  • the present invention relates to a speaker device.
  • Patent Document 1 a yoke, a magnet, a plate, and a frame constituting a magnetic circuit are stacked, and then an epoxy or acrylic resin is formed in a gap formed between the yoke, the magnet, the plate, the lower end of the frame, and a plunge.
  • a speaker unit is described in which each member is fixed to each other by injecting a system adhesive and fixing the yoke, magnet and plate and the peripheral surface of the frame to the inner surface of the flange at the lower end of the frame. .
  • Conventional speaker devices are generally manufactured by joining a plurality of constituent members with an adhesive. For this reason, the hardening time of an adhesive agent may be needed for every joining process of each part. Further, when the constituent members are joined to each other with an adhesive, the adhesive has viscosity until the adhesive is completely cured, and thus the positional relationship between the constituent members joined to each other may be shifted. In order to avoid this, it is necessary to accurately fix the positions of the components to be joined to each other until the adhesive is completely cured, which may lead to complicated processes.

Description

スピーカ装置Speaker device
　本発明は、スピーカ装置に関するものである。 The present invention relates to a speaker device.
　下記特許文献１には、磁気回路を構成するヨーク、マグネット及びプレートとフレームとを積み上げた後、ヨーク、マグネット及びプレートとフレームの下端部及びプランジとの間に形成される隙間にエポキシ系又はアクリル系の接着剤を注入し、ヨーク、マグネット及びプレートとフレームの周側面をフレームの下端部のフランジの内面に固着させることで、各部材を相互に固着するようにしたスピーカユニットが記載されている。 In Patent Document 1 below, a yoke, a magnet, a plate, and a frame constituting a magnetic circuit are stacked, and then an epoxy or acrylic resin is formed in a gap formed between the yoke, the magnet, the plate, the lower end of the frame, and a plunge. A speaker unit is described in which each member is fixed to each other by injecting a system adhesive and fixing the yoke, magnet and plate and the peripheral surface of the frame to the inner surface of the flange at the lower end of the frame. .
特開平８－１４０１８９号公報Japanese Patent Laid-Open No. 8-140189
　従来のスピーカ装置は、一般に複数の構成部材を接着剤で接合して製造される。このため、接着剤の硬化時間が各部の接合工程毎に必要になる場合がある。また、構成部材同士を接着剤で接合すると、接着剤が完全に硬化するまでは、接着剤は粘性を有するので、互いに接合される構成部材同士の位置関係がずれる場合がある。これを回避するには、接着剤が完全に硬化するまで互いに接合される構成部材同士の位置を精度よく固定しておくことが必要になり、これが工程の煩雑さを招く場合がある。 Conventional speaker devices are generally manufactured by joining a plurality of constituent members with an adhesive. For this reason, the hardening time of an adhesive agent may be needed for every joining process of each part. Further, when the constituent members are joined to each other with an adhesive, the adhesive has viscosity until the adhesive is completely cured, and thus the positional relationship between the constituent members joined to each other may be shifted. In order to avoid this, it is necessary to accurately fix the positions of the components to be joined to each other until the adhesive is completely cured, which may lead to complicated processes.
　一方、薄型のスピーカ装置は、電子機器内、車室内、家屋内等でスピーカ装置の設置スペースを薄くできるので、スピーカ装置を備えた電子機器の薄型化や、スピーカ装置を設置する室内の居住空間確保において有効である。特に、近年普及しているフラットパネルディスプレイ内にスピーカ装置を設置する場合や、居住空間の限られる車室内の壁面等にスピーカ装置を取り付ける場合等は、より薄型のスピーカ装置が求められる。 On the other hand, since the thin speaker device can reduce the installation space of the speaker device in the electronic device, in the vehicle interior, in the house, etc., the electronic device equipped with the speaker device can be thinned and the living space in the room where the speaker device is installed. It is effective in securing. In particular, a thinner speaker device is required when the speaker device is installed in a flat panel display that has been spread in recent years, or when the speaker device is attached to a wall surface of a vehicle interior where the living space is limited.
　しかしながら、一般のスピーカ装置は、振動するボイスコイルと振動板がスピーカ装置の厚さ方向に連ねて配置されている。このため、比較的大きな振幅でボイスコイルや振動板を振動させて大音量で再生音を提供すること（大音量化）とスピーカ装置の薄型化とを両立することが難しいという場合がある。これに対しては、ボイスコイルの振動方向を振動板の振動方向とは異なる方向にして、振動伝達効率の高い振動方向変換部を介してボイスコイルと振動板を繋ぐことで、スピーカ装置の高音量化と薄型化を両立させることが可能になる。 However, in a general speaker device, a vibrating voice coil and a diaphragm are arranged continuously in the thickness direction of the speaker device. For this reason, there are cases where it is difficult to achieve both reproduction of sound with a large volume by vibrating a voice coil or a diaphragm with a relatively large amplitude (high volume) and thinning of the speaker device. In response to this, the vibration direction of the voice coil is set to a direction different from the vibration direction of the diaphragm, and the voice coil and the diaphragm are connected via a vibration direction converter having high vibration transmission efficiency. It is possible to achieve both weight reduction and thinning.
　このような振動方向変換部を備えたスピーカ装置では、ボイスコイルの振動方向と振動板の振動方向が異なるので、ボイスコイルの振動方向に沿った振動と振動板の振動方向に沿った振動の２種類の振動がスピーカ装置内に混在することになる。そのため、スピーカ装置を構成する複数の構成部材を接着剤で接合した際に、これら複数の構成部材の接合箇所における固定力は、ボイスコイルの振動方向に対し、比較的小さい場合がある。例えば、接合箇所における固定力は、振動板の振動方向に対して比較的大きくても、ボイスコイルの振動方向に対して比較的小さい場合がある。そのため、接合箇所には、ボイスコイルの振動に伴う振動などの外力（剪断力）に対して比較的大きい固定力が求められる。仮に接合箇所に剥がれ等が生じた場合には、複数の構成部材がボイスコイルの振動方向に沿って位置ずれを起こしてしまう。また、複数の構成部材が衝突して異音を発生する場合がある。 In the speaker device including such a vibration direction conversion unit, the vibration direction of the voice coil and the vibration direction of the diaphragm are different, so that vibration along the vibration direction of the voice coil and vibration along the vibration direction of the diaphragm are two. Various types of vibrations are mixed in the speaker device. For this reason, when a plurality of constituent members constituting the speaker device are joined with an adhesive, the fixing force at the joining portion of the plurality of constituent members may be relatively small with respect to the vibration direction of the voice coil. For example, the fixing force at the joint location may be relatively small with respect to the vibration direction of the voice coil even though it is relatively large with respect to the vibration direction of the diaphragm. For this reason, a relatively large fixing force is required for the joint portion with respect to an external force (shearing force) such as vibration accompanying vibration of the voice coil. If peeling or the like occurs at the joint location, a plurality of constituent members will be displaced along the vibration direction of the voice coil. In addition, a plurality of structural members may collide and generate abnormal noise.
　本発明は、このような問題に対処することを課題の一例とするものである。接着剤の硬化時間によるスピーカ装置の生産性低下を解消すること、スピーカ装置の製造工程において、接着剤が完全に硬化するまで複数の構成部材の位置を固定することによる煩雑性を解消すること、ボイスコイルの振動に伴う振動などの外力（剪断力）に対して、接合箇所が比較的大きい固定力を有すること、等が本発明の目的である。 The present invention is an example of a problem to deal with such a problem. Eliminating the productivity reduction of the speaker device due to the curing time of the adhesive, eliminating the troublesomeness of fixing the positions of a plurality of components until the adhesive is completely cured in the manufacturing process of the speaker device, It is an object of the present invention that the joint location has a relatively large fixing force against an external force (shearing force) such as vibration accompanying the vibration of the voice coil.
　このような目的を達成するために、本発明によるスピーカ装置は、以下の構成を少なくとも具備するものである。 In order to achieve such an object, the speaker device according to the present invention has at least the following configuration.
　振動板と前記振動板を振動自在に支持する静止部と前記振動板に振動を与える駆動部とを備え、前記駆動部は、音声信号によって前記振動板の振動とは異なる方向に振動する駆動部材と、前記駆動部材の振動を当該駆動部材の振動方向に対して交差する方向に方向変換して前記振動板を振動させる振動方向変換部とを備え、前記振動板と前記静止部と前記駆動部のそれぞれは一つ又は複数のスピーカ用構成部材によって構成され、互いに固定される複数のスピーカ用構成部材のうち、一方の前記スピーカ用構成部材は突起状部を備え、他方の前記スピーカ用構成部材は前記突起状部が挿入される孔部を備え、前記突起状部は、前記駆動部材の振動方向に対して交差する方向に沿って突出していることを特徴とするスピーカ装置。 A driving member that vibrates in a direction different from the vibration of the diaphragm by an audio signal, comprising: a diaphragm; a stationary part that supports the diaphragm so as to freely vibrate; and a driving part that applies vibration to the diaphragm.

In the description of each drawing, common portions are denoted by the same reference numerals, and a part of overlapping description is omitted. FIG. 1 is an explanatory diagram (sectional view) showing the overall configuration of a speaker device according to an embodiment of the present invention. The speaker device 1 includes a stationary part 10, a driving part 20, and a diaphragm 30. The stationary part 10 is a part that is relatively stationary with respect to the vibration of the driving part 20 and the diaphragm 30 and that is a part that supports the diaphragm 30 in a freely oscillating manner. The stationary portion is not intended to be completely stationary. For example, the stationary portion only needs to be stationary to the extent that the diaphragm 30 can be supported, and vibration generated when the speaker device 1 is driven propagates. The vibration may propagate to the entire stationary part. Here, the stationary portion 10 corresponds to a frame, a part of a magnetic circuit, a mounting location where the speaker device 1 is mounted, and the like which will be described later. The drive unit 20 is a part of the speaker device 1 that generates a driving force that vibrates the diaphragm 30. The diaphragm 30 is a part of the speaker device 1 that oscillates by the driving force of the driving unit 20 to emit sound.

　駆動部材２０Ａは、ボイスコイル２１によって構成することができる。ボイスコイル２１は振動方向（図示Ｘ軸方向）に沿って剛性を有する。ボイスコイル２１自体が剛性を有するか、或いは図示Ｘ軸方向に剛性を有するボイスコイル支持部２２にボイスコイル２１を固着して駆動部材２０Ａを構成することもできる。駆動部材２０Ａは、ボイスコイル２１に限定されず、圧電素子や磁歪型素子、形状記憶金属（人工筋肉）であっても構わない。2009年7年29日に国際出願したPCT/JP2009/063527に記載される記載される全ての内容は、本出願に組み込まれる。 The driving member 20A can be constituted by a voice coil 21. The voice coil 21 has rigidity along the vibration direction (X-axis direction in the drawing). The voice coil 21 itself has rigidity, or the driving member 20A can be configured by fixing the voice coil 21 to the voice coil support portion 22 having rigidity in the X-axis direction in the drawing. The drive member 20A is not limited to the voice coil 21, and may be a piezoelectric element, a magnetostrictive element, or a shape memory metal (artificial muscle). All the contents described in PCT / JP2009 / 063527 filed internationally on July 29, 2009 are incorporated in this application.

　スピーカ装置１は、ボイスコイル２１に音声信号が入力されると、ボイスコイル２１を流れる電流が磁気ギャップ２３Ｇの磁束を横切ることでローレンツ力が生じ、これが振動板３０を振動させる駆動力になる。振動方向変換部４０は、対面する第１の振動板３０－１と第２の振動板３０－２との間に設けられている。また、振動方向変換部４０は、第１の振動板３０－１と第２の振動板３０－２を連結して互いに近接又は離間するように連動させる。また、振動方向変換部４０は、ボイスコイル２１の振動方向（図示Ｘ軸方向）とは異なる方向（図示Ｚ軸方向）に第１の振動板３１－１と第２の振動板３１－２を振動させる。 In the speaker device 1, when an audio signal is input to the voice coil 21, a current flowing through the voice coil 21 crosses the magnetic flux of the magnetic gap 23 </ b> G to generate a Lorentz force, which becomes a driving force that vibrates the diaphragm 30. The vibration direction converter 40 is provided between the first diaphragm 30-1 and the second diaphragm 30-2 facing each other.

Vibrate.
　振動方向変換部４０におけるボイスコイル用連結部分４３は、関節部４２を介して第１のリンク部分４１－１の一方の端部に連結している。振動板用連結部分４４は、関節部４２を介して第１のリンク部分４１－１の他方の端部に連結している。第２のリンク部分４１－２の一方の端部は、関節部４２を介して第１のリンク部分４１－１の中間部分に連結している。第２のリンク部分４１－２の他方の端部は、関節部４２を介してフレーム用連結部分４５に連結している。 The voice coil connecting portion 43 in the vibration direction changing portion 40 is connected to one end portion of the first link portion 41-1 via the joint portion 42.

The joint portion 42 provided therebetween is referred to as a second joint portion 42-2. The positions of the first joint part 42-1 and the second joint part 42-2 are substantially the same in the vibration direction (Z-axis direction) of the diaphragm 30.
　振動方向変換部４０のリンク部分４１は、図示の例では、実質的に上下対称に構成され、一対のボイスコイル用連結部分４３，４３間にボイスコイル２１又はボイスコイル支持部２２が挟持されて連結されている。振動方向変換部４０は、実質的に平行に配置されるリンク部分４１Ａ、４１Ｂを備える。これらリンク部分４１Ａとリンク部分４１Ｂは、平行リンクを構成している。これによると、ボイスコイル２１の振動によって一対のボイスコイル用連結部分４３，４３がＸ軸方向に沿って振動すると、リンク部分４１Ａとリンク部分４１Ｂは実質的に平行状態を維持しながら角度変更する。リンク部分４１Ａ、４１Ｂが角度変更することで、一対のボイスコイル用連結部分４３，４３の振動が、一対の振動板用連結部分４４，４４の振動に変換される。この時、一対のボイスコイル用連結部分４３、４３は、Ｘ軸方向に沿って、互いに逆向きに振動する。また、一対の振動板用連結部分４４、４４は、Ｚ軸方向に沿って、互いに逆向きに振動する。 In the illustrated example, the link portion 41 of the vibration direction conversion unit 40 is substantially vertically symmetrical, and the voice coil 21 or the voice coil support unit 22 is sandwiched between the pair of voice coil connection portions 43 and 43. It is connected. The vibration direction converter 40 includes link portions 41A and 41B that are arranged substantially in parallel. The link part 41A and the link part 41B constitute a parallel link. According to this, when the pair of voice coil connecting portions 43 and 43 vibrate along the X-axis direction due to the vibration of the voice coil 21, the link portion 41A and the link portion 41B change their angles while maintaining a substantially parallel state. . By changing the angles of the link portions 41A and 41B, the vibration of the pair of voice coil connecting portions 43 and 43 is converted into the vibration of the pair of diaphragm connecting portions 44 and 44. At this time, the pair of voice coil connecting portions 43 and 43 vibrate in opposite directions along the X-axis direction. Further, the pair of diaphragm connecting portions 44 and 44 vibrate in the opposite directions along the Z-axis direction.
　スピーカ装置１はボイスコイル２１に角度変更自在に連結される振動方向変換部４０を一対備えている。ボイスコイル２１を境界として、一対の振動板３０（第１の振動板３０－１，第２の振動板３０－２）が、Ｚ軸方向において、ボイスコイル２１の両側に配置されている。一対の振動方向変換部４０は、ボイスコイル２１の振動を一対の振動板３０（第１の振動板３０－１，第２の振動板３０－２）に伝達する。 The speaker device 1 includes a pair of vibration direction converters 40 that are connected to the voice coil 21 so that the angle can be changed. A pair of diaphragms 30 (first diaphragm 30-1 and second diaphragm 30-2) are arranged on both sides of the voice coil 21 in the Z-axis direction with the voice coil 21 as a boundary. The pair of vibration direction converters 40 transmits the vibration of the voice coil 21 to the pair of diaphragms 30 (the first diaphragm 30-1 and the second diaphragm 30-2).
　図２はスピーカ装置１の各構成部材の連結構造を示した説明図である。静止部１０と駆動部２０と振動板３０のそれぞれは一つ又は複数のスピーカ用構成部材１Ａによって構成されている。スピーカ用構成部材１Ａは、静止部１０，駆動部２０，振動板３０の一部又は全体を構成する部材である。静止部１０としては、フレーム１１，振動板用フレーム１３等になる。駆動部２０としては、ボイスコイル２１，ボイスコイル支持部２２，磁気回路２３の構成要素（磁気回路２３は静止部１０にもなりうる）等になる。振動板３０としては、第１の振動板３０－１，第２の振動板３０－２，第１のエッジ３１－１，第２のエッジ３１－２等がスピーカ用構成部材１Ａになる。スピーカ用構成部材１Ａを２種類に分けるとすると、ボイスコイル２１，ボイスコイル支持部２２，振動板３０（第１の振動板３０－１，第２の振動板３０－２），エッジ３１（第１のエッジ３１－１，第２のエッジ３１－２），振動方向変換部４０の各部位等が振動系部材１Ａ－１であり、フレーム１１，振動板用フレーム１３，磁気回路２３等が静止系部材１Ａ－２である。複数のスピーカ用構成部材１Ａは、駆動部材２０Ａの振動方向に対して交差する方向にて、所定の間隔を隔てて重ねて配置されても構わない。 FIG. 2 is an explanatory view showing a connection structure of each component of the speaker device 1. Each of the stationary unit 10, the driving unit 20, and the diaphragm 30 is configured by one or a plurality of speaker components 1A. The speaker component 1 </ b> A is a member that constitutes part or all of the stationary part 10, the drive part 20, and the diaphragm 30. The stationary part 10 includes a frame 11, a diaphragm frame 13, and the like. The drive unit 20 is a component of a voice coil 21, a voice coil support unit 22, a magnetic circuit 23 (the magnetic circuit 23 can also be a stationary unit 10), and the like. As the diaphragm 30, the first diaphragm 30-1, the second diaphragm 30-2, the first edge 31-1, the second edge 31-2, and the like constitute the speaker component 1A. If the speaker component 1A is divided into two types, the voice coil 21, the voice coil support portion 22, the diaphragm 30 (the first diaphragm 30-1 and the second diaphragm 30-2), and the edge 31 (the first) The first edge 31-1, the second edge 31-2), each part of the vibration direction changing portion 40, etc. are vibration system members 1A-1, and the frame 11, the diaphragm frame 13, the magnetic circuit 23, etc. are stationary. This is the system member 1A-2. The plurality of speaker constituent members 1A may be arranged so as to overlap each other at a predetermined interval in a direction intersecting the vibration direction of the drive member 20A.
　図２（ａ）～（ｃ）に示すように、スピーカ装置１は、前述したスピーカ用構成部材１Ａ（１Ａ１，１Ａ２）が互いに固定又は接合されて構成されおり、互いに固定される一方のスピーカ用構成部材１Ａ１は突起状部１Ｂを備えており、互いに固定される他方のスピーカ用構成部材１Ａ２は突起状部１Ｂが挿入される孔部１Ｃを備えている。そして、突起状部１Ｂは、駆動部材２０Ａ（ボイスコイル２１又はボイスコイル支持部２２）の振動方向（図示Ｘ軸方向）に対して交差する方向に沿って突出している。 As shown in FIGS. 2A to 2C, the speaker device 1 is configured by fixing or joining the above-described speaker components 1A (1A1, 1A2) to each other, and for one speaker fixed to each other. The constituent member 1A1 includes a protruding portion 1B, and the other speaker constituent member 1A2 fixed to each other includes a hole portion 1C into which the protruding portion 1B is inserted. The protruding portion 1B protrudes along a direction that intersects the vibration direction (X-axis direction in the drawing) of the drive member 20A (voice coil 21 or voice coil support portion 22).
　これによると、突起状部１Ｂが駆動部材２０Ａの振動方向に対して交差する方向に沿って突出しているため、突起状部１Ｂは、駆動部材２０Ａの振動を受け止めて、駆動部材２０Ａの振動がスピーカ用構成部材１Ａ１，１Ａ２の固定状態に悪影響を及ぼすことを抑制することができる。また、孔部１Ｃの内径と突起状部１Ｂの外径との隙間を実質的に無くしても構わない。この隙間を実質的に無くすことで、スピーカ用構成部材１Ａ１，１Ａ２の位置関係が、比較的高い精度で定まる。また、突起状部１Ｂは、駆動部材２０Ａの振動により、スピーカ用構成部材１Ａ１，１Ａ２の位置関係がずれることを抑止できる。また、突起状部１Ｂは、駆動部材２０Ａの振動方向に対し、剛性（曲げ剛性）を備えていても構わない。突起状部１Ｂが剛性を備えることで、スピーカ用構成部材１Ａ１，１Ａ２の位置関係がずれることを抑止することができる。 According to this, since the protruding portion 1B protrudes along the direction intersecting the vibration direction of the driving member 20A, the protruding portion 1B receives the vibration of the driving member 20A and the vibration of the driving member 20A is detected. It is possible to suppress adverse effects on the fixed state of the speaker structural members 1A1 and 1A2. Further, the gap between the inner diameter of the hole 1C and the outer diameter of the protruding portion 1B may be substantially eliminated. By substantially eliminating this gap, the positional relationship between the speaker components 1A1 and 1A2 is determined with relatively high accuracy. Further, the protruding portion 1B can prevent the positional relationship between the speaker structural members 1A1 and 1A2 from being shifted due to the vibration of the driving member 20A. Further, the protruding portion 1B may have rigidity (bending rigidity) with respect to the vibration direction of the drive member 20A. Since the protruding portion 1B has rigidity, it is possible to prevent the positional relationship between the speaker structural members 1A1 and 1A2 from deviating.
　突起状部１Ｂおよび孔部１Ｃが配置される箇所は、複数の振動系部材１Ａ－１が連結する連結部１Ｆ、複数の静止系部材１Ａ－２が連結する連結部１Ｆ、または振動系部材１Ａ－１と静止系部材１Ａ－２とが連結する連結部１Ｆである。 The projecting portion 1B and the hole 1C are arranged at a connecting portion 1F to which a plurality of vibration system members 1A-1 are connected, a connecting portion 1F to which a plurality of stationary system members 1A-2 are connected, or a vibration system member 1A. -1 and the stationary member 1A-2 are connecting portions 1F.
　一方のスピーカ用構成部材１Ａ１は、突起状部１Ｂが設けられる固定面１Ｄ（１Ｄ１）を備えている。他方のスピーカ用構成部材１Ａ２は、孔部１Ｃが設けられる固定面１Ｄ（１Ｄ２）を備えている。一方のスピーカ用構成部材１Ａ１および他方のスピーカ用構成部材１Ａ２の各固定面１Ｄ１，１Ｄ２は、駆動部材２０Ａの振動方向（図示Ｘ軸方向）に沿って延在している。これら固定面１Ｄ１、１Ｄ２を備えるとともに、駆動部材２０Ａの振動方向と振動板３０の振動方向が異なるスピーカ装置１では、スピーカ用構成部材１Ａ１が有する突起状部１Ｂをスピーカ用構成部材１Ａ２が有する孔部１Ｃに挿入することで、駆動部材２０Ａの振動方向に対しての固定状態を安定化できる。また、固定面１Ｄ１と固定面１Ｄ２とを当接させることで、振動板３０の振動方向に対する固定状態を安定化できる。 One speaker component 1A1 includes a fixed surface 1D (1D1) on which the protruding portion 1B is provided. The other speaker component 1A2 includes a fixed surface 1D (1D2) provided with a hole 1C. The fixed surfaces 1D1 and 1D2 of one speaker component 1A1 and the other speaker component 1A2 extend along the vibration direction (X-axis direction in the drawing) of the drive member 20A. In the speaker device 1 having the fixed surfaces 1D1 and 1D2 and having different vibration directions of the drive member 20A and the vibration plate 30, the speaker component 1A2 has a protruding portion 1B of the speaker component 1A1. By inserting in the part 1C, the fixed state with respect to the vibration direction of the drive member 20A can be stabilized. Moreover, the fixed state with respect to the vibration direction of the diaphragm 30 can be stabilized by contacting the fixed surface 1D1 and the fixed surface 1D2.
　また、図２（ｂ）に示すように、一方のスピーカ用構成部材１Ａ１は突起状部１Ｂを複数備え、他方のスピーカ用構成部材１Ａ２は孔部１Ｃを複数備えている場合で、複数の突起状部１Ｂの少なくとも一つは、振動板３０の振動方向（図示Ｚ軸方向）に対し交差する方向であって駆動部材２０Ａの振動方向（図示Ｘ軸方向）に沿って突出している。これによると、突起状部１Ｂが振動板３０の振動方向に対して交差する方向に沿って突出しているので、振動板３０の振動を突起状部１Ｂが受け止めて、振動板３０の振動がスピーカ用構成部材１Ａ１，１Ａ２の固定状態に悪影響を及ぼすことを抑制することできる。駆動部材２０Ａの振動方向と振動板３０の振動方向が異なるスピーカ装置１では、駆動部材２０Ａの振動方向と振動板３０の振動方向の両方で、互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２の固定状態を安定化することができる。 Further, as shown in FIG. 2B, one speaker component 1A1 includes a plurality of protrusions 1B, and the other speaker component 1A2 includes a plurality of holes 1C. At least one of the shape portions 1B protrudes along the vibration direction (X-axis direction in the drawing) of the drive member 20A in a direction intersecting with the vibration direction (Z-axis direction in the drawing) of the diaphragm 30. According to this, since the protruding portion 1B protrudes along the direction intersecting the vibration direction of the diaphragm 30, the protruding portion 1B receives the vibration of the diaphragm 30, and the vibration of the diaphragm 30 is detected by the speaker. An adverse effect on the fixed state of the structural members 1A1 and 1A2 can be suppressed. In the speaker device 1 in which the vibration direction of the drive member 20A and the vibration direction of the diaphragm 30 are different, the speaker component members 1A1 and 1A2 fixed to each other in both the vibration direction of the drive member 20A and the vibration direction of the diaphragm 30 are fixed. The state can be stabilized.
　また、同図（ｃ）に示すように、他方のスピーカ用構成部材１Ａ２は、一方のスピーカ用構成部材１Ａ１に隣接して配置される壁部１Ｅを備える。駆動部材２０Ａの振動方向（図示Ｘ軸方向）に沿って、突起状部１Ｂと壁部１Ｅは並べて配置されている。壁部１Ｅは、一方のスピーカ用構成部材１Ａ１の位置を規制するために設けられる。特に、駆動部材２０Ａの振動方向に沿って突起状部１Ｂに接して壁部１Ｅが配置される場合には、壁部１Eは、他方のスピーカ用構成部材１Ａ２に対する一方のスピーカ用構成部材１Ａ１の位置を規制できる。また、一方のスピーカ用構成部材１Ａ１が、突起状部１Ｂと壁部１Ｅを備えても構わない。この場合、壁部１Ｅは、一方のスピーカ用構成部材１Ａ１に対する他方のスピーカ用構成部材１Ａ２の位置を規制することができる。 Further, as shown in FIG. 5C, the other speaker component 1A2 includes a wall portion 1E disposed adjacent to the one speaker component 1A1. The projecting portion 1B and the wall portion 1E are arranged side by side along the vibration direction (X-axis direction in the drawing) of the drive member 20A. The wall 1E is provided to restrict the position of the one speaker component 1A1. In particular, when the wall portion 1E is disposed in contact with the protruding portion 1B along the vibration direction of the drive member 20A, the wall portion 1E is configured so that the speaker component member 1A1 has one speaker member relative to the other speaker component member 1A2. The position can be regulated. Further, one speaker component 1A1 may include a protruding portion 1B and a wall 1E. In this case, the wall 1E can regulate the position of the other speaker component 1A2 with respect to the one speaker component 1A1.
　突起状部１Ｂおよび孔部１Ｃは、振動系部材１Ａ－１（ボイスコイル２１，ボイスコイル支持部２２，振動板３０，エッジ３１，振動方向変換部４０等）のうち実質的に振動する部分の近傍に配置しても構わない。これによると、スピーカ用構成部材のうち、実質的に振動している一部分による外力（振動）を、直接的に突起状部１Ｂが受け止める。このため、外力（振動）が互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２の固定状態に悪影響を及ぼすことを効果的に抑止できる。実質的に振動する部分とは、振動系部材１Ａ－１の一部、振動系部材１Ａ－１を支持する静止系部材１Ａ－２の一部、振動系部材１Ａ－１の振動が直接的に伝播される静止系部材１Ａ－２の一部などが挙げられる。 The protruding portion 1B and the hole 1C are portions of the vibration system member 1A-1 (the voice coil 21, the voice coil support portion 22, the diaphragm 30, the edge 31, the vibration direction changing portion 40, etc.) that vibrate substantially. You may arrange | position in the vicinity. According to this, the protruding portion 1B directly receives an external force (vibration) caused by a portion of the speaker component that is substantially vibrating. For this reason, it can suppress effectively that an external force (vibration) exerts a bad influence on the fixed state of structural member 1A1, 1A2 for speakers which are mutually fixed. The part that vibrates substantially includes a part of the vibration system member 1A-1, a part of the stationary system member 1A-2 that supports the vibration system member 1A-1, and a vibration of the vibration system member 1A-1 directly. A part of the stationary system member 1A-2 to be propagated is exemplified.
　また、同図（ｄ）に示すように、突起状部１Ｂは、孔部１Ｃ内に配置される支柱部ａと、突起状部１Ｂを備える一方のスピーカ用構成部材１Ａが有する固定面１Ｄに対面して配置されるフランジ部ｂを備える。このフランジ部ｂは、孔部１Ｃの内側から外側に向かって延在する。フランジ部ｂの外径は、フランジ部ｂ近傍における孔部１Ｃの外径に対して大きい。これによると、支柱部ａが、支柱部ａに沿う方向に対して交差する方向における位置を規制し、フランジ部ｂが支柱部ａに沿った方向における位置を規制できる。 Further, as shown in FIG. 4D, the protruding portion 1B is formed on the fixed surface 1D of the strut portion a disposed in the hole 1C and the one speaker component 1A including the protruding portion 1B. The flange part b arrange | positioned facing is provided. The flange portion b extends from the inside to the outside of the hole 1C. The outer diameter of the flange part b is larger than the outer diameter of the hole 1C in the vicinity of the flange part b. According to this, the support | pillar part a can control the position in the direction which cross | intersects with respect to the direction along the support | pillar part a, and the flange part b can control the position in the direction along the support | pillar part a.
　一方のスピーカ用構成部材１Ａ１の固定面１Ｄ１とフランジ部ｂとの間には、他方のスピーカ用構成部材１Ａ２の固定面１Ｄ２が配置されている。また、固定面１Ｄ１，１Ｄ２は、ボイスコイル２１の振動方向に沿った面を構成している。互いに接する一方のスピーカ用構成部材１Ａ１の固定面１Ｄ１と他方のスピーカ用構成部材１Ａ２の固定面１Ｄ２は実質的に平坦であっても構わない。これによると、フランジ部ｂが固定面１Ｄ１，１Ｄ２の接触状態を保持している。このため、互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２は固定面１Ｄ１，１Ｄ２が接触した状態で、駆動部材２０Ａの振動方向と振動板３０の振動方向における固定状態を維持することができる。特に、固定面Ｄ１、Ｄ２が接触しているため、振動板３０の振動方向において、スピーカ用構成部材１Ａ１、１Ａ２がガタつくことなく、良好な固定状態を維持できる。 Between the fixed surface 1D1 of the one speaker component 1A1 and the flange portion b, the fixed surface 1D2 of the other speaker component 1A2 is disposed. The fixed surfaces 1D1 and 1D2 constitute surfaces along the vibration direction of the voice coil 21. The fixing surface 1D1 of one speaker component 1A1 that is in contact with each other and the fixing surface 1D2 of the other speaker component 1A2 may be substantially flat. According to this, the flange part b is maintaining the contact state of fixed surface 1D1, 1D2. Therefore, the speaker components 1A1 and 1A2 fixed to each other can maintain the fixed state in the vibration direction of the drive member 20A and the vibration direction of the diaphragm 30 in a state where the fixing surfaces 1D1 and 1D2 are in contact with each other. In particular, since the fixed surfaces D1 and D2 are in contact with each other, the speaker component members 1A1 and 1A2 can be maintained in a good fixed state in the vibration direction of the diaphragm 30 without rattling.
　固定面１Ｄ１，１Ｄ２はボイスコイル２１の振動方向に沿う面を備える。このため、ボイスコイル２１の振動方向において、固定面１Ｄ１を有する一方のスピーカ用構成部材１Ａ１と、固定面１Ｄ２を有する他方のスピーカ用構成部材１Ａ２とを実質的に平行に配置することができる。必要に応じて、固定面１Ｄ１，１Ｄ２の間に、樹脂部材、弾性部材、緩衝部材、接着剤などを配置することができる。 The fixed surfaces 1D1 and 1D2 have surfaces along the vibration direction of the voice coil 21. For this reason, in the vibration direction of the voice coil 21, one speaker component 1A1 having the fixed surface 1D1 and the other speaker component 1A2 having the fixed surface 1D2 can be arranged substantially in parallel. If necessary, a resin member, an elastic member, a buffer member, an adhesive, or the like can be disposed between the fixing surfaces 1D1 and 1D2.
　図２に示される例では、孔部１Ｃが支柱部ａに沿った筒形状を備えている。これに限定されず、孔部１Ｃは図２（ｅ）に示されるような、傾斜部１Ｃ－１を備えても構わない。傾斜部１Ｃ－１を孔部１Ｃに設けることで、フランジ部ｂと孔部１Ｃとの接合面を比較的大きくでき、固定力を向上させることができる。また、孔部１Ｃへの突起状部１Ｂの挿入を容易にすることができる。 In the example shown in FIG. 2, the hole 1 </ b> C has a cylindrical shape along the support column a. However, the present invention is not limited to this, and the hole 1C may include an inclined portion 1C-1 as shown in FIG. By providing the inclined portion 1C-1 in the hole portion 1C, the joint surface between the flange portion b and the hole portion 1C can be made relatively large, and the fixing force can be improved. Moreover, insertion of the protruding portion 1B into the hole 1C can be facilitated.
　図示の例では、スピーカ装置１を薄型化すべく、スピーカ用構成部材１Ａの各々は、比較的薄く構成されている。即ち、振動板３０の振動方向におけるスピーカ用構成部材１Ａの厚さは、ボイスコイル２１の振動方向における長さより小さい。振動板３０の振動方向におけるスピーカ用構成部材１Ａの厚さは、振動板３０の振動方向及びボイスコイル２１の振動方向に対して交差する方向における長さより小さい。このため、比較的薄いスピーカ用構成部材１Ａは、例えば、断面形状が湾曲状に変化するなど、変形を生じる場合がある。また、製造時の条件などにより、比較的薄いスピーカ用構成部材が、わずかながらに湾曲している場合がある。また、図示されるスピーカ装置１では、各スピーカ用構成部材１Ａを、振動板３０の振動方向に沿って積み重ねて構成される。このため、湾曲したスピーカ用構成部材１Ａを用いた場合、他のスピーカ用構成部材と良好に連結することが困難になる場合がある。湾曲したスピーカ用構成部材と他のスピーカ用構成部材とを連結した際、固定力が低減してしまう場合がある。振動板３０の振動方向において、他のスピーカ用構成部材を所望の位置に配置できない場合がある。 In the illustrated example, each speaker component 1A is configured to be relatively thin in order to make the speaker device 1 thinner. That is, the thickness of the speaker component 1 </ b> A in the vibration direction of the diaphragm 30 is smaller than the length of the voice coil 21 in the vibration direction. The thickness of the speaker component 1 </ b> A in the vibration direction of the diaphragm 30 is smaller than the length in the direction intersecting the vibration direction of the diaphragm 30 and the vibration direction of the voice coil 21. For this reason, the relatively thin speaker component 1A may be deformed, for example, the cross-sectional shape changes to a curved shape. In addition, a relatively thin speaker component may be slightly curved depending on manufacturing conditions. In the illustrated speaker device 1, each speaker component 1 </ b> A is configured to be stacked along the vibration direction of the diaphragm 30. For this reason, when the curved speaker component 1A is used, it may be difficult to satisfactorily connect to another speaker component. When a curved speaker component and another speaker component are connected, the fixing force may be reduced. In the vibration direction of the diaphragm 30, there may be a case where another speaker component cannot be disposed at a desired position.
　そこで、突起状部１Ｂと孔部１Ｃを用い、スピーカ用構成部材１Ａを他のスピーカ用構成部材に略平行な形状に維持しつつ、他のスピーカ用構成部材に固定させることができる。突起状部１Ｂと孔部１Ｃを用い、互いに連結し合うスピーカ用構成部材の固定力を向上させることができる。突起状部１Ｂと孔部１Ｃを用い、振動板３０の振動方向におけるスピーカ用構成部材の相対的な位置関係を所望の位置関係にすることができる。特に、突起状部１Ｂ又は孔部１Ｃの周囲に固定面１Ｄを設けることで、互いに連結し合うスピーカ用構成部材１Ａの連結部分を互いに略平行な形状に維持しつつ固定することができる。 Therefore, using the protruding portion 1B and the hole 1C, the speaker component 1A can be fixed to another speaker component while maintaining the shape substantially parallel to the other speaker components. By using the protruding portion 1B and the hole portion 1C, it is possible to improve the fixing force of the speaker structural members that are connected to each other. By using the protruding portions 1B and the holes 1C, the relative positional relationship of the speaker structural members in the vibration direction of the diaphragm 30 can be set to a desired positional relationship. In particular, by providing the fixing surface 1D around the protruding portion 1B or the hole 1C, the connecting portions of the speaker structural members 1A that are connected to each other can be fixed while being maintained in a substantially parallel shape.
　突起状部１Ｂと孔部１Ｃを用いることで、複数のスピーカ用構成部材１Ａは、振動板３０の振動方向における所望の位置で、精度良く固定される。突起状部１Ｂが剛性を備えることで、ボイスコイル２１の振動方向にて、位置ズレを生じることを抑止できる。突起状部１Ｂ、孔部１Ｃの周囲に設けられる固定面１Ｄは、ボイスコイル２１の振動方向に沿う面を備える。固定面１Ｄは、平坦な面を備えても構わない。このような、突起状部１Ｂ、孔部１Ｃ、固定面１Ｄを用いることで、振動板３０の振動方向とボイスコイル２１の振動方向におけるスピーカ用構成部材の相対的な位置関係を良好にすることができる。 By using the protruding portion 1B and the hole portion 1C, the plurality of speaker components 1A are accurately fixed at desired positions in the vibration direction of the diaphragm 30. Protrusion-like part 1B is provided with rigidity, and it can control that position shift occurs in the vibration direction of voice coil 21. The fixed surface 1D provided around the protrusion 1B and the hole 1C includes a surface along the vibration direction of the voice coil 21. The fixed surface 1D may include a flat surface. By using the protruding portion 1B, the hole 1C, and the fixed surface 1D, the relative positional relationship of the speaker constituent members in the vibration direction of the diaphragm 30 and the vibration direction of the voice coil 21 is improved. Can do.
　図示の例では、フレーム１２にヨーク２３Ａ、振動板用フレーム１３がボイスコイル２１の振動方向に沿って並べて配置され、固定されている。ヨーク２３Ａは、振動板３０の振動方向における磁気ギャップ２３Ｇの幅を規定する。振動板用フレームは、振動板３０の振動方向における振動板３０の位置を規定する。また、規定された磁気ギャップ２３Ｇ内にボイスコイル２３が配置される。 In the illustrated example, a yoke 23A and a diaphragm frame 13 are arranged on the frame 12 along the vibration direction of the voice coil 21 and fixed. The yoke 23A defines the width of the magnetic gap 23G in the vibration direction of the diaphragm 30. The diaphragm frame defines the position of the diaphragm 30 in the vibration direction of the diaphragm 30. Further, the voice coil 23 is disposed in the defined magnetic gap 23G.
　このボイスコイル２３は、振動方向変換部４０を介して、振動板３０に連結している。この場合、例えば、ヨーク２３Ａと振動板用フレーム１３が、ボイスコイル２１の振動方向、振動板３０の振動方向において所望の位置にされた場合には、ボイスコイル２１と振動板３０のうち、少なくとも一方はボイスコイル２１の振動方向に対して傾いた状態で配置されることを抑止することができる。 The voice coil 23 is connected to the diaphragm 30 via the vibration direction converter 40. In this case, for example, when the yoke 23A and the diaphragm frame 13 are set to desired positions in the vibration direction of the voice coil 21 and the vibration direction of the diaphragm 30, at least of the voice coil 21 and the diaphragm 30. One side can be prevented from being disposed in an inclined state with respect to the vibration direction of the voice coil 21.
　突起状部１Ｂを備える一方のスピーカ用構成部材１Ａ１は、例えば樹脂部材で構成される。樹脂部材としては、光照射（赤外線等）、半田ごてなどの加熱手段により、加熱することで溶ける熱可塑性樹脂、半田などの熱溶融型材料が挙げられる。フランジ部ｂは、フランジ部ｂを支持する支柱部ａの端部に連続的に設けられる。このフランジ部ｂは、例えば、加熱圧接部材で支柱部ａを圧接することで形成できる。特に、互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２を固定する際に、突起状部１Ｂを孔部１Ｃに挿入した状態で、支柱部ａの端部が熱溶融されて、フランジ部ｂが形成される。フランジ部ｂは、支柱部ａの端部に、フランジ部ｂに対応する金型を備える加熱圧接部材を圧接することで、形成されても構わない。これによると、スピーカ用構成部材１Ａ１，１Ａ２を互いに固定・接合することができる。なお、以下に示す図では、加熱する前の支柱部ａが突出した突起状部１Ｂを「１Ｂ（ａ）」と示し、支柱部ａの端部を加熱して溶かしたフランジ部ｂを有する突起状部１Ｂを「１Ｂ（ｂ）」と示す。 One speaker component 1A1 provided with the protruding portion 1B is made of, for example, a resin member. Examples of the resin member include thermoplastic resins that melt when heated by heating means such as light irradiation (infrared rays or the like) and a soldering iron, and hot-melt materials such as solder. The flange part b is continuously provided at the end part of the column part a that supports the flange part b. The flange portion b can be formed by, for example, press-contacting the support column portion a with a heating and pressing member. In particular, when fixing the speaker components 1A1 and 1A2 to be fixed to each other, the end portion of the column portion a is thermally melted in a state where the protruding portion 1B is inserted into the hole portion 1C to form the flange portion b. Is done. The flange part b may be formed by pressing the end part of the support | pillar part a with the heat press-contacting member provided with the metal mold | die corresponding to the flange part b. According to this, the speaker structural members 1A1 and 1A2 can be fixed and joined to each other. In the drawings shown below, the protruding portion 1B from which the support column a before protruding is shown as “1B (a)”, and the protrusion having the flange portion b obtained by heating and melting the end of the support column a. The shaped portion 1B is indicated as “1B (b)”.
　金型を備える加熱圧接部材で形成されたフランジ部ｂは、フランジ部ｂに対面するスピーカ用構成部材１Ａの上面に接していても構わない。また、フランジ部ｂの下面には、スピーカ用構成部材１Ａの上面の表面形状が転写されても構わない。フランジ部ｂの下面に、スピーカ用構成部材１Ａの表面形状が転写されることで、駆動部材２０Ａの振動方向における、互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２の位置ズレを抑止できる。また、スピーカ用構成部材１Ａ１，１Ａ２間でガタツキが生じることを抑止できる。 The flange part b formed by the heating and pressure welding member provided with the mold may be in contact with the upper surface of the speaker component 1A facing the flange part b. Further, the surface shape of the upper surface of the speaker component 1A may be transferred to the lower surface of the flange portion b. By transferring the surface shape of the speaker component 1A to the lower surface of the flange portion b, it is possible to suppress positional deviation of the speaker components 1A1 and 1A2 fixed to each other in the vibration direction of the drive member 20A. In addition, it is possible to suppress the occurrence of rattling between the speaker components 1A1 and 1A2.
　突起状部１Ｂなどの被加熱部材を加熱する手段として、外部加熱手段と内部加熱手段とがある。外部加熱手段は、被加熱部材の外部にある熱源から、熱伝導（熱の移動）によって加熱する方法である。 There are an external heating means and an internal heating means as means for heating a member to be heated such as the protruding portion 1B. The external heating means is a method of heating by heat conduction (transfer of heat) from a heat source outside the member to be heated.
　内部加熱手段は、被加熱部材自身を発熱させる方法である。また、被加熱部材の内部の温度を上昇させるので、加熱したくない部材の温度上昇を抑制できる。このため、加熱したくない部材に変形等が発生することを抑止できる。 The internal heating means is a method for heating the heated member itself. Moreover, since the temperature inside a to-be-heated member is raised, the temperature rise of the member which does not want to heat can be suppressed. For this reason, it can suppress that a deformation | transformation etc. generate | occur | produce in the member which does not want to heat.
　薄型化したスピーカ用構成部材１Ａを、振動板３０の振動方向に沿って積み重ねて、スピーカ装置１を構成する場合がある。この場合、振動板３０の振動方向において、複数のスピーカ用構成部材１Ａを精度良く配置する必要がある。この時、１つのスピーカ用構成部材が溶着時の加熱で変形等してしまうと、複数のスピーカ用構成部材１Ａ間の相対的な位置関係に悪影響が生じてしまう。具体的には、変形した振動板３０（振動系部材）が所望の振動方向に沿って振動できなくなる場合がある。変形したボイスコイル２１（振動系部材）が後述するヨークに接触し、異音が発生する場合がある。フレーム１１が変形し、所定の位置に後述するヨークを配置できなくなる場合がある。この時、ボイスコイル２１と後述するヨークとの接触を誘発させる場合がある。この場合には、内部加熱手段を用いることで、複数のスピーカ用構成部材１Ａの相対的な位置関係を良好にすることができる。 In some cases, the speaker device 1 may be configured by stacking the thinned speaker structural members 1 </ b> A along the vibration direction of the diaphragm 30. In this case, it is necessary to arrange the plurality of speaker components 1A with high accuracy in the vibration direction of the diaphragm 30. At this time, if one speaker component is deformed by heating during welding, a relative positional relationship between the plurality of speaker components 1A is adversely affected. Specifically, the deformed diaphragm 30 (vibration system member) may not be able to vibrate along a desired vibration direction. The deformed voice coil 21 (vibration system member) may come into contact with a yoke, which will be described later, and abnormal noise may be generated. There is a case where the frame 11 is deformed and a yoke described later cannot be disposed at a predetermined position. At this time, a contact between the voice coil 21 and a yoke described later may be induced. In this case, the relative positional relationship between the plurality of speaker components 1A can be improved by using the internal heating means.
　外部加熱手段の具体例としては、熱風式溶着、熱板式溶着、インパルス式溶着、コテ式溶着などが挙げられる。内部加熱手段の具体例としては、高周波誘電加熱法を用いた超音波溶着、集光させた赤外線やレーザービームを用いる光溶着などが挙げられる。 Specific examples of the external heating means include hot air welding, hot plate welding, impulse welding, and iron welding. Specific examples of the internal heating means include ultrasonic welding using a high frequency dielectric heating method, and photo welding using a condensed infrared ray or laser beam.
　特に、内部加熱手段のうち、光溶着は加熱したい被加熱部材の一部のみを実質的に加熱できる。このため、被加熱部材に変形等が生じることを抑止できる。 Particularly, among the internal heating means, the light welding can substantially heat only a part of the heated member to be heated. For this reason, it can suppress that a deformation | transformation etc. arise in a to-be-heated member.
　フランジ部ｂに対面するスピーカ用構成部材１Ａの表面に、表面処理を施しても構わない。表面処理等を施すことで、フランジ部ｂとスピーカ用構成部材１Ａとの密着力を向上させることができる。必要に応じて、フランジ部ｂを形成すると同時に、フランジ部ｂとスピーカ用構成部材１Ａとを一体化させても構わない。互いに固定されるスピーカ用構成部材１Ａ１、１Ａ２との間に、ガタツキが生じない程度に、隙間が形成されても構わない。 The surface of the speaker component 1A facing the flange portion b may be subjected to a surface treatment. By performing the surface treatment or the like, it is possible to improve the adhesion between the flange portion b and the speaker component 1A. If necessary, at the same time as forming the flange portion b, the flange portion b and the speaker component 1A may be integrated. A gap may be formed between the speaker structural members 1A1 and 1A2 fixed to each other to such an extent that no rattling occurs.
　図３及び図４は、スピーカ装置１の平面斜視図を示している（図４は、図３とは異なる方向からみた図である。）。振動板３０を直接又は他の部材（エッジ３１）を介して支持する振動板用フレーム１３は、駆動部２０を支持するフレーム（駆動部用フレーム）１１上に配置されている。図示されたスピーカ装置１は、振動板３０をフレーム１１に対して両側（紙面上、上下）に一対備えている。このスピーカ装置１では、一対の振動板用フレーム１３の間にフレーム１１が配置されている。図示の例では、振動板用フレーム１３は位置決め凸部１３ｂを有し、フレーム１１は位置決め凹部１１ａを有しており、一対の振動板用フレーム１３の間にフレーム１１が配置されている状態で、位置決め凸部１３ｂと位置決め凹部１１ａとが嵌り合っている。 3 and 4 are plan perspective views of the speaker device 1 (FIG. 4 is a view as seen from a direction different from FIG. 3). The diaphragm frame 13 that supports the diaphragm 30 directly or via another member (edge 31) is disposed on the frame (drive part frame) 11 that supports the drive unit 20. The illustrated speaker device 1 includes a pair of diaphragms 30 on both sides (on the paper surface, up and down) with respect to the frame 11.

In the illustrated example, the frame 11 is provided with the protruding portion 1B, and the diaphragm frame 13 is provided with the hole portion 1C. Conversely, the frame 11 is provided with the hole portion 1C, and the diaphragm frame 13 is protruded. You may provide the shape part 1B.

　図６は、スピーカ装置１の内部構造（フレーム１１に各部を配備して、上側の振動板用フレーム１３と磁気回路２３の一部を取り外した状態）を示した説明図である。ボイスコイル２１又はボイスコイル支持部２２は平板状であり、保持部２４に振動自在に支持されている。振動方向変換部４０側における、ボイスコイル２１又はボイスコイル支持部２２の一方の端部に、振動方向変換部４０のボイスコイル用連結部分４３が連結される。振動方向変換部４０のフレーム用連結部分４５がフレーム１１に連結される。振動方向変換部４０の振動板用連結部分４４には振動板３０が連結される。なお、保持部２４側における、ボイスコイル２１又はボイスコイル支持部２２の他方の端部には、外部と電気的に接続する引出線２１－１が取り付けられる。 FIG. 6 is an explanatory diagram showing an internal structure of the speaker device 1 (a state in which each part is arranged on the frame 11 and a part of the upper diaphragm frame 13 and the magnetic circuit 23 are removed). The voice coil 21 or the voice coil support portion 22 has a flat plate shape, and is supported by the holding portion 24 so as to freely vibrate. The voice coil connecting portion 43 of the vibration direction conversion section 40 is connected to one end of the voice coil 21 or the voice coil support section 22 on the vibration direction conversion section 40 side. The frame connecting portion 45 of the vibration direction changing unit 40 is connected to the frame 11. The diaphragm 30 is coupled to the diaphragm coupling portion 44 of the vibration direction converter 40. A lead wire 21-1 that is electrically connected to the outside is attached to the other end portion of the voice coil 21 or the voice coil support portion 22 on the holding portion 24 side.

A plurality of protrusions 1 </ b> B and a plurality of holes 1 </ b> C are arranged side by side along a direction intersecting the vibration direction of the voice coil 21. For this reason, the voice coil 21 and the vibration direction converter 40 can vibrate substantially integrally.
　ボイスコイル２１の振動を、振動方向変換部４０は、効率良く、振動板３０に伝達することができる。突起状部１Ｂ又は孔部１Ｃの近傍に、リンク部分４１は後述する補強部４９を備える。突起状部１Ｂ又は孔部１Ｃの近傍にて、リンク部分４１はボイスコイル２１の振動方向にて駆動力が作用する。この時、リンク部分４１が湾曲してしまい、効率良くボイスコイル２１の振動を伝達できなくなる場合がある。リンク部分４１が補強部４９を備えることで、剛性を備えることができる。そのため、このリンク部分４１を備える振動方向変換部４０は、効率良くボイスコイル２１の振動を振動板３０に伝達することができる。 The vibration direction converter 40 can efficiently transmit the vibration of the voice coil 21 to the diaphragm 30. In the vicinity of the protruding portion 1B or the hole 1C, the link portion 41 includes a reinforcing portion 49 described later. In the vicinity of the protruding portion 1B or the hole 1C, the link portion 41 is driven by a driving force in the vibration direction of the voice coil 21. At this time, the link portion 41 is curved, and the vibration of the voice coil 21 may not be transmitted efficiently. By providing the link portion 41 with the reinforcing portion 49, rigidity can be provided. Therefore, the vibration direction conversion unit 40 including the link portion 41 can efficiently transmit the vibration of the voice coil 21 to the diaphragm 30.

　内側支持部１４は、フレーム１１から振動方向変換部４０に向かって突出しており、振動板３０の振動方向に対して剛性を備える。内側支持部１４は、対向配置されるフレーム１１の２つの部分から突出し、この２つの部分間を橋渡す橋渡し部１５になっている。内側支持部１４には振動方向変換部４０のフレーム用連結部分４５が取り付けられる。振動板用フレーム１３の第１の外周枠部１３－１と第２の外周枠部１３－２の間に、磁気回路３０を支持する駆動部支持部１６が挟持される。 The inner support portion 14 protrudes from the frame 11 toward the vibration direction conversion portion 40 and has rigidity with respect to the vibration direction of the diaphragm 30. The inner support portion 14 protrudes from two portions of the frame 11 arranged to face each other, and serves as a bridge portion 15 that bridges between the two portions. A frame connecting portion 45 of the vibration direction changing portion 40 is attached to the inner support portion 14. A drive unit support unit 16 that supports the magnetic circuit 30 is sandwiched between the first outer peripheral frame unit 13-1 and the second outer peripheral frame unit 13-2 of the diaphragm frame 13.
　図１３に示すスピーカ装置１は、駆動部支持部材１６と振動板用フレーム１３との連結部、振動板３０と振動板用連結部分４４との連結部、フレーム用連結部分４５と内側支持部１４（橋渡し部１５）等に、突起状部１Ｂと孔部１Ｃが設けられる。 The speaker device 1 shown in FIG. 13 includes a connecting portion between the driving portion support member 16 and the diaphragm frame 13, a connecting portion between the diaphragm 30 and the diaphragm connecting portion 44, a frame connecting portion 45 and the inner support portion 14. The projecting portion 1B and the hole portion 1C are provided in the (bridge portion 15) or the like.
　図１４に示す保持部２４は、保持部２４に突起状部１Ｂと孔部１Ｃを適用した場合の変形例を示したものである。図示された保持部２４の一部は、図６に示される保持部の裏面を示したものである。図示の例では、保持部２４が２つの異なる一部分のうち、一方の一部分が突起状部１Ｂを備え、他方の一部分が凹部１Ｆ（孔部１Ｃ）を備えている。突起状部１Ｆは、ボイスコイル２１の振動方向に対して交差する方向に延在する。保持部２４の一方の一部分は、ボイスコイル２１を振動自在に支持する。 The holding part 24 shown in FIG. 14 shows a modification when the protruding part 1B and the hole part 1C are applied to the holding part 24. A part of the illustrated holding unit 24 shows the back surface of the holding unit shown in FIG. 6. In the example shown in the figure, the holding portion 24 includes a protruding portion 1B of two different portions, and the other portion includes a concave portion 1F (hole portion 1C). The protruding portion 1 </ b> F extends in a direction that intersects the vibration direction of the voice coil 21. One part of the holding part 24 supports the voice coil 21 so that it can vibrate.
　保持部２４の他方の一部分は、フレーム１１に支持されている。凹部１Ｆは、壁部１Ｆ－１と支持面部１Ｆ－２とを備える。凹部１Ｆの壁部１Ｆ－１と支持面部１Ｆ－２は、突起状部１Ｂを収容する空間を構成している。この突起状部１Ｂの端部は溶融され、フランジ部ｂが形成される。凹部１Ｆは、突起状部１Ｂに形成されるフランジ部に対応する、形状を備えている。具体的には、凹部１Ｆは支柱部ａの外周部に対面する壁部１Ｆ－１を備える。この壁部１Ｆ－１の間における間隙は、突起状部１Ｂの端部近傍における間隙より小さく構成されている。このため、突起状部１Ｂに設けられるフランジ部は、凹部１Ｆを有する保持部２４の他方の一部分に固定される。よって、ボイスコイル２１が振動しても、保持部２４の一方の一部分は、保持部２４の他方の一部分に対し、安定に固定される。また、位置ズレの発生が抑止される。また、凹部１Ｆは孔部１Ｃであっても構わない。また、固定面１Ｄは、保持部２４の一方の部分、他方の部分に設けられている。図示の例では、突起状部１Ｂと凹部１Ｆとが保持部２４の一つの角部の近傍に設けられているが、これに限定せず４つの角部の近傍に設けても構わない。 The other part of the holding part 24 is supported by the frame 11. The recess 1F includes a wall 1F-1 and a support surface 1F-2. The wall portion 1F-1 and the support surface portion 1F-2 of the recess 1F constitute a space for accommodating the protruding portion 1B. The end of the protruding portion 1B is melted to form the flange portion b. The concave portion 1F has a shape corresponding to the flange portion formed in the protruding portion 1B. Specifically, the concave portion 1F includes a wall portion 1F-1 facing the outer peripheral portion of the support column portion a. The gap between the wall portions 1F-1 is smaller than the gap in the vicinity of the end of the protrusion 1B. For this reason, the flange part provided in the protruding part 1B is fixed to the other part of the holding part 24 having the recess 1F. Therefore, even if the voice coil 21 vibrates, one part of the holding part 24 is stably fixed to the other part of the holding part 24. In addition, the occurrence of positional deviation is suppressed. Further, the recess 1F may be the hole 1C. Further, the fixing surface 1D is provided on one part and the other part of the holding part 24. In the illustrated example, the protruding portion 1B and the concave portion 1F are provided in the vicinity of one corner portion of the holding portion 24. However, the present invention is not limited to this and may be provided in the vicinity of four corner portions.
　本発明の実施形態に係るスピーカ装置１は、突起状部１Ｂと孔部１Ｃによってスピーカ用構成部材１Ａ（１Ａ１，１Ａ２）相互を固定するので、接着剤の硬化時間によるスピーカ装置の生産性低下を解消することができる。また、スピーカ装置の製造工程において、接着剤が完全に硬化するまで構成部材同士の位置を固定することによる煩雑性を解消することができる。また、高音量化と薄型化を両立させることが可能な振動方向変換部４０を備えたスピーカ装置において、駆動部材２０Ａ（ボイスコイル２１）の振動に伴う外力（剪断力）に対して強固な固定状態が維持でき、固定位置がずれることでスピーカ用構成部材１Ａ（１Ａ１，１Ａ２）同士が衝突して異音を発生するといった不具合を抑止することができる。 Since the speaker device 1 according to the embodiment of the present invention fixes the speaker components 1A (1A1, 1A2) to each other by the protruding portion 1B and the hole portion 1C, the productivity of the speaker device is reduced due to the curing time of the adhesive. Can be resolved. Further, in the manufacturing process of the speaker device, it is possible to eliminate the troublesomeness caused by fixing the positions of the constituent members until the adhesive is completely cured. Further, in the speaker device including the vibration direction converter 40 capable of achieving both high volume and thinning, the speaker device is firmly fixed against an external force (shearing force) caused by vibration of the driving member 20A (voice coil 21). Therefore, it is possible to prevent a problem that the structural members 1A (1A1, 1A2) for speakers collide with each other and generate abnormal noise due to the fixed position being shifted.
　特に、振動方向変換部４０を介して駆動部材２０Ａの振動を振動板３０に伝えるスピーカ装置１では、スピーカ用構成部材１Ａ（１Ａ１，１Ａ２）相互の固定面１Ｄ（１Ｄ１，１Ｄ２）が駆動部材２０Ａの振動方向に沿って形成されることが多い。このようなスピーカ装置１では、駆動部材２０Ａの振動が固定面１Ｄ（１Ｄ１，１Ｄ２）に対して剪断力として作用することになる。そのため、固定面１Ｄ１に駆動部材２０Ａの振動方向に対して交差する方向に突出する突起状部１Ｂを設けて、これを固定面１Ｄ２の孔部１Ｃに挿入する。これにより、駆動部材２０Ａの振動によって生じる剪断力に対して突起状部１Ｂが抵抗となり、固定状態を強固に維持することができる。 In particular, in the speaker device 1 that transmits the vibration of the drive member 20A to the diaphragm 30 via the vibration direction conversion unit 40, the speaker-constituting members 1A (1A1, 1A2) are fixed to each other by the fixed surfaces 1D (1D1, 1D2). It is often formed along the vibration direction. In such a speaker device 1, the vibration of the drive member 20A acts as a shearing force on the fixed surface 1D (1D1, 1D2). Therefore, a protrusion 1B protruding in a direction intersecting the vibration direction of the drive member 20A is provided on the fixed surface 1D1, and this is inserted into the hole 1C of the fixed surface 1D2. Thereby, the protruding portion 1B becomes a resistance against the shearing force generated by the vibration of the driving member 20A, and the fixed state can be firmly maintained.
　また、突起状部１Ｂの端部にフランジ部ｂを形成することで、フランジ部ｂが互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２の突起状部１Ｂの突出方向における位置ずれを抑止する。駆動部材２０Ａの振動方向に対しては突起状部１Ｂの支柱部ａが抵抗となる。また、駆動部材２０Ａの振動方向とは異なる方向に振動する振動板３０の振動に対しては突起状部１Ｂのフランジ部ｂが抵抗となる。このため、振動方向変換部４０を介して駆動部材２０Ａの振動を振動板３０に伝えるスピーカ装置１において、スピーカ用構成部材１Ａ１，１Ａ２相互の固定を強固に維持することができる。 Further, by forming the flange portion b at the end portion of the protruding portion 1B, the positional deviation in the protruding direction of the protruding portion 1B of the speaker structural members 1A1 and 1A2 to which the flange portion b is fixed is suppressed. The strut portion a of the protruding portion 1B serves as a resistance with respect to the vibration direction of the driving member 20A. Further, the flange portion b of the protruding portion 1B becomes a resistance against the vibration of the diaphragm 30 that vibrates in a direction different from the vibration direction of the drive member 20A. For this reason, in the speaker device 1 that transmits the vibration of the drive member 20A to the diaphragm 30 via the vibration direction converter 40, the speaker components 1A1 and 1A2 can be firmly fixed to each other.
　また、複数の突起状部１Ｂが、駆動部材２０Ａの振動方向に沿って並べて配置されている。このため、駆動部材２０Ａの振動に伴う剪断力が複数の突起状部１Ｂにより低減される。また、複数の突起状部１Ｂにより、互いに固定されるスピーカ用構成部材１Ａ１，１Ａ２相互の固定状態が強固に維持される。また、スピーカ装置１の耐久性を向上させることができる。 Further, a plurality of protruding portions 1B are arranged side by side along the vibration direction of the drive member 20A. For this reason, the shearing force accompanying the vibration of the drive member 20A is reduced by the plurality of protruding portions 1B. Moreover, the fixed state of the speaker structural members 1A1 and 1A2 fixed to each other is firmly maintained by the plurality of protruding portions 1B. Moreover, the durability of the speaker device 1 can be improved.

FIG. 2B shows an automobile 3 provided with the speaker device according to the embodiment of the present invention. In the automobile 3 shown in the figure, the space in the vehicle can be expanded by making the speaker device 1 thinner. In particular, in the case where the speaker device 1 according to the embodiment of the present invention is installed in the door panel, the protrusion of the door panel is eliminated and the operation space for the driver can be expanded. In addition, since sufficient sound output can be obtained, music and radio broadcasting can be enjoyed comfortably in the car even during high-speed driving with a lot of noise.
　また、スピーカ装置１を備える建築物として、人の居住を用途とする住宅（建築物）や会議、講演会、パーティー等、多数の人数を収容して催しを行うことができるホテル、旅館や研修施設等（建築物）にスピーカ装置１を設置した場合、スピーカ装置１の設置に必要な厚さスペースを小さくできるので、不要なスペースを削除でき、スペースを有効に活用することができる。また、近年、プロジェクターや大画面テレビ等の普及に伴い、音響・映像設備を備える居室を設ける例が見られるようになっており、一方で音響・映像設備を備える居室を設けずに、リビングルーム等をシアタールームとして使用するケースも見られる。このようなケースにおいても、スピーカ装置１を用いることで、簡易にリビングルーム等をシアタールーム化でき、さらにリビングルーム内の空間を有効に活用することが可能である。なお、スピーカ装置１の配置場所は、例えば、居室内の天井や壁等が挙げられる。 In addition, as a building equipped with the speaker device 1, a hotel, inn or training that can accommodate a large number of people, such as a house (building) intended for the residence of people, a meeting, a lecture, a party, etc. When the speaker device 1 is installed in a facility or the like (building), the thickness space necessary for the installation of the speaker device 1 can be reduced, so that unnecessary space can be deleted and the space can be used effectively. In recent years, with the widespread use of projectors and large-screen televisions, there are examples of providing rooms with audio / video equipment, while living rooms without audio / video equipment are provided. In some cases, etc. are used as theater rooms. Even in such a case, by using the speaker device 1, it is possible to easily convert a living room or the like into a theater room and to effectively use the space in the living room. Note that the speaker device 1 may be arranged at, for example, a ceiling or a wall in a living room.
