Abstract

(57) [Abstract] [Purpose] In a handset type cordless telephone with a structure in which the sound output hole of the speaker is easily blocked when placed on the back, a reduction in the volume of the speaker can be prevented with a simple configuration. To provide the speaker sound emitting part structure as described above at a low cost. [Structure] A protrusion 8 is provided in the vicinity of a speaker sound output hole 6 for ringing sound provided on the back surface of the body case 1, and even when the body case 1 is placed on its back, it is placed on the rear surface of the body case 1. It is characterized in that a gap is secured between the contact surface and the speaker sound output hole 6 so as not to be blocked.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a speaker sound emitting structure for a cordless telephone handset, a mobile phone, or the like for receiving a ringing sound or a speaker. In particular, a speaker sound emitting hole is provided on the back of a handset type body case. The present invention relates to the structure of a speaker sound emitting part in a type of telephone set.

[0002]

[Prior art]

 For cordless handset handsets or mobile phones, when a speaker is provided for ringing when receiving an incoming call and a speaker for listening without holding the machine body, the sound emission hole should be provided on the back of the machine case. However, due to design considerations, the back of the machine case may be flat, and even if the back is not flat, sound output holes are provided near the center of gravity of the machine. There is a case.

[0003]

[Problems to be solved by the device]

 In the above conventional structure, when the aircraft is placed on its back, i.e., with its back facing downwards, when it is not in use after the end of a call, the sound output hole is closed, and when the aircraft case is closed. Even if the back surface is not flat, if the sound output hole is provided near the center of gravity of the aircraft, the sound output hole may be blocked when the back surface is placed downward. However, there is a drawback that the volume of the speaker is significantly reduced.

Therefore, an object of the present invention is to prevent a decrease in the volume of the speaker with a simple structure in a telephone having a structure in which the sound emission hole of the speaker is easily closed when placed on the back. The purpose is to provide a speaker sound emitting structure for a handset-type cordless telephone at a low cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that, in a handset type cordless telephone, a protrusion is provided in the vicinity of a speaker sound emission hole for a ringing sound provided on the back surface of the body case. is there.

[0006]

[Action]

 Even when the sound output hole part is placed downward on a desk or the like, the tip of the protrusion provided near the sound output hole and the top surface of the desk contact the back surface of the machine case and the contact surface such as the top surface of the desk. Since the gap is kept between the sound emitting holes, the sound emitting hole is not closed, and thus the volume reduction of the speaker is prevented.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

As a handset type cordless telephone to which the speaker sound emitting unit structure of the present invention is applied, for example, as shown in FIGS. 1 and 2, a body case having a slender shape with a central portion suitable for grasping and a flat back surface 1 is equipped with an electric part for transmission and reception inside, and a transmitter part 2 and a receiver part 3 are separately provided inside the front parts near both ends, and the front part near the center is for dialing. Also, the operation portion 5 in which the pushbuttons 4 and 4 for the function are arranged side by side is provided, and the sound output holes 6 and 6 are formed on the rear surface of the body case 1 near the upper end where the earpiece 3 is located. A cordless handset of the type having a speaker 7 for receiving a ringing tone when receiving an incoming call and a speaker 7 for receiving without holding the body is adopted.

As a special configuration of the present invention for a cordless telephone handset of the above type, as shown in detail in FIGS. 1 and 2, for example, a sound emission hole 6 is imitated on the rear surface of the body case 1. A plurality of shaped protrusions 8 and 8 are provided in the vicinity of the sound output holes 6 and 6. The number of the protrusions 8 may be one, but a plurality of protrusions 8 and 8 are provided at appropriate intervals in the lateral direction of the body case 1. It is desirable to provide one unit so that the body case 1 can be stably placed on the back.

[0010]

[Effect of device]

 As described above, according to the present invention, by providing the protrusion in the vicinity of the speaker sound output hole provided on the rear surface of the body case, the rear surface of the body case can be kept even when the body is placed on its back. Since the speaker is not brought into close contact with the contact surface to be placed, the sound output hole of the speaker is not closed, and therefore, the volume reduction of the speaker can be easily prevented by a remarkably simple structure.
