Description

  The present invention relates to an electronic device housing and an electronic device using the electronic device housing.

  For example, a neck-type speaker device, which is an electronic device worn on the user's neck, has a shape and configuration similar to an overhead headphone placed on the 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 may be attached to a curved housing. In the neck-mounted speaker device, the speaker that emits sound waves 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.

  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. .

  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 to the inside of 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 electronic device casings suitable for electronic devices to be worn on the user's body, such as neck-mounted speaker devices and neck-mounted speaker devices, have been proposed.

  The neck-type speaker device includes, for example, a neck-type speaker that can be necked in a non-contact state with a 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 this embodiment of the neck speaker, the part touched by the neck is covered with a cover made of urethane resin, EVA resin, foam rubber or the like having an appropriate fit and elasticity.

  In addition, for the purpose of protecting the electronic device from impact and vibration, a covering member made of an elastomer material having thermoplastic or thermosetting elasticity may be provided around the casing. By covering the outside of the housing formed of a strong resin material or metal material with, for example, an elastic silicon rubber member, the electronic device can be mounted on the user's body. In some cases, the housing of the electronic device is intended to be waterproofed by covering with a silicon rubber member. Conventionally, the anti-vibration support is characterized by comprising a molded body mainly composed of a thermoplastic elastomer, and at least partially including an electric component, a mechanical component, or a mechanism seat including these components. A body invention has been disclosed (Patent Document 3).

  However, the prior art is not sufficient to construct a casing of an electronic device such as a neck-type speaker device that can be locked to the neck and shoulders of a user. If a hard housing is provided and all of it is covered with a covering member made of an elastomer material, the appearance and texture of the covering member are governed by the texture of the covering member, and the electronic device or neck-mounted speaker device that is worn on the user's body May not be appropriate. Also, if the housing of a hard electronic device such as a metal material or a resin material is removed and only covered with a covering member, the electronic device component including the internal substrate component, electronic component, mechanical component or wiring component is shocked. And cannot be protected from vibration.

  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 an electronic device casing and an electronic device using the electronic device casing. It is an object of the present invention to provide an electronic device casing that is configured with a possible casing and protects parts of the electronic device from impacts and vibrations and that is excellent in aesthetics and texture, and an electronic device that uses the electronic device casing.

  The electronic device casing of the present invention is an electronic device casing that accommodates and attaches components including board components, electronic components, mechanical components, or wiring components, and is formed from an elastomer material having thermoplastic or thermosetting elasticity. A base member that is formed of a resin material or a metal material and is attached to the base member so as to cover a part of the base member, and the base member is not covered with the outer shell member and is an elastomer. An internal space having an exposed portion where the material is exposed and a non-exposed portion which is covered with the outer shell member and where the elastomer material is not exposed, and the non-exposed portion of the base member accommodates a part on the inner side of the outer shell member And a component fixing part for fixing the component.

  Preferably, in the electronic device casing of the present invention, the base member is formed so as to connect the plurality of non-exposed portions and the plurality of non-exposed portions, and the relative positions of the non-exposed portions can be changed by elastic deformation. And at least an exposed portion formed as described above.

  Preferably, in the electronic device casing of the present invention, the exposed portion of the base member has an internal passage that communicates the internal spaces of the plurality of non-exposed portions therein, or a plurality of non-exposed portions therein. Wiring components for connecting components attached to the respective internal spaces of the exposed portion are embedded.

  Preferably, in the electronic device casing of the present invention, the outer shell member further includes a component fixing portion to which the component is attached.

  Preferably, the electronic device casing of the present invention includes a plurality of base members, and at least one outer shell member includes a non-exposed portion of one base member and a non-exposed portion of another base member. A plurality of base members are connected together.

  Preferably, the electronic device of the present invention includes an electronic device casing and a component attached to a component fixing portion of the electronic device casing.

  The operation of the present invention will be described below.

  The electronic device casing according to the present invention includes a base member formed of an elastomer material having thermoplastic or thermosetting elasticity, and a base member formed of a resin material or a metal material so as to cover a part of the base member. An outer shell member to be attached. Since the base member is formed of an elastomer material, the base member is flexible and suitable for constituting an electronic device casing that is worn on the user's body. The base member has an exposed portion where the elastomer material is exposed without being covered by the outer shell member, and a non-exposed portion where the elastomer material is not exposed while being covered with the outer shell member.

  Here, the non-exposed portion of the base member has a component fixing portion that defines an internal space for accommodating components on the inner side of the outer shell member and fixes the components. Therefore, the electronic device casing can accommodate and attach components including board components, electronic components, mechanism components, or wiring components to configure the electronic device. Since the parts of the electronic device are housed and fixed in the non-exposed portion of the base member that is covered and protected by the hard outer shell member, even if the electronic device is worn on the user's body, the electronic device is protected from impact and vibration. Can protect the parts. Of course, the outer shell member may further include a component fixing portion to which the component is attached.

  Further, since the base member has an exposed portion where the elastomer material is exposed without being covered by the outer shell member, and a non-exposed portion where the elastomer material is not exposed while being covered with the outer shell member, all are made of the elastomer material. The aesthetics and texture of the electronic device can be improved as compared with the case of covering with a covering member. The base member has a plurality of non-exposed portions and an exposed portion formed so as to connect the plurality of non-exposed portions so that the relative position of the non-exposed portions can be changed by elastic deformation. In such a case, since the exposed portion is bent due to elastic deformation, it is possible to configure an electronic device casing suitable for being mounted on the user's body.

  The exposed portion of the base member has an internal passage for communicating the internal spaces of the plurality of non-exposed portions in the interior thereof, or a component attached to each internal space of the plurality of non-exposed portions is connected to the inside of the exposed portion. Wiring parts are preferably embedded. The outer shell member may further include a component fixing portion for attaching the component. Even if it does not have a hard case that covers all of it with a covering member made of an elastomeric material like the prior art, it can be deformed along the user's body by wearing an elastically deformable base member. A suitable electronic device casing can be configured.

  Further, the electronic device housing includes a plurality of base members, and at least one outer shell member covers both the non-exposed portion of one base member and the non-exposed portions of the other base members. By connecting the members, it is possible to realize an expansion / contraction mechanism for the housing that allows part of the non-exposed portion to be exposed and the distance between the two base members to be adjusted.

  The electronic device casing and the electronic device using the same according to the present invention protect the components of the electronic device from impacts and vibrations, and constitute a casing that can be mounted along the user's body, so that the appearance and texture are excellent. An electronic device housing and an electronic device using the electronic device housing can be realized.

  Hereinafter, although the electronic device housing | casing by preferable embodiment of this invention and an electronic device using the same are demonstrated, this invention is not limited to these embodiment.

  FIGS. 1-5 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, FIG. 2 is a diagram for explaining a mounting state of the neck-type speaker device 1, and FIG. FIG. 4 is an enlarged view of a part of the housing 2. FIG. 4B is a cross-sectional view of the A-A ′ cross section in FIG. Further, FIG. 5 is a diagram illustrating the configuration of the operation unit 30 of the necked 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. Moreover, in FIGS. 1-5, the boundary of a ridgeline part or a structural surface is described with the thin line or the dashed-two dotted line so that the shape of components may be understood easily. 4 and 6, a part of the housing 2 is shown in a transparent manner.

  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. When the user 4 wears the neck-mounted speaker device 1, the central portion of the casing 2 curved in a substantially inverted U shape is positioned near the rear neck 5 b of the user 4, and the approximately inverted U-shaped casing 2. Both ends of the user 4 are located from the shoulder 5c of the user 4 to the chest 5d beyond the collarbone 5e. 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.

  Since the neck-mounted speaker device 1 is an electronic device that is worn on the neck 5a and shoulder 5c of the user 4, it is preferable that the neck-hanging speaker device 1 can be flexibly deformed when worn so as not to damage the user's 4 body. In the coordinate axes shown in FIG. 1, the neck-type speaker device 1 has a rear neck portion of the user 4 when the both ends of the substantially inverted U-shaped housing 2 are displaced in the X direction so that the space between them is wide open. The operation | work which mounts to the neck part 5a and the shoulder part 5c so that it may move to the Y direction from the 5b side can be made easy. The neck-mounted speaker device 1 of the present embodiment includes a base member 10 formed of an elastomer material having thermoplastic or thermosetting elasticity, as will be described later. The part can be deformed so as to be displaced in the X direction and the Z direction.

  The casing 2 of the neck-type speaker device 1 according to the present embodiment includes a plurality of resins on one base member 10 formed of a silicone resin that is a thermoplastic elastomer material so that the entire case 2 is curved in a substantially inverted U shape. The outer shell member (21, 23, 25, 27, 29) formed from is attached. The base member 10 includes an unexposed portion (11, 13, 15, 17, 19) where the elastomer material is not exposed by being covered with the outer shell member, and an exposed portion (12 where the elastomer material is exposed without being covered by the outer shell member). , 14, 16, 18) are arranged alternately. The outer thickness of the non-exposed portion (11, 13, 15, 17, 19) of the base member 10 is smaller than the outer thickness of the exposed portion (12, 14, 16, 18). (21, 23, 25, 27, 29) are attached so as to cover the non-exposed portions (11, 13, 15, 17, 19) of the base member 10.

  Since the base member 10 is formed of a flexible thermoplastic elastomer material, the thin non-exposed portion and the thick exposed portion can be molded integrally. Therefore, a component such as an electronic component attached to a speaker or a board can be attached to the non-exposed portion (11, 13, 15, 17, 19) covered with the outer shell member (21, 23, 25, 27, 29). Alternatively, the housing 2 that can be flexibly deformed can be configured by providing an exposed portion (12, 14, 16, 18) that can be accommodated and elastically deformable to connect the non-exposed portions together.

  The outer shell members (21, 23, 25, 27, 29) of the present embodiment are configured by two members (for example, outer shell members 21a and 21b) that are connected so as to sandwich the base member 10 from above and below, respectively. ing. Since the outer shell member is formed of a resin material having no flexibility, the unexposed portions (11, 13, 15, 17, 19) of the base member 10 covered with the outer shell member are flexible thermoplastic. Even if it is made of an elastomer material, it will not be deformed. Therefore, the non-exposed portion of the base member 10 is suitable for housing components constituting the electronic device on the inner side of the outer shell member.

  For example, as shown in FIG. 4, the non-exposed portion 13 provided between the exposed portions 12 and 14 of the base member 10 is an internal space that accommodates components inside the outer shell member 23 attached to the non-exposed portion 13. 13a can be defined. Specifically, the non-exposed portion 13 is provided with a recess for defining the internal space 13a, and a boss 13b as a component fixing portion for fixing the substrate 6 to which the electronic component 7 is attached is provided inside thereof. It has been. Since the boss 13b is formed of a flexible thermoplastic elastomer material, the boss 13b can be protected and supported / attached so as not to transmit vibration from the outside to the substrate 6. Further, outer shell members 23a and 23b are attached to the non-exposed portion 13 so as to cover the internal space 13a.

  Accordingly, if the outer shell members 23a and 23b are attached to the non-exposed portion 13 of the base member 10 without any gaps, the outer shell member 23a and 23b are waterproofed so that moisture or dust from the outside does not enter the inner space 13a in which the substrate 6 is accommodated. Dust protection can be achieved. In the internal space of the non-exposed portion of the base member 10, for example, an amplifier circuit that amplifies an audio signal reproduced by the necked speaker device 1, a receiving circuit that receives a radio signal, a power supply circuit including a battery, and the like. It can be accommodated in such a way that it can withstand external impacts and does not transmit vibration.

  Moreover, the outer shell member may have a component fixing part to which a component is attached. For example, as shown in FIG. 1, the outer shell member 21 or 29 that covers the unexposed portions 11 or 19 at both ends of the base member 10 accommodates speakers (not shown) 3R or 3L, respectively. The speaker 3R or 3L is attached to the inside of the outer shell member 21 or 29. The outer shell member 21 or 29 is provided with a sound hole 20 through which a sound wave emitted from the speaker 3R or 3L passes. Of course, the speaker 3R or 3L may be fixed to the non-exposed portion 11 or 19.

  Since the exposed portion of the base member 10 is formed of a flexible thermoplastic elastomer material, the exposed portion of the base member 10 is formed so as to be able to change by elastic deformation by connecting a plurality of non-exposed portions, and a plurality of non-exposed portions therein. The internal passage (not shown) which connects each internal space of a part is provided. Through this internal passage, a wiring material for connecting circuit boards attached to the non-exposed portion as described above, a core material for reinforcing the strength of the exposed portion, or the like can be passed. Wiring components that connect components attached to the internal spaces of the plurality of non-exposed portions may be embedded in the exposed portion. The wiring member, the wiring component, and the core member can be disposed inside the exposed portion of the base member 10 by insert molding or the like when the base member 10 is formed of a thermoplastic elastomer material.

  The exposed portion of the base member 10 is formed of a thermoplastic elastomer material so that the exposed portions of the base member 10 can be changed by elastic deformation by connecting a plurality of unexposed portions, so that the user 4 moves the neck-type speaker device 1 along the body. Can be mounted as follows. For example, as shown in FIG. 2 (b), when the user 4 wearing the head-mounted speaker device 1 is viewed from the side, the speaker 3L provided on one end side of the substantially inverted U-shaped housing 2 is attached. The shell member 29 is located along the chest 5d of the user 4. The non-exposed portion 19 covered by the outer shell member 29 is connected to the non-exposed portion 17 on the rear neck portion 5b side of the user 4 and the exposed portion 27 covering this by an exposed portion 18 that can be elastically deformed.

  In the present embodiment, the exposed portion 18 of the base member 10 is formed of a thermoplastic elastomer material, and is formed so that its thickness is reduced in the vicinity of the clavicle 5e. Therefore, the exposed portion 18 bends naturally along the body in the vicinity of the collarbone 5e from the neck portion 5a and the shoulder portion 5c to the chest portion 5d of the user 4, so that the wearability of the neck type speaker device 1 is improved. Note that, similarly to the exposed portion 18 located on the left side of the user 4, the same applies to the exposed portion 12 on the right side corresponding to the opposite side of the axis target.

  That is, since the housing 2 of the neck-type speaker device 1 includes the base member 10 formed of an elastomer material having thermoplasticity or thermosetting elasticity, both ends of the housing 2 are displaced in the X direction and the Z direction. It becomes possible to deform | transform so that it can mount | wear along the user's 4 body. The size and shape of the neck 5a and the shoulder 5c of the user 4 vary depending on age, gender, and physique, so that the substantially inverted U-shaped housing 2 can be flexibly deformed to support various users 4 become able to. For example, even if the user 4 has a thick neck, the plurality of exposed portions of the base member 10 are elastically deformed so that both end portions of the substantially inverted U-shaped housing 2 are displaced in the X direction and opened between them. By doing so, the neck type speaker device 1 can be mounted.

  Since the neck-mounted speaker device 1 does not cover the entire housing 2 with a covering member made of an elastomer material, there is an advantage that the aesthetic appearance and texture are not controlled only by the elastomer material. In the case of a conventional housing structure in which only silicon resin appears on the surface, the aesthetics and texture of the entire device are affected by the color or gloss of the silicon resin material, and the design as an electronic device worn on the body of the user 4 May be unattractive.

  In this respect, the base member 10 constituting the housing 2 is formed of a flexible thermoplastic elastomer material, and the exposed portion where the elastomer material is exposed without being covered by the outer shell member, and the outer shell member is covered. Since it has a non-exposed portion where the elastomer material is not exposed, a resin material or a metal material excellent in aesthetics and texture can be used for the outer shell member. Therefore, it is possible to realize the neck-type speaker device 1 that protects the built-in components from impact and vibration, and is excellent in aesthetics and texture.

  Since the plurality of exposed portions of the base member 10 are portions where the thermoplastic elastomer material having a large friction coefficient is exposed, it functions as an anti-slip when the neck type speaker device 1 is worn on the body of the user 4. Therefore, even when the user 4 moves, it is possible to make it difficult to cause a problem that the wearing state shifts or comes off.

  The base member 10 of the housing 2 of the neck-type speaker device 1 is not limited to a thermoplastic elastomer material such as silicone resin, but is a thermosetting elastic material such as another thermoplastic elastic material or a rubber material. It may be. For example, in addition to the silicon resin, a rubber material, an elastomer resin material, or a PVC (polyvinyl chloride) resin material may be used. The outer shell member of the housing 2 is not limited to a resin material such as PP resin, PC resin, or ABS resin, and may be a metal material such as an aluminum alloy, a titanium alloy, or a magnesium alloy.

  Further, in the neck-mounted speaker device, if heavy components such as a speaker, a circuit board, a battery, etc. are arranged only on both end sides of the substantially inverted U-shaped housing 2, the chest 5d of the user 4 is placed. As a result, the center of gravity is biased to the side, and as a result, the central portion of the substantially inverted U-shaped housing 2 may hit the rear neck 5b of the user 4 strongly. Therefore, in the neck-type speaker device 1 of the present embodiment, since a plurality of components can be arranged in a distributed manner at the positions of the plurality of non-exposed portions of the substantially inverted U-shaped casing 2, the center of gravity It is possible to make it easy to wear with proper position. For example, not only the substrate 6 and the circuit component 7 are provided inside the outer shell member 23, but also the substrate 6 and the circuit component 7 having the same weight may be provided inside the outer shell member 27 at a symmetrical position. Further, a heavy battery component may be provided inside the outer shell member 25 at a position corresponding to the rear neck portion 5 b of the user 4.

  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. 5A, in the neck-type speaker device 1 of the present embodiment, the outer shell member 21 located on the right side of the end of the housing 2 curved in a substantially inverted U shape. In addition, an operation unit 30 is provided so that the user 4 can operate with the right hand. Of course, the operation unit may be provided in a portion other than the outer shell member 21 of the housing 2.

  However, as can be seen with reference to FIG. 2, the operation unit 30 provided on the outer shell member 21 of the housing 2 of the neck-type speaker device 1 is positioned at the lowest side of the field of view of the user 4. It may be difficult to see and operate during normal use. The user 4 may have to face down to operate the operation unit 30. In the case where the operation unit 30 is provided in a portion other than the end curved in a substantially inverted U shape, it is difficult to see and operate.

  Therefore, in the neck-mounted speaker device 1 according to the present embodiment, as shown in the perspective view of FIG. 5 (b), the operation unit 30 can be taken out from the storage unit 31 that is a recess provided in the outer shell member 21. I am doing so. The operation unit 30 can be remotely operated by connecting the neck-type speaker device 1 via the connection line 32. If the operation unit 30 housed in the housing unit 31 is pulled out to a position where the user 4 can enter the field of view, the user 4 does not have to face down to operate the operation unit 30. The connection line 32 is wound and accommodated by a winding mechanism (not shown in FIG. 2) provided on the inner side of the outer shell member 21 that covers the non-exposed portion 11 of the base member 10. Therefore, when the operation unit 30 is not operated, it can be accommodated by being engaged with the housing 2.

  Similarly to the operation unit 30, the neck speaker device 1 may be provided with a wire-connected earphone that can be accommodated. 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. Further, the neck type speaker device 1 may be connected to a connection line for inputting an audio signal from another acoustic device.

  Similarly, if the neck-mounted speaker device 1 further includes circuits such as a microphone that collects sound by converting sound waves into sound signals or a transmitter that transmits the collected sound signals, telephone communication is possible. It can be used as a possible headset device. The speaker 3 is preferably attached near the end of the housing 2 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, and the speaker is attached only to one side. The monaural neck-mounted speaker device 1 may be provided.

  Further, the casing 2 of the neck-mounted speaker device 1 is not limited to the one that is bent 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. 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. The shape of the housing 2 may be short so that both end portions of the substantially inverted U-shaped housing 2 do not reach the clavicle 5e of the user 4. Moreover, the shape of the housing | casing 2 may connect the both ends of the substantially reverse U-shaped housing | casing 2, and may make it a ring shape.

  The neck-type speaker device of the above embodiment is an example of an electronic device that is worn on the user's body, and the electronic device using such an electronic device casing is not limited to the neck-type speaker device. Even if the electronic device is not worn on the user's body, it can be adopted if it is an electronic device that the body touches when operated by the user, or an electronic device that needs to cope with strong impact or vibration.

  FIG. 6 is a diagram for explaining the configuration of the casing of the neck type speaker device according to another preferred embodiment of the present invention. Specifically, the case 2 constituting the necked speaker device includes two base members formed of an elastomer material having thermoplasticity or thermosetting elasticity, and the two base members are It is an enlarged view explaining the expansion-contraction mechanism which enables adjustment of the separation distance.

  In FIG. 6A and FIG. 6B, the inner side which is covered with the outer shell member 25 and cannot be seen is shown in a transparent manner. In the following, illustration and description of a part of the structure of the neck type speaker device unnecessary for the description of the present invention, the internal structure, and the like are omitted. Moreover, about the same structure demonstrated in the said Example, the same name and code | symbol are attached | subjected and description is abbreviate | omitted.

  One base member constituting the housing 2 has an exposed portion 44 and a non-exposed portion 45a, and the other base member has a non-exposed portion 45b and an exposed portion 46. Similar to the above-described embodiment, the outer thickness of the non-exposed portions 45a and 45b is smaller than the outer thickness of the exposed portion 44 and the exposed portion 46. The unexposed portions 45a and 45b are covered and connected together by the outer shell member 25. However, the non-exposed portions 45 a and 45 b can slide inside the outer shell member 25.

  On the inner side of the outer shell member 25, a space 25c having a separation distance d is provided between the non-exposed portion 45a and the non-exposed portion 45b. FIG. 6A shows a case where the expansion / contraction mechanism is adjusted to the shortest. All the unexposed portions 45a and 45b are accommodated inside the outer shell member 25, and the separation distance d is shortened. On the other hand, FIG. 6B shows the case where the telescopic mechanism is adjusted to be the longest, and the non-exposed portions 45a and 45b are almost all exposed to the outside of the outer shell member 25, and the separation distance d is long. Thus, if the separation distance d between the two base members defining the size of the space 25c is changed, the expansion / contraction mechanism can be adjusted to be short / long.

  At the end portions of the non-exposed portions 45a and 45b of the base member, projecting portions 45d that project like flanges are provided. Further, the end portions of the outer shell member 25 are respectively provided with projecting portions 25d that project like flanges, and these projecting portions are also provided when the expansion / contraction mechanism is adjusted to be the longest as shown in FIG. 45d and the protrusion part 25d can engage, and the connection of the exposed parts 45a and 45b and the outer shell member 25 can be maintained.

  The neck-type speaker device of the present embodiment includes a base member formed of an elastomer material having thermoplastic or thermosetting elasticity, so that both ends of the housing 2 are displaced in the X direction and the Z direction. In this way, it is possible to modify the same as in the above embodiment. The neck-mounted speaker device according to the present embodiment has an advantage that it can be worn according to the body of the user 4 because the casing further has an expansion / contraction function.

  The telescopic mechanism of the present embodiment can be provided at a plurality of locations of the casing of the neck type speaker device. For example, the outer shell member 25 including the expansion / contraction mechanism may be provided at one location of the outer shell member corresponding to the central portion of the substantially inverted U-shaped casing 2, You may provide in two places of a position. If the dimension that can be expanded and contracted is increased, there is an advantage that it can be fitted to a wider range of users 4.

  The electronic device casing and the electronic device using the same according to the present invention are not limited to home stereo reproduction or telephone communication, but can be applied to in-vehicle audio devices and sound reproduction facilities such as movie theaters.
