TECHNICAL FIELD OF THE INVENTION
The present invention relates to a receiver structure of a mobile phone, and more particularly to a receiver structure of a mobile phone that is easy to receive.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a receiving unit structure of a mobile phone includes a receiving speaker provided inside a housing and an opening provided on a surface of the housing for guiding a receiving sound from the receiving speaker outside the housing. In general, a user puts his / her ear on the opening and listens. However, since the opening is located on the plane of the housing and the user puts his / her ear on this plane to speak, there is a problem in that the position of the opening and the ear is difficult to determine and there is a feeling of anxiety. In addition, the problem that the ear hurts from the stress of the ears when talking for a long time, and the ears and the opening are less likely to come off due to vibration when talking while walking, and the volume and sound quality change, making it difficult to talk comfortably. In an environment with a lot of noise, there is a problem that noise enters the ear and the call quality is lowered.
[0003]
As a countermeasure against such a problem, it is conceivable to provide a projection having such a shape that the tip can be inserted into the ear canal of the user at the opening. For example, there is a conventional example shown in FIG. FIG. 4 is (a) a front view and (b) a partial sectional view of this conventional example.
[0004]
The structure of the mobile phone 40 is such that the speaker 42 connected from the inside of the housing 41 to the internal substrate 45 is tightly accommodated on the surface of the housing 41, and the tip of the speaker 42 enters the ear hole of the user. And a cover piece 44 for covering the entirety of the projection 43 from its tip. The projection 43 is large enough to accommodate the speaker 42 on the front side of the housing 41. And a circle 47 having a size sized to enter the ear canal into the ear hole of the user. The cover piece 44 has a portion which covers the projection 43 with sufficient contact and covers the ear hole at the tip, and at least the cover piece 44 between the cover piece 44 and the projection 43. Is formed of a soft elastic member that is easy to insert into the ear canal and does not damage the ear. Thus, the problem described above is solved by inserting the protruding portion 43 into the ear canal and receiving and listening. (For example, refer to Patent Document 1.)
Alternatively, there is another conventional example as shown in FIG. FIG. 5 is (a) a front view and (b) a side view of another conventional example. This mobile phone is attached to the earpiece of the mobile phone main body 50 so as to sandwich the sound collector 51. The conical sound collector 53 of the sound collector 51 has a sound collection hole 54 formed therein. In a state where the sound collector 51 is attached to the earpiece, the sound output from the earpiece is output from the front end opening through the sound hole 54 without being diffused outside. Since the sound collecting portion 53 is protruded and its tip is thin, the tip of the sound collecting portion is inserted into an ear during actual use. Therefore, the sound output from the opening at the distal end efficiently enters the ear. In addition, when the tip of the sound collecting unit 53 is inserted into the ear, surrounding noise is prevented from entering the ear. (For example, see Patent Document 2.)
