  7. The electronic device (101, 102, 104) of claim 5, wherein the roller housing (401) comprises a groove (41) recessed in an outer circumferential surface (40a) thereof such that the conductive connecting member (30) is wound to or unwound from the groove (41).
  8. The electronic device (101, 102, 104) of claim 7, wherein the conductive connecting member (30) comprises: a first portion (310, 312, 314) located inside the roller housing (401); and a second portion branched from the first portion (310, 312, 314) and located outside the roller housing (401) to be wound to or unwound from the groove (41).
  9. The electronic device (101, 102, 104) of claim 8, wherein the conductive connecting member (30) comprises three connectors (311, 313, 315) comprising: a first connector (311, 313, 315) disposed at one end of the first portion (310, 312, 314) and connected to the first speaker (420, 450); a second connector (313) disposed at the other end of the first portion (310, 312, 314) and connected to the second speaker (422, 452); and a third connector (315) disposed at an end of the second portion and connected to the circuit board (225).
  10. The electronic device (101, 102, 104) of claim 1, wherein the one or more speakers (420, 422, 460) are configured to use an inner space (40b) of the guide member (25) as an enclosure acoustic resonance section.
  11. The electronic device (101, 102, 104) of claim 1, wherein the second housing (22) is configured to slide in or out along a longitudinal direction of the first housing (21).
  12. The electronic device (101, 102, 104) of claim 5, wherein the roller housing (401) comprises a sound absorbing material (43) in the inner space (40b).

Description

[Technical Field] Various embodiments of the disclosure relate to an arrangement of speakers of a sliding-type electronic device. [Background Art] Two types of speakers may be arranged in an electronic device such as a smartphone. For example, one speaker may be disposed at the bottom end of the electronic device to serve as a main speaker, and the other speaker may be disposed at the upper end of the front surface of the electronic device to serve as a receiver for transmitting call voice. The speaker disposed at the lower end of the electronic device is a closed-type speaker and may include an enclosure structure in itself. Such an enclosure structure may play a role in preventing air pressure generated during the operation of the speaker from spreading out to the outside. The enclosure structure of the speaker may play an important role in speaker acoustic performance, and the larger the volume of the enclosure, the better the sound in the low-frequency band. Meanwhile, the speaker disposed at the top end of the front surface of the electronic device is an open-type speaker and does not have an enclosure structure. Thus, a separate enclosure structure may be required. For example, the open-type speaker may use a partial space inside an electronic device as an enclosure structure. A mobile terminal in which a size of a displayed screen is adjusted by a user and which includes speakers is known from EP 3 322 160 Al. EP 3 258 675 A1 discloses a twin-housing sliding arrangement wherein a cylindrical roller guides movement of the display. [ Disclosure of Invention] [Technical Problem] However, when an electronic device is a sliding-type electronic device, for example, an electronic device that includes a first housing and a second housing, and the second housing slides from the first housing, since a driver (driving unit) configured to provide sliding movement is disposed in the first housing, it may be difficult to arrange speakers due to lack of space to place the speakers. According to various embodiments of the disclosure, it is possible to provide an electronic device in which a speaker may be arranged by using an inner space of a driver disposed in a housing as an enclosure. According to various embodiments of the disclosure, it is possible to provide an electronic device in which stereo-speakers may be arranged by using an inner space of a driver disposed in a housing as an enclosure. According to various embodiments of the disclosure, it is possible to provide an electronic device in which stereo-type speakers may be arranged by using an inner space of a guide member disposed in a housing as an enclosure. [Solution to Problem] The invention is defined by the independent claims. Preferred embodiments of the invention are matter of the dependent claims. [Advantageous Effects of Invention] According to various embodiments of the disclosure, in an electronic device, an inner space of a driver disposed in a housing used is as an enclosure for a speaker so that a space required for disposing a speaker can be reduced.
