Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a telephone with a built-in speaker.
More specifically, the present invention relates to a structure of a telephone that simultaneously holds a hook member and a speaker.

[Conventional technology]

Some recent telephones are equipped with a so-called speaker reception function that allows the user to receive the voice of the other party without using the handset, and for this reason, the telephone has a built-in speaker. In conventional telephones, a cylindrical built-in part is provided on the inner surface of the housing, and after a speaker is loaded into the built-in part, the rear peripheral edge of the speaker is locked with a bracket. In other words, in conventional telephones with a built-in speaker, the speaker is assembled as an independent structure.

[Problem that the invention attempts to solve]

Therefore, a bracket is required for assembling the speaker, and the number of man-hours required for assembling it is also long. Furthermore, recently, telephones are becoming smaller due to the electronicization of telephone circuit components, and there is a great demand for mechanical components to achieve this.

[Means for solving problems]

In view of these circumstances, the present invention comprises a hook member consisting of a handset receiver, a pair of arms, and a support shaft protruding from the inner surface of the tip of the arm, and a support member that swingably supports the hook member. consists of a pair of support walls with a U-shaped support groove at the tip,
A stud with a hole is provided in the center of each of these support walls for screwing a hook bracket that holds the hook member, and the hook bracket accommodates a speaker installed in a built-in part provided near the support part. The locking portion is integrally formed.

[Effect]

Therefore, the hook member, which is swingably assembled on the support wall, is held by the support shaft being locked by the hook bracket, and the hook bracket is also held by the locking part. This locks and holds the speakers at the same time.

〔Example〕

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

In the figure, reference numeral 1 denotes a synthetic resin housing, in which a rectangular hook guide hole 2 is provided in a part.
A pair of support walls 10 are integrally protruded from the inner surface of the housing near the guide hole 2 so as to face each other in parallel. These support walls 10, which constitute the support portion of the hook member 40 to be described later, have U-shaped support grooves 1 that are open at their tips and whose axes coincide with each other.
1 is provided, and furthermore, two ribs 12 that are spaced apart from each other in the width direction protrude from each opposing inner surface. The tips of these ribs 12 are located slightly inward from the tips of the support wall 10. A stud 20 is integrally erected on the inner surface of the housing at the center of the support wall 10, and a blind hole 21 is provided in the stud 20.
are provided, and ribs 22 are provided on their peripheral surfaces so as to extend close to the inner surface of the support wall 10, and dowels 23 are provided protruding from the tips of the ribs 22. In addition, the supporting wall 10
On the other hand, a speaker assembly portion 30 is provided on the inner surface of the casing on the side opposite to the hook guide hole 2.
This built-in part 30 consists entirely of a cylindrical vertical wall,
A large number of sound emitting slits 31 are provided in the casing surrounded by the standing wall, and a notch 32 is provided in the supporting wall side portion of the standing wall. A speaker 3 is connected to this built-in portion 30 via a cushion 36a.
5 is loaded.

Hook member 4 molded from synthetic resin material
0 includes a block-shaped handset receiving part 41 that penetrates the guide hole 2 and is exposed to the outside, a pair of arm parts 42 that are integrally protruded from both sides of the block-shaped handset receiving part 41, and axes of the arms from the inner surface of the distal ends of these arm parts. It consists of a supporting shaft portion 43 that is protruded so as to coincide with each other, and an actuating portion 44 that is protruded from the bottom surface of the receiving portion. The distance between the arm portions 42 is slightly larger than the distance between the support walls 10, and the length of the arm portions 42 is approximately equal to the distance from the support groove 11 to the guide hole 2. Of course, the outer dimensions of the handset receiving portion 41 are made slightly smaller than the hole dimensions of the guide hole 2. Therefore, the support shaft portion 4
3 fitted into the support groove 11, the hook member 40 is
The arm portion 42 extends toward the guide hole along the outer surface of the support wall 10, and the receiving portion 41 thereof is positioned corresponding to the guide hole 2. The hook portion 40 assembled to the support portion is held by a hook bracket 50. The hook bracket 50 consists of a plate-shaped base 51 and a substantially C-shaped locking part 53 integrally projecting from one side edge of the base through an arm 52. The longitudinal width of the base 51 is approximately equal to the spacing between the supporting walls 10, and the thickness thereof is approximately equal to the height difference between the tip of the supporting wall and the tip of the rib 12. The base 51 also has a hole 5 corresponding to the stud 20.
4 and small holes 55 are provided corresponding to the dowels 23 of the ribs 22, respectively. The hook bracket 50 is secured onto the stud 20 by screws 56. As described above, when the hook member 40 is assembled to the support part, the support shaft part 43 of the hook member 40 is fitted into the U-shaped support groove 11 from the outside of the support wall 10 and projects inward. Therefore, when the hook member 40 is assembled, the hook bracket 5
0 onto the stud 20, the opening of the support groove 11 is closed, and the hook member 40 is swingably held on the support portion. In addition, by locating the arm portion 42 of the hook member 40 outward with respect to the support wall 10, in other words, by configuring the support shaft portion 43 to protrude inward of the support groove 11, the side direction Since there is no need to take into consideration the possibility that the ribs 12 may come off, the shape of the base 51 of the hook bracket 50 that holds this supporting portion can be made into a simple plate shape.
Since it is received on the end face of the rotor, a special locking structure is not required. Further, the hook member 40, which is swingably assembled to the support portion in this way, has its operating portion 44 engaged with a hook switch (not shown), and is pushed upward by the hook switch. The head of the band set receiving part 41 protrudes from the guide hole 2 and is exposed.

Hook bracket 50 also acts as a retainer for speaker 35. That is, the locking portion 53 of the hook bracket 50 fixed on the stud 20 by the screw 56 extends into the speaker assembly portion 30 through the notch 32, and the speaker incorporated therein is 35 engages with the flange circumferential surface 36. Therefore, the speaker 35 is connected to the locking portion 5
3 to the inner surface of the housing 1, thereby firmly fixing it in the built-in portion 31.

[Effect of idea]

As explained in detail above, according to the present invention,
The hook member is firmly and swingably supported by a single hook bracket on the support portion, and this hook bracket simultaneously functions as a member for holding the speaker. Therefore, the number of parts and the number of assembly steps are reduced, and the structure becomes simpler and more compact, resulting in extremely large practical effects.
