  The present invention relates to an electroacoustic transducer with a holder incorporated in an electronic device, for example, a small microphone with a holder, a receiver with a holder, and a sounder with a holder incorporated into a portable electronic device such as a personal computer, a mobile phone, and a pager.

Conventionally, as a small microphone incorporated in a mobile phone or the like, for example, Patent Document 1 discloses a microphone holder having a structure in which a microphone is surrounded by rubber except for sound holes in order to prevent generation of howling and vibration noise. Japanese Patent No. 3000742 (hereinafter referred to as Patent Document 2) discloses a mounting method in which jumper wires of a microphone unit and a substrate are connected to each other, and the mounting posture of the microphone unit is adjusted around the jumper wire. ing.
Japanese Patent Laid-Open No. 10-233828 Patent No. 3000742

However, in the conventional techniques represented by the above-mentioned Patent Documents 1 and 2, after the microphone holder for storing the microphone is formed, the microphone holder is adjusted so that the posture of the microphone can be set vertically or horizontally, for example. There is no disclosure of the technology that makes it possible. Accordingly, a microphone holder dedicated to the vertical installation is required for the vertical installation, and a microphone holder dedicated to the horizontal installation is required for the horizontal installation.
Therefore, for example, a microphone with a general-purpose holder that can cope with a change in mounting posture is formed by forming a microphone that responds to various posture changes in accordance with a change in the mounting posture of the microphone accompanying a change in the model of a mobile phone or the like. desired.

  This invention is invented in view of the above-mentioned problem, and it aims at providing the general-purpose electroacoustic transducer with a holder which responds to various attitude | position changes.

An electroacoustic transducer having a plurality of terminal electrodes;
A block-shaped holder having a plurality of surfaces, in which a housing chamber containing the electroacoustic transducer having an opening on one surface is formed;
A plurality of connection electrodes provided on the bottom wall surface of the storage chamber and connected to the plurality of terminal electrodes, respectively;
A plurality of mounting electrodes provided corresponding to the plurality of connection electrodes on each of the plurality of surfaces of the holder;
A wiring portion that is provided in the holder and electrically connects each of the connection electrodes and the corresponding mounting electrodes on the plurality of surfaces;
Are included.

  According to the present invention, since a plurality of mounting electrodes connected to a plurality of terminal electrodes of the electroacoustic transducer are provided on each of at least two surfaces of the holder, either surface can be mounted on an electronic device. As a result, a general-purpose microphone that can respond to various posture changes can be obtained.

[First embodiment]
1A, 1B and 1C are perspective views of holders of a microphone with a holder (hereinafter referred to as a microphone assembly), which is a first embodiment of an electroacoustic transducer with a holder according to the present invention, as seen from different directions. The holder 10 is generally formed in a block shape from a heat-resistant elastic body such as silicon rubber, and is opposed to the front (upper surface) 11a and the rear surface 11b facing each other in parallel with each other, perpendicular to the front and back surfaces, and facing each other in parallel. Side surfaces 11c and 11d, front surface, back surface, and front surface 11e and rear surface 11f that are perpendicular to the side surfaces and parallel to each other.

  In this embodiment, in order to indicate the orientation of the holder 10, slopes 11g and 11h are formed so as to cut out ridges where the side surfaces 11c and 11d intersect the tip surface 11e. By forming the holder 10 from a heat-resistant resin, a soldering process can be performed in a reflow tank. For example, soldering by a reflow process can be performed between a terminal electrode 27 and a connection electrode 8 of a microphone body 20 described later as an electroacoustic transducer. It becomes possible. Further, the holder 10 is made of an elastic body, which can be deformed according to the storage space for mounting the electroacoustic transducer on the electronic device. Further, as will be described later, the front surface of the microphone body 20 and the microphone assembly. This is because, for example, the adhesiveness of sealing the sound hole space formed between the inner wall surface of the housing of the mobile phone and the sealing portion 5 of the holder 10 can be improved. Moreover, if it is an elastic body which has insulation, such as silicon rubber, the insulation between wiring parts or between attachment electrodes, and between the microphone body and other parts can be obtained.

  The holder 10 has a cylindrical storage chamber 3 having an opening on the front surface 11a and reaching the vicinity of the back surface 11b in accordance with the shape of the microphone main body 20 (here, a flat cylindrical shape) as shown in FIGS. 2A and 2B, for example. is doing. A hole 3 a that is concentric with the storage chamber 3 and has a diameter smaller than that of the microphone body 20 is formed in the bottom wall 4 on the back surface 11 b side of the storage chamber 3. Four connection electrodes 8E are attached to the bottom wall 4 so as to enter the center of the hole 3a at equal angular intervals around the hole 3a. An annular sealing portion 5 is formed on the front surface 11a of the holder 10 so as to surround the housing chamber 3. The hole 3a is used, for example, for connection work between the connection electrode 8E and a terminal electrode of the microphone body 20 described later.

  A microphone body 20 shown in FIGS. 2A and 2B is stored in the storage chamber 3. The microphone body 20 includes a cylindrical case 21 with a front surface 21a closed and a substrate 25 that is fitted and inserted so as to close the back surface. The substrate 25 is formed in the case 21 by a caulking portion 21F at the lower end of the case 21. It is fixed to. In this case, the front surface 21a in which the sound hole 26 of the microphone body 20 is formed is substantially flush with the front surface 11a of the holder 10, and the substrate 25 on which the terminal electrode 27E of the microphone body 20 is formed is positioned on the bottom wall 4 side. It is stored in. The microphone body 20 shown in FIGS. 2A and 2B has four terminal electrodes 27E1, 27E2, 27E3, and 27E4. With the digital electret condenser microphone in mind, the terminal electrode 27E has a power source, a ground, an output signal, Four terminals for the clock. In the case of a conventional analog electret condenser microphone, the number of electrodes is sufficient with respect to the number of terminals such as three terminals of power supply, ground and output signal, or two terminals of ground and output signal.

  Returning to FIG. 1, a plurality (four in the figure) of connection electrodes 8 </ b> E coming into contact with the terminal electrodes 27 </ b> E of the microphone body 20 from the bottom wall 4 in the state where the microphone body 20 is housed in the housing chamber 3. The connection electrodes 8E are routed by the plurality of wiring portions 8L and connected to the corresponding ones of the plurality of mounting electrodes 8T. That is, each connection electrode 8E is connected to four mounting electrodes 8T exposed on the front surface 11a, the back surface 11b, and the rear end surface 11f by corresponding wiring portions 8L (see FIG. 3 for details of the wiring portions). Reference later).

However, the portion of the wiring portion 8L is actually an insert. It will be in the state embedded in the silicone rubber which forms the holder 10 by shaping | molding. Therefore, even if the holder 10 having elasticity undergoes some elastic deformation, the wiring portion does not come off.

  FIG. 3 illustrates a connection electrode 8E formed as an integral member by punching and bending, a wiring portion 8L, and a plurality of mounting electrodes 8T formed for each connection electrode 8E. 3 and FIGS. 4A to 5E and FIGS. 5A and B, the four connection electrodes 8E are represented by 8E1, 8E2, 8E3, and 8E4, respectively, and the four wiring portions 8L are represented by 8L1, 8L2, 8L3, and 8L4, respectively. The plurality of mounting electrodes 8T connected to the respective wiring portions are represented by 8Ta1, 8Tb1, 8Tf1; 8Ta2, 8Tb2, 8Tf2, 8Ta3, 8Tb3, 8Tf3; 8Ta4, 8Tb4, 8Tf4.

  1A and 1B, two wiring portions 8L3 and 8L4 are bridged from the rear end surface 11f to the front end surface 11e on the back surface 11b of the holder 10, and the wiring portions 8L3 and 8L4 rise from the front end surface 11e to the front surface. Up to 11a. Further, two wiring portions 8L1 and 8L2 are bridged on the back surface 11b of the holder 10 from the edge of the bottom wall 4 to the rear end surface 11f. The wiring portions 8L1 and 8L2 rise from the rear end surface 11f to the front surface 11a. Has reached. The wiring portion 8L4 is formed with bent electrodes 8Tf4, 8Ta4, 8Tb4 at both ends and in the middle, and the wiring portion 8L3 is formed with bent electrodes 8Tf3, 8Ta3, 8Tb3 at both ends and in the middle. Further, the wiring portion 8L1 is formed with bending electrodes 8Ta1, 8Tf1, and 8Tb1 at two ends and halfway, and the wiring portion 8L2 has the mounting electrodes 8Ta2, 8Tf2, and 8Tb2 at two ends and halfway. Is formed by bending.

  As a result, the mounting electrodes 8Ta4, 8Ta3, 8Ta1, and 8Ta2 are positioned on the front surface 11a of the holder 10, and the mounting electrodes 8Tf4, 8Tf3, 8Tf1, and 8Tf2 are positioned on the rear end surface 11f. In this case, the mounting electrodes 8Tb4, 8Tb3, 8Tb1, and 8Tb2 are located. Further, the mounting electrodes 8Ta4 and 8Ta1, 8Ta3 and 8Ta2, 8Tb4 and 8Tb1, and 8Tb3 and 8Tb2 are positioned opposite to each other on the front end surface 11e side and the rear end surface 11f side. Here, the mounting electrodes 8Ta1, 8Ta2, 8Tb1, 8Tb2 are arranged on the rear end face 11f side, the mounting electrodes 8Ta4, 8Ta3, 8Tb4, 8Tb3 are arranged on the front end face 11e side, and the mounting electrodes 8Tf1, 8Tf2 are arranged on the front face 11a side The reason why the mounting electrodes 8Tf4 and 8Tf3 are arranged on the back side is to secure the arrangement of the holder 10 by arranging the mounting electrodes widely apart from each other. Therefore, if stability of the arrangement of the holder 10 is obtained, for example, the mounting electrodes 8Tf1 and 8Tf2 may be formed adjacent to the mounting electrodes 8Tb1 and 8Tb2 so as to be aligned with the mounting electrodes 8Tf4 and 8Tf3. Further, the mounting electrodes 8Tb4 and 8Tb3 may be formed adjacent to the mounting electrodes 8Tf4 and 8Tf3 so as to be aligned with the mounting electrodes 8Tb1 and 8Tb2.

Further, the wiring portions 8L4, 8L3, 8L1, and 8L2 are branched from the middle of the wiring portions 8L4 and 8L3 and at the ends of the wiring portions 8L1 and 8L2, and rise from the back surface 11b of the holder 10 along the edge of the hole 3a. The front surface of the bottom wall 4 is connected to the connection electrodes 8E4, 8E3, 8E1, and 8E2.

  4A to 4E, the back end surface 11f of the holder 10 has some unevenness on the surface thereof. This is because, with the holder 10 placed vertically on a circuit board (not shown), the wiring portions 8L1, 8L2 and the mounting electrodes 8Tf3 are provided so that the holder 10 can be stably upright on the rear end face 11f with respect to the circuit board. , 8Tf4 other than the convex part 11fP. Further, as clearly shown in the top view of FIG. 4B (and also see FIG. 5B), a convex stepped portion 4a is formed on the inner peripheral edge on the front surface side of the bottom wall 4, for example, a microphone like an electret condenser microphone. The terminal electrodes 27E1 to 27E4 of the microphone body 20 are connected to the connection electrodes 8E1 to 8E4 by the convex stepped portion 4a having a thickness equal to or greater than the thickness of the caulking portion 21F (see FIG. 2B) of the case 21 of the body 20, and the bottom wall 4 is simultaneously formed. The microphone body 20 is securely placed on

That is, the back surface 11b of the holder 10 of the microphone assembly 32 is placed on the circuit board 31, and the mounting electrodes 8Tb1, 8Tb2, 8Tb3, 8Tb4 of the holder 10 are soldered to the electrodes 34E1, 34E2, 34E3, 34E4 provided on the circuit board 31. Attach. In this case, the inner wall surface of the housing 33 presses the sealing portion 5 of the holder 10 with the housing 33 of the mobile phone 30 placed on the circuit board 31. Since the sealing part 5 has elasticity, the sealing part 5 is in close contact with the inner wall surface of the housing 33, and the acoustic space formed between the inner wall surface of the housing and the front surface 21a of the microphone body 20 is sealed.

  7A, 7B, and 7C show the case where the microphone assembly 32 is mounted on the circuit board 31 of the mobile phone 30 in a so-called vertical position. That is, the rear end surface 11f of the holder 10 of the microphone assembly 32 is placed on the circuit board 31, and the mounting electrodes 8Tf1, 8Tf2, 8Tf3, 8Tf4 of the holder 10 are electrodes 34E1, 34E2, 34E3, 34E4 formed on the circuit board 31. Solder to. In this case, the side inner wall surface of the housing 33 presses the sealing portion 5 of the holder 10 with the housing 33 of the mobile phone 30 covered with the circuit board 31, and the space between the front surface 21 a of the microphone body 20 and the side wall surface is reduced. The acoustic space is sealed. In addition, in this vertically placed state, there is also a feature that it is hardly affected by vibration from the circuit board 31.

  8A to 8D show the microphone assembly 32 attached from the back side of the circuit board 31 of the mobile phone 30 and the sealing portion 5 of the holder 10 being closely inserted into the round hole 31a of the circuit board 31. The mounting electrodes 8Ta1 to 8Ta4 of the holder 10 are soldered to the electrodes 34E1 to 34E4 provided on the back surface of the circuit board 31. The sealing part 5 of the holder 10 is pressed and fixed to the back surface of the circuit board 31. The keypad 35 also has a sealing function in a state where the housing 33 of the mobile phone 30 is covered with the circuit board 31. In the mounting structure of the microphone assembly 32, the microphone assembly 32 is located on the back side of the circuit board 31, so that the housing space can be effectively used.

[Second Embodiment]
In the description so far, an example has been given in which silicon rubber is used with the holder 10 as a massive heat-resistant elastic body, but a heat-resistant resin may be used instead of the heat-resistant elastic body. In this case, the sealing part 5 is desirably an elastic body in terms of a function of sealing the sound hole space. For this reason, FIG. 10 illustrates a structure in which the holder 10 is formed separately from the sealing portion 5 and the other portion (herein referred to as the storage body 10 ′), and these are connected and integrated. That is, FIG. 10 shows a structure in which a sealing portion 5 having a collar portion 5a made of, for example, silicon rubber is arranged on the front surface of a storage body 10 ′ made of a heat-resistant resin such as polybutylene terephthalanol or liquid crystal polymer. . 11A and 11B show an exploded perspective view and an exploded front view of the holder 10 of FIG. In the example of FIGS. 11A and 11B, the sealing portion 5 including the flange portion 5a has a size that fits into the storage chamber 3 of the storage main body 10 ′. In other words, the sealing portion 5 is pasted on the front surface of the microphone main body 20. Have With the sealing part 5 attached to the microphone body 20, the sealing part 5 is arranged so as to surround the sound hole 26 of the microphone body 20. Here, an example in which the sealing part 5 is attached to the microphone body 20 is shown, but the sealing part 5 may be attached to the front surface 11a of the storage body 10 ′ so as to surround the storage chamber 3.
[Third embodiment]
12A to 12D show a third embodiment. In this embodiment, a sound hole 26 is formed in the substrate 25 on which the terminal electrode 27E of the microphone body 20 is formed. 3 and 4A to E, the mounting electrodes 8Ta1 to 8Ta4 on the front surface 11a side are omitted, the mounting electrodes 8Tf1 and 8Tf2 are arranged on the rear surface 11b side on the rear end surface 11f, and the mounting electrodes 8Tf3, This is the same as the structure in which 8Tf4 is arranged on the front surface 11a side. Accordingly, the terminal electrode 27E and the sound hole 26 of the microphone body 20 are located on the back surface 11b side of the holder 10. In the example of FIGS. 12A to 12D, the sealing portion 5 may be formed around the storage chamber 3 on the back side of the holder 10. However, when the holder 10 is formed of an elastic body such as silicon rubber, the back surface 11b is pressed against the surface of the wiring board to which the microphone assembly is attached without forming a sealing portion on the back surface 11b of the holder 10. As a result, the sound hole space formed in front of the substrate 25 inside the hole 3a can be sealed.

In the description so far, an example in which a sealing portion is provided to prevent noise from wrapping around has been shown, but when using a low-hardness material as the material of the elastic body used for the holder 10, even if the sealing portion is not provided, The sealing function can be achieved by pressing the surface of the holder 10 against the surface of the wiring board to which the microphone is attached.
Further, in the present invention, automatic mounting is possible by connecting a large number of holders and sequentially mounting the microphone body, that is, by introducing a so-called tape and reel. It is also possible to mount a large number of microphone assemblies 32 on a tape and reel, and to automatically mount the microphone assemblies 32 sequentially on a circuit board such as a mobile phone.

Although the example of the microphone with a holder described above has been described for a mobile phone, it can be applied to a small information communication device such as a PDA, a digital camera, or the like.
