Description of the Related Art As a technique relating to a microphone mounting mechanism in recent years, for example, in the case where a button-shaped condenser microphone is built in the housing of an electronic device, a rubber piece supporting the microphone in a housed state is used. To
In general, the structure is such that it is attached in a state in which it is tightly press-fitted into a concave portion inside a cylindrical boss formed in the housing.
Further, in order to prevent the rubber piece from falling off easily, the rubber piece is also attached and fixed to the recess in the boss.

のである。However, in the prior art as described above, since the microphone is press-fitted and held in the cylindrical boss internal recess that rises directly from the inner surface of the housing, vibration from the outer surface of the housing is applied to the microphone. In a situation where the user directly grasps the casing with his / her fingers for recording, etc., the sound and vibration of rubbing between the fingers and the casing propagates through the casing member itself and is transmitted to the microphone body.
It will be recorded as noise. In addition, in order to prevent the rubber piece from easily falling off without bonding, it is necessary to press-fit it tightly into the concave portion inside the cylindrical boss and the housing, and at that time, between the rubber piece and It is difficult to assemble because friction occurs and the force required for assembly increases accordingly.

During the work of assembling into the cylindrical shape, it was not possible to confirm by visual inspection during the work whether or not the elastic member was applied to the inside of the housing over the entire inner surface of the concave portion of the cylindrical boss and firmly adhered. . Therefore, there are many cases in which a predetermined soundproofing or antivibration effect cannot be obtained and a recording result including internal noise is produced due to a slight gap caused by poor contact condition.

The microphone mounting mechanism as the first embodiment holds at least the elastic member 10 that covers the side surface (outer peripheral surface) of the substantially cylindrical (button-shaped) microphone 1 and the elastic member 10 that is fitted to hold the microphone 1. And holding members 22 and 26 that operate. This holding member 2
Reference numerals 2 and 26 are such that the bottom surface (back surface) of the microphone 1 and the mounting surface of the front housing 20 as an exterior member of the electronic device on which the holding members 22 and 26 are provided are substantially orthogonal to each other. The members 1 are provided in a pair on the inner surface of the front housing 20 so as to hold 1 on the peripheral surface via the elastic member 10. In addition, the holding members 22 and 26 have a cutout 24 at a part of their boundary.

Is formed as a non-slip member, so that it is possible to reliably support two places on the outer peripheral surface of the fitted elastic member 10.
However, in the case of this example, these holding members 22 and 26 extend vertically downward from the inner surface of the front casing 20, but a ring such as a wire having a substantially circular cross section that is separate from the front casing 20. It may be a member.

Following the a and 20b, the holding members 22 and 26 are provided in a left-right similar shape formed by projecting vertically downward, and are slightly separated by the notch 24. The front casing edges 28 and 29 formed to be higher and thicker than the casing surface 21 continue in the longitudinal direction, and also serve as the corner edges of the IC recorder.

To the left and right of the front casing surface 31 that rises 90 ° toward the front. An earphone jack hole 32 and an external microphone jack hole 34 are opened, and a microphone hole 35 having a radial slit is formed in the center.
The size of the ring shape formed by the holding members 22 and 26 (inner diameter) is set to be equal to or smaller than the outer diameter of the elastic member 10 when the microphone 1 is housed (details will be described later).

It is in the shape of a hat (hat) having a brim portion 11 that spreads outward so as to hit the inside of the body surface 31 (details will be described later).

る。The holding members 22, 26 which are similar to each other on the left and right sides with the notch 24 as a boundary exert a predetermined elastic force when slightly moving toward the center of the ring, so that the elastic member 10 is elastically moved by the elastic force. It can be firmly clamped from both sides. Therefore, in addition to the elasticity of the elastic member 10 itself, the microphone 1 is preferably held not only by the elastic force of the holding members 22 and 26 themselves to return to the desired positions and shapes. Moreover, the microphone 1 is replaced by the elastic member 1.
The elastic member 10 can be easily inserted even when it is housed in 0, and the elastic member 10 can be reliably held by the slightly projecting claws 23 and 27 formed on the opening side of the holding members 22 and 26.

By disposing the elastic member 10 that can be inserted into the holding members 22 and 26 and has an opening diameter φM larger than the ring inner diameter, the holding members 22 and 26 can be lightly attached when the elastic member 10 is attached. Since it can be attached by simply opening it, it is easy to assemble with almost no friction. In addition, since the elastic member 10 is held by the elasticity of the ring that tries to return to its original diameter after assembly, it does not fall off from there.

に振動を吸収できる。The size and shape such as the diameter of the elastic member 10 supporting the microphone 1 are adjusted according to the distances from the inner surfaces of the front housing 20 and the back housing 30 that house the microphone 1 inside. By appropriately determining α of the dimension (A + α), the brim portion 11 of the elastic member 10 can be pressed against the inside of the front housing surface 31 without being aware of it when assembling the two housings. Will be blocked and will not be recorded. The front case 20 is mostly covered with the decorative plate 40, and the microphone holding portions (holding members 22 and 26) provided inside the front case 20 do not have a rigid structure. Even if the finger directly touches it, it only makes indirect contact with the front case 20, and the vibration is absorbed by the microphone holding portion having a flexible structure, so that the vibration is hard to be transmitted to the microphone due to the suspension effect. Therefore, noise caused by the vibration is not mixed in the recorded content. In addition,
The casing surface 21 itself, which is thinly molded by molding or the like, also exhibits some elasticity as a whole, so that it can absorb vibration appropriately.
