この発明は、携帯型電子機器における小型スピーカ実装構造及び該構造を備えた携帯型電子機器に係り、例えば、折畳み型の携帯電話機等の携帯型電子機器の筐体の側面から音声が放射されるように小型スピーカが配置された携帯型電子機器における小型スピーカ実装構造及び該構造を備えた携帯型電子機器に関する。   The present invention relates to a small speaker mounting structure in a portable electronic device and a portable electronic device having the structure. For example, sound is radiated from a side surface of a casing of a portable electronic device such as a folding cellular phone. The present invention relates to a small speaker mounting structure in a portable electronic device in which small speakers are arranged and a portable electronic device having the structure.

従来より、携帯型の電子機器としての携帯電話機は、例えば、着信時に、リンガ発生部(音声出力部)からの着信音(呼出音)の出力や、着信通知ランプの点滅、バイブレータの振動等によって、着信したことをユーザに知らせるように構成されている。
このような折畳型の携帯電話機では、折畳時にユーザが着信音を確実に聴き取れるように、筐体の背面側(折畳時には外面側となる側)に、リンガ発生部を構成するスピーカを配置して、背面側からスピーカ音を放射されるように構成したり(例えば、特許文献1参照。)、また、携帯電話機を机上等に載置した状態でも聴き取れるように、筐体の側面部にスピーカ音を放射させる開口(音孔)を設けるようにしている(例えば、特許文献2参照。)。
着信時には、このスピーカが着信音を発生し、ユーザがこれを聞くことによって着信を知り、この後、筐体を開いて、所定の操作を行うこととなる。
2. Description of the Related Art Conventionally, a mobile phone as a portable electronic device has, for example, an output of a ring tone (ringing sound) from a ringer generation unit (voice output unit), blinking of an incoming notification lamp, vibration of a vibrator, etc. The system is configured to notify the user that an incoming call has been received.
In such a foldable mobile phone, a speaker that forms a ringer generating part on the rear side of the casing (the side that is the outer surface side when folded) so that the user can reliably hear the ringtone when folded. So that the speaker sound can be emitted from the back side (see, for example, Patent Document 1), or the mobile phone can be heard even when placed on a desk or the like. An opening (sound hole) for radiating speaker sound is provided on the side surface (see, for example, Patent Document 2).
When an incoming call is received, this speaker generates a ring tone, and the user hears this to know the incoming call. Thereafter, the casing is opened and a predetermined operation is performed.

筐体の側面部からスピーカ音を放射させる場合には、図11及び図12に示すように、筐体の側面部101の内部側に、開口(音孔)101aに対応する位置にスピーカ102を嵌着状態で収納するための箱状の収納部103を設け、収納部103内に、クッション104を音を放出する側(下面側)に貼り付けた状態でスピーカ102を嵌め込み、筐体内に各種部品を実装して組み立てた時に、スピーカ102が押圧される際に、クッション104が押されて変形することによって、密着されて音洩れを防止するようにしていた。
しかしながら、開口101aがスピーカ102の配置位置と高さ方向に沿ってずれた位置に設けられているので、筐体が厚くなってしまい、携帯電話機の薄型化の妨げとなってしまうという問題があった。
When the speaker sound is radiated from the side surface portion of the housing, as shown in FIGS. 11 and 12, the speaker 102 is placed inside the side surface portion 101 of the housing at a position corresponding to the opening (sound hole) 101a. A box-shaped storage portion 103 is provided for storage in a fitted state, and the speaker 102 is fitted into the storage portion 103 with the cushion 104 attached to the sound emitting side (lower surface side). When the components are mounted and assembled, when the speaker 102 is pressed, the cushion 104 is pressed and deformed, thereby being brought into close contact and preventing sound leakage.
However, since the opening 101a is provided at a position shifted in the height direction from the position where the speaker 102 is arranged, there is a problem that the casing becomes thick and obstructs the thinning of the mobile phone. It was.

このため、スピーカの位置と、筐体の側面部の開口の位置とを重なるようにして、スピーカの音を放出する側を筐体の側面部の開口に対向させて、スピーカを配置する方法が提案されている。
例えば、図13に示すように、筐体の側面部201の内部側に、開口201aに対応する位置にスピーカ202を嵌着状態で収納するためのの箱状の収納部203を設け、収納部203内に、クッション204を音を放出する側に貼り付けた状態でスピーカ202を嵌め込み、かつ、スピーカ202の背面側(音を放出する側に背向する側)の収納部203の壁部との間に、板状の圧入部材205を圧入して、クッション204が側面部201側に押されて変形することによって、密着されて音洩れの防止が可能となる。
ここで、圧入部材205には、収納部203に設けられた係止孔203aに係止される爪部205aが設けられ、圧入部材205を圧入した際に、圧入部材205が所定の位置で、係着されることとなる。
For this reason, there is a method in which the position of the speaker and the position of the opening on the side surface portion of the housing are overlapped, and the speaker is disposed with the sound emitting side of the speaker facing the opening on the side surface portion of the housing. Proposed.
For example, as shown in FIG. 13, a box-shaped storage unit 203 for storing the speaker 202 in a fitted state at a position corresponding to the opening 201a is provided on the inner side of the side surface unit 201 of the housing. The speaker 202 is fitted in a state where the cushion 204 is attached to the sound emitting side in the 203, and the wall portion of the storage portion 203 on the back side of the speaker 202 (the side facing away from the sound emitting side) In the meantime, the plate-like press-fitting member 205 is press-fitted, and the cushion 204 is pushed and deformed to the side surface part 201 side, so that it is brought into close contact and sound leakage can be prevented.
Here, the press-fitting member 205 is provided with a claw portion 205a that is locked to a locking hole 203a provided in the storage unit 203, and when the press-fitting member 205 is press-fitted, the press-fitting member 205 is in a predetermined position. Will be attached.

また、図14(a)に示すように、筐体の側面部301の内部側に、開口301aに対応する位置にスピーカ302を嵌着状態で収納するためのの箱状の収納部303を設け、同図(b)に示すように、収納部303内に、クッション304を音を放出する側に貼り付けた状態でスピーカ302を嵌め込み、かつ、スピーカ302の背面側(音を放出する側に背向する側)の収納部303の壁部との間に、圧入部材305を圧入し、同図(c)に示すように、クッション304が側面部301側に押されて変形することによって、密着されて音洩れの防止が可能となる。   Further, as shown in FIG. 14 (a), a box-shaped storage portion 303 for storing the speaker 302 in a fitted state at a position corresponding to the opening 301a is provided on the inner side of the side surface portion 301 of the housing. As shown in FIG. 5B, the speaker 302 is fitted in the storage portion 303 with the cushion 304 attached to the sound emitting side, and the back side of the speaker 302 (on the sound emitting side). The press-fitting member 305 is press-fitted between the wall portion of the storage portion 303 on the back side) and the cushion 304 is pushed and deformed toward the side surface portion 301 as shown in FIG. It is possible to prevent sound leakage due to close contact.

しかしながら、スピーカの位置と、筐体の側面部の開口の位置とを重なるようにして、スピーカの音を放出する側を筐体の側面部の開口に対向させて、スピーカを配置する上記従来技術では、筐体内に各種部品を実装して組み立てた時に、スピーカが押圧される際に、同時にクッションが押されることによって変形させるようにできないために、音洩防止用に、圧入部材を用いる必要があった。しかも、圧入部材を圧入させるために特別な治具を用いる必要があった。
このように、圧入部材等の構成部品数の増加を招くと共に、組立作業時に手間と時間がかかるという問題があった。
However, the above-described conventional technique in which the speaker is disposed so that the position of the speaker and the position of the opening on the side surface of the housing overlap with each other and the sound emission side of the speaker is opposed to the opening on the side surface of the housing. Then, when various parts are mounted and assembled in the housing, when the speaker is pressed, it cannot be deformed by pressing the cushion at the same time. Therefore, it is necessary to use a press-fitting member for preventing sound leakage. there were. In addition, it is necessary to use a special jig for press-fitting the press-fitting member.
As described above, the number of components such as press-fitting members is increased, and there is a problem that it takes time and labor during assembly work.

このため、筐体の側面部と、この側面部に対向するスピーカの放音部の端面とを実装方向に対して斜めにし、筐体内に各種部品を実装して組み立てた時に、スピーカが受ける押圧力によって、同時にクッションが押されて変形するように構成した技術が提案されている(例えば、特許文献3参照。)
特開2001−211241号公報 特開平10−84192号公報 特開平7−111524号公報
For this reason, the side surface portion of the housing and the end surface of the sound emitting portion of the speaker facing the side surface portion are inclined with respect to the mounting direction, and the components received by the speaker when assembled and assembled in the housing are assembled. A technique has been proposed in which a cushion is simultaneously pressed and deformed by pressure (see, for example, Patent Document 3).

また、第2の問題点は、スピーカが実装された基板を筐体内に組み込む場合に、構成部品の寸法のばらつき等のために、例えば、スピーカの開口位置と、筐体の開口位置とがずれてしまうことがあり、位置決めが正確になされないという点である。
The first problem to be solved is that, in the above prior art, the clamping force along the direction perpendicular to the substrate surface at the time of assembly is used to make contact with the pressing force along the direction perpendicular to the inclined surface. In this case, a sufficient pressing force for this contact cannot be obtained, and sound leakage cannot be reliably prevented.
The second problem is that, for example, when the board on which the speaker is mounted is incorporated in the housing, the opening position of the speaker is not aligned with the opening position of the housing due to variations in the dimensions of the components. In other words, the positioning is not performed accurately.

この発明は、上述の事情に鑑みてなされたもので、機器の薄型化に寄与し、かつ、構成部品数を低減させて、簡素な構成で、密着のための十分な押圧力を得て、確実に音洩れを防止することができる携帯型電子機器における小型スピーカ実装構造及び該構造を備えた携帯型電子機器を提供することを第1の目的としている。

この例の携帯電話機1を組み立てるには、まず、図10(a)に示すように、クッション部材25が先端面7b及び天井面7fの一部を覆うように貼り付けられ小型スピーカ7を、その先端部を上にして傾けた状態で、案内リブ22f,22fの案内によって、先端部をリアカバー22の開口部22aの内部側縁部に押し当て、座面部7dをフック部22cに引っ掛ける。
次に、同図(b)に示すように、座面部7dをフック部22cに引っ掛けた状態で、案内リブ22f,22fの案内によって、フック部22cの引掛部位を中心に小型スピーカ7を回転させて、小型スピーカ7の後端部をフック部22gの先端部に接触させながら引き上げる。ここで、クッション部材25は、傾斜面22b(特に圧接用リブ22d,22d)と小型スピーカ7の先端面7bとの間、及び下面22eと天井面7fとの間に挟まれ圧接されて徐々に変形していく。
To assemble the cellular phone 1 of this example, first, as shown in FIG. 10A, the cushion member 25 is attached so as to cover a part of the tip surface 7b and the ceiling surface 7f, and the small speaker 7 is attached. With the tip end tilted upward, the guide ribs 22f and 22f guide the tip portion against the inner edge of the opening 22a of the rear cover 22, and the seat surface portion 7d is hooked on the hook portion 22c.
Next, as shown in FIG. 5B, the small speaker 7 is rotated around the hooked portion of the hook portion 22c by the guide ribs 22f and 22f with the seat surface portion 7d hooked on the hook portion 22c. Then, the rear end portion of the small speaker 7 is pulled up while being in contact with the front end portion of the hook portion 22g. Here, the cushion member 25 is sandwiched between the inclined surface 22b (particularly the pressure-contacting ribs 22d and 22d) and the front end surface 7b of the small speaker 7 and between the lower surface 22e and the ceiling surface 7f, and is gradually pressed. It will be transformed.

これによって、フック部22gは小型スピーカ7から離反するように撓み、同図(c)に示すように、爪部7cがフック部22gに係止されて、小型スピーカ7は、リアカバー22の裏面側に位置決めされた状態で取り付けられる。
ここで、クッション部材25は、傾斜面22b(特に圧接用リブ22d,22d)と小型スピーカ7の先端面7bとの間、及び下面22eと天井面7fとの間に挟まれ、それぞれ、例えば、先端面7b、天井面7fに略垂直な方向に沿った圧接力を受けて圧接されて変形する。
As a result, the hook portion 22g bends away from the small speaker 7, and the claw portion 7c is locked to the hook portion 22g as shown in FIG. It is attached in a state where it is positioned.
Here, the cushion member 25 is sandwiched between the inclined surface 22b (particularly the pressure contact ribs 22d and 22d) and the front end surface 7b of the small speaker 7, and between the lower surface 22e and the ceiling surface 7f. It receives pressure contact force along a direction substantially perpendicular to the front end surface 7b and the ceiling surface 7f and is deformed by pressure contact.

これによって、リアカバー22の開口部22aの内部側縁部と、小型スピーカ7の開口部7aとは、圧接されたクッション部材25を介して密閉され、音洩れが防止された状態で、接合される。下面22eと天井面7fとの間も、圧接されたクッション部材25によって塞がれて、下面22e側への音洩れも防止される。
また、小型スピーカ7は、傾斜面22b(圧接用リブ22d,22dを含む)、フック部22c、案内リブ22f,22f、及びフック部22gによって、開口部22aと開口部7aとが正確に対向配置されるように、かつ、圧接されて変形されたクッション部材25を介して、開口部22aと開口部7aとの間が音響的に密に接合するように保持されている。
As a result, the inner side edge of the opening 22a of the rear cover 22 and the opening 7a of the small speaker 7 are sealed through the pressure-welded cushion member 25 and joined in a state in which sound leakage is prevented. . The lower surface 22e and the ceiling surface 7f are also closed by the pressed cushion member 25, and sound leakage to the lower surface 22e side is also prevented.
In addition, the small speaker 7 has the opening 22a and the opening 7a accurately opposed to each other by the inclined surface 22b (including the pressure contact ribs 22d and 22d), the hook 22c, the guide ribs 22f and 22f, and the hook 22g. As described above, the opening 22a and the opening 7a are held so as to be acoustically and closely joined via the cushion member 25 that is deformed by pressure contact.

一方、フロントケース21に、表示部9を構成する光学部品や主基板等を組み付けた後、小型スピーカ7を搭載する補助基板を組み付ける。
この後、小型スピーカ7が取り付けられたリアカバー22を、フロントケース21と合わせる。
ここで、小型スピーカ7は、傾斜面22b(圧接用リブ22d,22dを含む)、フック部22c、案内リブ22f,22f、及びフック部22gによって、接続端子7e,7eが補助基板上の所定の部位に形成された接点に電気的に接続された状態で、補助基板上に配置されるように、位置決めされた状態で保持されている。したがって、接続端子7e,7eは、補助基板の対応する接点に接触する。
さらに、一対の接続端子7e,7eは、弾性変形した状態で補助基板上の接点に電気的に接続されて確実に電気的接続が図られる。
On the other hand, after assembling an optical component, a main substrate, and the like constituting the display unit 9 to the front case 21, an auxiliary substrate on which the small speaker 7 is mounted is assembled.
Thereafter, the rear cover 22 to which the small speaker 7 is attached is aligned with the front case 21.
Here, in the small speaker 7, the connection terminals 7e and 7e are provided on the auxiliary substrate by the inclined surface 22b (including the pressure contact ribs 22d and 22d), the hook portion 22c, the guide ribs 22f and 22f, and the hook portion 22g. It is held in a positioned state so as to be disposed on the auxiliary substrate in a state where it is electrically connected to a contact formed on the part. Therefore, the connection terminals 7e and 7e are in contact with corresponding contacts of the auxiliary board.
Further, the pair of connection terminals 7e, 7e are electrically connected to the contacts on the auxiliary substrate in a state of being elastically deformed, so that the electrical connection is reliably achieved.

次に、フロントケース21と、リアカバー22とを嵌合することによって、又は雌ねじや雄ねじ等の固定具による締付けによって、小型スピーカ7は、リアカバー22と補助基板との間に圧接状態で挟まれる。すなわち、補助基板に垂直な方向に沿って締付力が与えられる。
これによって、クッション部材25がさらに両側から圧接されて変形し、接合部位での密着性がさらに高められる。
Next, the small speaker 7 is sandwiched between the rear cover 22 and the auxiliary substrate by fitting the front case 21 and the rear cover 22 or by fastening with a fixing tool such as a female screw or a male screw. That is, a tightening force is applied along a direction perpendicular to the auxiliary substrate.
Thereby, the cushion member 25 is further pressed and deformed from both sides, and the adhesion at the joint portion is further enhanced.

こうして組み立てられた携帯電話機1において、筐体を開いた状態で、例えば着信があると、制御部13は、小型スピーカ7に所定の信号を与えるように制御し、これによって、小型スピーカ7は、所定の着信音を発生する。
この着信音は、小型スピーカ7の開口部7aから放射され、開口部7aと開口部22aとのクッション部材25を介した密閉性が保たれた接合部位を音洩れすることなく通過し、開口部22aがら外部に放射される。
また、例えば、サイトからダウンロードしたプログラムを実行する場合に、筐体を開いた状態で、画像が主表示部7に表示されると共に、小型スピーカ7から出力された音声は開口部22aから放射される。
開口部7aと開口部22aとのクッション部材25を介した接合部位での密閉性が保たれ、音洩れが防止され、途中で音波が放散しないので、開口部22aからは、ユーザは、適切な音量で明瞭な着信音等を聞くことができる。
In the cellular phone 1 assembled in this way, for example, when there is an incoming call with the housing opened, the control unit 13 controls the small speaker 7 to give a predetermined signal, whereby the small speaker 7 A predetermined ring tone is generated.
This ringing tone is radiated from the opening 7a of the small speaker 7 and passes through the joint portion of the opening 7a and the opening 22a through the cushion member 25 without being leaked. 22a is emitted to the outside.
In addition, for example, when executing a program downloaded from a site, an image is displayed on the main display unit 7 with the housing opened, and sound output from the small speaker 7 is radiated from the opening 22a. The
Since the airtightness at the joint portion between the opening 7a and the opening 22a through the cushion member 25 is maintained, sound leakage is prevented, and sound waves are not radiated on the way. Listen to clear ringtones, etc. at volume.

このように、この例の構成によれば、リアカバー22の裏面側に、傾斜面22b(圧接用リブ22d,22dを含む)、フック部22c、案内リブ22f,22f、及びフック部22gが一体的に形成され、かつ、所定の角度で傾斜した先端面7bと傾斜面22bとが互いに平行な状態で対向配置されているので、筐体の側面側からに音声を放射させる場合であっても、簡素な構成で、十分な押圧力でクッション部材25を圧接して変形させて、開口部22aと開口部7aとの接合部位で、確実に音洩れを防止することができる。
したがって、開口部22aと開口部7aとの接合部位での密閉性が保たれるため、途中で音波が放散せず、音洩れを防止することができ、ユーザは音声を適切な音量で明瞭に聞き取ることができる。
Thus, according to the configuration of this example, the inclined surface 22b (including the pressure contact ribs 22d and 22d), the hook portion 22c, the guide ribs 22f and 22f, and the hook portion 22g are integrally formed on the rear surface side of the rear cover 22. And the tip surface 7b and the inclined surface 22b that are inclined at a predetermined angle are arranged opposite to each other in parallel with each other, so that even when sound is emitted from the side surface side of the housing, With a simple configuration, the cushion member 25 can be pressed and deformed with a sufficient pressing force, and sound leakage can be reliably prevented at the joint portion between the opening 22a and the opening 7a.
Therefore, since the sealing property at the joint portion between the opening 22a and the opening 7a is maintained, sound waves are not diffused on the way, and sound leakage can be prevented, and the user can clearly hear the sound at an appropriate volume. I can hear you.
