6), (12,13), (14,15), (16,17) ... be electrically connected; And in-ear loudspeaker parallel connection with sound channel.

In embodiment illustrated in fig. 2, an end of lead (2) is electrically connected with stereo plug (1), and the other end and a pair of in-ear loudspeaker (5,6) are electrically connected; One end of lead (7) is electrically connected with lead (2), and the other end is connected with stereo jack (8); One end of lead (10) is electrically connected with stereo plug (9), and the other end and a pair of in-ear loudspeaker (12,13) are electrically connected; When stereo plug (9) inserts stereo jack (8), in-ear loudspeaker (5) is distinguished in parallel with (12), (6) with (13), can use this moment for two people are normal simultaneously, and when stereo plug (9) does not insert stereo jack (8), two pairs of in-ear loudspeaker (5,6), (12,13) can be for using respectively.

In the embodiment shown in fig. 3, an end of lead (2) is electrically connected with stereo plug (1); The other end and a pair of in-ear loudspeaker (5,6) be electrically connected, one end of lead (10) is electrically connected with lead (2), the other end and another are to in-ear loudspeaker (12,13) be electrically connected, and in-ear loudspeaker (5) and (12), (6) are in parallel respectively with (13), this moment can be for the normally use of two people while, when only listening wherein a pair of in-ear loudspeaker, also can normally use for a people.

Among above-mentioned two embodiment, lead (2) branch road junction and lead (2), the crotch of (10) are put respectively and reinforced cushion rubber (3,4,11), and be firm to guarantee local electrical connection.Dotted line is represented the omission of conductor length among Fig. 2, Fig. 3.
