This application claims priority under 35 U.S.C. §119(a) from Korean Patent Application Serial number 10-2014-0003991, which was filed on Jan. 13, 2014 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference in its entirety.
1. Field of the Disclosure
Various embodiments of the present disclosure relate to an electronic device, and for example, a speaker device and an electronic device including the same.
2. Description of the Related Art
Speaker devices output sound and generally, the speaker devices are installed to be fixed in an enclosure (a.k.a. “case”) having a predetermined space. Recently, however, speaker devices have been mounted in small-size electronic devices, such as mobile communication terminals, while providing high-quality sound. To secure such high-quality sound, a resonance space for sound generated by a speaker body is needed. The resonance space is provided around the speaker body to reinforce the sound output from the speaker body. In a small-size electronic device, a case for receiving the speaker body is provided to form a speaker module, thus providing the resonance space.
As the multimedia function of small-size electronic devices have increased, the size of a display device has also increased. In addition, much effort has been made to reduce a thickness of an electronic device for portability, together with the size increase of the display device.
The speaker device embodied in the form of a module receiving the speaker body in the case is useful for securing the resonance space, but may be difficult to mount within the thickness-reduced electronic device. Thus, the speaker body may be mounted inside the electronic device without using the case, and a part of an internal space of the electronic device may be reserved as the resonance space. However, in order to mount the speaker body inside the electronic device and secure the resonance space, a predetermined space inside the electronic device needs to be sealed.
In addition, in a structure of the electronic device where a plurality of elements, for example, a front case and a rear case are coupled, there may be a limitation in securing a sealing structure to provide a secured resonance space.
Moreover, in order to provide a secured resonance space, bonding may be performed to fix the speaker body within the electronic device, or to secure the sealing structure. Bonding has a shortcoming in that if the speaker body or other parts need to be replaced due to a failure or the like, the part and other parts bonded thereto may also need to be replaced.
The above information has been provided as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.
Aspects of the present disclosure have been made to at least partially solve, alleviate, or remove at least one of problems and/or disadvantages described above.
Accordingly, various aspects of the present disclosure provide a speaker device capable of easily securing a resonance space and an electronic device including the speaker device.
Various aspects of the present disclosure also provide a speaker device that is easy to install, separate, and replace, and an electronic device including the speaker device.
Moreover, various aspects of the present disclosure provide a speaker device capable of saving costs for repair or the like by facilitating replacement, and an electronic device including the speaker device.
Other objects to be provided in the present disclosure may be understood by the various embodiments described herein below.
According to an aspect of the present disclosure, there is provided a speaker device including a speaker body, which has a front surface, a rear surface, and a side surface that is arranged between the front surface and the rear surface, and a sealing member positioned to enclose at least the side surface of the speaker body, in which the sealing member isolates sound that is output through the front surface of the speaker body from sound that is output through the rear surface of the speaker body.
According to another aspect of the present disclosure, there is provided an electronic device including a speaker device, the electronic device having a pair of case members mounted to face toward each other, a speaker body including a front surface, a rear surface, and a side surface that is arranged between the front surface and the rear surface, and a sealing member provided to enclose at least the side surface of the speaker body, in which the sealing member is mounted on a first case member of the case members, and the sealing member and the first case member isolate sound output through the front surface of the speaker body from sound output through the rear surface of the speaker body.
In addition, the electronic device may further include a sound output hole formed in a second case member of the case members and a sound waveguide formed in the sealing member to communicate with the sound output hole, in which the front surface of the speaker body is positioned to face the second case member and the sound output through the front surface of the speaker body is delivered to the sound output hole through the sound waveguide.
The sound output hole may extend from, for example, a surface of the second case member so as to pass through a side surface of the second case member.
The electronic device may further include a support rib formed on a surface of the first case member, in which the support rib has a closed-curve shape enclosing the sealing member.
The sealing member may be compressed between the speaker body and the support rib, thus forming a sealing structure.

[Embodiments]
As illustrated in
A speaker device 104 is mounted on the first case member 101. A support rib 113 is formed on a surface of the first case member 101 to provide a means for mounting and fixing the speaker device 104. The support rib 113, which is in a closed-curve shape enclosing the speaker device 104, protrudes from the surface of the first case member 101.
As shown in
At least one of sealing protrusions and protruding portions may be provided on an inner (first) surface and an outer (second) surface of the sealing member 105, respectively.
With continued reference to
A first protruding portion 151a′ from among the plurality of protruding portions has a closed-curve shape formed on the inner surface of the sealing member 105 and is provided to enclose the outer circumferential surface of the speaker body 141. A second sealing protrusion 151b′ from among the plurality of sealing protrusions has a closed-curve shape formed on the outer surface of the sealing member 105 and is provided to correspond to the inner surface of the support rib 113. Recessed portions 151c and 151d are formed in the speaker body 141 and the support rib 113 to correspond to the first protruding portion 151a′ and the second protruding portion 151b′. If the speaker device 104 is installed in the first case member 101, the first protruding portion 151a′ and the second protruding portion 151b′ are engaged with the corresponding recessed portions 151c and 151d, respectively, to set an assembly position of the sealing member 105 with respect to the speaker body 141 and an assembly position of the speaker device 104 with respect to the first case member 101. If the first protruding portion 151a′ and the second protruding portion 151b′ have larger sizes than the corresponding recessed portions 151c and 151d, then formation of the sealing structure as well as setting of the assembly positions may be possible. For example, the first protruding portion 151a′ and the second protruding portion 151b′ may form a sealing structure, depending on their sizes, similarly with the first sealing protrusion 151a and the second sealing protrusion 151b.
When embodiments of the present disclosure are described, the examples show and describe the sealing protrusion 151a and the protruding portion 151a′ being formed on the inner surface of the sealing member 105 and the sealing protrusion 151b and the protruding portion 151b′ being formed on the outer surface of the sealing member 105, respectively. However, a plurality of sealing protrusions and a plurality of protruding portions may be arranged in various positions on the inner surface and the outer surface of the sealing member 105, respectively. For example, in
To output sound from the speaker device 104, the electronic device 100 may include a sound waveguide 151 and a sound output hole 111. If the first case member 101 and the second case member 102 are coupled to face each other when the speaker device 104 is mounted on the first case member 101, then the sound waveguide 151 may be formed between a front surface of the speaker device 104 and the second case member 102. Alternatively, the hole could be bounded by the first case member 101 and the second case member 102. The sound waveguide 151 may have a form so to an opening extending from the front surface of the speaker device 104 to a side edge of the speaker device 104.
The sound output hole 111 is formed in the second case member 102. The sound output hole 111 extends from a surface of the second case member 102 to penetrate through a side surface of the second case member 102. According to an embodiment, the sound output hole 111 may be formed to penetrate through the side surface of the second case member and another surface of the second case member 102 so as to permit the communication of sound through the waveguide and exits via the output hole, and a separate sound guide member may be installed to implement the shape of the sound output hole 111 illustrated in
To isolate a sound output path formed by the sound waveguide 151 and the sound output hole 111 from other regions, the electronic device 100 may further include a second sealing member 129 (as shown in
For example, a sound pressure may leak through a gap or space formed between the first case member 101 and the second case member 102, and by disposing the second sealing member 129 therebetween, such leakage may be prevented.
With reference to
As shown in
The third case member 103 is coupled to enclose the rear surface of the speaker device 104. In a region enclosing the rear surface of the speaker device 104 inside the third case member 103, a resonance space 149 may be formed. For example, a part of an inner surface of the third case member 103, the first case member 101, and the speaker device 104 may be combined to provide the resonance space 149. If the resonance space 149 is provided on the inner surface of the third case member 103, a third sealing member 139 may be further provided between the first case member 101 and the third case member 103. The third sealing member 139 is attached to one of the third case member 103 or the first case member 101 and so as to form an enclosure of the rear surface of the speaker device 104. Similar to the second sealing member, the third sealing member 139 may be formed of an anti-vibration material such as a Poron® tape.
Thus, the electronic device 100 according to embodiments of the present disclosure may secure a resonance space without a need to install a separate case. Moreover, the sealing member 105 and the first case member 101 may isolate sound output through the front surface of the speaker body 141 and sound output through the rear surface of the speaker body 141 from each other. Therefore, the electronic device 100 may provide sound of good quality in spite of being reduced in size and thickness.
Herein below, various implementation examples of the speaker device 104 will now be described with reference to
Referring to
The speaker body 141 may include a minimum of elements capable of substantially generating sound. The speaker device 104 according to embodiments of the present disclosure may be implemented using a speaker body having a complete structure capable of generating sound, and thus figures and a detailed description corresponding to a detailed structure of the speaker body 141 will not be provided.
The sealing member 105 is provided to enclose the side surface provided between the front surface and the rear surface of the speaker body 141, and is formed of an elastic material such as rubber, silicon resin, or the like. As the sealing member 105 is made of elastic material, the sealing member 105 is compressed to some degree when the speaker device 104 is mounted on the first case 101, such that the sealing member 105 stably fixes the speaker device 104 to the first case member 101, forming a sealing structure.
As previously-mentioned, the sealing member 105 may include the first sealing protrusion 151a and the second sealing protrusion 151b formed on the inner surface and the outer surface of the sealing member 105, respectively. The first sealing protrusion 151a and the second sealing protrusion 151b protrude from the inner surface and the outer surface of the sealing member 105, respectively, and form a closed curve extending along the circumferential direction of the sealing member 105. Although it is described above with reference to
The sealing member 105 may include a cover member 153 that covers a part of the front surface of the speaker body 141. A double-sided tape is provided on an inner surface of the cover member 153 to attach the front surface of the speaker body 141 to the inner surface of the cover member 153. Thus, the speaker body 141 may be fixed in close contact with the sealing member 105.
A part exposing the front surface of the speaker body 141 in which the cover member 153 is not formed, may be used as the sound waveguide 151. For example, if the first case member 101 and the second case member 102 are coupled to face each other, the outer surface of the cover member 153 contacts the second case member 102, such that the sound waveguide 151 opened toward a side end of the sealing member 105 may be formed. In other words, the sound waveguide 151 may be formed between a part of the front surface of the speaker body 141, which is exposed to outside, and the second case member 102 to have the same thickness as that of the cover member 153. Thus, sound output through the front surface of the speaker body 141 is guided by the sound waveguide 151 to the sound output hole 111, and is isolated from sound output through the rear surface of the speaker body 141.
The speaker device 104 according to the current embodiment is different from the previous embodiment in that the sealing member 105 provides a stable sealing structure while fixing a signal wire 143 extending from the speaker body 141. If the signal wire 143 needs to be disposed toward the front surface of the speaker body 141 while extending from the rear surface of the speaker body 141, a sealing structure may also be provided in a layout path of the signal wire 143. The signal wire 143 may be provided in various forms such as a Flexible Printed Circuit Board (FPCB), a coaxial cable, a conductive wire, and the like.
Referring to the illustrations shown in
When the speaker device 104 is coupled to the first case member 101, the fixing member 155 is also coupled in a position enclosed by the support rib 113, such that the fixing member 155, together with the sealing member 105, is compressed in close contact with the outer circumferential surface of the signal wire 143. Thus, the signal wire 143 is fixed and a stable sealing structure may be formed between the speaker body 141 and the support rib 113. This sealing structure may secure more stable performance with sealing protrusions on the outer circumferential surface of the fixing member 155.
