Description

  The present invention relates to a neck-type speaker device in which a speaker is attached to a case that is curved in a substantially inverted U shape so that it can be locked to the neck and shoulders of a user.

  A neck-type speaker device, which is an electronic device attached to a user's neck, has a shape and configuration similar to an overhead type headphone placed on a user's head having a headband. While the headphone has a housing with a speaker unit attached to the user's ear and plays sound, the head-mounted speaker device has a substantially inverted U shape so that it can be locked to the user's neck and shoulders. A speaker that radiates sound waves may be attached to a curved housing.

  The neck-mounted speaker device here is not only a stereo type in which a pair of left and right housings are connected by a headband or the like, but also a monaural type in which the housing is attached only to one ear of the user, or a housing. A so-called headset including a microphone device is included. The neck-type speaker device may include not only a speaker but also a circuit such as an amplifier that amplifies an audio signal or a receiver that wirelessly receives an audio signal, a connection terminal that further connects an earphone or headphones, and the like. . Further, the case of the neck-mounted speaker device not only means a box that houses and attaches the components constituting the neck-mounted speaker device, but also includes a portion that does not have a hollow box structure. . For example, the curved band member that forms the casing may not be a hollow member, but may be a member that causes the wiring member to be along a solid member of a metal material or a resin material.

  For example, the headband can be used as a simple installation type speaker or a headband in which a pair of speakers and ear pads are curved in a substantially inverted U shape so as to be used as a headphone. There is a headphone that includes a speaker rotation mechanism that can rotate in the outer direction of the speaker and that rotates and fixes the speaker inside the headband (Patent Document 1).

  However, since the neck-mounted speaker device is an electronic device in which the part to be worn on the user's body is different from the headphone, the structure that the case should have is different from the case structure of a normal headphone. There is. For example, in an electronic device to be worn on the user's body, a device such as covering the surface of a housing that touches the body with a flexible elastic material is required. Various types of necklace type speaker devices and electronic device casings suitable for the necklace type speaker devices have been proposed.

  For example, the neck-type speaker device is a neck-type speaker that can be necked in a non-contact state with the listener's ear, and has a base portion having a curved portion in contact with the back of the listener's neck, and a sound source A neck-mounted speaker is provided with a speaker unit that is provided with a fixed or variable speaker angle at one or both ends of the base so that the front surface of the speaker faces the inside of the curved portion. Yes (Patent Document 2). This neck hanging type speaker is made of a flexible material, and the base part is made of a flexible material so that the base part can be displaced in an arbitrary shape and can retain the shape after the displacement. One or both of the front ends of the speaker is provided with an adjustment unit that holds the speaker unit rotatably so that the angle of the speaker can be varied so that the front surface of the speaker as a sound source faces the inside of the curved portion. And the like.

  In addition, the neck type speaker device is arranged on the user's torso side with respect to the user's auricle and the auricle side with respect to the center axis of the torso in a state in which the sound device is mounted on the user, and can be used. A parametric speaker that is equipped with multiple ultrasonic transducers that emit modulated ultrasonic waves so as to generate an audible sound, and the emission of ultrasonic waves that are emitted from the parametric speaker while the acoustic device is attached to the user There is a portable acoustic device including an adjustment unit configured to be able to adjust the direction toward the auricle (Patent Document 3). FIG. 10 of Patent Document 3 shows a state in which the user 900 wearing the acoustic device 10D of the fourth embodiment tilts forward. In a neck-mounted speaker device, when the user leans forward, the wearing state changes and becomes unstable, and the direction of sound waves emitted by the speaker deviates from the direction of the user's pinna and moves to the surroundings. There is a risk of increased sound leakage. In the fourth embodiment, the description is made so that inclination correction or direction adjustment is performed by signal processing of a parametric speaker.

  Note that an acoustic device including a microphone or speaker around the neck is described as the prior art (paragraphs 0007-0010, FIG. 14), and an electroacoustic conversion is provided for the purpose of providing an acoustic device that can be stably attached and easily attached and detached. And a plurality of support members provided to support the device, the support members extending in different directions starting from the acoustic transducer, and the support members are at least two points on the back and front of the body An acoustic device comprising a support structure for supporting and fixing at a support point, wherein the electroacoustic transducer is positioned on the front of the chest of the body when the acoustic device is attached to the body. Yes (Patent Document 4). However, the embodiment of the acoustic device disclosed after the means for solving the problem of Patent Document 4 has a configuration that can no longer be called a neck type.

  In the neck-mounted speaker device, the speaker is fixed at a position away from the user's ear, so that the ear is not blocked like a headphone. In this respect, the neck type speaker device is more advantageous than the headphone when the user needs to pay attention to external sound other than the sound reproduced from the speaker. In this respect, the neck-type speaker device is more suitable for use in driving a bicycle than headphones or earphones configured to close the ears. Because it is dangerous to drive a bicycle, it is dangerous to listen to music, etc. at a loud volume that prevents you from hearing audible alarms, emergency vehicle sirens, or traffic sounds or voices necessary for safe driving. This is because it is prohibited.

  However, there is a problem to be solved in order for a user who is a bicycle driver to use the neck speaker device. In many neck-speaker-type speaker devices based on the user's upper body being almost upright, the wearing state may change when the user using the device leans forward as described in FIG. There is. Bicycle drivers often have a forward leaning posture that leans forward more strongly than the upper body stands upright due to the positional relationship between the handle to add hands, the saddle on which the buttock is placed, and the pedal on which the foot is placed. However, there is a problem that the wearing type speaker device is liable to hang from the neck literally, so that the wearing state tends to be unstable.

  In the case of a head-mounted speaker device deviated from a predetermined mounting position, there is a possibility that a predetermined performance in sound reproduction cannot be exhibited. That is, there is a demand for a neck-type speaker device that can be mounted stably and hardly deviates from a predetermined mounting position even when the user's upper body is almost upright or in a forward leaning posture.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention relates to a neck-type speaker device, which is a forward leaning posture in which the upper body of the user is more strongly bent than when standing upright. Even if it is a case, it is intended to provide a neck-type speaker device that constitutes a housing so that it can be stably locked to the neck and shoulders of the user, and exhibits predetermined performance in sound reproduction. is there.

  The neck-mounted speaker device according to the present invention has a substantially inverted U-shaped housing in which the front neck side is opened and the rear neck side is curved so that it can be locked to the neck and shoulders of the user. A neck-mounted speaker device to which at least a speaker is attached, wherein the housing has a rear neck contact member that contacts the user's rear neck, and extends from the rear neck to the lower side along the cervical spine. A spinal column abutting member that abuts on the back spine is attached to the posterior neck abutting member.

  Preferably, in the neck-mounted speaker device of the present invention, the rear neck contact member and the spine contact member of the housing are attached so as to maintain a predetermined angle substantially perpendicular to each other. When used with the shoulder locked, the rear neck contact member and spine contact member will contact the user's rear neck and spine, and the housing will open even if the user takes a forward leaning posture. Suppresses the end side from shaking and moving in the user's chest.

  Preferably, in the necked speaker device of the present invention, the rear neck contact member of the housing attaches the spine contact member via a removable attachment mechanism.

  Preferably, in the necked speaker device according to the present invention, the rear neck contact member of the housing is provided with a spine contact member via an attachment mechanism capable of accommodating a part or all of the interior of the housing. Install.

  Preferably, in the necked speaker device of the present invention, the housing curved in a substantially inverted U shape has a speaker mounting member to which the speaker is mounted on the open end side, and at least the speaker mounting member An elastically deformable member that can be changed by elastic deformation is provided between the rear neck contact member.

  The operation of the present invention will be described below.

  The neck-mounted speaker device according to the present invention has a substantially inverted U-shaped housing in which the front neck side is opened and the rear neck side is curved so that it can be locked to the neck and shoulders of the user. At least a speaker is attached. The housing of the neck-type speaker device has a rear neck abutting member that abuts on the user's rear neck, and is further extended downward from the rear neck along the cervical spine to the spine of the back. The abutting spinal column abutting member is attached to the rear neck abutting member. Accordingly, the spine portion contact member is attached to the rear neck contact member as compared with the conventional necked speaker device having a substantially inverted U-shaped housing, so that the neck portion and the shoulder portion of the user can be stably provided. Can be locked to.

  Here, it is preferable that the rear neck contact member and the spinal column contact member of the housing are attached so as to maintain a predetermined angle substantially orthogonal to each other. In other words, based on the fact that the upper body of the user is almost upright, if the rear neck contact member and the spinal column contact member are attached at an angle close to a predetermined substantially orthogonal angle, the user can move the neck and shoulders. When the cervical abutment member and the vertebral column abutment member are in contact with the user's cervical and vertebral parts, the user's cervical and vertebral column parts follow the user's cervical and spinal column parts. is there.

  In addition, if the spinal column abutting member is attached to the rear neck abutting member of the housing, the open end side of the housing can be swung in the chest of the user even if the user takes a forward leaning posture. Can be suppressed. When the user leans forward, the force acting on the casing causes a pivotal force to swing forward using the rear neck and the rear neck abutting member on which the casing is in contact as a fulcrum. . However, if the spinal column abutting member is attached to the posterior neck abutting member as in the present invention, the spinal column abutting member is attached to the housing even when the user is in a forward leaning posture that strongly bends forward. Since the movement is suppressed, the neck-type speaker device can be stably locked to the neck and shoulders of the user, and can be suitable for use when driving a bicycle.

  In the neck type speaker device, it is preferable that the rear neck contact member of the housing is attached to the spine contact member via a removable attachment mechanism. The rear neck contact member of the housing may be attached to the spine contact member via an attachment mechanism that can accommodate a part or all of the interior of the housing. In other words, it is preferable that a user who is unlikely to use in a forward leaning posture can be simply used as a neck-type speaker device including a casing having no spine contact member. If the spine abutting member can be removed or accommodated, the neck hanging type speaker device has an advantage that the overall size becomes small and thin, so that handling such as carrying is easy.

  The necked speaker device includes a speaker mounting member to which a speaker is mounted on an open end side, and a housing curved in a substantially inverted U shape, and includes at least a speaker mounting member and a rear neck contact member. It is only necessary to have an elastic deformation member that can be changed by elastic deformation. Since the elastically deformable member bends due to elasticity, a neck-mounted speaker device suitable for being deformed and worn along the user's body can be configured. In this way, it is possible to attach the speaker to a position relatively close to the ear of the user who wears it, or to a position in front of the ear and near the scapula of the chest.

  The neck-mounted speaker device according to the present invention has a spinal column abutting member that is attached to the rear neck abutting member of the housing and has a forward leaning posture in which the user is strongly bent forward. Suppresses the movement of the chassis, and the neck speaker system can be stably locked to the neck and shoulders of the user, and it provides the prescribed performance for sound reproduction, so that when driving a bicycle It can be made suitable for use.

It is a figure explaining the neck type speaker apparatus using the electronic device housing | casing by preferable embodiment of this invention. (Example 1) It is a figure explaining the mounting state of the neck type speaker apparatus by preferable embodiment of this invention. (Example 1) It is a figure explaining the mounting state of the neck type speaker apparatus by preferable embodiment of this invention. (Example 1) It is a figure explaining the structure of the electronic device housing | casing of the neck type speaker apparatus by other preferable embodiment of this invention. (Example 2)

  Hereinafter, neck-mounted speaker devices according to preferred embodiments of the present invention will be described, but the present invention is not limited to these embodiments.

  FIGS. 1-3 is a figure explaining the neck type speaker apparatus 1 using the housing | casing 2 which is an electronic device housing | casing by preferable embodiment of this invention. Specifically, FIG. 1 is a perspective view of the neck type speaker device 1, and FIGS. 2 and 3 are diagrams for explaining a mounting state of the neck type speaker device 1. In the following, illustration and description of a part of the structure and internal structure of the neck type speaker device 1 unnecessary for the description of the present invention are omitted.

  As shown in FIGS. 1 and 2, the neck speaker device 1 is an electronic device attached to the neck 5 a and the shoulder 5 c of the user 4, and the speaker 3 that emits sound waves is attached to the housing 2. Thus, the sound reproducing device is arranged at a position away from the ear 5f of the user 4. In the neck-mounted speaker device 1, the speaker 3 is attached to a housing 2 that is curved in a substantially inverted U shape so that it can be locked to the neck 5 a and the shoulder 5 c of the user 4. The substantially inverted U-shaped housing 2 is formed such that a portion disposed on the front neck portion 5g side of the user 4 is opened and a portion disposed on the rear neck portion 5b side is curved. .

  As shown in FIG. 2, when the user 4 wears the head-mounted speaker device 1 with the upper body being almost upright, the rear neck contact member 22 near the center of the housing 2 curved in a substantially inverted U shape. Is positioned in the vicinity of the rear neck 5b of the user 4, and both ends 21 and 23 of the substantially inverted U-shaped casing 2 are positioned from the shoulder 5c of the user 4 to the chest 5d beyond the collarbone 5e. Become. In the case of the present embodiment, the left and right speakers (3L, 3R) corresponding to stereo signals are arranged in front of the ear 5f of the user 4 and in the vicinity of the collarbone 5e in the necked speaker device 1. Is done.

  In the neck-mounted speaker device 1, the speaker 3 is fixed at a position away from the ear 5f of the user 4, so that the headphone is worn on the head and reproduces sound, or the earphone is worn on the ear and reproduces sound. The ears will not be blocked. In this respect, when the user 4 needs to pay attention to external sound other than the sound reproduced from the speaker 3, the necked speaker device 1 is more advantageous than the headphone. In addition, the neck-mounted speaker device 1 has an advantage that a sense of sound field with a sense of spaciousness can be obtained as compared with a headphone that is easily localized in the head.

  The neck-mounted speaker device 1 can be provided with an operation unit 30 that performs necessary operations such as power on / off and volume adjustment. For example, as shown in the perspective view of FIG. 1, in the neck-mounted speaker device 1 of the present embodiment, the user 4 can operate with the left hand on the left end portion 23 curved in a substantially inverted U shape of the housing 2. The operation unit 30 is provided as described above. Of course, the operation unit may be provided in a part other than the left end 23 of the housing 2.

  Since the neck-mounted speaker device 1 is an electronic device that is worn on the neck 5a and the shoulder 5c of the user 4, it can be deformed with some flexibility when worn so as not to damage the user's 4 body. Is preferred. In the coordinate axis shown in FIG. 1, when the neck-type speaker device 1 is displaced so that both end portions 21 and 23 of the substantially inverted U-shaped housing 2 are displaced in the X direction so that the space between them is widened, the user 4 The operation | work which mounts to the neck part 5a and the shoulder part 5c by moving to the Y direction from the back neck part 5b side can be made easy. The neck-mounted speaker device 1 according to the present embodiment can be deformed so that both end portions of the housing 2 are displaced in the X direction and the Z direction because a part of the housing 2 is formed of an elastic material. Become.

  The housing 2 of the neck-type speaker device 1 of the present embodiment is formed so as to be curved as a whole, and has a rear neck contact member 22 that contacts the rear neck 5 b of the user 4. The rear neck contact member 22 may be formed of a hard material such as a resin, or may be formed of a flexible material such as a thermoplastic elastomer material. When the rear neck contact member 22 is formed of a hard material such as resin and does not have flexibility, a relatively soft member between the rear neck contact member 22 and both ends 21 or 23 is used. It is preferable to provide an elastically deformable member that can be changed by elastic deformation.

  Further, the spinal column abutting member 10 is attached to the rear neck abutting member 22. The spinal column abutting member 10 is a member that extends from the rear neck 5b to the lower side along the cervical vertebra 5i on the back side of the user 4 and contacts the spinal column 5h. The spinal column abutting member 10 of this embodiment is a leather material having both hardness and softness, and is formed to have a substantially triangular shape. As shown in the figure, the rear neck contact member 22 and the spine contact member 10 maintain a predetermined angle (θ or φ) substantially orthogonal to the user 4 along the rear neck 5b and the spine 5h. Is attached. The spinal column abutting member 10 is fixed so that one side of the substantially triangular shape is wound around the rear neck abutting member 22, and the apex of the substantially triangular shape faces downward, and is applied from the rear neck 5 b to the spinal column 5 h over a wide area. It is formed to touch. Since this spinal column abutting member 10 is attached to the rear neck abutting member 22 with a snap, it can be removed as necessary.

  As shown in FIG. 2, the neck-type speaker device 1 including the spinal column abutting member 10 can be stably locked to the neck 5 a and the shoulder 5 c of the user 4 whose upper body is upright. Since the spine abutting member 10 abuts on the spine 5h on the back of the user 4, even if the body of the user 4 moves, it becomes difficult to cause a problem that the wearing state shifts or comes off, There is an advantage that can be mounted stably. If the head-mounted speaker device 1 does not include the spinal column abutting member 10, even if the upper body of the user 4 is in an upright state, the body of the user 4 moves or changes its posture. There is a risk that the mounting state may shift or change.

  FIG. 3 is a diagram illustrating a state in which the user 4 is in a forward leaning posture and the neck speaker device 1 is worn. Specifically, FIG. 3A shows the case of the neck-type speaker device 1 of the present embodiment, and FIG. 3B shows the case of the neck-type speaker device 100 of the comparative example. In FIG. 3, the left arm on the front side is not shown so that the state of the neck-type speaker device in the forward tilted posture can be easily seen. The neck type speaker device 100 of the comparative example is different from the neck type speaker device 1 of the present example only in that it does not include the spinal column abutting member 10 to be attached to the rear neck abutting member 22. To do.

  Since it is assumed that the user 4 in FIG. 3 drives the bicycle in a forward leaning posture, the front is lifted with his chin up, and the arm 5j is placed on the handle (not shown) of the bicycle located on the front side. Stretch out and support your upper body leaning forward. In the neck-mounted speaker device 1 or 100, even if the upper body of the user 4 is tilted forward, the left and right speakers (3L, 3R) are positioned in front of the user's 4 ear 5f and in the vicinity of the clavicle 5e. Can be arranged. Accordingly, the neck-mounted speaker device 1 or 100 can reproduce sound from the left and right speakers (3L, 3R) without blocking the ear 5f of the user 4.

  However, since the neck-mounted speaker device 100 of the comparative example does not include the spinal column abutting member 10, both ends of the housing 2 are located at the both ends of the user 4, particularly in the case of a forward leaning posture as shown in FIG. It becomes easy to move in the chest. This is because, when the user 4 changes from the upright state to the forward leaning posture, the mounting state changes so that the rear neck portion abutting member 22 is suspended from the rear neck portion 5b with which the housing 2 is in contact, and the housing 2 is This is because the rotating force acting to swing in the front-rear direction due to the working gravity works and swings in the front-rear direction. As a result, the neck type speaker device 100 may not be able to be stably locked and may not be able to exhibit a predetermined performance in audio reproduction.

  On the other hand, since the neck-mounted speaker device 1 of the present embodiment includes the spinal column abutting member 10 attached to the rear neck abutting member 22, the necked speaker device 1 is in a forward tilt posture as shown in FIG. Even if it exists, the movement which the both ends of the housing | casing 2 shakes and moves in the chest of the user 4 can be suppressed. Since the posterior cervical abutment member 22 and the spinal column abutment member 10 are attached so as to maintain a predetermined angle (θ or φ) that is substantially orthogonal, the spine abutment member 10 is the spine on the back of the user 4. Abuts against the portion 5h and can be mounted relatively stably.

  That is, the neck-type speaker device 1 is in contact with the spine even when the user 4 is in a forward leaning posture from an upright state and a rotational force is exerted to swing back and forth due to gravity acting on the housing 2. Since the member 10 supports, it can suppress shaking in the front-back direction. As a result, the neck type speaker device 1 can be stably locked and can exhibit a predetermined performance in sound reproduction.

  In addition, the spine part contact member 10 with which the neck type speaker device 1 is provided is not limited to the form as in the above embodiment. Even if the spinal column abutting member 10 has another shape and form, the rear neck abutting is performed so as to maintain a predetermined angle substantially orthogonal to the rear neck 5b and the spinal column 5h of the user 4. What is necessary is just to be attached to the member 22. FIG. Of course, the spinal column abutting member 10 is preferably attached to the rear neck abutting member 22 so as to be removable, but may be fixedly attached so as not to be removed.

  FIG. 4 is a diagram illustrating a necked speaker device 1a using a housing 2a which is an electronic device housing according to another preferred embodiment of the present invention. Specifically, FIG. 4A is a perspective view of the neck-type speaker device 1a as viewed from the right front side, and illustrates a state in which a spinal column abutting member 10a described later is accommodated. FIG. 4B is a perspective view of the neck-type speaker device 1a as viewed from the left rear side, and illustrates a state where the spinal column abutting member 10a is deployed.

  As shown in FIG. 4, the neck type speaker device 1a has the same configuration as the neck type speaker device 1 of the previous embodiment except that the configurations of the housing 2a and the spinal column abutting member 10a are different. . Therefore, in the following, the same components as those in the neck speaker device 1 of the previous embodiment are denoted by the same reference numerals, and the description thereof is omitted. Further, illustration and description of a part of the structure and internal structure of the neck-type speaker device 1a unnecessary for the description of the present invention are omitted.

  The neck-mounted speaker device 1a has a folding housing mechanism that can be used by expanding the spine contact member 10a housed in the housing 2a as needed. As shown in FIG. 4A, the casing 2a of the neck-type speaker device 1a accommodates the bending member 11 so that a part thereof is exposed on the right side 21 of both ends. A curved member 13 (not shown) is similarly housed in the left side 23 of the opposite end portions. The bending members 11 and 13 are respectively accommodated in the accommodation grooves 12 along the outer shape of the housing 2a. However, the bending members 11 and 13 are attached to the housing 2a so that one end side thereof can rotate around the shaft 11a or 13a.

  As shown in FIG. 4 (b), the bending members 11 and 13 are rotated about the shaft 11a or 13a, respectively, and the ends opposite to the ends on the shaft side are connected to each other to connect the rear neck. The connecting portion 14 can be configured below the contact member 22. Since the bending members 11 and 13 are longer in length than the distance between the shafts 11a and 13a, respectively, as a result, the connecting portion 14 is positioned below the rear neck contact member 22. For example, the connecting portions 14 of the bending members 11 and 13 may be provided with a convex portion at one end portion and a concave portion into which the convex portion is fitted at the other end portion.

  Accordingly, the connected bending members 11 and 13 constitute a substantially triangular spinal column abutting member 10a that abuts on the spine 5h on the back of the user 4. As in the case of the previous embodiment, the neck-type speaker device 1a including the spinal column abutting member 10a has the neck 5a and the shoulder of the user 4 regardless of whether the upper body is in an upright state or a forward leaning posture. It can be stably locked to the portion 5c. Further, the user 4 who is not used in the forward leaning posture uses the necked speaker device 1a by accommodating the bending members 11 and 13 in the housing 2a so that the spine contact member 10a does not appear. be able to. Since the spine abutting member 10a can be accommodated, the user 4 can easily carry the neck-type speaker device 1a.

  In the above embodiment, if a part of the casing 2 or 2a is formed of a flexible material, the clavicle between the end portions 21 and 23 from the neck portion 5a and the shoulder portion 5c of the user 4 to the chest portion 5d. It bends along the body in the vicinity of 5e, and the wearability of the neck type speaker device 1 is improved. That is, both ends of the housing 2 or 2a can be deformed so as to be displaced in the X direction and the Z direction, and can be worn along the body of the user 4. Since the size and shape of the neck 5a and the shoulder 5c of the user 4 vary depending on age, sex, and physique, various users 4 can be obtained by flexibly deforming the substantially inverted U-shaped casing 2 or 2a. It becomes possible to cope with. For example, even if the user 4 has a thick neck, if both ends of the substantially inverted U-shaped housing 2 or 2a are displaced in the X direction and elastically deformed so as to open between them, the neck hanging type The speaker device 1 or 1a can be attached.

  Similarly to the operation unit 30, the neck-mounted speaker device 1 or 1a may be provided so as to accommodate earphones that are wired. The earphone is an electroacoustic transducer that is inserted into the ear hole of the ear 5 f of the user 4 and reproduces sound, and can reproduce sound instead of reproducing sound from the speaker 3. In that case, there is an advantage that sound reproduced around the user 4 does not leak. The neck-mounted speaker device 1 may include a connection terminal for further connecting an earphone or a headphone. The neck-mounted speaker device 1 or 1a may be connected to a connection line for inputting an audio signal from another acoustic device.

  Similarly, if the neck-mounted speaker device 1 or 1a further includes a circuit such as a microphone that collects sound by converting sound waves into an audio signal, or a transmitter that transmits the collected audio signal, a telephone is provided. It can be used as a headset device capable of communication. The speaker 3 is preferably attached near the end of the housing 2 or 2a that is curved in a substantially inverted U shape, but it is not necessary to be a stereo type in which the speakers 3 are attached to both ends of the substantially inverted U shape. It may be a monaural neck-type speaker device 1 or 1a provided with a speaker.

  Further, the casing 2 or 2a of the neck-type speaker device 1 or 1a is not limited to one that is curved and formed in a substantially inverted U shape as long as it can be locked to the neck 5a and the shoulder 5c of the user 4. I can't. The shape of the housing 2 is not limited to a substantially symmetric shape, and may be an asymmetric shape having a short side and a long side. Moreover, the shape of the housing | casing 2 may be short so that the both ends of the substantially inverted U-shaped housing 2 or 2a do not reach the collar 5e of the user 4. Moreover, the shape of the housing | casing 2 may connect the both ends of the substantially inverted U-shaped housing | casing 2 or 2a, and may make an annular | circular shape.

  The neck-type speaker device 1 or 1a of the above-described embodiment is an example of an electronic device to be worn on the body of the user 4, and the electronic device using such an electronic device casing is the neck-type speaker device 1 or 1a. It is not limited to.
