Description

  The present invention relates to headphones (including earphones), more specifically, a plurality of sound source devices that are simultaneously connected to each other, and audio information and music of different contents obtained from each sound source device are arbitrarily selected and combined for listening simultaneously It relates to headphones that can be used.

  Headphones including earphones are devices that convert an electrical signal input from an external sound source device into a sound signal such as audio information or music, and press the ear pinna or the ear canal for listening to the external sound source. A plug that has a speaker unit that converts the electrical signal output from the device into an audio signal and propagates it as air vibration. One end is connected to the terminal of the speaker unit in the main unit and the other end is detachably connected to an external sound source device. It has a connection cord with connectors such as jacks and jacks.

  In the old days, headphones were developed and used to listen to weak sound signals provided by low-performance wireless communication devices and radio receivers while blocking the influence of external sound. As a result of the evaluation of the characteristics that enable personal listening without any hesitation to suppress or block the effects of sound signal propagation (so-called sound leakage) and external sound, conversion of electrical signals into sound signals in various sound source devices Even after the ability of amplification and propagation has improved dramatically, the use of external speakers has no longer hindered its use, and its use has expanded greatly, and the widespread use and penetration of various portable small-sized sound source devices—particularly represented by iPod (registered trademark) Dramatic sound quality improvement and capacity increase in digital audio players and digital still image playback equipment for movies, and daily recording of various types of audio information with digital voice recorders Use - the result, listening use of the sound source device in accordance with the headphones regardless of the indoor outdoor may be said that has been established in the remarkable proceed already everyday life.

  In this way, headphones have seen widespread use today due to the sound insulation that suppresses the influence of external sound and sound leakage to the outside, but conversely, one problem caused by this characteristic was pointed out and solved There is also a need to develop and provide headphones.

  That is, as shown in FIG. 5, in the conventional headphones, one-to-one correspondence with an external sound source device is an absolute premise, and the housing portion 15 in the main body 11 of the headphones 1 that is used while being pressed against the auricle or the ear canal opening is used. Only one or a set of speaker units 13 that should correspond to a single external sound source device is provided, and corresponds to the speaker unit 13 through a single connection cord 14 having connectors such as the jack 2. Connected to a single external sound source device, and is configured to listen to audio information and music provided by the sound source device. Of course, only one sound source device can be listened to with one headphone. You cannot listen to different types of audio information and music provided by the same headphones simultaneously.

  However, a wide variety of sound source devices are carried on a daily basis due to the small size and light weight, and nowadays, for example, a voice recorder can store and collect a large amount of various kinds of audio information and music by a dramatic increase in capacity due to digitalization. There is never a need to listen to the lecture content recorded in, or to listen to the audio information of the foreign language course received through the FM transmitter or stored in the audio player in any combination with the favorite music stored and accumulated in other audio players. Not a few.

  Of course, the one-to-one correspondence between the external sound source device and the speaker unit is not unique to headphones but is common to speakers in general, but a speaker that amplifies and propagates an audio signal to an open space can be used with multiple different sound source devices. By operating multiple sets of separately connected speakers, you can listen to all the different audio information and music of each speaker simultaneously, but no matter how many headphones with high sound insulation, you can install multiple headphones at the same time. It is not possible to listen to different audio information and music from different sound source devices at the same time, and even if the connectors of the connection cord terminal are branched, it is easy to switch between multiple sound source devices and respond to the requested simultaneous listening It is not possible.

  In addition, if a high-function digital editing device is used, it is possible to simultaneously input different audio information and music from multiple sound source devices to the editing device and output them immediately to a single headphone. Operation is not easy for general sound source equipment users, and the request for simultaneous listening is premised on easy and simple operation with a popular external sound source device that is compact and lightweight and highly portable. Unfortunately, this kind of digital editing equipment, which relies heavily on sophisticated and complex operations on the output equipment side, cannot meet the demand for simultaneous listening.

  Furthermore, by using relatively simple editing software, it is possible to pre-edit by combining or overlapping different audio information and music of multiple sound source devices with a personal computer, but this is one-to-one correspondence between sound source devices and headphones. In addition to the use, the pre-editing process is not only cumbersome, but there is also a desire to listen at the same time by selecting and combining different audio information and music of multiple sound source devices according to the situation and mood at the time of listening At the time of listening, the sound information of any one of the sound source devices, the volume of the music, etc. can be increased / decreased or stopped or restarted independently of other sound source devices.

  In the past, it was equipped with a locking means such as a headband and a large-diameter headphone that covered and used the entire auricle and was equipped with a headphone and an earplug that was inserted into the ear canal, and the main body was held at the locking position of the ear canal opening. The small-diameter type that presses down is sometimes called an earphone, but nowadays it is not equipped with a headband and is hooked to the auricle with a hook, so called a small-diameter headphone, or an auricular cartilage process without an earplug. Many so-called earphones that press the main body against the opening of the ear canal by being locked are provided and the clear boundary between them is lost. As a result, all of these listening devices are collectively referred to as headphones. . This terminology is also used in this specification, and the term “headphone” used in this specification includes all of so-called headphones and earphones.

The headphones which can be selected and combined and listened simultaneously are realized.

  FIG. 1 shows an embodiment of a headphone according to the present invention, and FIGS. 3 and 4 show an embodiment of the embodiment. In the illustrated embodiment, an ear plug 12 is inserted into the ear canal to listen. It is a so-called earphone type headphone to be used, which is a stereo type or high fidelity type headphone having a pair of main body portions for right and left ears.

In the headphone 1 according to the present embodiment, in order to convert an electrical signal input by connecting a plurality of different external sound source devices to a hollow housing portion 15 formed inside the main body 11 into an audible audio signal. The first speaker unit 13a and the second speaker unit 13b of the dynamic type are fitted in substantially parallel positions with an angle inclined slightly toward the earplug direction, and each of the speaker units 13a and 13b is fitted. One end of the first connection cord 14a and the second connection cord 14b for connecting each of the speaker units 13a and 13b to a different external sound source device to be individually supported is connected and fixed to the connection terminal. External sound source devices are provided at the open ends of the connection cords 14a and 14b arranged to extend outside. There are provided a first connection jack 2a and a second connection jack 2b which are inserted into and connected to each other. (See Figure 1)

  As shown in FIGS. 3 and 4, the first speaker unit 13a and the second speaker unit 13b fitted in the main body 11 of the pair of left and right headphones 1 and a plurality of different external sound source devices (the first external sound source device 4a and the first sound source device 4). 2 The first connection cord 14a and the second connection cord 14b for connecting the external sound source devices 4b) separately are open ends provided with a first connection jack 2a and a second connection jack 2b which are connectors for connection to the external sound source device. On the part side, each of the two parts is branched into one and covered in parallel at an appropriate position in the middle part direction, but two sets of the first speaker unit 13a and the second speaker unit fitted in the pair of left and right main bodies 11 are provided. In order to connect and fix each terminal portion 13b, two first connecting cords 14a and two second connecting cords 14b are provided at appropriate positions in the direction of the headphone 1 main body 11. The other end of each of the pair of first connection cord 14a and second connection cord 14b is connected to the terminal portions of the first speaker unit 13a and the second speaker unit that are fitted in the left ear main body 11. Connect the other end of each of the other pair of the first connection cord 14a and the second connection cord 14b to the terminal portions of the first speaker unit 13a and the second speaker unit in the main body 11 for the right ear. ing.

  Further, in the embodiment shown in FIG. 3 and FIG. 4, an intermediate portion between the first connection cord 14a and the second connection cord 14b for connecting the external sound source devices 4a and 4b and the two sets of speaker units 13a and 13b as appropriate. A volume controller 3 is provided at a position, and the first volume 3a and the second volume 3b having an adjustment dial are connected to the connection cords 14a and 14b, respectively. (In the present embodiment, at the interposition position of the volume controller 3, the first connection cord 14a and the second connection cord 14b, which are one each on the open end side, are branched into two each. )

  Since the headphones according to the present embodiment have the above-described configuration and are used as in the illustrated embodiment, different electric signals output from the two different external sound source devices 4a and 4b correspond to each other. Since the different speaker units 13a and 13b connected in this way are converted into audio signals separately, it is possible to arbitrarily connect one headphone 1 having a pair of left and right main bodies 11 fitted with the speaker units 13a and 13b. It is possible to listen and enjoy two types of differently selected audio information and music that are selected and combined at the same time.

  Further, in the headphones according to the present embodiment, the electric signals output via the connection cords are separately provided at intermediate positions between the two types of connection cords 14a and 14b connecting the external sound source devices 4a and 4b and the speaker units 13a and 13b. Volumes 3a and 3b that can be adjusted independently to increase or decrease the volume of the audio signal obtained on each speaker unit 13a and 13b are provided. For example, digitally behind the audio information of a lecture recorded in a voice recorder If you want to concentrate on the important audio information part of the lecture while listening to the music of the audio player and listening to it at the same time, you can lower the volume of the music to the lowest level or increase the volume of the lecture part. Because it is possible to use the system at any time, the request for simultaneous listening is truly suitable.

  In this embodiment, as the speaker units 13a and 13b fitted in the housing portion 15 formed in the main body 11 of the headphone 1, a permanent magnet is arranged in the hollow portion of the voice coil to which the diaphragm is attached. Although a dynamic type speaker unit that applies an electric signal to a voice coil in a magnetic field to vibrate is used, it is needless to say that this is merely a matter of explanation and can be implemented using any type of speaker unit. FIG. 2 shows an example in which another type of speaker unit is used. Crystal type speaker units 13a and 13b which are made of a vibration thin film by attaching a metal plate to piezoelectric ceramic are used, and a dynamic type speaker unit is used. Since a thinner and smaller one can be used, the first speaker unit 13a, which is suitable for audio information reproduction, is arranged at the center front position of the relatively large second speaker unit 13b, which is suitable for music reproduction. It is fitted.

  Further, in this embodiment, the volume controller 3 is stopped at an intermediate position between the connection cords 14a and 14b connecting the external sound source devices 4a and 4b and the speaker units 13a and 13b, but each connection cord 14a such as an on / off switch is used. It is also optional to provide other adjustment operation means that function independently for each 14b, and the relationship is within the scope disclosed in the present invention.

  Furthermore, in the present embodiment, two types of speaker units 13a and 13b for simultaneously listening to different audio information and music pieces are used and correspond to two external sound source devices. However, this number has no particular meaning. Technically, it is possible to provide three or more types of speaker units and support three or more external sound source devices. Whether or not there are realistic demands and advantages is not excluded. .
