Therefore, the electronic device can be downsized and the weight of the electronic device can be reduced. As a result, the electronic devices can be sufficiently arranged even in a limited space such as the interior of a car.
- the sound guide portion also serves as a display portion fixing function for fixing the display portion
- the sound guide path is formed using the existing constituent members originally required for the electronic device. Can be formed.
- the sound guide portion is formed using an independent member different from the fixing portion for fixing the display portion.
- the sound output from the speakers can be used not only through the housing but also through the sound guide path. Since the display unit can resonate, the sound quality of the sound output from the speaker can be improved.
- the sound guide path is formed by using existing constituent members originally required for the electronic device. Can be made. As a result, it is possible to prevent the assembly man-hours and weight of the electronic device from increasing as compared with the case where the sound guide portion is formed using another independent member for fixing the speaker.
- the sound guide portion is made of a material that does not transmit light
- the sound guide portion particularly serves as a display portion fixing function for fixing the display portion. Even in this case, it is possible to prevent light with a strong display portion from passing through the sound guide portion and leaking outside the housing.
- FIG. 1 is a front view of an electronic device according to an embodiment of the present invention.
- FIG. 2 is a configuration diagram in which a rear (rear) side force is also seen in a state in which the rear portion of the casing constituting the electronic device according to the embodiment of the present invention is removed.
- FIG. 3 is a longitudinal sectional view of an electronic apparatus according to an embodiment of the present invention.
- the electronic device of the present invention can be widely applied to, for example, a liquid crystal television and a car navigation system.
- the electronic device 10 includes a box-shaped housing 12 that is an outer side.
- the housing 12 is configured by combining a housing front portion 12A located on the front (front surface) side and a housing rear portion 12B located on the rear (back surface) side. Front of housing front 12A A support portion 14 is formed on the side (front surface) side, and a touch panel portion 16 is disposed on the rear (back surface) side of the support portion 14. An operation unit 18 is provided on the front (front surface) side of the housing 12 and on the lower side of the touch panel unit 16. The operation unit 18 is provided with input buttons 18A and the like necessary for operation. In addition, on both the left and right sides of the operation unit 18, there are provided slit portions 18B that form entrances of a sound guide duct (sound guide portion) 24 described later.
- a liquid crystal display unit (display unit) 20 that displays predetermined information is disposed inside the front portion 12A of the casing and on the rear (back side) side of the touch panel unit 16.
- the liquid crystal display unit 20 includes, together with the touch panel unit 16, a claw portion 22 formed in the front portion 12A of the housing, an upper sound guide duct portion 24A constituting a sound guide duct 24 described later, and the support portion 14 described above. By this, the positioning is fixed inside the housing front part 12A.
- each of the sound guide data 24 includes an upper sound guide duct portion 24A that is attached to the housing front portion 12A and positions and fixes the liquid crystal display portion 20, and a lower sound guide duct portion 24B that is attached to the housing front portion 12A. It is configured as a space part closed by. As a result, sound generated from a speaker 28 described later is output from the slit portion 18B that does not leak to the outside of the housing 12. Further, the upper sound guide duct portion 24A and the lower sound guide duct portion 24B are made of a material that does not transmit light such as black plastic resin.
- each sound guide duct 24 is formed to extend linearly from the front surface side of each speaker 28 toward the front surface side of the housing front portion 12A.
- the front end portion of each upper sound guide duct portion 24A and the front end portion of each lower sound guide duct portion 24B are connected to each slit portion 18B.
- Each speaker 28 is provided in the front part 12A of the casing and on the back side of the liquid crystal display unit 20 so that a part thereof protrudes downward from the liquid crystal display unit 20.
- the sound guide duct 24 has a display unit fixing function for fixing the liquid crystal display unit 20, and also a speaker force fixing for fixing each speaker 28. It is configured to combine functions.
- each speaker 28 is provided inside the housing front part 12A and on the back side of the liquid crystal display part 20, and a part thereof protrudes downward from the liquid crystal display part 20.
- each sound guide duct 24 is formed in a straight line extending from the surface side of each speaker 28 toward the surface side of the front portion 12A of the housing, so that each sound guide duct 24 is not bent. . For this reason, even when high-frequency sound is generated from each speaker 28, it can be output to the outside of the housing 12 without deteriorating the sound quality. Further, since it is not necessary to arrange each speaker 28 on the surface of the housing 12 and outside the liquid crystal display unit 20, the electronic device 10 can be downsized and the weight of the electronic device 10 can be reduced. Can do. As a result, the electronic device 10 can be sufficiently disposed even in a limited space such as the interior of a car.
- the sound guide duct 24 since the sound guide duct 24 also serves as a display unit fixing function for fixing the liquid crystal display unit 20, the sound guide duct 24 should be formed by using existing components that are originally necessary for the electronic device 10. Can do. As a result, it is possible to prevent an increase in the number of assembly steps and the weight of the electronic device 10 as compared to the case where the sound guide duct is formed using an independent member different from the fixing portion for fixing the liquid crystal display portion 20. .
- the sound output from the speaker 28 can resonate the liquid crystal display unit 20 not only through the housing 12 but also through the sound guide duct 24, so that the sound quality of the sound output from the speaker 28 can be improved. .
- each sound guide duct 24 also has a speaker fixing function for fixing each speaker 28, the sound guide duct 24 is formed by using existing constituent members originally required for the electronic device 10. Can be made. As a result, it is possible to prevent an increase in assembly man-hours and weight of the electronic device 10 as compared with the case where another independent member for fixing the speaker 28 is used to form the sound guide portion.
- the sound guide duct 24 is made of a material that does not transmit light (in this embodiment, a black plastic resin), the sound guide duct 24 particularly fixes the liquid crystal display unit 20. Even in the case of a configuration that also serves as a part fixing function, it is possible to prevent light from the liquid crystal display unit 20 and the operation unit 18 from passing through the sound guide duct 24 and leaking from the slit unit 18B to the outside of the housing 12.
