Packing ring 74 can (that is, can be against attached after being compressed by conductive foam, conductive fiber and/or other conductive structures The elastomer structure that nearly structure is expanded outwardly) formed.Illustrative cross section available for the conductive foam structure for forming packing ring 74 Side view is shown in Fig. 9.As shown in Figure 9, packing ring 74 can be by the layer 148 that is such as coupled in a stack etc One or more froth beds are formed.The opening (for example, the rectangular aperture formed in rectangular foam layer is stacked) of such as opening 156 It can be used for layer being configured to the structure as packing ring 74.(in Fig. 9 diagram, the material in open area 156 does not have also It is removed.)

Every layer in froth bed 148 can include foam substrate layer 146.The foam of layer 146 can contribute to ensure pad Circle 74 may be used as the closed-cell foam for being acoustically isolated packing ring around speaker port 74.Closed-cell foam does not have through bubble The opening of the main body of foam, therefore closed-cell foam effectively stops sound.However, the presence of closed-cell foam middle hole wall can cause by Metal or other conductive materials with formed by way of the current path of foam deposit to it is challenging in foam.Therefore, Froth bed 146 can be provided through the metal throuth hole of such as through hole 150 of closed-cell foam etc.Metal throuth hole 150 leads layer 148 Electricity (that is, the layer 146 with through hole 150 is used as the conductive foam layer in packing ring 74).Conductive adhesive layer 152 can be used for one The layer 148 of layer, two layers or more layer or three layers or more is coupled together and is couple to conductive fiber 154.To be used in packing ring The quantity of layer 148 in 74 can be determined by the thickness of required packing ring 74.Layer 148 can be 0.5mm thick, exceed 0.5mm is thick, less than 0.5mm thickness, etc..Fiber 154 can with the outer surface of surrounding layer 148 it is some or all of come wrap up with increase The conductance of cushioning circle 74.Conductive fiber 154 can be handled by metallic fiber, the plastic optical fibre of coating metal, with metallic particles The formation such as fiber and/or other conductive materials for crossing.If desired, layer 148 can be by being coated with metal or other are suitable The open cell plastic foam of conductive elastomer structure is formed.Packing ring 74 is formed using the closed-cell foam with metal throuth hole is only It is illustrative.

The antenna 40 being aligned with groove 30 (for example, groove 30-1 or groove 30-2) in the illustrative location in housing 12 Cross-sectional side view be shown in Figure 10.As shown in Figure 10, before antenna resonating element 50 and dielectric support structure 76 Can be on direction 164 to groove 130, so that the aerial signal from antenna 40 can pass through groove 30.Such as structure 160 Conductive structure with 162 etc can be used for the antenna ground trace 52 of antenna 40 being grounded to metal lower shell body 12B.Structure 162 can be conductive adhesive layer or other conductive materials.Structure 160 can contribute to press up on antenna 40 to cause Packing ring 74 is compressed between the opposed bottom face of the ground connection 52 on the upper surface of carrier 76 and metal lower shell body 12B upper part Conductive foam layer.It is preferred that, the opening at the center of packing ring 74 and speaker openings 28 and speaker port 72 in housing 12B Alignment.Loudspeaker 70 is aligned with the housing speaker port formed by opening 28 allow the sound from speaker port 72 from Open up standby 10 (for example, when covering 12A openings).Packing ring 74 forms acoustic seal around speaker port 72 and prevents sound Leak into the gap between antenna 40 and housing 12B.Packing ring 74 is also formed is shorted to housing by the antenna ground 52 of antenna 40 The conductive path of the downside of 12B upper part, so as to prevent aerial signal from entering housing 12B inside via path 166.This has Help ensure to will not interfere with the circuit of the inside of equipment 10 by the aerial signal that antenna 40 is transmitted, such as display 14 Display circuit, control circuit 30 etc..

Upper shell 12A can have such as part 12AR rear part, and it is when equipment 10 is in lid closed configuration with Separately enough amount, to form gap 30, and thereby allows antenna 40 to transmit and receive wireless signal to housing 12B.Figure 11 is shown The equipment 10 in configuration is opened in illustrative lid, wherein upper shell (lid) 12A rotates to opening around hinge axis 22 Position.In Figure 11 illustrative configuration, groove 30 has upper and bottom section (except being located at the left side at diverse location along axle 22 Part and right half).Aerial signal can be either through the upper part of groove 30, through the lower part of groove 30 or through Figure 11 Upper groove and lower groove 30 both.With such arrangement, each antenna and a pair of antenna aperatures (that is, upper groove and lower groove) are related Connection.If desired, lid open position and lid closure position both in, each antenna can by single groove come Operation.The illustrative configuration for Figure 11 that the position of the wherein opening lid of equipment 10 creates a pair of slot apertures for each antenna is only to say Bright property.

Housing 12A can apply a variable impedance load relative to the position of the change of antenna 40 on antenna 40. As a result, because housing 12A position is adjusted by a user (for example, viewing in order to optimize display 14 in housing 12A) and causes Antenna performance can be with off resonance.This effect is shown that wherein antenna performance (standing-wave ratio SWR) has been depicted in by Fig. 2 diagram The function of running frequency f at 2.4GHz in illustrative communication band interested.Figure 12 curve is shown capacitor 102 The influence for the position for influenceing and showing lid being incorporated into the signal path between transceiver 90 and antenna 40.Curve 170 It is shown in which the property of antenna 40 covered in the configuration that 12A has been omitted relative to 110 ° of angles of horizontal opening and capacitor 102 Energy.Curve 170' shows that the antenna performance arranged when lid 12A closures (that is, be orientated 0 °) for such antenna can be with How off resonance.Curve 168, which corresponds to wherein to there are capacitor 102 and cover 12A, to be in the configuration of 110 ° of open position Antenna 40 operation.In the case where there are capacitor 102, such as relative to curve 170 shape by antenna resonance curve Shown in 168 shape widened, the bandwidth of antenna 40 is widened.Even if the influence widened of capacitor 102 is ensured as lid 12A During closure (curve 170'), antenna 40 also will satisfactorily be run at frequency of the continuation desired by 2.4GHz frequency bands.

In Figure 13 illustrative figure, antenna efficiency be depicted as lid (that is, housing 12A is relative to housing 12B for position Position) function.Curve 174 corresponds to the antenna arrangement that wherein capacitor 102 has been omitted.Show the lid position of reduction The curve 172 of sensitiveness corresponds to the antenna arrangement for wherein having included capacitor 102.

As shown in Figure 12 and 13 example, contribute to reduce by 40 pairs of lid position off-resonance effects of antenna using electric capacity 102 Susceptible.If desired, other lid off resonance susceptible reduction circuits can be coupled in transceiver 90 and antenna Between 40 feed.The response of antenna 40 is widened using capacitor 102 and thereby the influence of reduction antenna off resonance is only illustrative 's.

Another method for reducing the sensitiveness of the antenna off resonance of 10 pairs of lid location sensitives of equipment is directed to use with supervisory circuit (for example, impedance monitoring circuit, received signal strength supervisory circuit etc.) come monitor antenna 40 performance and/or cover 12A position.
